2-1 Hunter:  Hunters alone are blamed for the decline in Greenrock National Forest’s deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.  In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.

In the hunter’s argument, the boldface portion plays which of the following roles?

• It is the main conclusion of the argument.
• It is an objection that has been raised against the main conclusion of the argument.
• It is a judgment that the argument opposes.
• It is a finding that the argument seeks to explain.
• It provides evidence in support of the main conclusion of the argument.
  

2-2 Which of the following most logically completes the passage?

Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo dose not have the same financial incentive to adopt such a policy, because ______.

• early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life
• the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol
• RenCo has significantly more employees than Garnet has
• RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees
• the average length of time an employee stays with RenCo is less than it is with Garnet
  

2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.  Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.

Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?

• The effect noted in the studies is not limited to patrons who have credit cards.
• Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.
• In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
• In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
• The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.
  

2-4 Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.

In the economist’s argument, the two boldfacedportions play which of the following roles?

• The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.
• The first states the conclusion of the economist’s argument; the second supports that conclusion.
• The first supports the environmentalists’ conclusion; the second states that conclusion.
• The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument.
• Each supports the conclusion of the economist’s argument.
  

2-5 (Weaken题变体) Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.

Criticism:  For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.

Which of the following, if true, provides the best basis for a rebuttal of the criticism?

• Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.
• A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.
• A significant proportion of the residents of the city live in buildings that do not have yards.
• It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping.
• Some homeowners use more water to maintain their yards than they use for all other purposes combined.
  

2-6 Which of following most logically completes the argument?

The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back.  Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______.

• some prehistoric cave paintings in France also depict other animals as having a hump
• fossils of the giant deer are much more common in Ireland than in France
• animal humps are composed of fatty tissue, which dose not fossilize
• the cave paintings of the giant deer were painted well before 16,000 years ago
• only one currently existing species of deer has any anatomical feature that even remotely resembles a hump
  

2-7 Shipping Clerk:  The five specially ordered shipments sent out last week were sent out on Thursday.  Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.

If the shipping clerk’s statements are true, which of the following must also be true?

• At least one of the shipments sent to Truax Construction last week was specially ordered.
• At least one of last week’s specially ordered shipments did not consist of building supplies.
• At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
• At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
• At least one of the shipments sent to Truax Construction last week was sent out before Friday.
  

2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.

The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?

• The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
• Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
• The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
• The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
• The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.
  

2-9 Newspaper editorial:

In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.

Which of the following is an assumption on which the argument depends?

• Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
• Former inmates are no more likely to commit crimes than are members of the general population.
• The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
• Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
• The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.
  

2-10 Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.

Scott:  The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler’s decline.

Which of the following, if true, most seriously calls Scott’s hypothesis into question?

• The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.
• The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.
• The drop in the population of the spruce budworm is expected to be only temporary.
• Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations.
• Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.

2-1 Hunter:  Hunters alone are blamed for the decline in Greenock National Forest’s deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.  In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.
In the hunter’s argument, the boldface portion plays which of the following roles?
A.        It is the main conclusion of the argument.
B.        It is an objection that has been raised against the main conclusion of the argument.
C.        It is a judgment that the argument opposes.
D.        It is a finding that the argument seeks to explain.
E.        It provides evidence in support of the main conclusion of the argument.
 
2-2 Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo does not have the same financial incentive to adopt such a policy, because ______.
A.        early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life（跟R有无经济动机给员工提供跟G一样的医保无关）
B.        the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol（无关，跟mass media有啥关系，不能解释为啥G公司不给员工弄医保）
C.        RenCo has significantly more employees than Garnet has（不能解释，反而削弱了逻辑关系）
D.        RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees（咋可能，都是人）
E.        the average length of time an employee stays with RenCo is less than it is with Garnet（有力度解释了为啥R没有动机，因为员工工作时间短）
前提：长期不管高胆固醇，治疗成本更高
结论：G公司帮员工即检查又治疗降低成本，R公司却没有经济动机这么做
 
2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.  Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
A.        The effect noted in the studies is not limited to patrons who have credit cards.（跟patron的范围无关）
B.        Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.（反过来应证了自我感觉对消费的影响）
C.        In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.（削弱，说明实验无效，信用卡没能激发出“自我感觉”）
D.        In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card. （削弱，说明信用卡没能激发出自我感觉）
E.        The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.（跟信用卡牌子无关）
前提：自我感觉会影响人们的消费情况，看见信用卡能够让人们产生这种感觉
结论：看见信用卡让人们自我感觉良好的，给的tips多 
2-4 Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
In the economist’s argument, the two boldfaced portions play which of the following roles?
A.        The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.
B.        The first states the conclusion of the economist’s argument; the second supports that conclusion.
C.        The first supports the environmentalists’ conclusion; the second states that conclusion.
D.        The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument.
E.        Each supports the conclusion of the economist’s argument.
 
2-5 (Weaken题变体) Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.
Criticism:  For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.
Which of the following, if true, provides the best basis for a rebuttal of the criticism?
A.        Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.（进一步加强批评者的反对意见，不用换，加装一个设备就行）
B.        A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.（加强，引入其他因素，节约的不只是水费，还有其他额外开销如化肥）
C.        A significant proportion of the residents of the city live in buildings that do not have yards.（加强，全市有院子的少，转化的性价比更低，不合适了就）
D.        It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping. （加强了批评者，因为两种landscapes都一样）
E.        Some homeowners use more water to maintain their yards than they use for all other purposes combined.（加强）
前提：改造院子的景观为节水型的省的钱很少
结论：这么干不省钱 
2-6 Which of following most logically completes the argument?
The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back.  Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______.
A.        some prehistoric cave paintings in France also depict other animals as having a hump（跟other animals无关）
B.        fossils of the giant deer are much more common in Ireland than in France（跟这种deer在哪里无关）
C.        animal humps are composed of fatty tissue, which dose not fossilize（刚好解释了gap）
D.        the cave paintings of the giant deer were painted well before 16,000 years ago（跟壁画啥时候画的无关）
E.        only one currently existing species of deer has any anatomical feature that even remotely resembles a hump（跟现存的deer的特征无关）
前提：壁画里的有角，考古发掘的没有
结论：不能说明壁画错了（没有角） 
2-7 Shipping Clerk:  The five specially ordered shipments sent out last week were sent out on Thursday.  Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.
If the shipping clerk’s statements are true, which of the following must also be true?
A.        At least one of the shipments sent to Truax Construction last week was specially ordered.
B.        At least one of last week’s specially ordered shipments did not consist of building supplies.
C.        At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
D.        At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
E.        At least one of the shipments sent to Truax Construction last week was sent out before Friday.
 
2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.
The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?
A.        The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.（吸烟的数量没减少，所以吸入的焦油也不减少）
B.        Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.（无关）
C.        The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.（应该增加，说反了）
D.        The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.（跟戒烟成功人数无关
E.        The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.（戒烟成功的人数反而应该减少）
事实：吸烟导致的疾病由焦油导致；尼古丁让吸烟者无法戒烟
前提：吸烟上瘾是因为尼古丁
结论：减少每只香烟的尼古丁含量反而导致吸烟数量增加 
2-9 Newspaper editorial:
In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor’s ultimate goal, since after being released from prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
A.        Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.（无关）
B.        Former inmates are no more likely to commit crimes than are members of the general population.（之前的罪犯不比大众更容易犯罪，与逻辑链无关）
C.        The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.（取非削弱了）
D.        Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.（跟高中/大学级别课程无关）
E.        The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.（无关）
前提：？
结论：取消监狱的大学课程能够让进服刑人员出狱后更容易再次犯罪 
2-10 Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.
Scott:  The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler’s decline.
Which of the following, if true, most seriously calls Scott’s hypothesis into question?
A.        The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.（不吃这个虫子的，也减少了，说明是植被）
B.        The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.（跟虫子减少的原因无关）
C.        The drop in the population of the spruce budworm is expected to be only temporary.（跟虫子减少的时间长短无关）
D.        Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations.（挑战题目给定信息，必错）
E.        Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.（跟其他种类的鸟无关）
前提：？
结论：鸟少了不是因为植被，而是因为食物少了

A：这是一个【常识】，即针对R/G来说是一样的，所以这不可能是让G买、R不买的原因
B：明显无关
C：员工人数无关
D：R员工得病率不会比G员工更高，G能save money是因为early treatment减少了后期治疗的巨额费用，而不是因为G的员工得病率高

总结：比昨天做题较顺利，读不懂的题目减少，第9题部分未读懂影响做题，其他不影响做题。7题花时间较多，主要是误解题目，8题也比较花时间

2-1 90s A
黑脸题：背景:狩猎导致鹿数量下降
转折：熊也会影响鹿的数量。
理由：熊数量上升，并且发现熊吃鹿
分析：黑脸与前面内容转折（yet），后面内容为熊吃鹿的细节支撑黑脸熊对鹿的减少起作用。顾选择A

补充题，背景:有两个人給员工体检。G检测员工的c含量并治疗C含量过高的员工
原因：这一举措给C省钱了因为C含量过高到后期会造成昂贵费用
矛盾：然而R并没这样做，是因为：xxx
A早期针对C的治疗并不能完全消除后期发病可能性。如果这样是反驳G，并不是C不买的原因。错
B电视节目鼓励人们摄入低C食品。无关选项。错
C R 比G雇员多，那么R更应该买，错
D R雇员的C含量不像G一样高，这个选项又迷惑性，但是说的是C高以后对未来的影响，现在不高不代表以后不高
E 平均工龄R少于G。因为上文讲的是C高时间长以后，关键词many years，如果工龄短，即使C高了也无所谓，发病已经离职。对

2-3 90s B 本题原来做过
支持题 背景：研究发现刷卡顾客通常会付更多的小费，当账单放在引有卡片logo的纸上时。
矛盾：科学家认为人们看到自己卡片logo的时候更愿意多付款
原因：是因为这提醒他们刷卡的购买力比现金强
A研究不仅限于那些用信用卡的客户。无关选项，错
B有信用卡还款压力的客户当看到卡片logo的时候会少给小费。多给原因是觉得自己有消费能力，那么从另一方面说明没消费能力就少给。对
C付现金的客户没有信用卡，无关选项，错
D给现金的客户给的钱比信用卡多，削弱原文，错。

A。TC至少有一个为特殊包裹。对，因为3个周五发的有补给
B至少有一个特殊包裹不含补给，对，就是TC收到的不含的那个。。
C至少有一个区TC的包裹不是周四发的。错应该为不是周五
D至少有一个区TC的包裹是周五发的。错，如果都为周四并且3含1不含也可以
E至少有一个TC的包裹在周五之前发，。对，因为周五的都有补给，TC收到了无补给的，那么肯定有一个周五之前的。

支持题 背景 大部分吸烟的病由于摄入烟内的tar引起，尼古丁是人们难以戒烟的原因。
措施为 了降低吸烟疾病的发生率，S准备将烟中尼古丁含量降低一半。
矛盾 但是尼古丁成瘾的人说说如果降低一半尼古丁含量，他们会吸更多的烟
A。已经尼古丁成瘾的人摄入tar的量不会减少。对，因为吸更多的烟，即使每根烟的尼古丁少了，但是吸得烟多了。对
B还未尼古丁成瘾的人会比五年前吸收更多的烟。与文章无关，错。
C吸烟者的患病率五年内会下降。主要讲的是尼古丁含量变化，无关
D。 尝试戒烟的人数五年内会下降。无关
E。未来五年内戒烟的人会比之前五年多。无关


2-9 180s A
前提题 背景 为了降低犯罪率，政府对监狱和罪犯采取了更严格的措施。这种措施之一是拒绝其接受之前所学的大学课程（这句比较关键但是不大理解），
矛盾：这方法效果不好，因为自从被释放后，接收教育的人犯罪率比其他人低的多

A在监狱中没能上大学课程不会阻碍其本身可能所犯的罪（没大读懂，意思应该是上不上课和其犯罪无关）。对（排除法，没大理解该项）
B 之前的罪犯不会比同龄人可能犯罪 和同龄人无关，错
C 选择上大学课程的罪犯不会已经比同龄人低犯罪率 本选项和A纠结，但是这个应该不是前提，因为在文章后面也说到了。另外应该和犯罪率没有关系。即使犯罪率低也不会影响实验开展。错
D学习高中可能。。。。无关，本文未提到高中课程，错
E政府的最终目标是通过说服人们采取了针对监狱的措施提高支持率。无关，错

B，sb的降低是因为一种传染自身但是不传染鸟的病。传染鸟才选，不传染不选。主要探讨的是sb和w的数量关系
C。sb的降低是暂时的。正因为是暂时的，所以对鸟类的影响有限，不是w减少的主要原因，对

2-1 Hunter:  Hunters alone are blamed for the decline in Greenrock National Forest’s deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.  In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.

A.        It is the main conclusion of the argument.
B.        It is an objection that has been raised against the main conclusion of the argument.

2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.  Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
A.        The effect noted in the studies is not limited to patrons who have credit cards.
B.        Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.
C.        In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
D.        In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.

2-4 Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
In the economist’s argument, the two boldfacedportions play which of the following roles?
A.        The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.
B.        The first states the conclusion of the economist’s argument; the second supports that conclusion.
C.        The first supports the environmentalists’ conclusion; the second states that conclusion.

2-5 (Weaken题变体) Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.
Criticism:  For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.
Which of the following, if true, provides the best basis for a rebuttal of the criticism?
A.        Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.
B.        A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.
C.        A significant proportion of the residents of the city live in buildings that do not have yards.

2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.
The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?
A.        The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
B.        Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
C.        The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
D.        The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.

2-9 Newspaper editorial:
In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
A.        Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
B.        Former inmates are no more likely to commit crimes than are members of the general population.
C.        The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
D.        Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
E.        The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

2-10 Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.
Scott:  The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler’s decline.
Which of the following, if true, most seriously calls Scott’s hypothesis into question?
A.        The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.
B.        The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.
C.        The drop in the population of the spruce budworm is expected to be only temporary.
D.        Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations.
E.        Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.

2-1 Hunter:  Hunters alone are blamed for the decline in Greenrock National Forest’s deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.  In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.
In the hunter’s argument, the boldface portion plays which of the following roles?
A.        It is the main conclusion of the argument.
B.        It is an objection that has been raised against the main conclusion of the argument.
C.        It is a judgment that the argument opposes.
D.        It is a finding that the argument seeks to explain.
E.        It provides evidence in support of the main conclusion of the argument.
Time: 0’30
P: hunters are blamed
Counter P：black bear population increases; examination evidence
Counter C: black bear 也是其中一个原因

2-2 Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo dose not have the same financial incentive to adopt such a policy, because ______.
A.        early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life (早期治疗不能避免长期不得，那G公司的policy就没有用了，直接说明这个方案的缺点)
B.        the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol （说个人饮食习惯，和为什么R不采用G类似的policy无关）
C.        RenCo has significantly more employees than Garnet has (如果有更多的员工，那更应该考虑这个方案/其次我们不知道这些员工是否都是长期工还是说里面包括了实习生和合约工)
D.        RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees （unlikely to have higher level不代表不会有，就像说你涨价了利润会低但不代表你不涨价利润会高）
E.        the average length of time an employee stays with RenCo is less than it is with Garnet （平均每个员工的在职时间不长说明R不需要去担心员工的长期健康因为不会损害R的利益，这个也解释了为什么R不会去采用）
time: 1’23
P1: G 给员工做cholesterol测试和治疗，长远来说可以省钱 （测试治疗LT money saving）
P2: R没有这个省钱的动机 (?no incentive)
思路：解释为什么明明可以省钱而却没有这个动机省钱的原因

2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.  Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
A.        The effect noted in the studies is not limited to patrons who have credit cards. （扩大讨论范围）
B.        Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo. （反因反果来加强说明越是有能力的看到logo付的tips就会越多）
C.        In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards. （讲用现金付钱和credit logo无关）
D.        In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card. （无关比较）
E.        The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared. （讲一个specific credit card type，偷换概念）
Time: 1’43
P: tips more with logo
C: spending power > what they have when they see a logo
思路：logo 可以提醒消费者他们的purchasing power, 所以反之 spending power< what they have, 那么他们肯定就不会付这么多小费了













2-4 Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
In the economist’s argument, the two boldfacedportions play which of the following roles?
A.        The first supports the conclusion of the economist’s argument; the second calls that conclusion into question. （2个bf都是environmentalist观点）
B.        The first states the conclusion of the economist’s argument; the second supports that conclusion. （not economist, its environmentalist）
C.        The first supports the environmentalists’ conclusion; the second states that conclusion. (bf1说明了可以赚很多钱，但是T不加入，因此bf2得出结论说t不出于利益考虑)
D.        The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument. （Not econ, environ）
E.        Each supports the conclusion of the economist’s argument. (same)

2-5 (Weaken题变体) Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.
Criticism:  For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.
Which of the following, if true, provides the best basis for a rebuttal of the criticism?
A.        Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes. （加强项说明B说的是错误的）
B.        A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape. （传统的除了花多的水钱，其他的费用也高于省钱的装置，所以传统的overall cost>省钱装置装修的费用）
C.        A significant proportion of the residents of the city live in buildings that do not have yards. （无关概念）
D.        It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping. （省钱的和传统的装修费都差不多，但是不能说明后期省钱的在其他费用上能比传统的省钱）
E.        Some homeowners use more water to maintain their yards than they use for all other purposes combined. （无关比较）
Time: 2’36
P: water-conserving landscapesave money, save water
Counter p: 即使换了也只能省少于20$的费用，所以装和不装没有区别
思路：看清题干问什么！！！问的是削弱criticism的观点，说明装了省钱的确实能省一大笔而不是那区区20块
错选了A, 看到题干以为是在问这个rebuttal里面能最好支持criticism的答案。之后才发现是对于criticism的反驳削弱











2-6 Which of following most logically completes the argument?
The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back.  Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______.
A.        some prehistoric cave paintings in France also depict other animals as having a hump (其他动物都有，那会不会是一种画画手法，可能说明那个鹿压根没有hump，但还是有不确定性)
B.        fossils of the giant deer are much more common in Ireland than in France （无关比较，我们不需要知道数量的多少）
C.        animal humps are composed of fatty tissue, which dose not fossilize （解释了为什么Humps会在画上出现而不会在化石上出现的原因，解决了矛盾）
D.        the cave paintings of the giant deer were painted well before 16,000 years ago （时间无关，除非说hump会随着时间变化然后消失，重点在于对Hump的解释而不是时间）
E.        only one currently existing species of deer has any anatomical feature that even remotely resembles a hump （和现在有一种鹿有相似，无关）
Time：1‘34
这题和昨天做的Bone flute很像，都是讲化石，所以每次说到化石可以想一想化石的完整性
P: 这个鹿在P时期画的时候有个hump/化石出土的时候却没有
C: 不能直接否定画
思路：因为结论说不能否定画，所以可以解释一下为什么画上有但是出土没有，会不会是因为别的原因导致的化石上没有hump

















2-7 Shipping Clerk:  The five specially ordered shipments sent out last week were sent out on Thursday.  Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.
If the shipping clerk’s statements are true, which of the following must also be true?
A.        At least one of the shipments sent to Truax Construction last week was specially ordered.
B.        At least one of last week’s specially ordered shipments did not consist of building supplies.
C.        At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
D.        At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
E.        At least one of the shipments sent to Truax Construction last week was sent out before Friday.
Time: 3’16
归纳总结
Thursday: 5 so; Friday: 全是bs; 周末不上班; 4 shipments到TC, 3个bs,1个不是
错选了D,因为看到说周五只法bs,认为只有周五才发，但是题目中并没有说只有周五才发，而是说周五那一天只发bs,没有说在其他几天不能发，有可能那3个bs都在周一到周四发送的；其中的一个非bs的肯定是在周五前发的，只能明确证明E是对的。

























2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.
The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?
A.        The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years. （这个就说明了这个方案的副作用，到最后并不能实现他们的目标）
B.        Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously. （这边主要说到是上瘾的烟民）
C.        The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years. （吸烟数量增加了得病率应该变高）
D.        The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years. （在说戒烟的人还是无法说明该方案的副作用）
E.        The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years. （时间对比，无关比较）
Time: 1’47
P: 减少抽烟引起的病减少平均的尼古丁量
C: 上瘾的烟民只会抽更多烟
Logic: 减少尼古丁含量只会让烟民买更多的烟去抽从而不会导致抽烟引起的疾病下降

It is a finding that the argument seeks to explain. 黑体句并不是一个发现，而是文章的结论
It provides evidence in support of the main conclusion of the argument.黑体句是结论本身
时间：39’  答案：a
黑体句前面有个转折词yet，而黑体句后又有in the past ten years，可推断此后跟的一定是某种事实或现象，那么黑体句便是本文的结论所在
2-2 Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo dose not have the same financial incentive to adopt such a policy, because __a____.
early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life 早期的诊治并不能完全消除晚期得病的可能性，就是说晚期仍旧可能得病。
the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol 鼓励不鼓励人们是一回事，而人们究竟能不能得这种病是另一回事
RenCo has significantly more employees than Garnet has r与g的员工人数比较没有意义
RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees
r的员工不可能有比g员工更高的c水平这与本体无关
the average length of time an employee stays with RenCo is less than it is with Garnet 无关
时间：2’52 答案：a
逻辑链：gr两个公司都为职工提供医疗服务。g为员工的测试以及手术付费，因此可以省钱，因为这种病如果一直不治后期费用高昂。而r没有同样的动机去实行这样的政策，问原因。
2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.  Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
The effect noted in the studies is not limited to patrons who have credit cards. 无关
Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.有还款压力的人看到logo往往会给的更少比起没有logo，这个起不到支持作用
In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.在研究的所有案例中，用现金付款的客人都是没有信用卡的，一定程度上驳斥了心理学家的假设
In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card. 支持了假设，用现金付款的看到logo会给更多消费，而用信用卡的看不见logo
The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.在文中讲的是用现金支付账单的客人们，并没有涉及用信用卡支付账单
时间：2’27  答案：d
逻辑链：前提：研究显示用现金支付账单的客人当看到账单上的信用卡logo时往往会给更多的小费。
结论：心理学家因此假设信用卡logo提醒了有信用卡的消费者们自己有更强大的购买力，因此使他们愿意付更多。
2-4 Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
In the economist’s argument, the two boldfacedportions play which of the following roles?
The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.一二句方向应该是一致的
The first states the conclusion of the economist’s argument; the second supports that conclusion.由分析得知一二句应该是环境学家的一些看法
The first supports the environmentalists’ conclusion; the second states that conclusion.正确
The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument.第二句是环境学家的结论
Each supports the conclusion of the economist’s argument.这两句和经济学家的看法是相反的
时间：2’4  答案：c
逻辑链：第二句前面有个thus，conclude，说明第二句是个结论，而紧接着后面有however，这些环境学家是错的，那么可以推断一二句都是环境学家的一些看法和结论，而这些被经济学家否定了
2-5 (Weaken题变体) Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.
Criticism:  For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.
Which of the following, if true, provides the best basis for a rebuttal of the criticism?
Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.文章重点在于省水新园林与老园林的取舍，此项为无关信息
A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.此处片面说明了传统园林在肥料和除草剂的开销上大于新园林，但是也有可能存在别的开销比新园林小的多
A significant proportion of the residents of the city live in buildings that do not have yards.很多人家没有院子属于无关信息
It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping. 花在省水风景上的钱不会比花在传统的更多，有效地驳斥了批判者所说
Some homeowners use more water to maintain their yards than they use for all other purposes combined.无关信息
时间：1’27   答案：d
逻辑链：批判者认为转化为新的省水园林所省下来的水费少于20美元，只是很少的一部分，不能覆盖新的园林的费用，问削弱
2-6 Which of following most logically completes the argument?
The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back.  Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______.
some prehistoric cave paintings in France also depict other animals as having a hump 无关
fossils of the giant deer are much more common in Ireland than in France 无关
animal humps are composed of fatty tissue, which dose not fossilize 正确
the cave paintings of the giant deer were painted well before 16,000 years ago 无关
only one currently existing species of deer has any anatomical feature that even remotely resembles a hump 无关

2-7 Shipping Clerk:  The five specially ordered shipments sent out last week were sent out on Thursday.  Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.
If the shipping clerk’s statements are true, which of the following must also be true?
At least one of the shipments sent to Truax Construction last week was specially ordered.未知信息
At least one of last week’s specially ordered shipments did not consist of building supplies.也可能全部包含，毕竟前面还有周一周二呢
At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.周四的船里没说运的是啥，就有可能四个都是周四出发的
At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.周五装的都是建筑材料，也可能送去其他地方了
At least one of the shipments sent to Truax Construction last week was sent out before Friday.
时间： 2‘45   答案：e
逻辑链：有五艘特殊的船在上周四出发，而周五出发的所有的船上装运的都是建筑材料。被送去tc的四艘船中只有三艘是装运建筑材料的➡️那么剩下的一艘肯定不是周五出发的

2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.
The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?
The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.正确
Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously. 没上瘾的人是否会吸更多的烟无从考证
The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years. 得吸烟相关疾病的人数在未来五年会减少并不能从原文中得到支持
The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years. 原文并不能支持此项
The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.  未来五年和过去五年没法比较
时间：2‘14  答案：a
逻辑链：为了减少吸烟相关的疾病，s处执法者计划在未来五年减少一半的香烟中尼古丁的含量，然而这会导致已经上瘾的人吸更多数量的烟。
2-9 Newspaper editorial:
In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.正确
Former inmates are no more likely to commit crimes than are members of the general population. 罪犯与正常人没法比较
The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released. 取非不能驳斥，错
Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does. 高中课程与大学课程属于无关信息
The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.  无关
时间： 2‘23   答案：a
逻辑链：为了减少犯罪率，长官对罪犯严厉且使监狱环境更恶劣，也不让犯人们上课，然而这违背了长官们的初衷，因为上课的犯人们被释放后的犯罪率比不上课的人低得多
2-10 Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.
Scott:  The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler’s decline.
Which of the following, if true, most seriously calls Scott’s hypothesis into question?

The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining. 不吃sb的另外一种鸟，他和w一样依赖于咖啡园，也减少了，说明这种减少与sb无关
The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers. 还是在说sb减少
The drop in the population of the spruce budworm is expected to be only temporary. 无关
Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations. 无关
Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.  无关

时间：2’40  答案：a
逻辑链：k说w每年秋天都会迁徙到南美洲的咖啡园，所以w的减少跟咖啡园树密度减少有关
s认为猎物sb的减少可以解释w的减少，因为w是吃sb的
