1. 政府应行使其职权颁布法律禁止在火车上销售以及饮酒、同样吸烟在公共交通工具上也应受到明令禁止。。。因此。。。作者认为。。。
好吧我总是虎头蛇尾==+  45s
2. 要做仿造大理石就得有灵巧的手？然而毕加索木有这个先决条件，却也可以制作仿大理石。40s
3. 90%的人觉得自己已经足够了解保健的重要性。然而调查显示实际上只有20%了解DNA的概念。因此推论至少80%的人不知道公共健康政策的时效意义。45s
4. 灰松鼠在大森林里威胁到了一种猫头鹰的生存。因为松鼠总是蹦来蹦去的，总是把树枝压断，猫头鹰筑巢的地方就受到威胁了。（他们是在卖萌么==+）有人提议说要放毒药把灰松鼠毒死以控制其数量保护猫头鹰，但是这样做起不到保护猫头鹰的效果，因为毒药总是放在容器里面，只有松鼠和某些其他动物能接触到。（自己最后的逻辑在哪里看不粗来） 39s
5. 经理说我们餐厅去年的销售量比去年整体提升，说明顾客很喜欢咱们的美食呀~
会计说，如果您单个分析咱们公司的每一家餐厅，其实是有所下降的。。。。45s木有读完 最关键的部分没找出来，待我先发了再仔细揣摩一遍。阅读速度是硬伤呜呜呜呜

1. 56" 超时了
Background：When intoxicated riders get off the train, get in their cars, and drive, the public is exposed to at least as much danger as are nonsmoking rail passengers who are forced to inhale cigarette smoke.
Premise: the state passed a law to protect the health of commuters by prohibiting smoking on the commuter line.
Conclusion: alcohol consumption on commuter trains should be banned.
Assumption: alcohol would cause the public in danger as same as the cigarette smoke.

2. 30"
Background：Creating false marble can excel only by a light hand.
Premise：Picasso was a great artist.
Conclusion：While he did not have a light hand he could have excelled at creating false marble.
Flaw:  Great artist are not different

3. 20"
Background: 90 percent of the population believes itself to be well informed about health care
Premise: only 20 percent knows enough about DNA.
Conclusion: At least 80 percent of the population does not know enough about medical concepts
Flaw:  well informed about health care= knows enough about DNA

4. 25"
Background：The gray squirrel threatens the indigenous population of an endangered owl species.
Premise：Some local officials have advocated setting out poison for the gray squirrels.since the poison would be placed in containers accessible only to squirrels and other rodents.
Conclusion：The poison would pose no threat to the owl population
Flaw: The poison will affect the trees and cause them died eventually.

5. 25"

Conclusion：The desirability of our meals to consumers has clearly decreased, given that this group of restaurants.
Explanation：每个餐厅减少，但是总数meals增加 means餐厅数量增加

几年前的还是来凑下热闹，记录成长点滴。练练LAST和别的可能有进步呢。

1.P：火车禁止销售酒。最近州法律禁止在车子上吸烟保护乘客。当喝醉的乘客下火车，上车子开车，周围的人和不吸烟的乘客一样被迫吸烟，受到危险。
分析：最近禁止火车吸烟，因为吸烟的人下火车开车的时候，周围的人和火车上不吸烟的人一样都会吸二手烟。结论是火车要禁止销售酒。
【因果】因为不吸烟和public受到二手烟威胁所以禁止吸烟。结论禁止喝酒。应该是个类比。
问假设。应该就是吸烟和喝酒可以类比。喝酒和吸烟一样，当喝酒的人下车的时候，对周围的人和不喝酒的人也产生一样的危害。

2. P：只有那些有Light hand的人才可以创造错误的marble。毕加索，伟大的艺术家，所以当他没有light hand 的时候，也可以create false marble.
分析：原文说只有light hand---false marble. 接着后面反驳，毕加索没有light hand，但是create false marble, 并且是great artist。应该是反对前提的逻辑错误。前面说必须light hand，后面反对说没有Light hand也行。
原文A---B, 后面 NO A---B。矛盾前提。

3。30’ 百分之90的人认为知道保护身体，20的人了解DNA，所以80的人不知道…削弱：默认20知道DNA的人就知道make policy decision，所以得出80的结论，但是可能20的人只是know DNA, but not personal choices or decisions.

4.46’  还是GMAT比LAST容易了。
松鼠威胁O，因为松鼠---树皮—O鸟巢。所以准备毒药松鼠，因为O和其他鸟类不会碰到，所以可以。问削弱。目的方案。目的拯救O，方案毒药松鼠。削弱：目的达不到，毒药可能因为什么原因会导致O减少，比如O的食物…会受到毒药影响，O 受到影响。

5.1min  观点1：去年销量高于前年，是因为消费者喜欢。观点2：去年和前年每一家店铺销量都减少，顾客desirability下降，所以趋势是销量变小。
1去年desirable上升。2反驳desirability减少了。
归纳：12相反。
削弱2：反驳desirable下降，不是因为desirability下降导致sale降低，二是他因。比如desirability不变或者更高，是因为经济，食物水平等其他原因导致sale下降。【因果】因为desirability降低---sale降低。因果经典削弱四个方向。

NO. 1

The government should enact a bill that would prohibit the sale and consumption of alcohol on commuter trains. Recently, the state, exercising its legitimate authority, passed a law to protect the health of commuters by prohibiting smoking on the commuter line. When intoxicated riders get off the train, get in their cars, and drive, the public is exposed to at least as much danger as are nonsmoking rail passengers who are forced to inhale cigarette smoke.
In arguing that alcohol consumption on commuter trains should be banned, the author relies on

60’略有超时，而且没太看懂那个比较的关键点
P:应该有法律禁止在commuter line里面买和喝酒
P：有一些地方禁止在train上抽烟→为了protect the health of public。一些intoxicated人下了train上了car drive，public至少会和被迫要吸入二手烟的人一样？（关键！intoxicated是喝醉的人的意思！！当喝醉的司机下了train，上了车，并且开车，公众的危险不会比被迫吸二手烟的要少）
C：所以应该有这样的规定，禁止喝酒。

P：P是一个excellent的艺术家，没有light hand，但是他可以创造出假的M。
妈妈咪啊，C和P竟然都搞错了QAQ，阅读的时候一定一定一定要注意逻辑词！！！
P：P是个great艺术家
C：所以即使他没有light hand也能创造出excellent FM


NO.3

Although 90 percent of the population believes itself to be well informed about health care, only 20 percent knows enough about DNA. So apparently at least 80 percent of the population does not know enough about medical concepts to make well-informed personal medical choices or to make good public policy decisions about health care.
The argument’s reasoning is questionable because the argument fails to demonstrate that

P：虽然90%的人都认为他们well-informed about their health condition，but only20% know enough about DNA
C：so，at least 80%人没有（does not know enough about）medical concept→make well-informed medical decision
Or to make good public policy decision about health care

NO.4

The gray squirrel, introduced into local woodlands ten years ago, threatens the indigenous population of an endangered owl species, because the squirrels’ habitual stripping of tree bark destroys the trees in which the owls nest. Some local officials have advocated setting out poison for the gray squirrels. The officials argue that this measure, while eliminating the squirrels, would pose no threat to the owl population, since the poison would be placed in containers accessible only to squirrels and other rodents.
Which one of the following, if true, most calls into question the officials’ argument?

45’
P：gray松鼠十年前被引入森林→threaten the endangered in?? （本地的）owl→松鼠破坏owl栖息的树的树皮
P：政府投毒杀死松鼠
C：能杀害松鼠但是不会伤害到owl，因为毒药只放在松鼠和别的rodent可以接近的地方

NO.5

Sales manager: Last year the total number of meals sold in our company restaurants was much higher than it was the year before. Obviously consumers find our meals desirable.
Accountant: If you look at individual restaurants, however, you find that the number of meals sold actually decreased substantially at every one of our restaurants that was in operation both last year and the year before. The desirability of our meals to consumers has clearly decreased, given that this group of restaurants---the only ones for which we have sales figures that permit a comparison between last year and the year before---demonstrates a trend toward fewer sales.
If the sales figures cited by the accountant and the sales manager are both accurate, which one of the following must be true?
Which one of the following, if true, most seriously calls into question the accountant’s argument?

75’
Sales Managers：P：去年我们公司所有餐厅的meal sale比前年要高很多。C：人们发现我们的食物desirable。
Accountant：p：总的来看是的，但是如果你看每一家餐厅会发现去年和前年sale meal的数量急剧下降了。C:以这个数据（这些餐厅来看——我们仅有数据的餐厅——以此可以用来做前年和去年sale量的比较）来看，我们的sale数量是下降的，意味着人们对我们餐厅的 desirable也是下降的。
