1.premise: today’s newspapers and televised news programs are full of stories about murders and assaults in our city
conclusion: violent crime is now out of control, and, to be safe from personal attack, one should not leave one’s home except for absolute necessities
Q:weaken
prephrase: newspapers and televised news purposely report something dangerous and repeat some cases over and over again,thus actually violent cases appear not as frequently as  the news reported.
(A)Newspapers and televised news programs have
more comprehensive coverage of violent
crime than newspapers did in the old days.---correct,since it gives another factors that leads to the high violent news,namely the more comprehensive converge. so we can infer that the increased violent news are not attributed to the violent crimes themselves.
(B) National data show that violent crime is out of
control everywhere, not just in the author’s
city.----opposite ,this statement strengthen the conclusion that we should not go out of home
(C) Police records show that people experience
more violent crimes in their own
neighborhoods than they do outside their
neighborhoods.------irrelevant,since wherever the more violent crimes happen, it is dangerous to get out of home,thus this statement is slightly strengthen.
(D) Murder comprised a larger proportion of
violent crimes in the old days than it does
today.------irrelevant, what kind of violent crimes is irrelevant to the point.注意这里是相对数与绝对数的比较,murder is a proportion of violent crimes,so if we don't know what proportion of murder occupies the total violent crimes,the statement is unclear.
(E) News magazines play a more important role
today in informing the public about crime
than they did in the old days.---我原本以为new magazines play a more important role表示数据可能不真实,可能反复播出故意引起人们注意。文章中并没有提这方面的信息,所以不知道more informing代表着什么,因此是irrelevant 注意!不要自己过度推理要基于原文的信息

1.
Time:33s
P:unlike newspapers in the old day, today's newspaper and televised news programs are full of stories about murders and assauts.
C: violent crime is now out of control, and, to be safe from personal attack, one should not leave one’s home except for absolute necessities.
Pre:削弱 报道量变多只能说明现在报道的比以前多,不代表犯罪量就真的变多了
(A) Newspapers and televised news programs have
more comprehensive coverage of violent
crime than newspapers did in the old days. 正解
(B) National data show that violent crime is out of
control everywhere, not just in the author’s
city.
(C) Police records show that people experience
more violent crimes in their own
neighborhoods than they do outside their
neighborhoods.
(D) Murder comprised a larger proportion of
violent crimes in the old days than it does
today.
(E) News magazines play a more important role
today in informing the public about crime
than they did in the old days.注意该选项 说magazine的地位问题,不能直接反应是不是报道数量比以前多了

2. 1:00 D 不是特别清晰 只是觉得D指出了城市与乡村的差别 A选项没有体现两者的差别。
3. 50s C
4. 48s E
5. 41s D A为什么不行? 。。。正确答案是A。。。 那D为什么不行。。。 这么去理解,profits要double 首先你per plant的产量下降,即使你per acre的plants数量double了,你总产量还是没有double的,那么不能解释profits double这一现象。 A就可以解释,因为cost变少了 一定要注意这个数量关系。

crime is now out of control, and, to be safe from

推测:新闻报道的多和实际多还是有很大差距的

crime than newspapers did in the old days. 无关

1.    (24021-!-item-!-188;#058&000691)
On Pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but populations of the two species are more stable in rural areas far from human settlement.  The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.
逻辑链:在太平洋的岛上,HG替代了原有的MG在城市地带;但是在乡村地区则没有太大变化。HG不攻击MG,但是会组织MG吃一堆虫子
推测:城市只有一堆虫子,要吃的时候老是被阻止然后就死完了。。。

Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas?


(A) In urban areas, geckos are valued because they eat so many insects. 新消息
(B) Geckos defend territories against other members of the same species.  新消息
(C) House geckos that arrive on islands are carried there in boats and planes. 新消息
(D) In places where there are lighted buildings, insects tend to gather around the light. 正确

2.    (24069-!-item-!-188;#058&000703)
Downtown Villieu was once a flourishing business district, but most Villieu-area businesses are now located only in the suburbs.  The office buildings downtown lack the modern amenities most business operators demand today.  To lure more businesses downtown, Villieu officials plan to have several modern office buildings constructed and to offer reduced local tax rates to any business that leases space in a new downtown building.
逻辑链:DV原来是商业中心,但是现在商业区挪到了郊区。市中心的办公区缺乏如今很多商业活动需要的设施。为了吸引公司到市中心,官员计划建设更多的现代化办公楼,并为那些在市中心租房的公司提供更低的税率
推测:方案题达不到目的一个是可能没人响应,一个是有不良后果
Which of the following, if true, most threatens the plan's likelihood of success?
(A) Most of the businesses currently located in downtown Villieu have long-term leases on the space they occupy there. 无关
(B) The existing office buildings in downtown Villieu have, on average, a much higher vacancy rate than do office buildings in Villieu's suburbs. 无关
(C) The local tax rates in Villieu's suburbs are significantly lower than downtown Villieu's proposed rate for businesses that lease space in the new office buildings. 正确
(D) Most of the businesses that currently lease office space in downtown Villieu also lease office space in Villieu's suburbs. 无关
(E) With the new office buildings, downtown Villieu would have a greater amount of modern office space than any other downtown business district in the region. 可能加强


3.    (24117-!-item-!-188;#058&000708)
Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested.  Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient.  The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.
逻辑:NA每天有很多航班,然后highly congested。NA的成功基于经济和quick turnaround,他计划用S替换大飞机。S燃油效率高,使得油费下降而且减少了时间
推测:反正就是讲S不好

Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?


(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. 加强
(B) Aviation fuel is projected to decline in price over the next several years. 无关
(C) The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs. 前加强 后无关
(D) None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses. 无关
(E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs. 正确


4.    (24257-!-item-!-188;#058&001200)
Which of the following most logically completes the argument?
A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches.  Corn planted this closely will produce lower yields per plant.  Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.
逻辑:新机器可以使农作物种植距离减少一半,但是种的这么近农作物会减产。尽管如此,新机器还是会使农民受益加倍
推测:种的多或者是有其他好处,可以是C减少或是r增加
P=r-c

(A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation 虽然支持了结论 但是没有讲到倍数的问题
(B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants 长得高和profit关系还是蛮远的
(C) with the larger number of plants growing per acre, more fertilizer will be required 削弱
(D) with the spacing between rows cut by half, the number of plants grown per acre will almost double 正确 主要是结论里面还有倍数
(E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted 无关
