不好意思 daisy迟到了 haha 今天开始走到系列2了。最勤奋的bat,糊糊,bala和纳丁有什么感受呢。




1. In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then.  Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales.  That claim is false, however, since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.


Which of the following, if true, most strongly supports the argument against Moviemania’s claim?
--GWD3-14


Key: Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.


2.
Which of the following most logically completes the argument below?
Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville.  The downtown shopping district has lost business at this rate before and has always completely rebounded.  Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because __________.
--08prep 77


Key:the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores , on whose ability to draw shoppers many of the other downtown stores depend
3.
Columnist: A democratic society cannot exist unless its citizens have established strong bonds of mutual trust. Such bonds are formed and strengthened only by participation in civic organizations, political parties, and other groups outside the family. It is obvious then that widespread reliance on movies and electronic media for entertainment has an inherently corrosive effect on democracy.


Which one of the following is an assumption on which the columnist’s argument depends?
--LSAT
Key: Relying on movies and electronic media for entertainment generally makes people less likely to participate in groups outside their families.


4. Medical researcher: As expected, records covering the last four years of ten major hospitals indicate that babies born prematurely were more likely to have low birth weights and to suffer from health problems than were babies not born prematurely. These records also indicate that mothers who had received adequate prenatal care were less likely to have low birth weight babies than were mothers who had received inadequate prenatal care. Adequate prenatal care, therefore, significantly decreases the risk of low birth weight babies.
Which one of the following, if true, most weakens the medical researcher’s argument?
--LSAT
Key: Mothers giving birth prematurely are routinely classified by hospitals as having received inadequate prenatal care when the record of that care is not available.


5. Unlike newspapers in the old days, today’s newspapers and televised news programs are full of stories about murders and assaults in our city. One can only conclude from this change that 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.
Which one of the following, if true, would cast the most serious doubt on the conclusion?
--LSAT
Key: Newspapers and televised news programs have more comprehensive coverage of violent crime than newspapers did in the old days.

Answer: 这次和上次不一样。。。

3. 35s

1.【26s】M电影院去年把做爆米花的椰子油换成了更加健康的椰子油--》但是今年，M决定换回来，因为他们说换椰子油的做法影响了他们的销量，。--》这种那个说法是不正确的，因为看M的销售记录，发现今年比去年的销量提升了。
 Support：爆米花的提升幅度大于来电影院看电影人的提升幅度。
2.【45s】百分之20的商家在M地区将会由于新的打折商店的营业纷纷倒闭。——》以前也出现过如此速率的倒闭，但是最后这些商家还是重振旗鼓--但是这次倒闭的商家还会重振旗鼓的想法是不正确的，因为：上次的倒闭是由于经济危机，经济复苏后就好转了，但是这次不同———》他因。
3.【39s】一个民主的社会 ，它的国民必须要有相互信任感——》只有参加一些政治组织等什活动的人才会有这种信任感——》所以，当今社会各种电子娱乐活动严重影响到了一个国家的民主。
AS：搭桥：严重的依赖各种电子娱乐活动会导致人们不愿去去参加这些组织的活动。
4.【56s】研究发现：早产儿比非早产儿会有更低的体重和健康问题--》收收到精心照料的孕妇要比受到精心照料的孕妇生下的孩子体重轻--》所以孕妇的产前照顾是十分重要的。
weaken：受到精心照料的孕妇往往容易早产。
5，【30s】不像过去时候的报纸，现在的报纸充满了各种犯罪和侮辱的报道——》所以从中可以得出，现在的暴力犯罪已经难以控制了--》为了防止人生的伤害，我们最好呆在家里不要出来。（好二的结论）
weaken：以前的报纸对这种暴力新闻有控管，现在没有。

Unlike newspapers in the old days, today’s newspapers and televised news programs are full of stories about murders and assaults in our city.
