OG12的83，93，104讨论一下

83，Journalist:In physics journals,the number of articles reporting the results of experimentsi nvolving particle
accelerators was lower last year than it had been in previous years.Several of the particle accelerators at major research institutions were out of service the year before last for repairs,so it is likely that the low number of articles was due to the decline inavailability of particle accelerators.

Which of the following,if true,most seriously undermines the journalist's argument?

(A)Every article based on experiments with particle accelerators that was submitted for publication last year
actually was published.
(B)The average time  scientists must wait for access to aparticle accelerato rhas declined over the last
several years.
(C) The number of physics journals was the samelast year as in previous years.
(D) Particle accelerators can be used for more thanone group of experiments in any given year.
(ERecent changes in the editorial policies ofseveral physics journals have decreased thelikelihood that articles concerning particle acceleratorresearch will be accepted for publication.E

Ｅ　明明说去年的事，这里却是一个ｒｅｃｅｎｔ
Ｄ　我觉得就是说availability　of particle accelerators　并没有减少

９３Commentator: The theory of trade retaliation statesthat countries closed out of any of another country’smarkets should close some of their own markets tothe other country in order to pressure the othercountry to reopen its markets. If every country actedaccording to this theory, no country would trade withany other.
The commentator’s argument relies on which of thefollowing assumptions?

(A) No country actually acts according to the theoryof trade retaliation.

(B) No country should block any of its markets toforeign trade.

(C) Trade disputes should be settled by internationaltribunal.

(D)For any two countries, at least one has somemarket closed to the other.D

(E) Countries close their markets to foreigners toprotect domestic producers.





不明白为什么选Ｄ
１０４.Although the discount stores in Goreville’s centralshopping district are expected to close within fiveyears as a result of competition from a SpendLessdiscount department store that just opened, thoselocations will not stay vacant for long. In the five yearssince the opening of Colson’s, a nondiscountdepartment store, a new store has opened at thelocation of every store in the shopping district thatclosed because it could not compete with Colson’s.Which of the following, if true, most seriously weakensthe argument?
(A) Many customers of Colson’s are expected to doless shopping there than they did before theSpendLess store opened.
(B) Increasingly, the stores that have opened in thecentral shopping district since Colson’s openedhave been discount stores.B
(C) At present, the central shopping district has asmany stores operating in it as it everhad.
(D) Over the course of the next five years, it isexpected that Goreville’s population will grow ata faster rate than it has for the past severaldecades.
(E) Many stores in the central shopping district selltypes of merchandise that are not available ateither SpendLess or Colson’s.

这个连题干我都没看懂，什么打折不打折的商店阿

自己顶，大家帮帮忙阿

好歹也排好版再发上来吧。
这个样子叫人怎么看？给点诚意好不好。。。。

夏雨霏霏

错了，求问心切，不好意思

夏雨霏霏

大家帮个忙阿

说下我对于83题 D选项的理解

我刚开始和你想的一样，题目说因为机器坏了，使得文章减少。
答案D说，一个机器可以供多组使用，这样的话，就算坏了一台，也可以有其他的机器来用啊。正好起到weaken的作用。

但是再深入分析，如果一台机器可供好几个组使用，那么只要坏掉一台机器，好几个组都不能做实验了，这就影响了实验报告。起到了support的作用了。
只有一台机器或许有点极端的话，就算有3台机器共3个组使用。突然间坏了两台，剩下那一台3个组都要用，多少会影响些结果吧。设施多一些，做起实验来总归便利一些吧。

只是我这个想法和OG的解释有点出路。

不过我总算是把自己说服了。
其他人有什么意见吗，一起来讨论啊。

93.某个理论认为，如果他国某个市场不让我国的产品进入，那么我国就应该以牙还牙。评论：如果所有国家都这么做，国际贸易就不存在了。
d:取反，有两个国家互相友好，互相开放所有市场。评论的结论就不成立了

题目是,G那里的discount店开了会影响周围的店,反驳说不会影响,因为过往5年里开了非discount的店周围的店都活了下来.而B里提出了weaken的条件,因为本来非discount店边上开出来的是discount店,那么如果现在要开的是discount店那么边上再开discount店是活不下来的

83的理论我个人认为是这样的。
逻辑要找weaken，推理链是A：acc坏了几台没有修。B：所以基于acc实验的文章少了。
A推B。要weaken这个结论就反向思维：A推不出B。因为文章数量减少是一个事实，那么不去对事实进行猜测，而是对造成这个事实的原因进行怀疑。（即基于acc实验的文章的减少不是因为acc坏了几台没有及时修，而是其它原因，比如基于acc实验的文章没人写，最近没人做acc实验等。）
D说虽然acc坏了几台没有修，但是acc可以很多个组使用，那么坏了几台，其他的组可以共享一台acc，那么还是一样可以出成果。所以D更像是一个support的结论。比如：acc坏了几台没有修，但是这个月的基于acc实验的论文没有减少。问support，D就是答案。
