The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.

Which of the following, if true, provides the most support for the researchers' hypothesis?

正确答案: B

2.13 败! 附部分JJ

感谢CD,JJ已经比较全了,可惜我没有把握好,M51 V29 680

我按倒叙给jj,先上Verbal

1 GWD原文:
 Companies that must determine well in advance of the selling season how many units of a new product to manufacture often underproduce products that sell well and have overstocks of others. The increased incidence in recent years of mismatches between production and demand seems ironic, since point-of-sale scanners have improved data on consumers’ buying patterns and since flexible manufacturing has enabled companies to 24 produce, cost-effectively, small quantities of goods. This type of manufacturing has greatly increased the number of new products introduced annually in the United States. However, frequent introductions of new products have two problematic side effects.

For one, they reduce the average lifetime of products; more of them are neither at the beginning of their life (when prediction is difficult) or at the end of their life (when keeping inventory is expensive because the products will soon become obsolete). For another, as new products proliferate, demand is divided among a growing number of stock-keeping units (SKU’s). Even though manufacturers and retailers can forecast aggregate demand with some certainty, forecasting accurately how that demand will be distributed among the many SKU’s they sell is difficult.  For example, a company may be able to estimate accurately the aggregate number of shoes it will sell, but it may be uncertain about which specific types of shoes will sell more than other types.

题目一样,都是三道,只是顺序好像不同,我考前准备到了,按照答案答的。

Q23:
Which of the following most accurately describes the function of the last sentence in the passage (lines 35-40)?

   1. To cite a situation in which the aggregate demand is more important than the distribution of demand among SKU’s
   2. To refute an assertion about the side effects of flexible manufacturing
   3. To illustrate an assertion about companies’ ability to forecast demand
   4. To provide an example of ways in which companies address the difficulties of forecasting demand
   5. To note an exception to the author’s assertion about distributing demand among SKU’s

这道题我的GWD答案里给的是D,刚看了JJ整理,给的是C,现在也觉得C好些,真是晕死!

2 超市货品摆放那篇;JJ详细;
补充个细节题:超市减少货品数量,应当怎么处理空出来的位置
我选,摆放(还放在货架上的)同样的货品,增加客户注意到自己喜欢物品的可能性;


3 美国苹果商
文章长。我记得好像3段,但只记得两段内容了:

1P 说从1890 到1930年(年数有可能不对)苹果的交易发生方式发生变化了,一开始,果农在全美都有,和buyer是面对面的, 到这段时间的末期,加州的苹果商变得很强大,苹果都是加州生产,然后贩卖到各州。苹果商变得强大后,由于什么原因,出了个什么Act(对这个act的产生原因有细节题),使果农不受antitrust法控制。

2P 苹果的质量变得不好。如果顾客发现苹果质量不好,果农和分销商都有责任;可能苹果质量本身不好,也可能是运输中损坏了苹果。这样就有人钻这个空子(卖质量不好的苹果),然后扯皮,贿赂官员。

4 爱尔兰妇女历史研究

两段,最后一篇时间紧,感觉做的不好,不误导大家了。
内容基本是,研究爱尔兰女性历史的学者仿照研究britain历史的学者,研究妇女选举权等等,其实这些研究方法有问题。

CR,
1 先贡献一道GWD原题;

The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.
Which of the following, if true, provides the most support for the researchers’ hypothesis?
A. Even after long periods of sleep when adenosine is at its lowest concentration in the brain, the number of brain cells bound with adenosine remains very large.
B. Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to sites on brain cells.
C. Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body.
D. Some areas of the brain that are relatively inactive nonetheless release some adenosine.
E. Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are high.

2 某个地方医生和病人的比例是1:6,希望将此比例提高到1:5,但是本地已没有多余的医生了,因此,临近的地方的医生会到这里工作。问削弱:

迷惑选项:临近的地方也缺医生;
我选:医院可以通过减少病人住院的时间将比例提高到1:5

1 遇到了关于content那个词用法,注意content即可以作动词,又可做形容词,注意相应的搭配;
2 考了unlike, as等对比,但是并不容易,因为里面有生词,让你搞不清比较的对象是一种人还是一个地方,唉,知道需要平行也没用。


Math:
1 补充一个:
H同学的red球比B同学的blue球重17%,H同学的red球数量比G同学blue球的数量少10%,问一个红球比一个蓝色球重多少
1.17/0.9 - 1 = 0.3 答案30%

2 简单题
np<6?
1)n<2
2)p<3
选E

AI: 要获得lasting success需要遵循传统的方法

Math JJ的数量已经够了,研究明白基本就是51了,我还提前了5分钟end了;非常感谢JJ提供和整理的人!!!没有JJ的话,我肯定没有51的。
语文部分,有一半的SC的考点是清晰的,和老的Prep破解是一个路子;另一半感觉有些怪,有的是有生词,变得不好把握句意;有的在理解句子逻辑意思的时候,感觉不同选项有不同的理解,但是不能确定哪个更优(还是逻辑意思没理解透)。逻辑感觉还好,和GWD, prep路数一致。这次感觉死在阅读上,虽然有机经,只能增加背景知识和辅助理解,做题的时候还要自己认真分析。

总之,遇到了不少JJ,但是还没有达到理想的成绩,很遗憾。
