22. GWD27-Q22:

Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago.  Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water.  Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.

Which of the following is most strongly supported by the information given?

A.      Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean.

原文说whales在五百万年前才开始有kidney，而在之前不可能长时间在salt water里面。A选项说whales的化石不可能出现在被广阔海洋隔离的另一块大路上。因为他们没有长时间生活在salt water里面的能力，所以他们不可能穿越海洋。这样分析对吗？

B.       Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.

C.      Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.

D.      The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.

E.       Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.

Q22:  

The sense of delayed gratification, of working now for later pleasure, has helped shape the economic behavior of our society. However, that sense is no longer nurtured as consistently in our children as it once was. For example, it used to take a bit of patience to put together the toys that children got in cereal boxes; now the toys come from the boxes whole.  

Which of the following is an assumption of the passage above?  

A.      The toys in cereal boxes have changed partly because the economic conditions of our society have improved.

B.       The influence of promotion gimmicks on the economic behavior of our society has increased over the years.  

C.      The toys that used to come in cereal boxes were put together by the same children who played with them.  

原文说现在买来的玩具都是拼装好的，就不会让孩子有耐心先拼装，再享受乐趣，说明现在延迟满足的情况不像过去了。C选项说过去买来的玩具，拼装和享受玩的乐趣必须是同一个孩子。因为如果要不是同一个孩子，那个玩玩具的孩子只是玩，玩之前并没有耐心的等待，也就没有做到延迟满足。这样分析对吗？



D.      Part of the pleasure of any toy lie in putting the toy together before playing with it.  

E.       Today's children do not expect a single toy to provide pleasure for a long period of time.

Q3: TTGWD11-Q19:

In Rubaria, excellent health care is available to virtually the entire population, whereas very few people in Terland receive adequate medical care. Yet, although the death rate for most diseases is higher in Terland than in Rubaria, the percentage of the male population that dies from prostate cancer is significantly higher in Rubaria than in Terland.

Which of the following, if true, most helps to explain the disparity between the prostate cancer death rate in Rubaria and Terland?

A.      Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland.

B.       Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.

知道其他选项都不对，但是B选项为什么就能解释这种disparity那？逻辑思路是什么？

C.      Being in poor general health does not increase one’s risk of developing prostate cancer.

D.      It is possible to decrease one’s risk of getting prostate cancer by eating certain kinds of foods, and such foods are more readily available in Rubaria than in Terland.

E.       Among men in Rubaria, the death rate from prostate cancer is significantly higher for those who do not take full advantage of Rubaria’s health care system than for those who do.

Q32: TTGWD2-Q28:

Fearing competition from stores that rent video games for home use, owners of stores that sell video games lobbied for protective legislation.  Citing as a precedent legislation that postpones home film rentals until one year after general release to theaters, the video sellers proposed as an equitable solution a plan that would postpone rental of any video game until it had been available for sale for one year.

Which of the following, if true, would support an objection by owners of video rental stores that the fairness of the proposed legislation is not supported by the precedent cited?

这道题的问题就没看明白，麻烦哪位同学给翻一下，然后把解题思路讲一下，谢谢了

A.      Although the daily rental fee for home use of films is generally the same as that for video games, the average rental period for a video game is longer than that for a film.

B.       Film rentals for home use tend to particularly strong during the first year after a film has been made available for both sale and rental at video rental stores.

C.      Most people are interested in playing only the latest video games and tend to find video games that have been available for over a year unappealing whether they have played them before or not, whereas films maintain their appeal far longer after their release.

D.      People who rent video games tend to play them by themselves, whereas people who rent films invite friends and neighbors to watch.

E.       A slight decline in revenues from films that have been recently released in theaters has been attributed to the growing market for rentals of films for home use.

Q36: TTGWD4-Q7:  这题从In the five years since the opening of Colson’s以后就完全没明白

Although the discount stores in Goreville’s central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long.  In the five years since the opening of Colson’s, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson’s.

Which of the following, if true, most seriously weakens the argument?

A.      Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened.  

B.       Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.

C.      At present, the central shopping district has as many stores operating in it as it ever had.

D.      Over the course of the next five years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades.

E.       Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.

先来第一题：

Although fossil evidence shows that some early whalespecies that lacked such kidneys sometimes swam in the Earth’s saltwateroceans, these species must have had to return frequently tofreshwater rivers to drink.（只喝淡水的鲸鱼可以到海里，但是要回去淡水里喝水，所以就不可以在海里呆太久。）


A. Fossils of whale species dating from between sixtymillion and fifty million years ago will notbe found on continents that were at the time separated from ancient Asia by wide expanses of ocean.（fossils在这个时间段内不可能出现在其他和Asia被ocean阻隔了的continents上。因为这个时间段内，whales还没有长出kidneys，根本不可能靠海水生活，即使有evidence发现有一些可以在saltwater oceans里游泳，但还是会经常返回淡水里喝水，这就说明了在Asia起源的whales是不可能出现在和Asia之间有ocean阻隔了的continents上。）

cancer那题好像是说  T的所有死去的人中 许多的了癌症的都是老一些的人（就是得癌症可能死于岁数大 而不是死于癌症） 因此 比例就小了
而C选项，我开始也诧异。 开始时这么想的：T得重病的多，反而死于癌症的百分比少。 （我先想到的是得重病的人里癌占少数) .可是答案没有，就发现C说破的健康状态不引发得癌的。 貌似很贴近我的设想。 但是还是没有进一步的说 得癌的少。（C只是提供 存在得癌少额可能） 我目前是这么理解的
