标题: 大家帮帮忙啊马上就考了几道诡异的GWD

其实这些题我好象都做过的但是不知道为什么思路就是没有了烦躁

1. GWD-27-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?

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.
Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.
Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.
The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.
Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.

能不能问下A说的是什么啊我很清楚的知道其他的不对就是没看出来A哪对

1. GWD-26-Q31

Which of the following most logically completes the argument??

When people engage in activities that help others ,their brain releases endorphins,

the brain’s natural opiates, which induce in people a feeling of well-being. It has

been suggested that regular release of endorphins increases people’s longevity.

And a statistic on adults who regularly engage in volunteer work helping others

shows that they live longer, on average, than adults who do not volunteer. How-

ever, that statistic would be what we would expect even if volunteering does not

boost longevity, because .

A. in the communities studied, women were much more likely to do regular

volunteer work than men were, and women tend to live longer than men do.

B. the number of young adults who do regular volunteer work is on the increase

C. the feelings of well-being induced by endorphins can, at least for a time, mask

the symptoms of various conditions and diseases, provided the symptoms are

mild.

D. it is rare for a person to keep up a regular schedule of volunteer work through-

out his or her life.

E. Some people find that keeping a commitment to do regular volunteer work

becomes a source of stress in their lives.
