[求助]快来看看最新的GWD28－2的阅读阿！（重新编辑过的）

上新东方的时候朱江老师给的GWD题.可惜没有答案，大家帮忙看看，谢谢NNS，尤其是wangyu73cn

28-passage two

Carotenoids, a family of natural pigments, form an 

important art of the colorful signals used by many animals.

 Animals acquire carotenoids either directly (from the plants 

and algae that produce them) or indirectly (by eating insects) 

and store them in a variety of tissues. Studies of several animal 

species have shown that when choosing mates, females prefer males 

with brighter carotenoid-based coloration. Owens and Olson 

hypothesize that the presence of carotenoids, as signaled 

by coloration, would be meaningful in the context of mate 

selection if carotenoids were either rare or required for 

health. The conventional (Line 15) view is that carotenoids

 are meaningful because they are rare: healthier males can 

forage for more of the pigments than can their inferior 

counterparts. Although this may be true, there is growing 

evidence that carotenoids are meaningful also because they 

are required: they are used by the immune system and for 

detoxification processes that are important for 

maintaining health. It may be that males can use 

scarce carotenoids either for immune defense and 

detoxification or for attracting females. Males 

that are more susceptible to disease and parasites 

will have to use their carotenoids to boost their 

immune systems, whereas males that are genetically 

resistant will use fewer carotenoids for fighting 

disease and will advertise this by using the pigments 

for flashy display instead.

28-13: Information in the passage suggests that which of the following is true of carotenoids that a male animal uses for detoxification processes?

A: They were not acquired directly from plants and algae

B: They cannot be replenished through foraging.

C: They cannot be used simultaneously to brighten coloration.

D: They do not affect the animal’s susceptibility to parasites.           （E）

E: They increase the chances that the animal will be selected as a mate.

28-14: The passage suggests that relatively bright carotenoid-based coloration is a signal of which of the following characteristics in males of certain animal species?

A: Readiness for mating behavior

B: Ability to fight

C: Particular feeding preferences

D: Recovery from parasite infestation     

E: Fitness as a mate                （E）

Carotenoids, a family of natural pigments, form an 

important art of the colorful signals used by many animals.

自然色素为许多动物所用。

Animals acquire carotenoids either directly (from the plants 

and algae that produce them) or indirectly (by eating insects) 

and store them in a variety of tissues.

直接从植物摄取或间接从昆虫取得。

Studies of several animal

species have shown that when choosing mates, females prefer males 

with brighter carotenoid-based coloration.

雌性喜欢鲜艳颜色的雄性。

Owens and Olson 

hypothesize that the presence of carotenoids, as signaled 

by coloration, would be meaningful in the context of mate 

selection if carotenoids were either rare or required for 

health. 

假设这些色素可能稀有或有益健康。

The conventional (Line 15) view is that carotenoids

 are meaningful because they are rare: healthier males can 

forage for more of the pigments than can their inferior 

counterparts.

传统认为色素因稀有而有意义：健康的雄性可以获得更多的色素。

Although this may be true, there is growing 

evidence that carotenoids are meaningful also because they 

are required: they are used by the immune system and for 

detoxification processes that are important for 

maintaining health. 

但有证据表明，色素也有利于健康。

It may be that males can use 

scarce carotenoids either for immune defense and 

detoxification or for attracting females. 

雄性可能将色素用以健康和吸引雌性两个方面。

Males that are more susceptible to disease and parasites 

will have to use their carotenoids to boost their 

immune systems, whereas males that are genetically 

resistant will use fewer carotenoids for fighting 

disease and will advertise this by using the pigments 

for flashy display instead.

容易生病的雄性浪费色素，有抵抗力的雄性节省色素并展现出来。

28-13: Information in the passage suggests that which of the following is true of carotenoids that a male animal uses for detoxification processes?

A: They were not acquired directly from plants and algae            反

B: They cannot be replenished through foraging.            反

C: They cannot be used simultaneously to brighten coloration.            反

D: They do not affect the animal’s susceptibility to parasites.           （E）            无准确论述

E: They increase the chances that the animal will be selected as a mate. 符合中心内容
