　　Ⅳ.阅读理解

　　A

　　Along the river banks of the Amazon and the Orinoco there lives a bird that swims

　　before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow

　　and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.

　　In appearance, the birds of both sexes look very much alike with brown on the

　　back and cream and red on the underside. The head is small, with a large set of

　　feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common

　　birds, cuckoos. Its most striking feature, though, is only found in the young.

　　Baby hoatzins have a claw on the leading edge of each wing and another at the

　　end of each wing tip. Using these four claws, together with the beak (喙), they can climb about

　　in the bushes, looking very much like primitive birds must have done.

　　When the young hoatzins have learned to fly, they lose their claws.

　　During the drier months between December and March hoatzins fly about the

　　forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they

　　collect together in smaller living units of two to seven birds for producing purposes.

　　【语篇解读】　文章主要介绍了生活在亚马逊河的麝雉the hoatzin的外表特征以及生活习性。

　　B

　　The research team has discovered that subordinate fish voluntarily diet to avoid

　　challenging their larger competitors. “In studying gobies we noticed that only the

　　largest two individuals, a male and female, had breeding (繁殖) rights within the group, ” explains Marian Wong. “All other group members are nonbreeding

　　females, each being 5～10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”

　　The reason for the size difference was easy to see. Once a subordinate fish grows

　　to within 5～10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not,

　　the_evicted_fish is then eaten up.

　　It appeared that the smaller fish were keeping themselves small in order to avoid

　　challenging the boss fish. Whether they did so voluntarily, by restraining how much

　　they ate, was not clear. The research team decided to do an experiment. They tried to

　　fatten up some of the subordinate gobies to see what happened. To their surprise, the

　　gobies simply refused the extra food they were offered, clearly preferring to remain

　　small and avoid fights, over having a feast.

　　The discovery challenges the traditional scientific view of how boss individuals

　　keep their position in a group. Previously it was thought that large individuals simply

　　used their weight and size to threaten their subordinates and take more of the food for

　　themselves, so keeping their competitors small.

　　While the habits of gobies may seem a little mysterious, Dr. Wong explains that

　　understanding the relationships between boss and subordinate animals is important to

　　understanding how hierarchical (等级的) societies remain stable.

　　The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread

　　the voluntary reduction of food intake is in nature，” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve

　　health or increase attractiveness, rarely does it improve long­term health and males

　　regularly prefer females that are fatter than the females' own ideal.”

　　【语篇解读】　人类节食是为了让自己看起来更加美丽动人，而鱼类节食则是为了避免纷争，避免自己被赶出种群，而最终被吃掉。

　　5．When a goby grows to within 5～10% of the size of its larger competitor, it________.

　　A．faces dangerB．has breeding rights

　　C．eats its competitorD．leaves the group itself

　　答案　A　[细节理解题。根据第三段第二句可知， 当a goby长到较大的鱼的5～10%时，会引起一场争斗。争斗的结果通常是较小的goby被驱赶出去。故选A。]

　　6．The underlined words “the evicted fish” in Paragraph 3 refer to ________.

　　A．the fish beaten upB．the fish found out

　　C．the fish fattened upD．the fish driven away

　　答案　D　[词义猜测题。根据前面一句提到的the smaller goby being driven away from the group可知the evicted fish应指前面被驱赶走的鱼。]

　　7．The experiment showed that the smaller fish ________.

　　A．fought over a feast

　　B．went on diet willingly

　　C．preferred some extra food

　　D．challenged the boss fish

　　答案　B　[推理判断题。根据第四段中的最后一句以及最后一段的第一句可知。]

　　8．What is the text mainly about?

　　A．Fish dieting and human dieting.

　　B．Dieting and health.

　　C．Human dieting.

　　D．Fish dieting.

　　答案　D　[主旨大意题。第一段应是文章的中心；下文是围绕goby这种鱼节食进行的研究。]
