IV. 阅读理解

Most animals only have animals of a different kind for food. But sometimes two kinds of animals come together in a partnership (伙伴关系) which is good for them. You may have noticed some birds on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep let the birds do so because they can stop the parasites from troubling them. So though they can do with it by themselves, they can do better together with each other.

　　Sometimes an animal has a plant partner. The relationship develops until the two partners cannot do without each other. This is so in corals of the sea. Inside their bodies they have very small plants, which act as “cleaners”, taking the useless things from the coral and giving oxygen in return. That is what the animal needs to live. If the plants are killed, or are even kept from receiving light so that they cannot live as usual, the corals will die.

　　1.Some birds like to sit on a sheep because ________.

　　A. they can eat its parasites     B. they enjoy traveling with the sheep

　　C. they can’t live without its parasites  D. they want to find the warm place

　　2.The underlined word “they” in the first paragraph means _________.

　　A. birds and parasites       B. birds and sheep

　　C. parasites and sheep       D. birds, parasites and sheep

　　3.We learn from the passage that corals need plants for _______.

　　A. friends  B. light   C. food   D. oxygen

　　4.The Chinese for the word “oxygen” is _________.

　　A. 氧气  B. 空气   C. 废气  D.二氧化碳

　　5.What is the second paragraph mainly about?

　　A. Some animals and plants cannot live without each other.

　　B. Some animals and plants cannot develop their friendship easily.

　　C. Some plants eat each other.

D. Some animals live better together.

III. 1.A. 后面这句话是前面内容的原因，这从句子的意思上可以直接看出来。

2.C. 孩子们与Ben开玩笑的原因是他的反应较慢，这从所给的四个词的词义上可以看出。

3.B. 由于孩子们的学习不好，他们的母亲才会做出决定自己努力去帮助他们。

4.C. 到图书馆肯定是去读书的。

5.A. 根据下句“the teacher held up a rock” 可知这是在课堂上。

6.D. 根据上句“Ben put up his hand” 可以知道Ben 举手之后，老师是会让他发言的。

7.D. 前文已经提到，Ben的反应较慢，所以他从不回答老师的问题的。这次，他举手回答问题，当然同学们会感到怀疑。

8.C. 根据下句“he said a lot about it” 可知Ben对rock 应该上懂的很多。

9.C. 根据所给词语的词义可知答案。

10.B. 当听完Ben的回答之后，老师和同学们一定会吃惊的。

11.D. Ben的这些知识都是从他读的书籍的报导中得到的，这是人们在图书馆中获取知识的途径。

12.A. 根据下句“When he finished high school, he went to Yale University.”可知Ben已经成为了一名好学生。

13.A. Ben 的一些知识和思想是从他母亲那里学来的。

14.B. Ben现在所懂的知识是他小时候所不了解的，其实任何人都是这样的。

15.A. 文章整体贯穿的是读书。

IV. 1.A.本题属于表层理解题。答案即在“This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep.”一句之中。

2.B.前文中的“The sheep let the birds do so because they can stop the parasites from troubling them.”的意思是说“绵羊让鸟儿落在自己身上，因为鸟儿可以将它们身上的寄生虫吃掉。”；另一句“So though they can do with it by themselves…”的意思是说“尽管它们自己也能对付寄生虫……”。综合上面两句话的意思，再结合“…they can do better together with each other.”这一句话，即得答案。

3.D.显然，根据“…taking the useless things from the coral and giving oxygen in return. That is what the animal needs to live.”这两句话可知，珊瑚需要植物提供的氧气才能生存下去。

4.D.联系生物学常识，氧气是各种生物赖以生存所必需的，所以由此可以推测出该词的意思是“氧气”。

5.A.根据这一自然段的内容，珊瑚和它们体内的植物具有相互依存的关系。因此，答案非A莫属。选项D迷惑性较大。因为这一自然段主要说明了珊瑚与体内植物的关系，它们在一块生存得很好。但选项D意思是“一些动物在一起生存得更好。”只要注意“动物”和“植物”这两个字眼，即可将此项排除。
