　　原文与解析：

　　Are some people born clever, and others bornstupid?Or is the development of intelligencedependent on environment and experience?Strangely enough, the answer to both questions isyes. To some extent, our intelligence is given us atbirth. On the other hand, [33]a child who lives in aboring environment will develop his intelligenceless than one who lives in rich and varied surroundings.

　　It is easy to show that intelligence is something we are born with.The closer the bloodrelationship between two people, the closer they are likely to be in intelligence. Therefore if wetake two unrelated people at random from the population, it is likely that their degree ofintelligence will be completely different.If we take two identical twins, they will very likely be asintelligent as each other. [34]Relations like brothers and sisters, parents and children, usuallyhave similar intelligence, and this clearly suggests that intelligence depends on birth.

　　Imagine that we take two identical twins and put them in different environments. We mightsend one, for example, to a university and the other to a factory where the work is boring. Wewould soon find differences in intelligence development, and this indicates that environmentas well as birth plays a part. This conclusion is also suggested by the fact that [35]people wholive in close contact with each other, but who are not related at all, are likely to have a similardegree of intelligence.

　　33. What degree of intelligence might a child have, if he lives in a rich and variedenvironment?

　　正确答案：A

　　解析：选项A、B、C中的surroundings, environment和circumstance都有“环境”的意思，所以原文提到environment的时候就要留心。原文说在单调环境下生活的孩子比生活在丰富多彩环境下的孩子智力发展得少，故A正确，A中的dull是对原文中boring的同义替换。

　　34. Why does the speaker say that intelligence depends on birth?

　　正确答案：C

　　解析：原文说兄弟姐妹和父母孩子这类关系的人通常来说智力水平相似，这说明智力依赖血统，故选C。

　　35. What do we learn about unrelated people who live in close contact according to thepassage?

　　正确答案：D

　　解析：原文说生活中相互亲密接触、但是并没有任何关系的人，很可能智力水平相似，故D正确。四个选项中只有D含有原文中出现频率最高的词intelligence，仅凭这一点也可以猜测它是正确答案。
