Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very probably be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

题目分析:有些人天生就聪明？而有些人天生就愚钝吗？还是人的智商是随着我们的环境和经验而获得的呢？让人奇怪的是，这些问题的答案都是肯定的。在某种程度上人的智力是天生的，但是随着环境的变化，经验的增长，人的智商也在随之增长。
小题1:D。细节理解题。根据文章第一段问题的回答，以及下文的内容可知一个人的聪明，愚钝是天生的，但是同时人的生活环境和所受的教育也起着很大的作用，故答案选D。
小题2:C。 细节理解题。根据文章第一段Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment.可以判断环境在人后天智商的发展方面起着很重要的作用，所以智商低的孩子在一种好的环境下能够开发最大的潜能，故答案选C。
小题3:C。细节理解题。根据文章内容可知双胞胎的智商应该是相同的，但是在不同的环境下，他们的智力的发展却是不同的，由此判断作者用这个例子来证明环境对人智力的影响，故答案选C。
