Are some people born clever and others born stupid? Or is intelligence (智力) 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 (天才)
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 surrounding (环境). 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 supposed 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 intelligent. 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 likely to 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 (完全相同的) twins and put them in different environments.
We might send one,for example,to a university and the other to a factory where the working is boring.
We would soon find differences in intelligence developing,and this shows 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.
