5．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．In some degree，our intelligence is given to us at birth，and no education can make a talent（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 environment．Therefore，the limits of person's intelligence are fixed（固定）at birth，whether or not he reaches those limits will depend on his environment．This point of view is now held by most experts．
It is easy to show that intelligence is something that we are born with．The closer the blood relationship between two people，the closer they are likely to be intelligence．If we take two strangers by chance from the population，it seems that their degree of intelligence will be completely different．If，on the other hand，we compare two twins，they will very likely 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 twins and put them in different environments．We might send one，for example，to a university and the other to a factory separately where the work is boring．We would soon find differences in intelligence developing，and this shows that environment as well as birth plays an important role．This conclusion is also suggested by the fact that people who live in close contact （接觸） with each other，but who are not related at all are likely to have similar degree of intelligence．
