    There are two factors which determine an individual's intelligence. The first is sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of the environment in which he is brought up. If an individual is handicapped (受阻碍) environmentally, it is likely that his brain will stop to develop and he will never attain the level of intelligence of which he is capable.

    The importance of environment in determining an individual's intelligence can be proved by the identical twins, Peter and John. When the twins were three months old, their parents died, and they were placed in separate foster (寄养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. John, however, was educated in the home well-to-do parents who had been to college. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. John's IQ was 125, twenty-five points higher than the average and fully forty points higher than his brother.
