There are two factors which determine an individual's intelligence. The first is the 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 order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail 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 demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

As a reliable travel agency, we really do try to describe our centers and accommodation as realistically as possible. All our Super Centers and Main Centers have been extensively investigated during the winter season 1975-1976. As a result we have first-hand information on the way in which hotels, life networks and ski schools, etc. operate during the season. We have not been able to investigate, at first hand, all our Independent Centers during the last season but all have been visited during the past three seasons. Should you need any more information about these centers we will try to get it for you. Our American centers have been investigated on our behalf by United Airlines Tours Department and by the U. S. tour operators who are assisting United and ourselves to offer you this novel program to the United States.
Where possible we have eliminated the use of superlatives from the text (possibly making our brochure(小册子) less attractive to read than it might be) and have concentrated on as accurate a description as possible. Nevertheless you should bear in mind that your opinion and the opinion of our investigator might differ and there may be changes between the time of a visit by our investigator and the visit of one of our customers.
We trust that it is evident to you that we have done all in our power to eliminate misdescription and that there really is no question of misrepresenta-tion on our part—either careless or otherwise. We welcome your constructive criticism—it is the best way we know of improving our brochures and our service. Although complaints are very expensive to handle, your complaint or criticism will be thoroughly investigated and a refund (退赔 ) made if it is justified—none will be made if it isn't.来源：http://www.hxen.net
