The reasons for a person’s becoming an alcoholic have often been debated by psychologists and other scientists. But recent studies suggest that the problem of alcoholism(酒精中毒) should also be the focus of investigation by biologists.
While such things as hard jobs, boredom, and unhappiness can lead to alcoholism, researchers at a prominent university have found that there may also be a genetic factor involved in alcoholism. In the study, children of alcoholic parents were surveyed. The result showed that the children of alcoholic parents were more likely to become alcoholics themselves than were children of non-drinking parents.
This evidence in itself is not conclusive（令人确信的）about anything. After all, it may be the constant exposure（接触）and easy access to alcohol that cause the children of alcoholics to become alcoholics themselves. But there is more evidence. The study found that children born of alcoholic parents but raised by non-drinking foster（抚养的）parents also were susceptible to alcoholism. This group of offspring（后代）was more likely to take up drinking than youngsters who were born of and raised by non-drinking parents.
Other evidence found in the study suggests that environment does not play as important a role in the development of alcoholism as had been previously thought. The study found that the likelihood of alcoholism was better predicted from the characteristics of the parents than from such environmental characteristics as type of job or level of income.

When I come across a good article in reading newspapers, I often want to cut and keep it. But just as I am about to do so, I find the article on the __1__ side is as much interesting. It may be a discussion of the way to __2__ in good health, or __3__ about how to behave and conduct oneself in society.
