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.

| Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
