问题     Loneliness has been linked to depression and other health problems. Now, a study says it can also spread. A friend of a lonely person was fifty-two percent more likely to develop feelings of loneliness. And a friend of that friend was twenty-five percent more likely to do the same.
    Earlier findings showed that happiness, obesity and the ability to stop smoking can also spread like infections within social groups. The findings all come from a major health study in the American town of Framingham, Massachusetts.
    The study began in 1948 to investigate the causes of heart disease. Since then, more tests have been added, including measures of loneliness and depression.
    The new findings involved more than 5,000 people in the second generation of the Framingham Heart Study. The researchers examined friendship histories and reports of loneliness. The results established a pattern that spread as people reported fewer close friends.
    For example, loneliness can affect relationships between next-door neighbors. The loneliness spreads as neighbors who were close friends now spend less time together. The study also found that loneliness spreads more easily among women than men.
    Researchers from the University of Chicago, Harvard and the University of California, San Diego, did the study. The findings appeared last month in the Journal of Personality and Social Psychology.
    The average person is said to experience feelings of loneliness about 48 days a year. The study found that having a lonely friend can add about 17 days. But every additional friend can decrease loneliness by about five percent, or two and a half days.
    Lonely people become less and less trusting of others. This makes it more and more difficult for them to make friends—and more likely that society will reject them.
    John Cacioppo at the University of Chicago led the study. He says it is important to recognize and deal with loneliness. He says people who have been pushed to the edges of society should receive help to repair their social networks.
    The aim should be to aggressively create what he calls a "protective barrier" against loneliness. This barrier, he says, can keep the whole network from coming apart.
What is the main idea of the passage?
选项 A、Loneliness can spread.
B、Loneliness is linked to depression.
C、Lonely people tend to grow fat.
D、Lonely people need more friends.
答案A
解析 文章首先指出一项研究表明孤独可以蔓延，接着介绍了这项研究及其研究结果，最后说明孤单传播带来的不良影响及应对方法，由此可见，本文主要是围绕孤单可以传播展开的，故答案为[A]。[B]在首段首句提到了，但不是本文重点讲述的内容，故排除。[D]是针对第七段末句设的干扰项。
