Passage B 研究表明，使用因特网可能会导致心理健康的下降。上网次数多的人与较少的人相比，这种可能性有明显差异。这不是说已经有不良感觉的人在网上花费了更多的时间，而是说使用因特网似乎确实诱发了人们的不良感觉。研究人员对这些结果感到困惑，因为这与他们的预料截然相反。他们预测，和看电视相比，从社交角度来说，上网可能更健康一些，因为网络允许使用者选择自己需要的信息并且和别人进行交流。
Passage B It appears that Internet-using may cause a decline in psychological health, according to research. People who spent a few hours a week on the internet experienced more depression and loneliness than those who logged on less frequently. And it doesn’t mean people who were already feeling bad spent more time on the internet, but using the net actually appeared to cause the bad feelings. Researchers are puzzled over the results, which were completely contrary to their expectations. They expected that the net would prove socially healthier than TV, since the net allows users to choose information they need and to communication with other.
