问题    Internet use appears to cause a drop in psychological health, according to a research at Carnegie Mellon University.
   Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.
   The fact that Internet use reduces time available for family and friends may account for the drop in psychological health, researchers hypothesized(推测). Faceless, bodiless "virtual" (虚的)communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives.
   " But it’ s important to remember this is not about the technology, it’ s about how it is used, " says psychologist Christine Riley of Intel, one of the study’ s sponsors (发起人). " It really points to the need for considering social factors in terms of how you design applications and services for technology. "
What’ s the finding of the research undertaken at Carnegie Mellon University?
选项 A、People spend more time on the Internet now.
B、People spend less time with their families and friends now.
C、The Net proves socially healthier than television.
D、Internet use may cause a drop in psychological health.
答案D
解析 细节题。根据文章第一段可知，卡耐基梅隆大学的研究结果表明网络造成人的心理健康水平下降，所以选项D(网络使用造成心理健康水平下降)正确。选项A(人们现在花在网上的时间越来越多)和选项B(人们现在花在家人和朋友身上的时间越来越少)是事实，不是研究结果。从第二段最后一句可以看出，选项c(网络在社交上而言比电视更健康)是研究者的期望，而不是研究结果。故本题选D。
