2 根据以下资料回答第38、39、40题。
Internet use appears to cause a drop in psychological health, according to research at CarnegieMellon University.
Even people who spent just a few hours a week on the Internet experienced more bad feelingsand loneliness than those who were online less frequently, the two-year study showed. Researchersare puzzling over the results, which were completely contrary to their expectations. They expectedthat the Net would prove socially healthier than television, since the Net allows users to choose theirinformation and to communicate with others.
The fact that Internet use reduces time available for family and friends may account for the drop inpsychological health, researchers hypothesized (推测 ). Faceless, bodiless "virtual" (虚的 ) communicationmay be less psychologically satisfying than actual conversation, and the relationships formed through itmay be shallower. Another possibility is that exposure to the wider world through the Net makes usersless satisfied with their lives.
"But it's important to remember this is not about the technology, it's about how it isused," says psychologist Christine Riley of Intel, one of the studies sponsors(发起人 ). "Itreally points to the need for considering social factors in terms of how you design applicationsand services for technology."
What had the researchers expected before the research?

A．Internet use has nothing to do with social health.

B． Internet use may improve social health.

C． The Net may account for the drop in psychological health.

D． Spending much time on the Internet makes people feel bad and lonely.
