问题     My Space and other Web sites have unleashed a potent new phenomenon of social networking in cyberspace,【1】at the same time, a growing body of evidence is suggesting that traditional social【2】play a surprisingly powerful and under-recognized role in influencing how people behave.
    The latest research comes from Dr. Nicholas A. Christakis, at the Harvard Medical School, and Dr. James H. Fowler, at the University of California at San Diego. The【3】reported last summer that obesity appeared to【4】from one person to another【5】social networks, almost like a virus or a fad. In a follow-up to that provocative research, the team has produced【6】findings about another major health【7】: smoking. In a study published last week in the New England Journal of Medicine, the team found that a person’s decision to【8】the habit is strongly affected by【9】other people in their social network quit—even people they do not know.

选项 A、totaled
B、increased
C、summed
D、added

答案A

解析 本题要求考生根据上下文选择符合原文含义的动词。通过分析that引导的从句我们可以看出,定语从句的主语就是that,代替了先行词a network(交际圈),单独考虑从句,其意思是“交际圈……12,067人”。解该题的关键是判断适当的动词,完成这个句子的搭配。据此判断,A选项totaled表示summed up to,后面加数字信息,因此A选项符合语境。
