    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. And, surprisingly, entire networks of smokers appear to quit virtually【10】.

选项 A、made a companion
B、took advantage
C、took an attitude
D、had the best
答案B
解析 空格内所填入的信息应该能与空格后的介词of构成固定搭配，该动词词组为句子的谓语成分。前面的主语是they，指两位研究者，宾语成分是detailed records，本题考查的是句子主干的搭配，主干的意思是“他们……详细数据”，从后文enabling the researchers to study a network可以得知，这些数据来源——被试者们——对研究者们的工作有利，因此综合考虑主干信息和后文内容反映出的对数据的态度，选择B选项，they took advantage of the detailed records，即他们采用或利用了详细数据。
