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

选项 A、cultivate
B、kick
C、leave
D、tick
答案B
解析 本题要求考生判断空格处应填入的适当的动词。本句提及人们……此习惯的决定会被交际圈中其他人戒烟所影响，“此习惯”指上文中的smoking吸烟。文章主题是行为或现象在交往圈中传播，那么戒烟也会在交往圈中传播。所以，本句在说“戒除这个习惯会受到其他人戒烟的影响”，因此，B选项kick符合题意，kick除了“踢”的含义之外，还有object(拒绝、戒除)的含义，而且kick the habit为固定搭配，表示戒除某不良嗜好。
