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】.
    For【11】of their studies, they【12】of detailed records kept between 1971 and 2003 about 5,124 people who participated in the landmark Framingham Heart Study.  Because many of the subjects had ties to the Boston suburb of Framingham, Mass. , many of the participants were【13】somehow—through spouses, neighbors, friends, co-workers—enabling the researchers to study a network that【14】12,067 people.
    Taken together, these studies are【15】a growing recognition that many behaviors are【16】by social networks in【17】that have not been fully understood. And【18】may be possible, the researchers say, to harness the power of these networks for many【19】, such as encouraging safe sex, getting more people to exercise or even【20】crime.
选项 A、filling
B、blocking
C、fueling
D、contributing
答案C
解析 本题要求考生根据上下文选择符合原文含义的动词。句子的主干是these studies are...a growing recognition，后面that所引导的从句是recognition的同位语从句，涉及行为和社交圈的关系，即文章的主要观点。句子主干大意是：这些研究……进一步的认识。认识的内容如同谓语从句所述，为了便于做本题，暂时忽略。只有C选项fueling可以搭配，意思是“这些研究促进了进一步的认识”。若考虑前文中所述研究，发现都是关于社交圈对现象或行为的传播作用，可见这些研究让人们更加明确社交圈和行为的关系，可以根据文章主旨及语境再度印证C选项的正确性。本题中fuel考熟词僻意。
