2、篇首覆盖法

　　如果一个单词的多种形式（同词、同义/反义词、同根词）或短语在一篇文章的篇首反复出现，那么这个单词或短语则是文章的主题词。

　　【举例讲解】

　　例：I was addressing a small gathering in a suburban Virginia living room - a women's group that had invited men to join them. Throughout the evening, one man had been particularly talkative, frequently offering ideas and anecdotes, while his wife sat silently beside him on the couch. Toward the end of the evening, I commented that women frequently complain that their husbands don't talk to them. This man quickly nodded in agreement. He gestured toward his wife and said, "She's the talker in our family." The room burst into laughter; the man looked puzzled and hurt. "It's true," he explained. "When I come home from work I have nothing to say. If she didn't keep the conversation going, we'd spend the whole evening in silence."

　　29. Which of the following can best summarize the main idea of this text?

　　B. Marriage break-up stems from sex inequalities

　　C. Husband and wife have different expectations from their marriage

　　D. Conversational patterns between man and wife are different

　　根据题干特征可知这是一道主旨题，主旨题可利用主题复现法来解，通过抓前两段的主题词可确定全文中心。本文我们利用主题词复现的形式：同词复现、同义复现以及同根复现可以找出前两段的复现有"talkative"，"talk"，"talker"以及"conversation"，因此我们可以确定该篇文章的主题词是"交谈，交流"，D项中的"Conversational patterns"是主题词的同根复现，故正确。A项和B项的错误属于无中生有，C项的干扰性较大，很多考生会错选该选项，但只要把握好全文主题词是"talk"，这个选项也是很好排除的。
