2011GMAT语法全解：GMAT语法题如何复习

我们应该先分析原句结构,抓住主线,该句属于平行结构形式,D和E中的think与view在意思上形成对应,所以我们不应对这两个答案带有任何偏见,而应一视同仁。根据GMAT语法原则,不能随意省略成分,否则句意就会出现ambiguity。比较五个选项,只有D的句意表达最完整。而为什么要使用think一词我们大可不必去追究,这只是无关痛痒的小问题。　　3。Unlike the acid smoke of cigarettes,pipe tobacco,cured by age-old methods,yields an alkaline smoketoo irritating to be drawn into the lungs。　　(A) Unlike the acid smoke of cigarettes,pipe tobacco,cured by age-old methods,yields an alkaline smoke　　(B) Unlike the acid smoke of cigarettes,pipe tobacco is cured by age-old methods,yielding an alkaline smoke　　(C)Unlike cigarette tobacco,which yields an acid smoke,pipe tobacco,cured by age-old methods,yields an alkaline smoke　　(D) Differing from cigarettes’ acid smoke,pipe tobacco’s alkaline smoke,cured by age-old methods,is　　解答本题时首先排除的是D答案,因为differ from不能用在句首。本题的正确答案为C,但是很多考生的目光都是在C上暂作停留就转向其他选项了。原因是C中连用了两个yield,这样的句子毫无美感可言,缺乏变化。
