   怎样抓住新GRE阅读文章的主题句呢?GRE考试阅读题中的主题句都会以什么形式出现呢?


  和国内学生写文章不一样,美国人的阅读文章中从来都不出现“I think that,in my opinion,as far as I am considered”此类语言做主题句。通常来说主题句有以下两种形式:
  1. 判断句(含情态动词,系动词,正负褒贬词的句子);2. 概括文章将来结构。
  比如一个句子:Your minds changed my attitude. 这句话中并没有情态动词和系动词,因此这句话自然不是判断句,也就不是主题句。但只要在这句话中加入一个正负褒贬词,即一个词表明作者的态度或观点的词即是判断句了。比如,Your minds successfully changed my attitude即是判断句了。
  另外,如果一个句子不是判断句,只要它能够概括文章将来结构,及文章后面会从哪几个方面来说明,也是主题句。比如,People are living longer now. 这句话一定不是主题句,而如果这句话是,People are living longer now since the improvement of food condition and the development of medical technology.这句话即是主题句了。因为它概括了文章后面会从哪几个方向来进行说明。
  如果考生在新GRE阅读题中掌握好了主题句判断方法,很多文章便可以很快把握文章的结构框架,帮助后面文章的理解。
  比如一篇文章的开头是,Mycorrhizal fungi 1 infect more plants than do any other fungi and are necessary for many plants to thrive, but they have escaped widespread investigation 2 until recently for two reasons. First, the symbiotic 3 association is so well-balanced that the roots of host plants show no damage even when densely 4 infected. Second, the fungi cannot as yet be cultivated in the absence of a living root.
  第一句是明显的判断句,即为主题句。而主题句也同时概括了文章的将来结构,即会从“M真菌影响力很强”和“M真菌过去由于两个原因没有得到广泛研究”。下面马上看到了first和second,我们即知道这两个很难读懂的句子无非是两个原因使得M真菌没有得到广泛研究而已,具体是哪两个原因,我们几乎可以忽略不读。
  总之,在做新GRE阅读时应该运用一些技巧,这样不仅能提高选对选项的效率,还能节省不少的时间。
  以上就是有关解答新GRE阅读题目的介绍,应对新GRE阅读考试的关键是要抓住文章的主题句,大家在平时的复习中要着重练习这一点,希望能够对您的GRE考试有所帮助。
