GRE阅读主题句分析
英语课
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. 这句新GRE考试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,新GRE阅读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,当然还要背诵一些GRE阅读词汇。
上述就是小编总结的新GRE考试阅读重点,复习备考新GRE阅读的时候考生们要多注意一下这些方面。掌握一些GRE阅读词汇,而且上述的几方面都是阅读复习的重点,祝大家复习顺利。
