    平时大家可以通过阅读的方式来积累词汇和素材资料,下面小编为大家带来了GRE阅读精选文章内容及解析,希望帮助大家通过阅读来提高自己的分析能力和阅读能力,当然想要在能力方面得到提高并不是一朝一夕的事,需要坚持进行有效的练习。
 
    Each of two particular inspection systems that are based on different principles would detect all product flaws but would also erroneously reject three percent of flawless products.Assuming there is no overlap between the products erroneously rejected by the two systems and also no interference between the systems if both operate, using both systems and rejecting only those products found flawed by both would be a way of avoiding all erroneous rejections.

    Which of the following most precisely characterizes the reasoning in the argument?

    (A)The reasoning is conclusive, that is, the conclusion cannot be false if the statements offered in its support are true.

    (B)The reasoning is strong but not conclusive, if the statements offered in support of the conclusion are true, they provide good grounds for that conclu-sion, though it is possible that additional infor-mation might weaken the argument.

 

    (C)The reasoning is weak; the statements offered in support of the conclusion, though relevant to it, by themselves provide at best inadequate grounds for the conclusion.

    (D)The reasoning is flawed in that the conclusion is no more than a paraphrase of one of the pieces of evidence offered in its support.

    (E)The reasoning is flawed in that the argument treats evidence that a factor is necessary to bring about an event as if it were evidence that the factor is sufficient to bring about that event.

    答案:A

    GRE阅读文章会涉及到各个专业,各个方面的知识,地理、地质、气候学、数学、物理、生物、文学、社会问题等无所不包。我们对GRE的阅读文章的题材进行归类梳理,大致可以分为四类:自然科学、生命科学、社会科学和人文学科。接下来逐一进行分析。

    GRE阅读中自然科学类的文章关于纯理科的内容不多,大多与当前的实用科学热点相关,例如地质、气候、天文、海洋、地球,还有一些是关于数学,物理和化学方面的内容。环保、气候变化、新发明、新材料、新能源等与人们的生活密切相关的内容也会出现在自然科学类的文章里。这类的文章叙述直截了当,难度不是很大,考生可以好好把握。

    具体对于阅读文章中的内容如何进行分析,下面小编通过举例方式来帮助大家掌握阅读的方法。

    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。

    掌握好了主题句判断方法,很多文章学生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 infect more plants than do any other fungi and are necessary for many plants to thrive, but they have escaped widespread investigation until recently for two reasons. First, the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely 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。
