GRE阅读主题句藏在文章里找不到?你需要这些准确定位技巧

GRE阅读主题句出现形式介绍

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。

GRE阅读主题句定位技巧实例讲解

以这句话为例：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。

为什么要学定位主题句技巧?

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 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。

综上所述，在做GRE阅读时，秒选定位主题句的方法和技巧是非常实用的，希望大家都能学会掌握和运用这种技巧，提高选对选项的效率，节省考试时间。

Partha has withdrawn its troops from Baltia after five years of occupation. Earlier this year the country of Cardcna began shipping mules to Baltia's resistance fighters to facilitate transport of weapons across Baltia's mountains to the battle areas. Cardena's diplomats now claim that without

Cardena's aid to Baltia's resistance fighters, Partha would not have withdrawn.

(B) During the past year, Cardena shipped weapons and food, as well as mules, to resistance fighters in Baltia.

(C) Last year a new government took power in Partha and decided that national interests were not served by the occupation of Baltia.

问题: 下面哪一个如果正确的话,最能反对外交家断言的正确性

读题: 在5年的占领后，P从B撤军。今年的早些时候C开始运送骡子给B的抵抗部队，以方便在B国山区的运输。现在C外交官宣称，没有C的帮助，P不会撤军。

分析:题中第一句话就告诉我们一个事实，P从B撤军了，而C外交家断言说:这是因为C的 帮助，问题是反对C外交官的宣称，也就是要反对原因。

两种weaken反对方式:

1、 直接说到和原因不一样就对。

2、 有其它的原因来解释P为什么撤军(这种题型中这种答案占多数)

B、去年, C运送武器,食物和骡子给B国抵抗部队 support，和原因是相同点。

C、去年P国一个新政府上台，认为占领B并没有获利 weaken, 其他原因解释为什么撤军, 占领并不获利,所以撤军

E、抵抗部队和P国军队战斗了5年。 不要进一步联想是抵抗部队打跑了P，它只是说战斗而已

How can the hormone adrenaline that does not act directly on the brain have a regulatory effect on brain function? Recently, we tested the possibility that one of the hormone's actions outside the brain might be responsible. Since one consequence of adrenaline release in an animal is an increase in blood glucose levels, we examined the effects of glucose on memory in rats. We found that glucose injected immediately after training enhances memory tested the next day. Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline's ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline. These results are as they should be if adrenaline affects memory modulation by increasing blood glucose levels. (131 words)

10.The author refers to the results of the experiment using adrenergic antagonists as "negative findings" most likely because the adrenergic antagonists

(A) failed to disrupt adrenaline's effect on memory

(B) did not affect glucose's ability to enhance memory.

(C) did not block adrenaline's ability to increase blood glucose levels

(D) only partially affected adrenaline's ability to enhance memory

(E) disrupted both adrenaline's and glucose's effect on memory

Our words are meaningless and cannot be distinguished from their opposites, as can be proved by an example. People think that they know the difference between the meanings of "bald" and "having hair." Suppose an average person twenty-one years of age has N hairs on his or her head. We say that that person is not bald but has hair. But surely one hair less would make no difference, and a person with N-1 hairs on his or her head would be said to have hair. Suppose we kept on, with one hair less each time. The result would be the same. But what would be the difference between someone who had one hair and someone who had none? We call them both bald. Nowhere can we make a distinction between "bald " and "having hair."

Which of the following statements best counters the argument above?

The word "bald" can be translated into other languages.

A word can have more than one meaning.

A word such as "cat" can be applied to several animals that differ in some respects.

Words can lack precision without being meaningless.

People cannot think clearly without using words.

答案：(D)

That sales can be increased by the presence of sunlight within a store has been shown by the experience of the only Savefast department store with a large skylight. The skylight allows sunlight into half of the store, reducing the need for artificial light. The rest of the store uses only artificial light. Since the store opened two years ago, the departments on the sunlit side have had substantially higher sales than the other departments.

Which of the following, if true, most strengthens the argument?

(A) On particularly cloudy days, more artificial light is used to illuminate the part of the store under the skylight.

(B) When the store is open at night, the departments in the part of the store under the skylight have sales that are no higher than those of other departments.

(C) Many customers purchase items from departments in both parts of the store on a single shopping trip.

(D) Besides the skylight, there are several significant architectural differences between the two parts of the store.

(E) The departments in the part of the store under the skylight are the departments that generally have the highest sales in other stores in the Savefast chain.
