GRE阅读什么时候开始备考

阅读需要掌握的单词比考GRE所需掌握的单词要少的多，对词汇的掌握也没有模拟。这些词往往都是些GRE阅读专署词汇，且重复率很高，只需集中背记一下就可以解决基本问题。

另外，读句子，尤其是读长难句，比较容易入手的读法是先找句子的主、谓、宾成分，尤其是谓语动词，很多句子结构复杂，由很多从句组成，一句读下来可能会不解其义，开始读的时候，如果能从句子的主干读起，就能相对容易地把握句子的大意。

掌握了阅读的正确步骤，并有了阅读的基本准备。

对于考生，知道这些还远远不够，怎样在具体的阅读中灵活的运用这些方法，使得做题速度和正确率的均有所提高才是最终的目标。

因此，将做阅读的理论用于实践这个环节必不可少。初期，作者建议可以先精读几篇文章，目的是从阅读过程中，熟悉阅读的方法和掌握阅读的技巧。

考生对阅读知识有了准备后，就需要实际的实践，这个过程可能会很长。因为它是一个过渡阶段，考生要将所掌握的阅读方法真正地运用到阅读中去，这就需要一个时间去适应，要讲好的阅读方法真正地转变成自己的东西。

The finding that there were rock-melting temperatures on asteroids for sustained periods is puzzling: asteroids’ heat source is unknown, and unlike planet-sized bodies, such small bodies quickly dissipate heat. Rubin suggests that asteroids’ heat could have derived from collisions between asteroids. Skeptics have argued that a single impact would raise an asteroid’s overall temperature very little and that asteroids would cool too quickly between impacts to accumulate much heat. However, these objections assumed that asteroids are dense, solid bodies. A recent discovery that asteroids are highly porous makes Rubin’s hypothesis more plausible. When solid bodies collide, much debris is ejected, dissipating energy. Impacts on porous bodies generate less debris, so more energy goes into producing heat. Heat could be retained as debris fall back into impact craters, creating an insulating blanket.

1. The passage suggests that one factor that has made it difficult to account for the temperatures once reached by asteroids is

A. a miscalculation of the frequency of asteroid collisions

B. a misconception about asteroids’ density

C. a mistaken assumption about what the heat source of the asteroids was

D. an underestimation of the rate at which small bodies lose heat

E. an erroneous view of how asteroids were formed

Consider each of the choices separately and select all that apply.

2. It can be inferred from the passage that Rubin disagrees with skeptics mentioned in the passage about which of the following?

A. Whether porous bodies generate less debris when struck than do solid bodies

B. The temperatures asteroids would have to reach for their rocks to have melted

C. The likely effect of impacts on asteroids’ temperatures

答案：

B C

GRE考试阅读理解模拟试题及答案

Benjamin Franklin is portrayed in American history as the quintessential self-made man. In “Self-reliance”, Emerson asks, “Where is the master who could have instructed Franklin...?” In fact, Franklin took instruction widely, and his scientific work was highly collaborative. Friends in England sent equipment needed for his electrical experiments, others, in Philadelphia, helped him set up his workshop there. Philip Syng constructed a device for generating electrical charges, while Tomas Hopkinson demonstrated the potential of pointed conductors. Franklin, in addition to being the group’s theoretician, wrote and published its results. His fame as an individual researcher is partly a consequence of the shorthand by which when one person writes about a group’s discoveries, history sometimes grants singular credit for collective effort.

1. Which of the following best describes the function of the highlighted sentence?

A. It states a viewpoint about Franklin with which the author disagrees.

B. It introduces new evidence about Franklin’s role in the collaborative process.

C. It explains Franklin’s reputation in terms of a broad scholarly phenomenon.

D. It emphasizes the extent to which Franklin relied on others in his workshop.

E. It describes Franklin’s approach to writing scientific results.

2. Emerson is mentioned in the passage primarily to

A. Identify the origin of a particular understanding of Franklin

B. Elaborate on a view of Franklin that the author takes issue with

C. Point to a controversial claim about Franklin’s historical legacy

D. Introduce the question of who Franklin’s main scientific influences were

E. Suggests that Franklin was resistant to collaboration with other scientists
