太傻GRE阅读题一篇
The hypothesis of an expanding Earth has never attracted notable support,and if it were not for the historical example of continental drift,such indifference might be a legitimate response to an apparently improbable concept.It should be remembered,however,that drift too was once regarded as illusory,but the idea was kept alive until evidence from physicists compelled geologists to reinterpret their data.
Of course,it would be as dangerous to overreact to history by concluding that the majority must now be wrong about expansion as it would be to reenact the response that greeted the suggestion that the continents had drifted.The cases are not precisely analogous.There were serious problems with the pre-drift world view that a drift theory could help to resolve,whereas Earth expansion appears to offer no comparable advantages.If,however,physicists could show that the Earth’s gravitational force has decreased with time,expansion would have to be reconsidered and accommodated.
1.The passage indicates that one reason why the expansion hypothesis has attracted little support is that it will not
(A) overcome deficiencies in current geologic hypotheses
(B) clarify theories concerning the Earth’s gravitational forces
(C) complement the theory of continental drift
(D) accommodate relevant theories from the field of physics
(E) withstand criticism from scientists outside the field of geology
2.The final acceptance of a drift theory could best be used to support the argument that
(A) physicists are reluctant to communicate with other scientists
(B) improbable hypotheses usually turn out to be valid
(C) there should be cooperation between different fields of science
(D) there is a need for governmental control of scientific research
(E) scientific theories are often proved by accident
3.In developing his argument,the author warns against
(A) relying on incomplete measurements
(B) introducing irrelevant information
(C) rejecting corroborative evidence
(D) accepting uninformed opinions
(E) making unwarranted comparisons
4.It can be deduced from the passage that the gravitational force at a point on the Earth’s surface is
(A) representative of the geologic age of the Earth
(B) analogous to the movement of land masses
(C) similar to optical phenomena such as mirages
(D) proportional to the size of the Earth
(E) dependent on the speed of the Earth’s rotation
我比较看不懂的在第1、第4两题上,请达人解惑.

我不是达人 试着做一下 希望不要全错就好
1 C
2 C
3 E
4 D
对么?
第四题是这句话：If, however, physicists could show that the Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated.既然支持的证据是重力减小,而expansion是体积增大,那就是说gravitational force 和size of earth之间有关联.
第一题选A是不是因为There were serious problems with the pre-drift world view that a drift theory could help to resolve, whereas Earth expansion appears to offer no comparable advantages. 漂移理论被证实,对解决这些问题有帮助,但扩张理论没有相似的好处.这个相似的好处,是不是就是说,漂移理论对当时的学术研究有益,而扩张理论的证实对当前研究没什么帮助?唉,还是不擅于揣度GRE阅读的言外之意.
