2019年GAMT考试阅读经典模拟练习题3

阅读对于我们来说并不陌生，在我们从小到大的考试中都已经有很多经验了，阅读也是我们很容易提分的一个考察科目，所以小编今天带来了这篇阅读练习题，在坦途网GAMT考试频道还有很多相关的内容和试题，现在我们就先来看看这篇文章吧！

(This passage was excerpted from material published in 1996.)

When a large body strikes a planet or moon, material is ejected, thereby creating a hole in the planet and a local deficit of mass. This deficit shows up as a gravity anomaly: the removal of the material that has been ejected to make the hole results in an area of slightly lower gravity than surrounding areas. One would therefore expect that all of the large multi-ring impact basins on the surface of Earth’s Moon would show such negative gravity anomalies, since they are, essentially, large holes in the lunar surface. Yet data collected in 1994 by the Clementine spacecraft show that many of these lunar basins have no anomalously low gravity and some even have anomalously high gravity. Scientists speculate that early in lunar history, when large impactors struck the Moon’s surface, causing millions of cubic kilometers of crustal debris to be ejected, denser material from the Moon’s mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no low gravity anomaly in the resulting basin. Later, however, as the Moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete. Thus today such gravitational compensation probably would not occur: the outer layer of the Moon is too cold and stiff.

35. According to the passage, the gravitational compensation referred to in line 33 is caused by which of the following? (信息题)

A. A deficit of mass resulting from the creation of a hole in the lunar surface

B. The presence of material from the impactor in the debris created by its impact

C. The gradual cooling and stiffening of the Moon’s outer layer

D. The ejection of massive amounts of debris from the Moon’s crust

E. The rapid upwelling of material from the lunar mantle

36. The passage suggests that if the scientists mentioned in line 19 are correct in their speculations, the large multi-ring impact basins on the Moon with the most significant negative gravity anomalies probably(信息题)

A. were not formed early in the Moon‟s history

B. were not formed by the massive ejection of crustal debris

C. are closely surrounded by other impact basins with anomalously low gravity

D. were created by the impact of multiple large impactors

E. were formed when the Moon was relatively elastic

37. Which of the following best describes the organization of the passage? (写法性主题题)

A. An anomalous finding is cited, the data used to support that finding are analyzed, and the finding is modified.

B. A theory about a phenomenon is introduced, data seeming to disprove that theory are analyzed, and the theory is rejected.

C. A phenomenon is described, a finding relating to the phenomenon is discussed, and a possible explanation for that finding is offered.

D. A debate among scientists regarding the explanation for a particular phenomenon is outlined, and one position in that debate is shown to be more persuasive.

E. The observation of an astronomical event is described, and two schools of thought about the explanation for that event are discussed.
