GMAT8月考试的一些答疑 -

1.When drive-ins were at the height of their popularity in the late 1950’s, some 4,000 existed in the United States, but today there are less than one-quarter that many.
A. there are fewer than one-quarter of that amount （答案）
B. the number is less than one-quarter the amount
B选项错，但错的地方自己不是很明确，不知one-quarter the amount这种说法有没有，是不是要加of，答案解释说number没有指代对象，但个人认为number不是清楚指代4000吗？为什么说number没有指代对象呢？
A选项中个人认为fewer是修饰人的，那么也应该和人比较，而one-quarter of that amount是数啊，所以认为它们无法比较，不知自己的想法错在哪里？感觉选项都不是很正确。
------A正确，FEWER是修饰人和可数事物的，这里可以。ONE QUARTER THAT AMOUNT可以这么用，关键在于，THE NUMBER是指现在的数目还是1950年代时候的4000？指代不明。
GWD-9-Q1
A mixture of poems and short fiction, Jean Toomer’s Cane has been called one of the three best novels ever written by Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man.
A. Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison
B. a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man
这道题好像有些争议，答案给的是B，但是有的版本给的是A，不知老师的看法是什么？PS：written在这句话中修饰的是three best novels吗？
-----------这里是A正确，破折号后面的语句修饰的是THE THREE BEST NOVELS，所以原文应该反过来把小说放在前面。B明显不对，这个A BLACK AMERICAN不正确。
Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system’s ability to deal with all other pollutants.
A. an especially serious pollutant because it diminishes the respiratory system’s ability to deal
B. a specially serious pollutant because it diminishes the capability of the respiratory system to deal
这道题也有争议，个人认为A选项的’s一般修饰的是有生命的物体，应该用of结构更好，但是B选项specially的用法又觉得不合适，不知老师的看法如何？
-------？？？？A选项和原文是一样的啊。 SPEICALLY也正确，但是没有ESPEICIALLY好一些。
Analyzing campaign expenditures, the media has had as a focus the high costs and low ethics of campaign finance, but they have generally overlooked the cost of actually administering elections, which includes facilities, transport, printing, staffing, and technology.
A. In analyzing campaign expenditures, the media have focused on
通过比较A选项是最合理的，但是不明白analyzing前面为什么前面为什么要加in呢？
-------加上IN 更合理，因为媒体不会自己去分析，而是找人分析，所以分析竞选金额是一个过程PROCESS。
逻辑题：
1． Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted. This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job. On the contrary, since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base. The high success rate shows insufficient canvassing effort.
Which of the following, if true, provides more support for the argument?
A. Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.
B. This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the university’s fund-raisers having made any contact with the donors.
个人认为B也可以support，即大部分donations都是之前来自以前就捐款的人，不需要raiser联系他们，那不就是说明了他们不努力吗？
---------嗯，你的考虑有问题。注意，这段话的主旨是筹款人不努力，因为他们只联系了本来就已经打算捐款的人。B这个选项是无关的，如果捐款的人无所谓你联系不联系，那你说能SUPPORT他们是努力还是不努力的论点吗？肯定不对。反倒是A，你看，筹款委员会联系了所有人，想捐的和不想捐的，结果80%的捐款人还是本来就有意愿要捐钱的，那么说，基本上本来不想捐的潜在客户成功率很低，直接证明他们不努力。要从证据的加强上入手！
2． Which of the following most logically completes the argument below?
Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflections they produce. Because many of those large satellites have ceased to function, the proposal recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since .
-----要读懂了，这里说的是摧毁大卫星不一定能缓解地球天文望远镜的干扰。
A. the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth
---------把望远镜像哈勃一样放到更高的太空？这不能证明This proposal, however, is ill conceived，必须要和PROPOSAL（炸掉大卫星）有关才行。
B. a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible
----- blanket of reflections，perfect！！！
个人认为AB均能weaken这个proposal，这种手段-方法型问题要么驳斥方法不可行或是方法达不到目的，A选项表明了只能……才能达到目的，不也是驳斥了proposal不可行吗？
--------是，手段和方法的改变能够WEAKEN，但是这里明确说了前半句话是THIS PROPOSAL，从本身上讲，A也能WEAKEN，但是效果绝对没有B好，B提出的观点是，炸掉大卫星的理论出发点是大的东东比小碎片更值得炸，因为他们发射多，结果呢，炸掉大的，反倒成了一片金属云，反射更多了，这不是适得其反吗？这个削弱，最直接也是最有力的，直接把原观点彻底炸掉。
