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
