185. (GWD-8-Q41)
When drive-ins were at the height of their popularity in the late 1950s, some 4,000 existed in the United States, but today there are less than one-quarter that many.
A.there are less than one-quarter that many
B.there are fewer than one-quarter as many
C.there are fewer than one-quarter of that amount
D.the number is less than one-quarter the amount
E.it is less than one-quarter of that amount
题目释义:when drive-ins were…, 4,000 existed in the United States, but today there are fewer than one-quarter as many.
考点:
比较结构,逻辑表达,句子结构
1.4000这个单独的数字不可能existed in the United States,且数字可以做代词,故4000指代了4000 drive-ins,后面
要用复数形式的谓语动词。
2.amount的用法:GMAT里面AMOUNT的用法解释是:amount is for undifferentiated masses such as sand or water,
即amount用于修饰不可分割的物体,即修饰不可数名词,因为4000 drive-ins是4000个不同的个体所以that amount 不可以修饰4000。
另外amount与less搭配
3.比较。
词组:less/fewer than X percent of Y,less或fewer的选用取决于Y是否可数,本题的比较对象是drive-ins。
既然全句比较的是可数名词,相应地,需要用are、fewer和many/number等与可数名词复数形式相一致的表述。
4.as many的用法(摘自Longman):
as many=a number that is equal to another number 表示同样的数字
They say the people of Los Angeles speak 12 languages and teach just as many in the schools.
in as many days/weeks/games etc.
A great trip! We visited five countries in as many days (=in five days).
*: "twice as many", "one-quarter as many", etc.都是非常常见的用法,记住这样的表达。
选项分析:
(A)one quarter加后面的部分应该是一个可数项,而less修饰不可数名词,且用less的话,前面要用there is,故用less
错误;that many的表达unidiomatic。
(B)Correcet;补全省略即there are fewer than one-quarter as many (as there were at the height of their popularity
in the late 1950s);fewer修饰可数名词正确;one-quarter在此做副词修饰as many,后面不用再加of,类似于twice as many/much as。
(C)amount修饰不可数名词,不能用来修饰4,000(drive-ins)这个可数的量。
(D)the number指代不清;the amount指代不清,只能修饰不可数名词;the number is less没有问题,less和smaller
都可以修饰数字。
(E)it没有指代对象;that amount指代4,000 drive-ins错,amount只能用于修饰不可数名词。
189. (GWD3-Q30) (旧Prep2-131)
Today’s technology allows manufacturers to make small cars more fuel-efficient now than at any time in their
production history.
A.small cars more fuel-efficient now than at any time in their
B.small cars that are more fuel-efficient than they were at any time in their
C.small cars that are more fuel-efficient than those at any other time in
D.more fuel-efficient small cars than those at any other time in their
E.more fuel-efficient small cars now than at any time in
关于指代:前面是单数名词,后面如果要指代,只能用that,如果需要表达复数意思,那么只能重复这一名词的复数形式,如economy-economies,不能随意改成those, ets视之为指代错误。
181. 重点题
The number of people flying first class on domestic flights rose sharply in 1990, doubling the increase of the previous year.
A.doubling the increase of

C.double as much as the increase of
D.twice as many as the increase in
E.twice as many as the increase of
242. (GWD-1-Q38)
Retail sales rose 8/10 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter more than doubled that of the 1.4 percent growth rate in personal spending for the previous quarter.
A.that personal spending in the July-September quarter more than doubled that of
B.that personal spending in the July-September quarter would more than double
C.of personal spending in the July-September quarter, that it more than doubled
D.of personal spending in the July-September quarter more than doubling that of
E.of personal spending in the July-September quarter, that it would more than double that of
题目释义:…, intensifying expectation that PS in J-S quarter would more than double the 1.4 percent growth rate in PS for the previous quarter.
考点:
动词形式(Verb form);逻辑含义(Logical predication)
1.expectations表达将来预测的含义,用同位语从句更能体现时态的精准,而且如果用了of从属结构显得冗长累赘,
句意表达不清。
2.more than double the 1.4 percent growth rate,其中double是动词,more than是副词。
3.对于more than doubled或is more than doubled的区分技巧:把more than脱去不看,doubled是一般过去时,而
is doubled是被动语态
选项分析:
A.that跟在expectations后面表示具体内容;expectations的内容没有实现,不能用过去时;that没有指代。
B.correct;Would在这里表示expectation的内容没有实现。
C.整个句式awkward,that为同位语从句引导词与of平行共同修饰expectations,其实没有必要先说一遍topic再接着
详述,像B一样直接详述即可;doubled时态错误
D.Of短语无法明确表明expectations的核心内容,应该用同位语从句
E.句式awkward错误同C
1. GWD21-Q1: 非常好的比较题,至今没弄懂,需要再看比较知识点。
答案竟然是E
According to analysts, an a lliance between three major personal computer companies and most of the nation’s largest local telephone companies would enable customers to receive internet data over regular telephone lines with speeds much higher than is currently possible.
A.with speeds much higher than is
B.with speeds that are much higher than are
C.at much higher speeds as are
D.at much higher speeds than that
E.at speeds much higher than are
这里比较的应该是速度。
因为前面的speeds是负数,所以than后面就算知道,也不能用that。
