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.
there are less than one-quarter that many
there are fewer than one-quarter as many
there are fewer than one-quarter of that amount
the number is less than one-quarter the amount
it is less than one-quarter of that amount
请看讲解视频
注意：however 、 then 、 therefore 、 in addition 都是副词不作连词用
"twice as many", "one-quarter as many", etc. are not only acceptable as idiomatic expressions but also extremely common in the english language.
since this idiom is present in the correct answer, which was written by gmac, IT IS CORRECT.
amount修饰不可数名词
(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
(B) Correcet；补全省略即there are fewer than one-quarter as many (as there were in the late 1950s)； fewer修饰可数名词正确；
(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；
(E) it没有指代对象，that amount指代4,000 drive-ins错。
"amount" is a construction that can only be used to refer to UNCOUNTABLE quantities -- Ron
'...some 4,000 existed...' implied 比的应该是#（可数）-> fewer 可数 排除A/D/E
可数# 跟 amount 不能比 【amount->often times 描述不可数object(i.e. liquid...) ] 排除C

(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 in the late 1950s)； fewer修饰可数名词正确；
(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。
太厉害了！！！问一下b选项为什么后面全都可以省略啊。。。看着结尾as many 我都直接排除这选项了 真的头大
好清楚！借用了
B补全省略即 there are fewer than one-quarter as many (as there were in the late 1950s)
few修饰可数名词，less修饰不可数
amount修饰不可数

amount修饰不可数名词
as many=a number that is equal to another number
examples:
- They say the people of Los Angeles speak 12 languages and teach just as many in the schools.
- A great trip! We visited five countries in as many days.
the earlier part of this sentence already mentions the # of drive-ins in the u.s. in the 1950's, so it is not stated again. since it is not stated as part of an actual parallel construction, you don't need the second "as".
amount-->不可数名词
amount只能用在不可数名词上
要注意number和amount指代的不是一件事。number指代的是数字，amount指代的是数。在这道题中，number指代的是4000这类的数字，amount指代的是数量。
想骂人；误选A；因为感觉B 哪有fewer than as这种奇怪的搭配
1. fewer and less区别
2.amount 不可数
补充 as many 的用法
1. 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。
那有木有as much？？如果d
换成1/4 of that number或者as much？
感谢
非常感谢！厉害厉害厉害

所以朗文的意思是as many可以当作名词词组是吗
超级赞！！！

1. A错在用了less，语义上是less drive－ins，可数名词，应该用fewer。句子里的there are用了复数和less不可数，以及后面that many用了可数－－都不协调
2. CDE错在amount－只能用在不可数例如continuous quantities／mass nouns，例如water，furniture。RON说C的amount改为number就是正确的。
3. B正确。as many意为一样多。常用为 as many as。。表示平行，但当句子在这个结构之前已经陈述过那个比较的数字的时候，就不需要一定要as many asXXX，这样反而是累赘redundancy。as many表达有：twice as many, one-quarter as many等等表示与两倍一样多，与四分之一一样多，句子中肯定前面已经表达过与XXX的quantity一样多了，所以可以这么使用。
(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。
(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。
number不能多或者少，也不能和amount比
和double的用法相似，此处为非数字物体 用as many
求讲解~
老师这题能不能完整讲讲呀？实在是想不明白。。。
