When drive-ins were at the height of their popularity in the late 1950's, some 4000 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 我觉得可以先把D,E排除，明显表述不符合语法规则，然后可以把A排除，因为是可数的，在B,C之间就没主意了。。。最后答案是C，但是我很怀疑，因为我觉得amount似乎也有表示不可数的意思，有没有大牛明白的？谢谢！作者: perain 时间: 2011-7-18 16:53

从笔记里面摘出来的：
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。
