[求助][讨论]GWD-21-13没有解决的问题！

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.

1. there are less than one-quarter that many
2. there are fewer than one-quarter as many
3. there are fewer than one-quarter of that amount

4. the number is less than one-quarter the amount
5. it is less than one-quarter of that amount

1. one-quarter the amount我认为是正确的表达，我们可以说 twice the size, 为什么不能说one-quarter the amount？

1. one-quarter the amount我认为是正确的表达，我们可以说 twice the size, 为什么不能说one-quarter the amount？

2.amount在ETS看来可数不可数呢？我们以前学的amount是不可数的

3.one-quarter as many 就是 one-quarter of that number的意思?

看到曾有个MM这样说的，求证是否正确

三分之一的电脑

one third of computers

one third of adults

one-quarter of Economic growth

as many:The same number of

For example, He changed jobs four times in as many years means he changed jobs four times in four years.

amount一般作不可数，只有在表示sum时可数

Ding,

看了一下所有关于这个题的帖子，主要是B与C的选择。那位NN给个说法，都快考了！！我开始选的C,但是想到amount用于不可数名次，那就只能选b了！！但是觉得b读起来别扭。

 one-quarter the amount应是the one-quarter amount

 one-quarter is adj
