问题描述:

I used to earn_____than a pound a week when I first started work.
A.a little B.a few C.fewer D.less
我选的是C,请问为什么?我就知道表示金钱,距离,重量和时间的词组一般谓语用单数.此题a pound表示金钱【一英镑】那为什么还选D呢?pound这个词前有不定冠词修饰是不是就变成可数名词了?快给俺讲讲吧?

pound本身就是可数名词.看这个例子
I bought a car for five hundred pounds.
我花500英镑买了一辆小汽车.
less than 是固定习惯搭配,意思是“少于”
