as much as表示数量的两种用法
一、表示具体的数量
其后通常接有具体数量，其意为“……之多”“多达”“整整”，强调“多”。如：
In fact it cost me as much as 100 dollars. 事实上，它整整花了我100美元。
We walked as much as 50 miles that day. 那天我们整整走了50英里。
She trained hard for the race, sometimes running as much as 60 miles a week. 为了比赛，他拼命地训练，有时一个星期要跑60英里。
—Is it hot up there? 那上面热吗？
—Of course, as much as 45 degrees. 当然热，高达45度。
The speed can vary by as much as 15per cent. 其速度的差别可高达15%。
注：如上例所示，as much as 用于表示具体的数量时，其后接的可能是可数名词，但由于它们意义上仍然为不可数，故用as much as，不用as many as。如100 dollars，尽管其中的dollars为可数名词的复数形式，由于100 dollars仍是一个不可数的概念，仍是不可数的。但是下面这句是错的：I read as much as 100 articles today. 因为这里的100 articles表示的是可数概念，故应改为：I read as many as 100 articles.
二、表示模糊的数量
其意为“与……一样多”，有时much后可接被修饰的名词(不可数)。如：
I ate as much as I could. 我能吃多少就吃了多少。
I’ll spend as much as necessary. 需要花多少钱，我就花多少钱。
Give me as much as you gave Jane. 给我的要和你给简的一样多。
I haven’t got as much money as I thought. 我不像原来想象的有那么多钱。
I'm sorry I haven't done as much as I should. 我很抱歉，我做得很不够。
Some of the doctors are paid almost twice as much as the nurses. 有些医生所获得的报酬差不多是护士的两倍。
We can take as much as our buyer can supply. 买主能提供多少我们就能要多少。
If you charge as much as that, you’ll scare customers off. 如果你要价那么高，你会把顾客吓跑的。
