一、修饰可数名词的常用修饰语有these, those, few, a few, many, a good [great] many, a great [good] number of 等：

Few people would agree with this. 很少人会同意这种看法。

He has a great many friends here. 他在这儿有很多朋友。

注：a good [great] many 后直接跟名词，不用介词of。但是，若其后所接名词有the, these, my 等限定词修饰，则要用介词of：a great many of my friends 我的朋友当中的许多人

二、修饰不可数名词的常用修饰语有this, that, little, a little, a bit of, much, a great deal of, a large amount of 等：

I have little time to do it. 我没什么时间来做此事。

He didn’t give me much money. 他没给我很多钱。

A great deal of money is spent on research. 研究工作上花了许多钱。

注：在现代英语中，a great amount of 后有时也接可数名词，但有许多语法学家反对，学生最好避免使用。

三、有些修饰语既可修饰可数名词也可修饰不可数名词，如all, some, enough, a lot of, lots of, plenty of, a (large) quantity of 等：

You needn’t hurry. There’s plenty of time. 你不必着急。时间多着哩。

There are plenty of men out of work. 失业的人很多。

We need a quantity of baskets. 我们需要一批篮子。

He put a small quantity of sugar in the milk. 他在牛奶中放了少量的糖。

四、有些名词形式上是复数，但却被用作不可数名词，使用much, little等修饰语：

He hasn’t got much brains. 他没什么头脑。

He took much pains to do the work. 他费了不少心做这工作。

I said I wouldn’t want much wages. 我说过我不要很多工资。

It's high time you were taught a little manners. 该是你学一点礼貌的时候了。

背诵才是硬道理，坚持背诵，必定收获良多。
