1.修饰可数名词的：
many,few,a few,a couple of,several,a large/small number of=large/small numbers of,a good/great many=many a+名词单数, a large/small quantity of=large/small quantities of.
2.修饰不可数名词的：
much,a great deal of,little,a little,a large/small sum of(一般修饰钱的数量）,a large/small amount of,a bit of.
3.可数和不可数都可以用的：
some,any,plenty of,a lot of=lots of,a large/small supply of=large/small supplies of.
还有一点容易混淆也爱考的：
a little,a bit 的区别..
1.a little 和a bit 都可跟不可数名词 但A little 是直接跟的 而a bit 需要加of的： 譬如说：a little/a bit of water/money.
2.a little 常修饰些不好的形容词 譬如说 sad,difficult,cold,silly等.而 a bit 褒贬都可以 .
3.not a bit是“一点也不”的意思 not a little是“不是一点点”
