a little ,few ,a bit ,a few 后面加可数还是不可数?

little 修饰不可数名词,few 修饰可数名词.
little 和 a little的区别在于 little 表示否定,就是说没有的意思； a little 表示肯定,指有一些,但是数量很少.
例如：There is little water in the bottle.瓶子里没有水.
There is a little water in the bottle.瓶子里有一些水.
few 和 a few 的区别于little 和 a little一样.
例如：There are few animals in this area.这个区域没什么动物.
There are a few animals in this area.这个区域有一些动物.
a bit 不能直接接名词,它可直接接形容词,如果接名词要在名词前加of 即可修饰可数名词也可修饰不可数名词,但是它后面及时接可数名词那也是接可数名词的单数形式.
例如：
This girl was a bit strange.这个女孩有点儿古怪.
They're worth quite a bit of money.它们值不少前.
This comes as a bit of a disappointment.这有点儿让人失望.

a little 不可数
few 可数
a bit 不可数
a few 可数
