a little,a little bit,a bit以及kind of,kinds of的用法,

我再补充点：a little 后还可以跟可数名词，此时little表示小的，小可爱的。如：
she is a little girl.
所以a little后面跟不可数名词和可数名词时，a little的意义是不同的。后跟不可数名词译为：（量）少的；后跟可数名词译为：小的（可爱）的。
希望能帮助你

1.a little=a little bit 修饰形容词或副词,例：He is a little(a little bit )thin.So he runs a little (a little bit )slowly.另：此两个短语还可用来修饰名不可数名词.
2.a bit 用来修饰名词,同时后要加of,例：I want a bit of bread.
3.kind of意为有点,相当于a little,多用来修饰形容词,也可修饰动词,例：She was kind of shy.But she kind of hoped to be invited.
4.kinds of 意为各种各样的,相当于various,例:There are kinds of flowers in the garden.
