We use quantifiers
when we want to give someone information about the number of something: how much or how many.
Sometimes we use a quantifier in the place of a determiner

We use these quantifiers with both count and uncount nouns:
Some quantifiers can be used only with count nouns:
and some more colloquial forms:
Some quantifiers can be used only with uncount nouns:
And, particularly with abstract
nouns such as time, money, trouble, etc, we often use:
Members of groups
You can put a noun after a quantifier when you are talking about members of a group in general…
Few snakes are dangerous.
Both brothers work with their father.
I never have enough money.
…but if you are talking about a specific group of people or things, use of the … as well
Few of the snakes are dangerous.
All of the children live at home.
Note that, if we are talking about two people or things we use the quantifiers both, either and neither:注意，当我们提到两个人或者事物时，我们用both、either和neither修饰名词。
*Nouns with either and neither have a singular
