We use quantifiers when we want to give someone information about the number of something: how much or how many.
我們用數(shù)量詞告訴別人數(shù)量的多少。

Sometimes we use a quantifier in the place of a determiner:
有時(shí)候我們用限定詞來(lái)描述：

Most children start school at the age of five.

We ate some bread and butter.

We saw lots of birds.

We use these quantifiers with both count and uncount nouns:
以下的限定詞可描述可數(shù)和不可數(shù)名詞：

and some more colloquial forms:
有些比較口語(yǔ)化：

Some quantifiers can be used only with count nouns:
有些只能用來(lái)描述可數(shù)名詞：

and some more colloquial forms:

Some quantifiers can be used only with uncount nouns:

有時(shí)候遇到比較抽象的詞我們用數(shù)量詞來(lái)形容：

Members of groups

You can put a noun after a quantifier when you are talking about members of a group in general…
當(dāng)提到一般的群體成員時(shí)，用數(shù)量詞修飾名詞。

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
但是如果提到一個(gè)特殊群體的人或事物，也用the來(lái)修飾名詞。

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，當(dāng)我們提到兩個(gè)人或者事物時(shí)，我們用both、either和neither修飾名詞。

*Nouns with either and neither have a singular verb.
Either和neither修飾名詞，動(dòng)詞用單數(shù)形式。
