Much/Many/A lot of中文意思都是“很多”，都可以修饰名词，

我们重点从两点区别它们：

1.它们修饰的是可数名词还是不可数名词。

Much+不可数名词（uncountable noun）

e.g.: I haven’t got much luggage.

How much money do you want?

注：haven’t 是“have+not”的缩写

Many+可数复数名词（plural noun）

e.g.: I don’t know many people.

Did you buy many books?

A lot of +不可数名词 或者 可数复数名词

上面的句子除了特殊疑问句都可以用”A lot of “ 代替：

e.g.: I haven’t got a lot of luggage.

I don’t know many people.

Did you buy a lot of books?

2.它们可以用在什么句型中？

Much 用在疑问句和否定句中，很少用在肯定句。

e.g.: Do you drink much coffee?

(一般疑问句)

How much money do you have？

（特殊疑问句）

I don’t drink much coffee.

(否定句)

Many 和 A lot of通常什么句型都可以用。

但“A lot of ”不和How连用，而“Much”和“Many”可以 。

e.g.: Have you got many/a lot of friends?

(一般疑问句)

We haven’t got many/a lot of friends.

(否定句)）

How many friends have you got?

（特殊疑问句）

I got many/a lot of friends.

（肯定句）

另外，Much和 A lot of后面还可以不带名词。

e.g.: I don’t like him very much.

We like movies so we go to cinema a lot.
