do/ does/ have/ has可以做助动词吗？

Question

如题所述

Answer 1

可以的。do/does/have/has 都是常见的助动词。

【1】 do/does 用于一般现在时。其中does 用于第三人称单数。

Do you like it?

I don't like it.

Does she like it?

He doesn't like it.

【2】have/has 用于现在完成时。其中has用于第三人称单数。

Have you finished it?

I haven't finished it.

He hasn't finished it.

Has she gone?

希望帮到你。

Answer 2

首先这四个词都是实义动词，do/does意为“做”，have/has意为“有”助动词
但更重要的是它们做助动词的用法：do/does是一般现在时态的助动词，用于构成否定句或疑问句，如：I
get
up
early
in
the
morning
.~(否)I
do
not
get
up
early
...~(疑)Do
you
get
up
...(does用于第三人称，基本同do)
have/has是完成时态的标志，后接动词的过去分词，如：I
have
finished
my
homework
.
