do像have一样可用做普通动词,这个时候它就与do和did连用来构成一般目前时和一般过去时的一定式和疑问式:
I do not do do you do? don't you do?
he does not do does he do? doesn't he do?
I did not do did you do? didn't you do?
等do可以用在进行式或一般式中:
what are you doing(now)?
I'm doing my homework.
(目前)你在干什么?
我在做家庭作业。
What's he doing tomorrow?
他明天要干什么?(近期以后)
What does he do in the evening?
他平常晚上干什么?(习惯)
Why did you do it?
I did it because I was angry.
你是为何这么干的?

How do you do?是经过介绍之后双方互致的问候语:
Hostess:Mr Day,may I introduce Mr Davis?Mr Davis, Mr Day.
女主人:戴先生,让我来介绍戴维斯先生。这位是戴维斯先生,这位是戴先生。
两位先生这个时候都说:
How do you do?
你好。
原先这是问候他们健康的话,目前仅用为介绍场所中的公式化的问候语。
do的其他使用方法如:
He doesn't do what he's told.
他不根据告诉他的去做。(不服从命令)
What do you do for a living?

to do with(只限于动词不定式)有有关系的意思。主要用于 it is/was something/nothing to do with+名词/代词/动名词结构:
It's nothing to do with you.等于:
It doesn't concern you.
这跟你没关系。
