do像have一样可用做普通动词,这时它就与do和did连用来构成一般现在时和一般过去时的肯定式和疑问式:
I do not do do you do? dont you do?
he does not do does he do? doesnt he do?
I did not do did you do? didnt you do?
等do可以用在进行式或一般式中:
what are you doing(now)?
Im doing my homework.
(现在)你在做什么?
我在做家庭作业。
Whats he doing tomorrow?
他明天要做什么?(最近将来)
What does he do in the evening?
他平时晚上做什么?(习惯)
Why did you do it?
I did it because I was angry.
你是为什么这么干的?
因为当时我生气。
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。
两位先生这时都说:
How do you do?
您好。
原先这是问候对方健康的话,现在仅用为介绍场合中的公式化的问候语。
do的其他用法如:
He doesnt do what hes told.
他不按照告诉他的去做。(不服从命令)
What do you do for a living?
Im an artist.

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:
Its nothing to do with you.相当于:
It doesnt concern you.
这跟你没关系。
