126 do用做普通动词

 

dohave一样可用做普通动词,这时它就与dodid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                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

do可以用在进行式或一般式中:

what are you doingnow)?

I'm doing my homework

―(现在)你在做什么?

―我在做家庭作业。

What's 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?

How do you do?是经过介绍之后双方互致的问候语:

HostessMr Daymay I introduce Mr DavisMr 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 doesn't do what he's told

他不按照告诉他的去做。(不服从命令)

What do you do for a living

I'm an artist

―你是做什么工作的?

―我是个画家。

How's the new boy doing

to do with(只限于动词不定式)有“有关系”的意思。主要用于 it iswas somethingnothing to do with+名词/代词/动名词结构:

It's nothing to do with you.相当于:

It doesn't concern you

这跟你没关系。
