1.如果句子里有谓语动词(不包含助动词) , 则把程度副词放在主谓之间

结构:主语 程度副词 调语动词

【例如】

Tom usually goes to work by car.

汤姆通常开车去上班。

Mary often asks me for help.

玛丽经常向我求助。

2.放在be动词之后

结构:主语 be 程度副词

【例如】

Tom is often late.汤姆经常迟到。

Anne isn't usually sick.安妮通常不会生病。

Peter isn't always right.

彼特并非永远正确。

注意:如果我们把程度副词放在省略句中,则该结构不成立。

【例如】

Is she usually on time?

她通常都准时吗?

Yes, she usually is.是的,她通常都是。

She never is.她从不是。

口语中还有其他的习惯表达,也不必要遵循上述结构。

【例如】

What are you doing here? Shouldn't you be at school?

你怎么在这儿?你不应该在学校吗?

I normally am at school at this time, but my teacher is ill.

通常这时候我应该在学校,但是老师生病了。

3.如果句中有多个动词(包含助动词) , 则把程度副词放在谓语结构的第一个动词之后

结构:主语 助动词或情态动词 程度副词 主动词

【例如】

I can never remember his name.

我总是记不住他的名字。

Anne doesn't usually smoke.

安妮通常不吸烟

The children have often complained about the playground facilities.

孩子们经常抱怨游乐场设施。

但在have to句型中存在例外。

结构:主语 程度副词 have to 主动词

【例如】

We often have to wait for the bus.

我们经常要等公车。

She never has to do any housework.

她从不需要做家务。
