As soon as是英语中常见的一个短语,意思是“一……就……”,as soon as连接的时间状语从句中,指未发生的动作,规律是:主句一般将来时,从句用一般现在时代替一般将来时。

as soon as的用法归纳总结

1、as soon as引导时间状语从句当主句用一般过去时时,从句中用一般过去时或过去完成时。

2、as soon as可以表将来的事:这时主句用一般将来时,从句用一般现在。(主将从现)

3、当主句用一般将来时时,可以用一般现在时代替一般将来时。

as soon as后面用什么时态

两种情况

1、语句表将来:主句用将来时,as soon as引导的从句用一般现在时。

2、语句表过去:主句和从句都要用过去时态。

例句

表将来:

1、I will tell him the news as soon as he comes back home.

等他回来,我就把这个消息告诉他。

2、As soon as Tony finishes his homework , he can play with us.

只要托尼完成了作业,他就可以跟我们一起玩了。

表过去:

1、He got married as soon as he graduated.

他一毕业就结婚了。

2、As soon as I told her my name, she clammed up.

我把我的名字告诉她后,她就什么也不说了。

as soon as等引导的时间状语从句介绍

as soon as意为“一……就……”,引导时间状语从句。

如:

Please call back as soon as you arrive school.请你一到学校,就给我回电。

I’ll write to you as soon as I get there.

我一到那儿就给你写信。

As soon as I went in, Tom cried out with pleasure.我一进门,汤姆就高兴的叫起来。

as soon as引导的时间状语从句前后时态搭配:

(1)主句为一般将来时,从句用一般现在时表示将来。例如:

SHe will come to my home as soon as she gets to tianjin.她一到天津就来我家。

(2)主句为一般过去时,从句也用一般过去时。

例如:

SHe took out her English book as soon as she sat down.她一坐下,就拿出她的英语书。

as soon as引|导时间状语从句意为'一…就…',其主从句的时态,也遵循'主将从现'原则。

e.g. I will tell you as soon as he comes back.他一回来我就告诉你。

下面的连词引导的时间状语从句,都遵循'主将从现'原则:when,while,after,as,until.

e.g. They will never let you know until it happens.

直到事情发生了,他们才会让你知道。

When I grow up, I'll be a nurse and look after the patients.

当我长大后,我要当一名护士去照顾病人。
