在英语中,不同时间里发生的动作或存在的状态,谓语动词要用不同的形式来表示,谓语动词的这种不同形式称为动词的时态。

英语中有8种基本时态,其中4种现在时态,对应4种过去时态。4种现在时态是:一般现在时态;现在进行时态;一般将来时态;现在完成时态。他们对应的4种过去时态是:一般过去时态;过去进行时态;过去将来时态;过去完成时态。

12-9 时态的呼应

在含有从句的复合句中,主从句的时态要求遵循一定的规则,既保持协调,又相互照应。

1.主句和宾语从句的时态呼应

(1)在含有宾语从句的复合句中,主句是现在时态或将来时态时,宾语从句的谓语动词可用所需要的任何适当的时态。如:

I think Tom is ill today.我认为汤姆病了。(主句一般现在时,从句一般现在时)

I think Tom has gone to the doctor's.我认为汤姆已经去看医生了。(主句一般现在时,从句现在完成时)

I think Tom went to the doctor's yesterday.我认为汤姆昨天去看医生了。(主句一般现在时,从句一般过去时)

(2)当主句的谓语动词是过去时,宾语从句中的谓语动词也要用过去的某种时态。如:

Mr.Smith told me that he would come to our school.史密斯先生告诉我他要来我们学校。(主句一般过去时,从句过去将来时)

Mr.Smith told me that he didn't know the news.史密斯先生告诉我他不知道那个消息。(主句一般过去时,从句一般过去时)

Mr.Smith told me that he had known the news already.史密斯先生告诉我他已经知道那个消息了。(主句一般过去时,从句过去完成时)

注意:

如果从句叙述的是客观真理或不可改变的事实,虽然主句用了过去时态,但从句仍用一般现在时。如:Mr.Smith told me that children under 18 in his country cannot buy alcohol.史密斯先生告诉我在他的国家18岁以下的孩子不能买酒。

2.主句与状语从句的时态呼应

在含有时间状语从句和条件状语从句的复合句中,从句用一般现在时,主句要用一般将来时,祈使句或含有情态动词的句子。如:

You'll make progress if you keep working hard.如果你继续努力你就会取得进步。

Don't get off the bus until it has stopped.直到车停稳再下车。

3.主句与定语从句的时态呼应

在含有定语从句的复合句中,主句的时态有时也决定从句的时态。如果主句的时态是现在时态,从句可根据实际需要确定时态,如果主句用了过去时态,定语从句一般也用过去时态。如:

This is the person I met yesterday.这就是昨天我遇见的那个人。

This is the person who will give us a lecture tomorrow.这就是明天要给我们作报告的那个人。

This was the person who would give us a lecture the next day.这就是第二天要给我们作报告的那个人。
