[初中]全新英語(yǔ)語(yǔ)法12-9 時(shí)態(tài)的呼應(yīng)

在英語(yǔ)中，不同時(shí)間里發(fā)生的動(dòng)作或存在的狀態(tài)，謂語(yǔ)動(dòng)詞要用不同的形式來(lái)表示，謂語(yǔ)動(dòng)詞的這種不同形式稱為動(dòng)詞的時(shí)態(tài)。

英語(yǔ)中有8種基本時(shí)態(tài)，其中4種現(xiàn)在時(shí)態(tài)，對(duì)應(yīng)4種過(guò)去時(shí)態(tài)。4種現(xiàn)在時(shí)態(tài)是：一般現(xiàn)在時(shí)態(tài)；現(xiàn)在進(jìn)行時(shí)態(tài)；一般將來(lái)時(shí)態(tài)；現(xiàn)在完成時(shí)態(tài)。他們對(duì)應(yīng)的4種過(guò)去時(shí)態(tài)是：一般過(guò)去時(shí)態(tài)；過(guò)去進(jìn)行時(shí)態(tài)；過(guò)去將來(lái)時(shí)態(tài)；過(guò)去完成時(shí)態(tài)。

12-9 時(shí)態(tài)的呼應(yīng)

在含有從句的復(fù)合句中，主從句的時(shí)態(tài)要求遵循一定的規(guī)則，既保持協(xié)調(diào)，又相互照應(yīng)。

1.主句和賓語(yǔ)從句的時(shí)態(tài)呼應(yīng)

（1）在含有賓語(yǔ)從句的復(fù)合句中，主句是現(xiàn)在時(shí)態(tài)或?qū)?lái)時(shí)態(tài)時(shí)，賓語(yǔ)從句的謂語(yǔ)動(dòng)詞可用所需要的任何適當(dāng)?shù)臅r(shí)態(tài)。如：

I think Tom is ill today.我認(rèn)為湯姆病了。（主句一般現(xiàn)在時(shí)，從句一般現(xiàn)在時(shí)）

I think Tom has gone to the doctor's.我認(rèn)為湯姆已經(jīng)去看醫(yī)生了。（主句一般現(xiàn)在時(shí)，從句現(xiàn)在完成時(shí)）

I think Tom went to the doctor's yesterday.我認(rèn)為湯姆昨天去看醫(yī)生了。（主句一般現(xiàn)在時(shí)，從句一般過(guò)去時(shí)）

（2）當(dāng)主句的謂語(yǔ)動(dòng)詞是過(guò)去時(shí)，賓語(yǔ)從句中的謂語(yǔ)動(dòng)詞也要用過(guò)去的某種時(shí)態(tài)。如：

Mr.Smith told me that he would come to our school.史密斯先生告訴我他要來(lái)我們學(xué)校。（主句一般過(guò)去時(shí)，從句過(guò)去將來(lái)時(shí)）

Mr.Smith told me that he didn't know the news.史密斯先生告訴我他不知道那個(gè)消息。（主句一般過(guò)去時(shí)，從句一般過(guò)去時(shí)）

Mr.Smith told me that he had known the news already.史密斯先生告訴我他已經(jīng)知道那個(gè)消息了。（主句一般過(guò)去時(shí)，從句過(guò)去完成時(shí)）

注意：

如果從句敘述的是客觀真理或不可改變的事實(shí)，雖然主句用了過(guò)去時(shí)態(tài)，但從句仍用一般現(xiàn)在時(shí)。如：Mr.Smith told me that children under 18 in his country cannot buy alcohol.史密斯先生告訴我在他的國(guó)家18歲以下的孩子不能買酒。

2.主句與狀語(yǔ)從句的時(shí)態(tài)呼應(yīng)

在含有時(shí)間狀語(yǔ)從句和條件狀語(yǔ)從句的復(fù)合句中，從句用一般現(xiàn)在時(shí)，主句要用一般將來(lái)時(shí)，祈使句或含有情態(tài)動(dòng)詞的句子。如：

You'll make progress if you keep working hard.如果你繼續(xù)努力你就會(huì)取得進(jìn)步。

Don't get off the bus until it has stopped.直到車停穩(wěn)再下車。

3.主句與定語(yǔ)從句的時(shí)態(tài)呼應(yīng)

在含有定語(yǔ)從句的復(fù)合句中，主句的時(shí)態(tài)有時(shí)也決定從句的時(shí)態(tài)。如果主句的時(shí)態(tài)是現(xiàn)在時(shí)態(tài)，從句可根據(jù)實(shí)際需要確定時(shí)態(tài)，如果主句用了過(guò)去時(shí)態(tài)，定語(yǔ)從句一般也用過(guò)去時(shí)態(tài)。如：

This is the person I met yesterday.這就是昨天我遇見的那個(gè)人。

This is the person who will give us a lecture tomorrow.這就是明天要給我們作報(bào)告的那個(gè)人。

This was the person who would give us a lecture the next day.這就是第二天要給我們作報(bào)告的那個(gè)人。
