2016年6月英語四級考試《語法》知識詳解5

Ⅰ動詞(時態(tài),語態(tài),用法,省略,一致性等)

時態(tài)

1)現在完成進行時態(tài) (have/has been -ing 分詞構成): 動作或狀態(tài)從過去某時開始,繼續(xù)到現在,可能繼續(xù)下去,也可能剛剛結束.

I’ve been writing letters for an hour.

I’ve been sitting in the garden.

2)過去完成進行時(由had been ing分詞構成): 過去某個時刻以前一直在進行的動作

I’d been working for some time when he called.

We had been waiting for her for two hours by the time she came.

3)將來完成進行時: 將來某個時刻以前一直在進行的動作.

By next summer, he will have been working here for twenty years.

In another month’s time she’ll have been studying here for three years.

4)將來完成時(由shall/will have 過去分詞構成): 將來某時已發(fā)生的事.

I shall have finished this one before lunch.

They’ll have hit the year’s target by the end of October.

語態(tài)

可以有兩種被動結構的類型,例如:

He was said to be jealous of her success.

It was said that he was jealous of her success.

能同時適用于上述兩個句型的主動詞通常都是表示“估計”,“相信”等意義的動詞,常見的有assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等.

It is supposed that the ship has been sunk.

The ship is supposed to have been sunk.

擔當be supposed to 與不定式的一般形式搭配時往往表示不同的意義.例如:

Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你應該曉得速度限制)

雙賓語及賓補結構的被動語態(tài)

雙賓語結構的被動語態(tài): 雙賓語結構變?yōu)楸粍诱Z態(tài)時,可以把主動結構中的一個賓語變?yōu)橹髡Z,另一個賓語仍然保留在謂語后面,但多數是把間接賓語變?yōu)橹髡Z.
