2024年12月英語四級語法入門知識必須具備：動詞

動詞

時態

1)目前完成進行時態: 動作或狀況從過去某時開始,繼續到目前,可能繼續下去,也會剛剛結束.

I’ve been writing letters for an hour.

I’ve been sitting in the garden.

2)過去完成進行時: 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)以后完成進行時: 以后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)以后完成時: 以后某時已發生的事.

I shall have finished this one before lunch.

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

語態

可以有兩種被動結構的種類,比如:

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一般都是表示“估計”,“相信”等意義的動詞,容易見到的有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總是表示不一樣的意義.比如:

Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit.

雙賓語及賓補結構的被動語態

雙賓語結構的被動語態: 雙賓語結構變為被動語態時,可以把主動結構中的一個賓語變為主語,另一個賓語仍然保留在謂語后面,但多數是把間接賓語變為主語.

He was asked a number of questions at the press conference.

Two days were allowed them for making the necessary preparations.

賓補結構的被動語態:

She was called Big Sister by everybody.

Then he was made a squad leader.

He was considered quite qualified for the job.

The room was always kept clean and tidy.
