英語四級語法必備知識點
動詞(時態,語態,用法,省略,一致性等)
時態
1)現在完成進行時態 (have/has been + -ing 分詞構成): 動作或狀態從過去某時開始,繼續到現在,可能繼續下去,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): 將來某時已發生的事.

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:

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.

賓補結構的被動語態:

短語動詞

Vt + adv + O (無被動語態)

Vt + O + prep

在以as, than, when, if, unless等引導的從句中的省略:
在有些狀語從句中,如果謂語包含有動詞be,主語又和主句的主語一致a),或者主語是it b),就常常可以把從句中的主語和謂語的一部分(特別是動詞be)省略掉.
