英語語法是針對英語語言進行研究後,系統地總結歸納出來的一系列語言規則。語法是組詞造句的規則,是把合適的詞放進合適位置的語言(句子)規則,語法可以分成爲兩大部分:分別爲詞法和句法。詞法包括各類詞的形態及其變化,句法主要講句子的種類和類型,句子成分以及遣詞造句的規律。語法的精髓在於掌握語言的使用。
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.
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.
能同時適用於上述兩個句型的'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
雙賓語結構的被動語態: 雙賓語結構變爲被動語態時,可以把主動結構中的一個賓語變爲主語,另一個賓語仍然保留在謂語後面,但多數是把間接賓語變爲主語.
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.
