各種時態(tài)的被動語態(tài)
被動語態(tài)概述
被動語態(tài)的概念:它是動詞的一種形式,表示主語與謂語之間的執(zhí)行或被執(zhí)行關(guān)系。主動語態(tài)表示主語是謂語動作的執(zhí)行者,例如:They saw the little boy crying by the river. 被動語態(tài)表示主語是謂語動作的承受者,例如:The little boy was seen crying by the river.
被動語態(tài)的構(gòu)成
被動語態(tài)的形式是由“助動詞be+動詞的過去分詞”構(gòu)成。助動詞be隨著主語的人稱、數(shù)、時態(tài)等的不同而變化。幾種常見時態(tài)的被動語態(tài)形式如下:
1. 一般現(xiàn)在時 am/is/are + 過去分詞
例如:Rice is planted in the south of China.
2. 一般過去時 was/were + 過去分詞
例如:These trees were planted the year before last.
3. 一般將來時 will/shall + be + 過去分詞
例如:A sports meeting will be held next week in our school.
4. 現(xiàn)在進行時 am/is/are + being + 過去分詞
例如:Your radio is being repaired now.
5. 過去進行時 was/were + being + 過去分詞
When he got there, the problem was being discussed.
6. 現(xiàn)在完成時 have/has + been + 過去分詞
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.
7. 過去完成時 had + been + 過去分詞

虛擬條件句的倒裝
虛擬條件句的從句部分如果含有were, should, 或had, 可將if省略,再把were, should或had 移到從句句首,實行倒裝。
Were they here now, they could help us.
=If they were here now, they could help us.
Had you come earlier, you would have met him
=If you had come earlier, you would have met him.
Should it rain, the crops would be saved.
=Were it to rain, the crops would be saved.
注意:
在虛擬語氣的從句中,動詞'be'的過去時態(tài)一律用"were",不用was, 即在從句中be用were代替。
If I were you, I would go to look for him.
如果我是你,就會去找他。
If he were here, everything would be all right.如果他在這兒,一切都會好的。
