巧记一, 二,三,轻松学被动

被动语态是历年来中考的考点之一。在学习被动语态时,一定要彻底地弄明白,搞清楚。再认真审题,相信能够百战百胜。那么,如何更容易地了解和掌握被动语态呢?请牢记一变二套三注意”。

一变
变主动为被动或变被动为主动时 ,把原句的主语和宾语互换,注意被动语态的构成“be + 过去分词”。如:We grew a tree yesterday. A tree was grown yesterday by us.

二套
被动语态的构成为“be + 过去分词”。在不同的时态中,过去分词保持不变,而be动词随着时态有不同的变化,如:
am/ is/ are(一般现在时);was/ were (一般过去时);have/ has been( 现在完成时)am/ is/are being (现在进行时)等。若含有情态动词,则用“情态动词+ be + 过去分词”结构。
例如:The flowers are being watered by them. 他们正在浇花。
The plan has been found by me. 钢笔已经被我找到了。
Homework must be finished first. 必须要先完成作业。

三注意
句中含有双宾语如give/ buy sb sth 时,一般要把间接宾语(sb)变成被动句的主语,若将直接宾语( sth ) 变成主语,则在间接宾语前加上介词tofor。常用to的介词有give, show, pass, hand, lend, send 等;常用介词for 的动词有borrow, buy, make 等。
如:The eraser was passed to me at last. 最后,橡皮被传递给了我。
A new toy was bought for me as my birthday present by him.
他给我买了一个玩具,作为我的生日礼物。
主动句中,谓语是含有介词或副词的动词短语,变为被动句时,介词或副词不能省略。常见的词组有listen to, take care of, pay attention to 等。
如: We often talk with the old politely.
→The old are often talked with politely by us.
主动句中作宾补的不带to的动词不定式,变被动时要加上to.常见的词组有hear/ see sb do sth, make sb do sth 等。
如:we make the boy stand outside.
→The boy was made to stand by us.
