(3.含有復合賓語的主動結構變被動結構時,通常將賓語變為被動句的主語,而賓語補足語就成為主語補足語。注意:省略to的不定式作賓補時,不定式符號to必須補上。例如:
Someone saw him swim in Qianling Lake yesterday.(變被動
He ______ ______ ______ swim in Qianling Lake yesterday.
(4.不定式的被動結構:動詞不定式的被動語態為“to be +過去分詞”。例如:
The radio says a wild animal zoo is to ______ in our city.
A.be building
B.build
C.be built
D.built
5.以疑問代詞開頭的疑問句轉換成被動句時要注意詞序:應將主動句中的疑問代詞改為介詞by的賓語,但仍然放在句子開頭。例如:
Who has broken the cup?(改為被動語態)
→By whom has the cup been broken?
E.注意區別
被動語態和過去分詞作表語的區別:
1)含義不同:被動語態強調動作,重點說明動作由誰完成、怎樣完成;而過去分詞作表語通常用來描寫情景,敘述人或事物的特征及所處的狀態。試比較:
The window is broken.窗子破了。(系表結構)
The window is broken by him.窗子被他打破了。(被動語態)
2)用法不同:過去分詞作表語時可以被 so,very,too等程度副詞修飾,而被動語態則不能用so,very,too修飾,而需用much,very much,so much,too much修飾。試比較:
He was very interested in science.他對科學有極大興趣。(系表結構)
I was so much surprised at the scene that I didn t know what to do.我被那種場面搞得大吃一驚,不知所措。(被動語態)
F.牢記(相關)句型
初中教材中與被動語態相關的句型有:
1.be covered with被……覆蓋
2.be made of由……制作(發生物理變化)
be made from由……制作(發生化學變化)
be made in由(某地)制造
be made by被(某人)制造
3.be used for被用來……
be used as被當作(作為)……來使用
be used to do sth.被用來做某事
4.It is said that...據說……
It is hoped that...希望……
It is well known that...眾所周知……例如:
①—Your coat looks nice.Is it ______ cotton?
—Yes.It s ———— Shanghai.
A.made of;made by
B.made of;made in
C.made for;made by
D.made for;made in
② This machine is used ______ the room wet.
A.for keeping
