一般过去时的被动语态
1.—Whenwasthecarinvented?
—Itwasinventedin1885.
——汽车是什么时候发明的?
——它是在1885年被发明的。
由例句可以总结出,一般过去时的被动语态的结构:
2.Wasitinventedin1885?
它是在1885年被发明的吗?
一般疑问句的构成是将 提前。
3.Whoweretheyinventedby?
它们是由谁发明的?
Whenwasthecarinvented?
汽车是什么时候发明的?
思考:
其特殊疑问句的构成是:
主动语态如何变被动语态?
特殊情况:
(1)(含有双宾语的句子变被动语态)
剖析:
含双宾语的主动语态的句子变为被动语态时,常把那个指人的间接宾语变为被动语态的主语;也可把那个指物的直接宾语用作主语,但此时必须在间接宾语前加上介词to或for。
如:
Hegavemeabook.
→Iwasgivenabookbyhim.(人作主语)
→Abookwasgiventomebyhim.(物作主语)
Myfatherboughtmeabike.(变被动语态)
→ (主语是人)
→ (主语是物)
(2)感官动词和使役动词在主动句中其后的动词不定式不带to,但变被动句时必须加上to。
如:
Thebossmadeherworkfor16hoursaday.
→Shewasmadetoworkfor16hoursaday.
