例. Good care must ______ babies particularly while they are ill.
A. take B. take of
C. be taken D. be taken of
答案 D。

被动语态用法
2)可带双宾语的动词的被动,如give, send, take, bring, teach, tell, offer, sing, buy, promise, make, write, ask, lend, show, pay

3) 动词主动表被动:
系动词:feel, look, sound, smell, taste, prove, turn out to be等+ 形容词/名词.
Ice feels cold.
The news proves to be/ turns out to be true.
表示主语属性的词: sell, wash, read, wear, write, clean, shut, start, open等,不单独使用,常加修饰语well, easily, smoothly等.

被动语态常考点
4) 在描写属性的形容词后,句子主语是不定式逻辑上的宾语,因此往往认为形容词后省略了for somebody, 不定式用主动形式。常见形容词有:hard, difficult, easy, heavy, fit, good, comfortable, convenient, impossible等。
The problem is easy to do.
The question is difficult to answer.
The box is heavy to carry.
The project is impossible to complete in a year.
比较:The problem is to be done./The question is to be answered.
注意:
没有形容词时,虽然不定式与主语是动宾关系,但必须用被动式。
被动语态常考点
5) 使役动词(make/let/have)和感官动词(see, watch…)带有复合宾语,变为被动语态时,需要还原在主动语态中省略了的不定式符号to。
I hear the girl sing English songs.
→ The girl is heard to sing English songs.
被动语态常考点
例:The workers were made ________ ten hours a day.
A. work B. to work
C. working D. worked
总结:
主动语态 → make/let/have/see/hear sb do sth
被动语态→ sb be made/let/had/seen/heard to do sth
被动语态常考点
6) want, need, require, deserve 和be worth等词的后面可以用动名词的主动形式doing表示被动意义。
The table wants cleaning.
The children needs looking after.
The coat requires mending.
