使用被动语态时应注意的事项
（1）在动词need，require 和want之后+ding表被动。（可转化为be dne)The rm needs cleaning. The flr requires washing. （2）形容词wrth之后用主动表示被动。 The bk is well wrth reading. （3）含有省略了t的动词不定式的宾语补足语的句子变被动语态，t归位。make sb. d sth. → sb. Be made t d… see sb. d sth → sb. be seen t d…（4）含双宾语的句子变为被动语态：I gave her sme mney. →She was given sme mney. →Sme mney was given t her. He bught her a watch. → A watch was bught fr her. →She was bught a watch.
（1）主动形式表示被动之意的动词多为连系动词，lk, feel, smell，wash等 The flwer smells sweet. The watch lks gd. This bk sells well.（2）不及物动词没有被动式：happen，cst，take place An accident happened yesterday.（3）一般来说，当动词的宾语是动名词或者是不定式时不能变成被动语态。I hpe t d this wrk by myself. D yu like t d sme reading？ （4）动词have不论在什么情况下都不能用于被动语态；reach, leave , enter，turn 等的宾语是表示地点或者是处所时，无被动语态。
