初中英语句型分类知识点详解：双重被动句

　　1. 将来进行时 2. 现在完成进行时 3. 将来完成进行时 4. 过去完成进行时

　　3)被动句中by后接 us, you, them, one时，by短语可以省略。

　　4)祈使句中使用被动式谓语很少见，以下各句可说是例外：Please be seated. Be trusted rather than feared.

　　一般情况使用let帮助构成祈使句的被动语态。

　　Do one thing at a time. Let one thing be done at a time. Give him something to eat. Let something to eat be given (to) him. /Let him be given something to eat.

　　5)在下列情况下，主动句不能转换成被动句。1. 由于宾语的性质不用被动句：

　　A. 当宾语是缺乏实义的代词it时，不能变，如：walk it, go it, fight it out

　　B. 当宾语为反身代词时，不能变，如: (错) Himself was absented by him.

　　C. 宾语前若有主语的物主代词时，不能变，如: (错) His finger is cut by him.

　　D. 当宾语是each other或one another时不能变，如: (错) Each other is helped by us.

　　E. 当宾语是不定式时，很少转用于被动句。不宜说：To go is wanted by me或It is wanted by me to go.

　　2. 由于某些动词的性质不用被动句, 这类动词有：become, befit, fail, last, resemble, suit, suffice, wish, disappear, lack want, like, hate, possess, own, contain, have, happen to, belong to, break out, take place, set sail, shake hands with, take part in等。
