动词跟，变过分（过去分词）
原主by后做宾语（可以省略）
代词宾格要记住
1.在主动语态句中动词make、have、let、see、watch、 hear、feel等后接动词不定式作宾语补足语，动词不 定式不加to。 但变成被动语态时后面的不定式都须加上to。
注意
(1) The boss makes them work ten hours a day.
(2) Tom lets his little sister water flowers every day.
→ They are made to work ten hours a day.
→ His little sister is let to water flowers every day by Tom.
主动语态变为被动语态的注意事项：
2. 含有双宾语的句子，主动句中的间接宾语或者直接 宾语都可变为被动语态中的一个主语，另一个保留不变。变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或 for。
常用双宾语的动词：show/give/offer/send /bring/ lend/teach/buy
例如：The teacher gives the pupils some advice.
直接宾语
间接宾语
→The pupils are given some advice by the teacher.
→Some advice is given to the pupils by the teacher.
宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。

不能被动
