18、),并且宾补是省去“to”的动词不定式时，在被动语态中应加上“to”e.g.They make us do all the work.被动句：We are made to do all the work by them.e.g.We often hear her sing songs.被动句：She is often heard to sing songs by us.e.g.I saw him walk to school.被动句：He was seen to walk to school by me.这些动词真奇怪，主动句中to 离开，被动句中to回来。（let，have，make，fee

19、l，see,watch,hear,notice)3.当动词带双宾语时(一个宾语是指人，一个是指物)，将其中指人的宾语提前作被动句的主语时，另一个宾语按顺序照抄下来；如是将指物的宾语提前作被动句的主语，在被动句中则指人宾语前应加“to”或“for”。常见加to的动词有give，send,teach，write,show,pass,ask,tell常见加for的动词有make,draw,buy e.g.He gives me a flower everyday.被动1 I am given a flower by him everyday.被动2 A flower is given to me b
