新概念1第143-144被动语态中的特殊情况1.不及物动词带介词和介词宾语时，在变为被动语态时，仍然要带上介词。e.g.Thestudentslisten

totheteachercarefullyinclass.被动句：Theteacherislistenedtocarefullybythestudentsinclass.e.g.Theylookafterthenewstudentsintheschool.被动句：Thenewstudentsarelookedafterbythemintheschool.新概念1第143-144

2.当动词带有复合宾语(有宾补),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.Theymakeusdoallthework.被动句：Wearemadetodoalltheworkbythem.e.g.Weoftenhearhersingsongs.被动句：Sheisoftenheardtosingsongsbyus.e.g.Isawhimwalktoschool.被动句：Hewasseentowalktoschoolbyme.这些动词真奇怪，主动句中to离开，被动句中to回来。（let，have，make，feel，see,watch,hear,notice…)新概念1第143-1443.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.Hegivesmeaflowereveryday.

被动1Iamgivenaflowerbyhimeveryday.

被动2Aflowerisgiventomebyhimeveryday.e.g.Mymotherboughtmeacomputer.
