2.被动语态需要注意的几个方面:(1)在主动句中,使役动词make，let，have,感官动词see，hear，feel，watch，notice等后接省略to的动词不定式作宾语补足语，在变成被动语态时,后面的不定式需加上“to”。eg:Mymothermakesmegetupearlyeveryday.=Iammadetogetupearlyeverydaybymymother.(2)有些词,如系动词taste,feel,look,sound等常用主动语态表达被动的意思。eg:Thevoicesoundsnice.一般过去时态的被动语态

2.被动语态需要注意的几个方面:(3)主动语态的句中若有双宾语,变被动语态时，可将间接宾语(人）变为被动句的主语,而把直接宾语（物）留作被动句的宾语；或把主动句的直接宾语变为被动句的主语。此时间接宾语前常用介词for或to等来连接。eg:Heboughtmeabook.=Iwasboughtabookbyhim.=Abookwasboughtformebyhim.(4)有些动词，如happen,belong等没有被动语态。eg:Thebikebelongstome.这辆自行车属于我。
