被动语态复习一 主动语态和被动语态的转换:主： I + learn + English被：English + is learned + by me .谓语动词带双宾时，既可将间接宾语转化为主语，也可以讲直接宾语转化为主语。若将间接宾语转化成主语，则保留直接宾语；若将直接宾语转化成主语则在间接宾语前加上介词to或for。eg：She gave me a book. I was given a book. A book was given to me.主动句中在感官动词see, hear, watch, feel, notice 等及使役动词let, make, have等跟省略to的不定式，变为被动句时应加上不定式符号to。eg：He makes the girl stay at home. The girl is made to stay at home. Last Sunday we heard them sing Peking Ope
