16、meeting tomorrow. A meeting is going to be held tomorrow. They are about to shoot the murderer. The murderdr is about to be shot by them.,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. The students listen to the teacher carefully in class. 被动句：The teacher is listened to carefully by the students

17、 in class. e.g. They look after the new students in the school. 被动句：The new students are looked after by them in the school.,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. 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

18、 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，feel，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，sen

19、d, 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 by him everyday. e.g. My mother bought me a computer. 被动1 I was bought a computer by my mother . 被动2 A computer was bought for me by

20、 my mother .,(一)语态转换时要注意的问题 1. 把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。 We have bought a new computer. A new computer has been bought. (正确) A new computer have been bought. (错误) 2. 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多。 My uncle gave me a present on my birthday. I was given a

21、present on my birthday. 如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说： A present was given to me yesterday.,保留宾语,注意：一般在下列动词后，常在间接宾语前用介词 to，如： bring, give, lend, offer, pass, promise, sell, show, teach, tell 等。 The cup with mixture was showed to the class. My bike was lent to her. 一般在下列动词后，间接宾语前用介词 for,
