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 t the teacher carefully in class.被动句:The teacher is listened t carefully by the students in class. e.g. They lk after the new students in the schl.被动句:The new students are lked after by them in the schl.
2.当动词带有复合宾语(有宾补), 并且宾补是省去“t”的动词不定式时,在被动语态中应加上“t” e.g. They make us d all the wrk.被动句:We are made t d all the wrk by them. e.g. We ften hear her sing sngs.被动句:She is ften heard t sing sngs by us. e.g. I saw him walk t schl.被动句:He was seen t walk t schl by me.这些动词真奇怪,主动句中t 离开,被动句中t回 来。( let ,have ,make,feel,see ,watch, hear,ntice…)
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“t”或“fr” 。常见加t的动词有give,send, teach,write, shw, pass, ask, tell…常见加fr的动词有make, draw, buy… e.g. He gives me a flwer everyday. 被动1 I am given a flwer by him everyday. 被动2 A flwer is given t me by him everyday. e.g. My mther bught me a cmputer. 被动1 I was bught a cmputer by my mther . 被动2 A cmputer was bught fr me by my mther .
