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”。(即:主动省to,被动加上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 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。(常考词有:make,see,hear,feel,watch,notice 等。),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,send,teach,write,show,pass,ask,tell 常见加for的动词有:make,buy draw,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 my mother.,4.系动词没有被动形式,主动形式表被动意义。常见的有taste(尝起来),sound(听起来),feel(摸起来),look(看起来),smell(闻起来)等.例如:1)The apple tastes good.2)The song sounds gentle.,5.有些动词如:sell(卖),wash(洗),write(写)等与副词well(好),easily(容易地)等连用,描绘事物的特性,用主动表被动。例如:1)The coat washes easily.2)The books sell well,Homework:1.He cleans the classroom everyday.2.They finished their
