被动语态(精品课件).ppt

变化口诀： 宾变主来, 主变宾; 谓变 be done, 时不变; 注意数格，抄其余。 Exercises: 1) They play football on Sunday. 2) Lucy does the homework in the evening. Exercises: They built the tall building last year. He took good care of his little brother yesterday. Exercises: We will have a sports meeting next week. Children will take some photos in the schoolyard tomorrow. 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。(动词后的介词不可省） e.g. The students listen to the teacher carefully in class. 被动句：The teacher is listened to carefully by the students 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”。（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 　　　　 练习： 1.Many people speak English. 2.They made computers in the U.S.A. 3.People used knives for cutting
