一般现在时被动语态课件.ppt
Module2语法精讲一般现在时的被动语态,英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：Many people speak Chinese.谓语：speak的动作是由主语many people来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people.主语English是动词speak的承受者。,Grammar,被动语态的构成：be+Pp(动词的过去分词)人称、数和时态的变化是通过be的变化表现出来的。一般现在时被动语态的构成：am/is/are+Pp+(by+动作执行者)例如：Children love this song.(主动语态）（动作执行者）（动作承受者）This song is loved by children.(被动语态）（动作承受者）（动作执行者）,主动语态变被动语态口诀：宾语提前主语变，原主变宾by后见，时态人称be关键。,把下列的句子变为被动语态的句子1、They speak English in Canada.2、People use wood for making tables.3、They make computers in the USA.4、They grow rice in South China.,English is spoken(by them)in Canada.,Wood is used(by people)for making tables.,Computers are made(by them)in the USA.,Rice is grown(by them)in South China.,看谁最准确,把下列句子变成被动句：More and more people speak English.2.We plant more trees every year here.3.Dalian produces big ships.4.Farmers grow rice in summer.5.We clean our classroom every day.,English is spoken(by more and more people).,More trees are planted(by us)every year here.,Big ships are produced in Dalian.,Rice is grown(by farmer)in summer.,Our classroom is cleaned(by us)every day.,被动语态的用法：,1、当我们不知道动作的执行者时；A book is stolen.2、当我们不必提出动作的执行者时；I was born in 1990.3、当我们强调或侧重的是动作的接受者时。She is liked by everybody.,句型转换,1.The girl looks after the old woman well.The old woman by the girl.2.We often keep our classroom clean.Our classroom us.3.Some people throw waste paper everywhere.Waste paper everywhere.4.Daming beats his brother.His brother.5.The police catches a thief.A thief the police.,is looked after well,is kept clean by,is thrown,is beaten by Daming,is caught by,Quiz,English _(speak)by many people.Tea _(grow)in Southeast China.Many trees _(plant)in North China.The brush _(make)of bamboo and animals hair.Confucius _(know)as a great thinker in China.,is spoken,is grown,are planted,is made,is known,1 Shakespeare/see/as a wonderful writerShakespeare is seen as a wonderful write.2 his plays/know/all over the worldHis plays are known all over the world.3 Shakespeare s works/still love/by millions of peopleShakespeares works are still loved by millions of people.4 his plays/turn into/wonderful filmsHis plays are turned into wonderful films.5 Shakespeare s plays/teach/in our schoolShakespeares plays are taught in our school.6 we/ask/perform one part of Shakespeare s playsWe are asked to perform on part of Shakespeares plays.,Quiz:Rewrite the sentences,Look at the pictures and the notes.Use the notes to describe how a book is made.,Homework,Do exercises book.(Page 13-15),Thank you!Goodbye!,
