1、主动语态 被动语态,8种主动语态的演变 1. 一般现在时 一般过去时： V或V-es V-ed He studies English He studied English思考：这两种时态有什么关系？,am/is /are +v-ing &n
2、bsp; was/were+v-ing They are making model planes. They were making model planes思考：这两种时态有什么关系？,2.现在进行时 过去进行时,will+V would+Vam/is /are going to +V was/were going to +V &nbs
3、p; He will repair his bike tomorrow Eg: He would repair his bike the next day We are going to pick apples We were going to pick apples 思考：这两种时态有什么关系？,3.一般将来时 过去将来时,have / has + v-en &nbs
4、p; had + v-en He has already repaired his bikeEg: He had already repaired his bike大家通过观察，找到8种主动语态时态结构的变化规律了吗？,4.现在完成时 过去完成时,把谓语中的第一个词变为过去式，则这种时态可以由现在时或将来时变为其相应的过去时态.即：1.一般现在时 &nb
5、sp;一般过去时 v/v-es v-ed2.现在进行时 过去进行时 am/is /are+v-ing was/were+v-ing3.一般将来时 过去将来时 will+v would +v am/is /are going to +v was/were going to +v4.现在完成时
6、;过去完成时 have/has+v-en had +v-en,小结：时态变化规律,首先，我在这里引入一个虚动词的概念 英语中除了实意动词之外还有系动词be，助动词do/does/have/has，情态动词must/can/may等，它们常常用来帮助我们变句，我们就叫它们虚动词吧！ 被动语态的基本结构为be+v-en，主动语态变为被动语态是有规律的，即：1挪：虚动词照挪（注意：am/is/are可互换；was/were可互换；have/has可互换）2仿：把be仿写成与原
7、实义动词相同的形式3变：不管原实义动词是什么形式，一律变成过去分词,1挪，2仿，3变.被动语态就是这么简单,基本方法：主动语态的宾语用作被动语态的主语，谓语遵循1挪，2仿，3变，原主语做by的宾语，They speak English English is spoken by them(本主动句中无虚动词，则1挪省略；2仿,把be仿写成与原实义动词相同的形式则为is，3变，把speak变成spoken)He is listening to music
8、; Music is being listened to by him 1挪 2仿 3变,1挪，2仿，3变 的应用,1 He studies English every day.2 He studied English last night.3 They are making model planes now.4 They were making model planes this time yesterda
