1、 教学过程被动语态的结构及用法Step 1 Warm-up: Review 复习一、Review the past participle forms of the verbs1、规则动词过去分词的构成：(1)一般情况+ed 如 worked；以不发音的 e 结尾，直接+d 如 liked(2)以“辅音字母+y ”，y i+ed 如 study studied(3)以重读闭音节结尾，词尾仅一个辅音字母，双写词尾辅音字母+ed如 stopped，planned2、特殊变化：课本附录Step 2 Presentation:呈现一、语态概述：略讲1、英语的语态是通过动词形式的变化表现出来的，分为主动语
2、态与被动语态两种。2、主动语态，即主语是动作的执行者。Eg. We clean the classroom.3、被动语态，即主语是动作的承受者。Eg. The classroom is cleaned by us.二、被动语态的构成：略被动语态的基本构成是“助动词 be+及物动词的过去分词+(by)”。be 本身无词义，但有时态、人称和数的变化。by 通常紧跟在被动句谓语动词之后，有时也可省。1、现在：（1）一般现在时 am/is/are + done（2）现在进行时 am/is/are + being done（3）现在完成时 have/has + been done2、过去：（1）一般过去
3、时 was/were + done（2）过去进行时 was/were + being done3、将来：一般将来时 shall/will + be done3、被动语态句式：略（1）肯定：主语+be+过去分词+(by) The cars are made by them.（2）否定：主语+be+not+过去分词+(by) The cars are not made by them.（3）一般疑问句：Be+主语+过去分词+(by) Are the cars made by them?（4）含有情态动词的被动语态：主语+情态动词+(not)+be+ 过去分词+(by)4、被动语态的用法：1、强调动
4、作的承受者 eg. Her bike is stolen.2、淡化动作的执行者（没有说明、没必要指出、不知道）Eg. This coat is made of cotton. 这件大衣是棉制的。3、动作的承受者是谈话的中心 eg. The picture was drawn by a boy under eight.Step 3 Consolidation:巩固5、主动与被动的转换：时态不变A. 主动中的宾语 被动语态的 主语B. 谓语变成被动结构（be 过去分词 ）C. 主动中的主语 被动语态的 宾语（介词 by 之后），主格宾格Eg. He cut down a tree. A tree
5、was cut down by him.1、S+V+O(1)主动句为带 no 的否定句，被动句常用 no，neither ，never 等Eg. No one has ever beaten her at tennis.She has never been beaten at tennis.(2)主动句为带 any 构成不定代词的否定句，被动句常用 noEg. We didnt notice anything special in his work. Nothing special was noticed in his work.2、S+V+O 1+O2（1）主动句的间接宾语/直接宾语 被动句
6、的主语Eg. They gave the children many good books. The children were given many good books.Many good books were given to the children.（2）只能主动句的直接宾语 被动句的主语Eg. She wrote Jim a letter. A letter was written to Jim.（3）宾语从句一般不可作为被动句的主语Eg. She told me when the film started. I was told when the film started.6、被
7、动语态的注意事项：1、by 短语省略的几种情况：（1）无法确定动作执行者 eg. The Great Wall was built thousands years ago.（2）泛指动作执行者 eg. Children should be given a good living.（3）不愿说出动作执行者 （4）前后文对执行者已有暗示 eg. Your homework should be handed in early tomorrow.2、主、被动转化,被保留的间接宾语前还原介词 toforof (give, send, take, bring, get等)3、在被动语态中，感官动词和使役动
8、词后面的不定式要带 to (听 hear, 观 see/watch, 使 make, 让 let, 帮 help)4、没有被动语态的词：happen, rise, fit, turn, taste, sound, smell 等Step 4 Practice:练习1. More and more foreigners speak Chinese in the world now.（改为被动语态）2. Today Chinese _(teach) in many schools around the world.3. Rice is grown in the south by them.（改为主
