被动语态教案.doc

1、英语被动语态复习皇宫镇中心学校：张丽教学目标：语言学习的最终目的是运用，因此本节课的核心目标是：学生能够在听、说、读、写的各种语言综合实践活动中熟练运用一般将来时被动语态。具体目标如下：（1）语言知识目标：了解八大时态的被动语态的结构，掌握其用法。（2）语言技能目标：能够在听、说、读、写的各种语言综合实践活动中熟练运用被动语态，并能应用于现实生活。（3）情感态度目标：学习兴趣，探究精神；合作精神。（4）学习策略目标：学会总结所接触语言材料中的语言规律并加以应用的方法。教学重点：了解英语各时态的被动语态，尤其是一般现在时、一般过去时、一般将来时、现在完成时、情态动词这些时态的被动语态要熟练掌握。

2、教学难点：用被动语态熟练造句。课前准备：教师：课件 学生：搜集关于被动语态的复习资料Step 1: Explanation(1) 被动语态的概念（1）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. 英语English是动词speak的承受者。(2) 被动语态的构成被动语态由“助动词be及物动

3、词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以speak为例说明被动语态在各种时态中的构成。一般现在时：amis/arespoken 一般过去时：waswerespoken 一般将来时：willshall bespoken现在进行时：amisare beingspoken过去进行时：was/were beingspoken现在完成时：havehas beenspoken过去完成时：had been + spoken(3) 被动语态的用法a. 不知道或没有必要说明动作的执行者是谁。例如：Some new computers were stolen last night.

4、一些新电脑在昨晚被盗了。（不知道电脑是谁偷的）This bridge was founded in 1981.这座桥竣工于1981年。b. 强调动作的承受者，而不强调动作的执行者。例如：The glass was broken by Mike.玻璃杯是迈克打破的。 This book was written by him.这本书是他写的。Your homework must be finished on time.你们的家庭作业必须及时完成。(4) 主动语态变被动语态的方法1. 把主动语态的宾语变为被动语态的主语。2. 把谓语变成被动结构（be过去分词）（根据被动语态句子里的主语的人称和数，以

5、及原来主动语态句子中动词的时态来决定be的形式）。3. 把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：All the people laughed at him.He was laughed at by all people.They make the bikes in the factory.The bikes are made by them in the factory.He cut down a tree.A tree was cut down by him.(5) 含有情态动词的被动语态含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成， 例如：My
