1、初中英语语法： 动词八种时态、被动语态详解练习及答案：一、初中英语被动语态用法小结1一、语态概述 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。二、被动语态的构成被动语态由“助动词be及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化
2、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三、被动语态的用法（1）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.一些新电脑在昨晚被盗了。（不知道电脑是谁偷的）This brid
3、ge was founded in 1981.这座桥竣工于1981年。（2）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。四、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
4、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.五、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，原来带to的情态动词变成被动语态后“to”仍要保留。We can repair this
