关于英语语态讲解与精练一、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.主语 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：am / is / are+spoken一般过去时： was / were+spoken一般将来时：will / shall be+spoken现在进行时：am / is / are being+spoken过去进行时：have / has been+spoken现在完成时：have / has been+spoken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 bridge 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"仍要保存.We can repair this watch in two days.This watch can be repaired in two days.They should do it at once.It should be done at once.六、特...
