初中英语主动语态变被动语态的句子练习题和答案.doc

? 被动语态 一、语态概述 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。如：Many people speak English. 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。所谓“被动语态”，相当于中文中常说的“被……”、“由……”的句式，如：“他的自行车被偷了。”，再如：English is spoken by many people. 主语English是动词speak的承受者。 判断：看下面的两个例句，你来判断哪个是主动哪个是被动？ He opened the door.他开了门。 （____________） The door was opened.门被开了。 （____________） 二、被动语态的构成: be动词+Vp.p 被动特点强调宾，用be加上过去分。行为对象作主语，逻辑主语by来引。 1. English is ___________（speak）in Canada. 2. The blouse is ___________（make）of silk. 3. English is ___________（speak）by many people. 谁做的动作不知道，说出谁做的没必要。动作承受者需强调，用被动语态莫忘了。 1. Some stamps were ___________（steal）last week. 2. The PRC was ___________（found）on October 1, 1949. 3. Football is ___________（play）in most middle schools. 被动语态须留意，P.P前面助动be. be + P.P am（is,are）现在时，am（is,are）+P.P was和were表过去。was（were）+P.P 完成have（has）been。have（has）been+P.P 将来，情态，be原形。will（can,may,must）be+P.P 进行时态两个be，前表时态后加ing。am（is,are）+being+P.P 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。凡是汉语中带“被”的句子，都能转换成英语的被动语态。 三．几种常用时态的被动语态—— 1.一般现在时： am/is/are+过去分词 肯定句：Bikes are ___________（sell）in that shop. 否定句：Bikes are not sold in that shop. 疑问句：Are bikes sold in that shop?
