初中英语语法——动词的语态讲解动词的语态知识梳理：提纲挈领，抓住重点和难点！英语动词有两种语态，即主动语态（The Active Voice）和被动语态（The Passive Voice）。
主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者，例如：Many people speak English . (主动语态)English is spoken by many people. (被动语态)1、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。
助动词be 有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。
被动语态的肯定式、否定式及疑问式列表如下：肯定句：主语+ be+ 过去分词 +（by…） eg. He is often asked to do this work (by his boss).否定句：主语+ be not +过去分词 +（by…） eg. I am not invited to the party (by him).一般疑问句：Be + 主语+过去分词+ （by…）？ eg. Are your clothes washed by yourself?特殊疑问句：疑问词+ be+主语 +过去分词+ （by…）？ eg. What is this sweater made of?现以动词give为例，其被动语态的各种时态如下：3、被动语态的用法：1）当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者时，或者只需强调动作的承受者时，要用被动语态。
例如：This jacket is made of cotton.English is spoken in many countries in the world.2）强调动作的承受者时。
如：The boy was saved at last.这个男孩最后得救了。
3）主动语态变被动语态的步骤:主动句: The boy broke the window yesterday.被动句: The window was broken by the boy yesterday.步骤一：原句中的宾语the window变成主语。
步骤二：谓语动词broke改为被动形式：was broken步骤三：原句中的主语The boy放在介词by的后面。
步骤四：其他成分如：yesterday不变。
5) 有两个宾语的句子的被动语态：A. 可有两种被动语态的常用动词有：buy，give，leave，lend，offer，pay，teach，tell，show，等。
