英语的语态是通过动词形式的变化表现出来的。
主动语态表示主语是动作的执行者。
例如:Many people speak English. 主语people是动词speak的发出者。
被动语态表示主语是动作的承受者。
例如:English 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“be+及物动词的过去分词”构成。
不及物动词本身没有被动语态。
人称、数和时态的变化是通过be的变化表现出来的。
三、各种时态被动语态的构成1.一般现在时:am/is/are+动词过去分词 Cars are made by them.2.一般过去时:was/were+动词过去分 The MP3 was bought by my father.3.含有情态动词的被动语态,由“情态动词+be+过去分词”构成,例如: we can repair this watch in two days.→This watch can be repaired in two days.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.把主动语态的谓语变为被动语态的谓语。
3.把主动语态的主语变为被动语态的by短语。
(① by短语可以省。
② by短语后跟代词的宾格。
)主变被解题步骤1. 划分句子成分,找宾语 ----即动作的承受者2. 判断宾语的单复数 ----即be动词的单复数.3. 判断动词的时态 ----即be动词的时态.4. 修改谓语的形式 ----即原句动词改为过去分词5. 修改原句的主语 ----即by+ 宾语(原主语).(宾变主,主变宾,谓动变成be done 形,人称、数、格随着变)五、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。
Some new computers were stolen last night. (不知道电脑是谁偷的)(2)强调动作的承受者,而不强调动作的执行者。
The window was broken by mike.窗户是迈克打破的。
