一般现在时的被动语态 (Page 36) 1. 被动语态的含义

在英语中有两种语态,即主动语态(The Active Voice)和被动语态(The Passive Voice)。 含义 例句 Many people speak English.许多人讲英语。 被动语态 主语是动作的承受者,即行为动作的对象 2. 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、时态和数的变化。

3. 被动语态的用法:当说话者不知道动作的执行者或没有必要指出动作的执行者时,只需要强调动作的承受者,可以使用被动语态。如果需要在被动语态中指出动作的执行者时一般用介词by引出。 ?Chinese is spolen by the largest number of people in the world. 汉语是世界上为最多人所讲的语言。 4. 一般现在时的被动语态

(1)一般现在时的被动语态的构成:在一般现在时态的句子中,被动语态由"be(am/is/are) + 及物动词的过去分词"构成。助动词be随人称、数的变化而改变。

?This knife is made of wood and metal. 这把刀是用木头和金属制造的。 ?Bananas are produced in Hainan. 香蕉产于海南。

(2)主动语态改写成被动语态的方法:将主动句的宾语变成主语,将主动句的谓语变成 "be + 及物动词的过去分词",主动句的主语变成被动句中by的宾语(或省略)。

说明 谓语speak这一动作是由主语many people来执行的 主动语态 主语是动作的执行者 English is spoken by many 主语English是speak这一动作people.英语被许多人讲。 的承受者 主动句:主语 + 谓语 + 宾语

被动句:主语 + be + 及物动词的过去分词 + by + 宾语

Most middle school students play football. 主语 谓语 宾语

Football is played by most middle school students.大部分中学生踢足球。

【警示】如果主动句中有两个宾语(直接宾语和间接宾语),可以把其中任意一个变成被动句的主语。 My teacher gives me a lot of books.(主动语态) 我的老师给我许多书。 主语 谓语 间宾 直宾

被动语态:I am given a lot of books by my teacher. 被动语态:A lot of books are given to me by my teacher. (3) 一般现在时的被动语态的句式变化:
