英语被动语态讲解
英语动词有两种语态:主动语态和被动语态。
主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。
一、被动语态的构成
英语动词的被动语态由助动词be+及物动词的过去分词构成。助
动词be必须与主语的人称和数量保持一致,并有时
态的变化。例如:The man was
fooled by the two boys. The book has been
translated into several languages.
二、被动语态的用法
(1)动作的执行者不知道是谁或难以说明时常用被动语态。例如:
Street lights are often turned on at six in
winter. The new test book will be used next
term.
(2)当动作的承受者比起动作的执行者来说更能引起人们的关心而需要加以强调时,要用
被动语态。例如:
This kind of bicycle is not sold in
our shop. The thief was caught by a policeman
yesterday.
(3)含有双宾语的句子,主动句中的间接宾语或者直接宾语都可变为被动语态
中的一个主语,另一个保留不变。变为
主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to
或for。
例如:The pianist gave the pupils(间接宾语)some
advice(直接宾语)
→The pupils were given some
advice by the pianist. →Some advice was given to
the pupils by the pianist.
(4)在主动语态句中动词make、ha
ve、let、see、watch、hear、feel等后接动词不定式作宾语补足语,动词不定式不加to
。
但变成被动语态时后面的不定式都须加上to。
例如:The boss made
them work ten hours a day. →They were made to
work ten hours a day.
A boy saw him
enter the house. →He was seen to enter
the house.
三、被动语态的时态
教材中出现了四种时态的被动语态及带有情态动词的被动语态。
一般现在时
构成:助动词be + 动词的过去分词 例如:This kind of car is made
in shanghai.
一般过去时 构成:助动词waswere +
动词的过去分词 例如:The bridge was built in 1992.
现在进行时 构成:be + being + 动词的过去分词 例如:A
new bridge is being built in my hometown.
一般将来时 构成:willbe going to do + be + 动词的过去分词
例如:These books are going to be posted tomorrow.
带有情态动词的被动语态 构成:情态动词 + be + 动词的过去分词
例如:Can this walkman be repaired here?
※主动语态改为被动语态的步骤:
①主动语态中的宾语变为被动语态句中的主语;
②主动语态句中的动词改为相应的被动语态;
③主动语态句中的主语变为被动语态句中by的宾语。
主动语态句中的谓语动词带有双宾语,即直接宾语和间接宾语时,转换方法有两种:
①把间接宾语转化为主语,保留直接宾语
②把直接宾语转化为主语,保留间接宾语。此时,一
般需在间接宾语前加适当的介词(通常是介词for或to)。
在短语see sb. do
sth. 中,动词see后跟不带to的不定式作宾补。改为被动语态时要加上to。用于这一结构的谓语动词
一般是表示知觉的动词如see, hear,watch,find等,以及使役动词make,
let等。
