语法:被动语态
(一)概念:英语中动词有两种语态: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。
主动句:Many people speak Chinese. 被动句:Chinese is spoken by many people .
(2) 构成:被动语态由“be+动词的过去分词”构成, be有人称、数和时态的变化。
(3) 变化方法:宾变主,主变宾,谓语动词be+分(过去分词),by短语动后随。
1)一般现在时:am/is/are +动词过去分词
2)一般过去时:was/were+动词过去分词
3)一般将来时:will be+动词过去分词 am/is/are going to be +过去分词
4)含情态动词:情态动词+be+过去分词
(四)带双宾语句子的被动语态:一般把间接宾语sb变为被动语态的主语,则另一个不动。如把直接宾语sth变为被动语态的主语则需在间宾前加 for 或 to。加to的有give, pass, show, send, offer, lend等;加for的有buy, cook, make(制作)等。
如:1.He gave me a book. -I was given a book by him. -A book was given to me by Tom.
2. I bought him a book. -He was bought a book by me. -A book was bought for him by me.
(五)在主动语态中省去to 在变为被动语态时应补出来。
即hear , watch , see , make , let , have, notice这些词在变被动句时必须加to.
如:1.I saw him play basketball last Sunday. --He was seen to play basketball last Sunday.
2.The boss made him work 10 hours every day. --He was made to work 10 hours every day.
(六)主动结构表示被动含义:
1) look, smell, sound, feel, taste等作连系动词用时,主动形式表被动意义。
如:The old woman looks worried.
2) write, read, sell, wash, open等常和表示行为方式的状语连用表达效果和程度时, 用主动表被动。
如:This pen writes well. 这笔很好用。 This book sells well. 这书很畅销。
3) 动词 need, want, require等接动名词作宾语构成主动结构表被动含义。
need doing=need to be done 如:His shoes needed repairing. 他的鞋需要修理。
(七)其他
1.只有及物动词(可直接跟宾语的动词叫及物动词)才能有被动语态。 happen, rise无被动
2.系动词不能用于被动语态。(seem, become, get, grow, turn, remain, stay)
3.表示度量的动词不能用于被动语态。(weigh) 如:This panda weighs 100 kilos.
4.某些短语动词用作不及物动词也不能用于被动语态。(take place发生, set out出发, come true实现, come out出版, belong to属于 )
如:His new book comes out every week. 他的新书每周出版。
A lot of changes have taken place in my hometown. 我的家乡已经发生了很多变化。
5.表示某些状态的及物动词如fit, cost 也不能用于被动语态。
如:The shirt doesn't fit me. 这件衬衫不适合我。
