6、内容:一. 被动语态 1. “语态表示主语和谓语动词之间的关系。英语中有“两态的说法,即主动语态和被动语态,本单元中反复出现的should be allowed 就是一个含有情态动词(should)的被动语态。 先看几个根本概念 主语是动作的发出者为主动语态 主语是动作的接受者为被动语态 只有及物动词才有被动语态。 2. 被动语态的构成 (1)请大家看图 The office is cleaned every day . The office was cleaned yesterday. Compare active and passive: 动作的接受者the office成了句子的主语,就
7、应该用被动语态。从上面的例句我们可以总结: 一般现在时的被动语态为:主am / is / are (not)过去分词 一般过去时的被动语态为:主was / were 过去分词 如:Butter is made from milk. This house was built 100 years ago. 以前我们学过的was / were born 生于,就是一个被动语态 born是个过去分词(bear) When were you born I was born in 1989. 如果要特别强调动作或行为的执行者,句子后面需接by ,译为“被(由) 如:We were woken up by
8、a loud noise . 我们被嘈杂的声音吵醒。 (2)请看图 从上面例子,我们可以看出,现在进行时被动语态的构成为 主语is / am / are + being 过去分词 再如: My car is being repaired now. Some new houses are being built near the park. 公园附近在建一些房子。 (3)请看图 BEFORE NOW 从上面例子,我们可以看出现在完成时被动语态的构成为 主语have / has been 过去分词 如: My key has been stolen. My keys have been stole
9、n. I am not going to the party , I havent been invited. 含有情态动词的被动语态 情态动词be过去分词 A note had better be left to him. Teenagers should be allowed to wear their own clothes 这里我们列举了几个主要时态,那么其它时态呢? 一般将来时 主语will be 过去分词 过去将来时 主语would / should + be 过去分词 过去进行时 主语was / were + being 过去分词 过去完成时 主语had + been +过去分词
10、 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。 归纳: 肯定句:主语be + 过去分词(by ) 否认句:主语be not 过去分词(by ) 一般疑问句:Be 主语过去分词(by ) 特殊疑问句:疑问词be主语过去分词(by ) 3. 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,不用by动作执行者短语 Such books are written for children. 这些书是为儿童写的。 I havent been told about it . 没有人告诉我这件事 (2)强调动作的承受者,这时应用by短语。 T
11、he cup was broken by David. (3)作客观说明时,常采用一种被动语态句型 Its / was said / believed / reported / + that Its reported that about three hundred people were killed in this earthquake. 据报道,这次地震中大约有三百人死亡。 4. 主动语态变为被动语态 把主动语态的句子变为被动语态的方法是: (1)把原句中的宾语变为主语 (2)动词改为被动形式,即be+过去分词 (3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。 本卷须知
12、: 主动语态变成被动语态应本卷须知 从主动语态到被动语态的过程中主语、谓语动词、宾语都发生变化。 注意主格与宾格的变化形式。 注意主语的人称及数的变化对be动词带来的影响。 注意be动词的时态形式取决于原主动语态的动词时态形式。 5. 被动语态的几种类型 (1)有两个宾语的句子的被动语态(直接宾语,间接宾语) 常见的接双宾语的动词有 通常这种句子可以改为以“人当主语;和以“物当作主语的两种被动语态。 如:He gave me a book. I was given a book by him. (以I做主语) A book was given to me by Tom. (以物book作主语)
13、 He teaches us English. We are taught English by him. (以人当主语) English is taught us by him. (以物作主语) (2)含有宾语补足语的句子的被动语态 keep, make 三类的动词常常有宾语补足语,在被动语态中,宾语补足语位置不变。 We keep food fresh in the fridge. 主 谓 宾 宾补 Food is kept fresh in the fridge. I saw him go into the office building. He was seen to go into the office building. 英语中有“十大动词的说法,即feel , hear , listen , have , make , let , look , watch , see , notice ,这些词在主动句中,其后
