2、was +going to+be+p.p.werehad +been+p.p.注p.p.表示过去分词。(1) 被动语态的用法：不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。如：A man was killed in the accident.(一个人死于事故)/ This window was broken yesterday.(这扇窗子是昨天被打破的)不说或者众所周知是谁做时,用被动语态,省略by短语。如：Rice is also grown in this place.(这个地方也种水稻)/ A railroad will be built here in three
3、years.(三年之后这里将要修建一条铁路)强调动作的承受者,句尾加by短语。如：It was written by Lu Xun.(它(书)是鲁迅写的)/ A pet dog is never killed by its owner.(宠物狗是不会被主人宰杀的)(2)主动语态如何改写为被动语态：主动句：主语(人/物) + 谓语(及物动词) + 宾语(人/物) + 其他 + 状语 (动作的执行者) (各种时态形式) (动作的承受者) 被动句：主语(人/物) + 谓语(及物动词) + by +人 / 物 + 其他 + 状语 (动作的承受者) (be +过去分词) (动作的执行者) (3) 注意点
4、：“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。如：His teacher gave him a dictionary.He was given a dictionary by his teacher.(老师给他一本字典他得到老师一本字典)也可以用直接宾语做被动句的主语,但是需用to或者for引出原句的间接宾语。如：His teacher gave him a dictionary.A dictionary was givento him by his teacher.(老师给他一本字典一本字典由老师送给了他)/His father made him a kite.A
5、kite was madefor him by his father.(他的父亲给他做了一个风筝一个风筝由他的父亲做给了他)“动词+宾语+动词原形”改为被动时,动词原形前要加to.如：The boss made the poor man work 12 hours a day.The poor man was madeto work 12 hours a day.(老板让这个可怜的人一天工作12小时这个可怜人被迫一天工作12小时)“动词+介词”改为被动时,介词一般在原位不动。如：The girl takes good care of her little brother.The girls l
6、ittle brother is taken good care of by her.(女孩照顾小弟弟女孩的小弟弟由她照顾着)“be+过去分词”未必表示被动语态,而可能是系表结构。如：He is pleased / worried / tired /.(系表)(他高兴/焦虑/疲劳)Hewas hit / knocked down / told / shot / .(被动)(他被击中/撞倒/关照/射中)7、动词的非谓语形式：动词不做谓语时的固定形式。(1)动词的非谓语形式包括动词不定式、动名词和分词三种形式；其中分词又包含现在分词和过去分词两种形式。它们在句子中不能单独作谓语。(2)动词不定式：
7、形式：动词不定式基本形式由“不定式记号to+动词原形”构成。它的否定形式只要在“to”前面加上“not”。它的疑问形式是：“wh-疑问词+to+动词原形”。*它的被动形式：“to be +过去分词”。*它的完成形式：“to have +过去分词”。动词不定式具有名词、形容词和副词的特征,即可以在句子中作主语、宾语、定语、状语、表语和宾语补足语。但不定式也保留动词的某些特征,即不定式后面可以跟宾语、表语和状语。动词不定式加上相关成分就构成不定式短语。动词不定式可以放在谓语前句子作主语。但是通常将作主语的动词不定式或不定式短语放在谓语后面,而在主语位置用“it”作形式主语(有时在不定式的前面还会用
8、for sb.表示不定式的逻辑主语)。如：To help animals is helping people.(帮助动物就是帮助人)/ It is very difficult (for us) to learn Chinese well.(对于我们而言)学好汉语是非常的困难)/ It took me half an hour to work out this problem.(解出这道题花了我一个小时的时间)动词不定式可以作谓语动词(及物动词)的宾语。A 及物动词+不定式一般形式：谓语动词(vt.)+不定式(作宾语)说明want(想) / try(试图) / decide(决定) / wou

13、e internet?(你能教我怎样上网吗？)C 不定式作宾语而后面又有宾语补足语时,通常用it代替作形式宾语,而不定式则后置。如：I found it not very easy to learn to ride a bike.(我发现学骑车不很容易)动词不定式可以在句子中用作定语,放在名词或代词后面。A 记住下面的一些结构：被修饰部分 + 不定式(作后置定语)汉语意思a keyto lock the door锁门的钥匙 a boxto hold these things装这些东西的箱子give her a bookto read给她一本书读Is there any (+名词/代词)to (
