情态动词所表示的情态有：请求、命令、允诺、可能、需要、敢于、愿望、义务、能力等2．情态动词本身有词义，但词义不完全，不能单独用作谓语，没有人称和数的变化，且后面只跟动词原形。

如：她会唱英文歌曲。

She cans sing an English song.（F）She can sings an English song.（F）She can sing an English song.（T）3．有些情态动词的过去时与其原形相同，有些与原形不同。

(1) 与原形相同的有：must --- must ought to --- ought to(2) 与原形不同的有：can --- could will --- would may --- might shall --- should三、含有情态动词的被动语态结构为：肯定式：主语+ can / may / must / should / + be＋动词过去分词否定式：主语+ can / may / must / should + not + be + 动词过去分词一般疑问句结构：Can / May / Must / Should + 主语+ be +动词过去分词?回答：Yes, 主语+ can / may / must / should.No, 主语+ can / may / must / should.+not.现在完成时时的被动语态：一、含有情态动词的被动语态结构为：肯定句：主语+has/ have been +done+ 其他.例：Her motorbike has been stolen. 她的摩托车被盗了。

否定句：主语+has/ have +not+ been+done+其他例：The task has not been finished yet. 任务尚未完成。

一般疑问句：【句型1】Has he (she, it,单数名词)+been+ +done+ 其他?【句型2】Have we ( you , they,复数名词）+ been + +done+ 其他?例：Has a new computer been bought? 买了一台新电脑吗?Have they been sent abroad to study English? 他们已经被派往国外学英语了吗?特殊疑问句：疑问词+have (has)+主语+been++done+ 其他?例：What has been bought by Tom? 汤姆已经买了什么东西?Who have been helped by the new computer? 谁已经得到这种新计算机的帮助?Where has the car been repaired? 这辆小汽车已经在哪里修理好了?注意：1. 在主动语态中，某些动词之后带有复合宾语，即宾语和宾语补足语，这个复合宾语由动词不定式来充当，to被省略，但在被动语态中，这个to还要还原。

例：I often hear her sing this popular song. （主动语态）She is often heard to sing this popular song .（被动语态）▲有这种用法的常用动词有：make , let , see , hear , watch , feel , notice等。

2.有些“be +过去分词”的结构并不是被动语态，它们可能是“系表结构（即系动词之后由过去分词来充当表语）。

”3. 只有及物动词和可有宾语的动词+介词词组才可以有被动语态。

Great changes have taken place in China.(正确)Great changes have been taken place in China.(错误)4. 不能用被动语态的情况不及物动词不能用于被动语态，如：appear，rise，die，happen，break out，take place等表状态动词不能用于被动语态，如：hold，have，cost，contain，become，look like等某些动词的进行时可表示被动，如：The meat is cooking. 肉正在煮着。

主动形式表示被动意义。

某些感官动词和系动词接形容词可以表示被动意义，如：look，smell等。

例：Her bedroom looks very clean and tidy. 动名词的主动形式表被动语态，如：need，worth等。

例：The book is worth reading.某些做表语的形容词后，用不定式主动形式表被动意义。
