情态动词表示说话人的语气、情绪和态度。情态动词没有实义动词的各种变化,有的情态动词(如________、________、__________、have to等)有过去式,如句(1)(2)(4),有的情态动词没有人称和时态的变化,如句(6)。在意义上,大多数情态动词有多个意义,如can可以表示______[如句(3)]、可能、许可等;shall可以用于第一、三人称作主语的疑问句中,表示说话者________________[如句(5)],用于第二、三人称作主语的陈述句中,表示说话者的命令、警告、威胁、允诺、决心等。在用法上,情态动词与助动词一样,其后须接动词原形,构成_______。
can
may
will
能力
征求对方的意见
谓语
1.表示能力,意为“能、会”;could是can的过去式,表示过去的能力。
2.can可用于肯定句中,表示客观或理论上的可能性,意为“有时会”。
3.表示请求或许可。在疑问句中,could可以代替can,语气更加委婉,肯定回答时要用can,不用could。
一、can和could的用法
4.表示说话者的主观推测,意为“可能”,用于否定句和疑问句中。can比could语气强。
5.用于固定习语中:can't...too/enough意为“无论……也不过分、越……越好”;can't but do sth.意为“不得不做某事、只好做某事”;can't help doing sth.意为“禁不住做某事”。
1.表示请求或许可。在疑问句中,might可以代替may,语气更加委婉。给予许可时用may,不用might。
2.表示推测,意为“或许、可能”,通常用于肯定句和否定句中。might比may语气弱。
二、may和might的用法
3.表示祝愿,常用结构为:May+主语+动词原形!
4.用于固定短语中:may/might as well+动词原形,意为“不妨、还是……为好”;may/might well+动词原形,意为“很可能……”。
1.意为“必须、一定要”。must强调说话人的主观看法,have to则强调客观需要;must没有人称和时态的变化,而have to 有人称和时态的变化。在回答带有must的问句时,否定式常用need not (needn't)或don't have to。
2.must用来表示推测,意为“一定是”,只能用在肯定句中。
三、must和have to的用法
3.must意为“偏要、非要……不可”,常用于疑问句和条件句中,偶尔也用于陈述句中。
4.mustn't表示禁止,意为“不可以、不允许”;not have to意为“不必”。
1.用于第一、三人称作主语的疑问句中,表示说话者征求对方的意见。
2.用于第二、三人称作主语的陈述句中,表示说话者的命令、警告、威胁、允诺、决心等。
3.用于条约、规定、法令、法律等文件中,表示义务规定,意为“必须”。
四、shall的用法
1.should和ought to均表示责任、义务、劝告、建议等,意为“应该”。
2.should和ought to均表示推测,指合乎理想的情况或结果,意为“按说应该”。
3.should表示出乎意料、惊讶的口气,意为“竟然、居然”。
五、should和ought to的用法
六、need和dare的用法
1.need既可作情态动词,也可作实义动词。作情态动词时,意为“需要”,常用于否定句、疑问句和条件句中。needn't意为“不必”;对need引出的一般疑问句,作肯定回答时用must而不用need,作否定回答时用needn't。
2.dare既可作情态动词,也可作实义动词。作情态动词时,意为“敢、敢于”,后跟动词原形,常用于疑问句、否定句和条件句中。
七、will和would的用法
1.与各种人称连用,用于陈述句中,表示主语的意志、意愿或决心。will指现在,would指过去。
2.表示征求意见或提出请求,多用于第二人称作主语的疑问句中。would比will语气委婉。
3.表示习惯性动作、固有属性或必然趋势,意为“总是、习惯于”。will指现在,would指过去。
八、“情态动词+have done”的用法
情态动词+have done 含义
must have done 过去一定做过某事(肯定句)
can/could have done 本来能够做但却未做(肯定句)
可能做过……吗?(疑问句)
不可能做过……(否定句)
