【复习目标】 1.
掌握情态动词的定义:表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词是情态动词。 2.
掌握情态动词的语法特征 4) 情态动词没有非谓语形式,即没有不定式,分词,等形式。 3.掌握常用情态动can, could, may, might, must,
need, shall, will, should, would等的用法。
【考点梳理】 can 可表示能力、允许、可能性、怀疑猜测,意为“能,会,可以”;can't意为“不会,不能,不可以”,还有“不可能”之意。could为can的过去式,用法与can类似,常用于过去时中;could还可用于现在时中表示委婉客气,相当于can;could也可表示惊讶怀疑,不相信,如:He couldn't be a thief. may表示允许、也许,意为“可以,也许,可能”。对may的一般问句的回答,肯定回答一般是:Yes, please./ Certainly./
Sure等,否定回答一般是:Please don't./No,you can't/mustn't. might是may的过去式,与may用法类似,常用于过去时中;用在疑问句中,还可表示委婉客气。 must 表示必须要做的事,意为“必须,应该”。must一般问句的否定回答用needn't或don't have to,而不用mustn't, mustn't意为“不可以,不能”,表禁止,不许可。另外, must还可表示有把握的推测,意为“一定、肯定”。must的过去式还是must。 need 作情态动词主要用于问句和否定句中,意为“必要”。need一般问句的肯定回答用 must,否定回答用needn't,如:Need I do it right now?肯定回答:Yes, you must。否定回答:No, you needn't. need作行为动词,有人称、数和时态的变化,后接动词要加to do不定式。 shall, will用来征求对方意见,shall用于第一人称,will用于第二人称,用来表示意愿;shall用于第二、第三人称,will用于第一人称。 would, should为will,shall 的过去式,would用于现在时,表示委婉提出请求、建议或看法,如Would you please not do it
again? should还有“应该”的意思,但语气比must 弱。
