1 第二部 专题Ⅱ词汇 ㈦ 情态动词 考点揭密 典型例题解析 课时训练

2 考点揭密 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.掌握情态动词的特征：情态动词与其他动词是有区别的，它本身有一定的词义，表示说话人对某一动作的看法和态度，但不能单独作谓语，必须和另一个动词原形一起构成谓语；情态动词没有人称和数的变化，含有情态动词的句子改为问句和否定句时，无需添加助动词，可直接构成问句和否定句。

3 考点揭密 3.掌握常用情态动词can,could,may,might,must,need,
shall,will,should,would等的用法。 (1)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. (2)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。

4 考点揭密 (3)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。 (4)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。

5 考点揭密 (5)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。 (6)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。 
