待会儿来给大家更帖。

考点聚焦
情态动词表示说话人对某一动作或状态的态度，可以表示可能、可以、需要、必须或应当等之意;情态动词没有人称和数的变化，但不能单独做谓语动词用，必须和不带to的动词不定式连用构成谓语动词;只有情态动词ought要和带to的动词不定式连用，在句中做谓语用;将情态动词置于主语之前即构成其疑问式，在情态动词之后加not即构成其否定式。
1.can和could的基本用法:(1)表示能力，如:He can speak English better than you.(2)在疑问句和否定句中表示怀疑、猜测或可能性，如:Can this green bike be Liu Dong`s?(3)表示许可时，You can/may go home now.(4)如果表示语气婉转，可用could代替can,如:Could you come again tomorrow?(5)can和be able to都可表示能力，两者在意思上没有区别。但是can只有现在式和过去式，而be able to则有更多的形式，如:He will be able to do the work better.

2.may和might的基本用法
(1)表示允许或征询对方许可，有“可以”之意，如:Ymu may use my dictionary.
在回答对方说“(不)可以做某事”时，一般不用may或may not,如:--May I use this dictionary?--Yes,please./Certainly.
在请求对方许可时，如果用“Might I …？”就比用“May I…？”语气更婉转些，如:Might I have a look at your new computer?
但在表示阻止或禁止对方做某事时，要用must not代替may not,如:--May we swim in this lake?--No,you mustn't.It`s too dangerous.

有时间再来……

自己先顶个~

只是想和大家分享一下，大家没事的时候就可以看一下。

不要沉。。

(3)在肯定句中must可以表示推测，表示“一定”或“必定”之意，如:--Whose new bike can it be?--It must be Liu Dong`s.I know his father has just bought him a new one.
