语法精讲
1.can/could的用法
【先感悟】

②Someone is knocking at the door.Who could it be
有人在敲门,可能是谁呢
③Anybody can make mistakes.

④Can I go now
现在我可以走了吗
⑤—Could I come to see you tomorrow

他不可能去了上海,因为我刚才还看到他了。(过去)
⑨I could have come on time,but my car broke down on the way.
我本来可以按时到达,但是我的车在路上抛锚了。
【善归纳】
can/could意为“可能”,表示　　　　　　,一般用于否定句和疑问句;can可以表示理论上的可能性,指常有的行为或情形,意为“有时会……”;can/could表示请求或允许,表示请求时,口语中常用could代替　　　　　　,使语气更委婉,回答时用can;can’t/couldn’t可以推测现在的情况、正在发生的动作或过去已经发生的动作。could have done表示“本来有可能做某事而事实上未做到”。
can’t/couldn’t+do/be 不可能……(对现在情况的推测)
can’t/couldn’t+be doing 不可能正在做……(对此刻动作的推测)
can’t/couldn’t+have done 不可能做了……(对过去动作的推测)

②The story may not be true.
这个故事可能不是真的。
③Today is Sunday.She may not be in the office.

⑦The pills might have helped him,if only he’d taken them regularly.
他当时要是按时服药,也许可以对他有帮助的。
【善归纳】
may和might表示允许或请求,might比may的语气更　　　　　　;表示可能性时,might比may的可能性　　　　,may表示的可能性比can小(主要用于肯定句或否定句,疑问句用can代替);may/might可以推测现在的情况、正在发生的动作、过去已经发生的动作以及将来的情况。
may/might+do/be 可能……(对现在或将来情况的推测)
may/might+be doing 可能正在做……(对此刻动作的推测)
may/might+have done 可能做过……(对过去动作的推测)
may/might as well表示“最好还是……,不妨……”;may/might well表示“很可能”。另外,may还可以用于　　　　　　,表示祝愿。

【善归纳】
must表示“必须,应该,一定要”,强调　　　　　　,只有现在时形式,否定式是must not(mustn’t),must开头的问句,其否定回答要用　　　　　　或
　　　　　　来表达。must表示推测时,可以推测现在的情况、正在发生的动作或过去已经发生的动作。
must+do/be 一定……(对现在动作的推测)
must+be doing 一定正在做……(对此刻动作的推测)
must+have done 一定做过……(对过去动作的推测)
