【Grammar】--情态动词could的用法
情态动词could用于有礼貌地提出要求或请求准许，用于疑问句，代替can，在时间上与can没有区别，但语气要比can委婉、有礼貌。

否定回答还可以用I'
mafraidnot.等
⏹Couldyoupleaselendmeyourdictionary?
⏹Yes,sure.

（1）could为can的过去式，表示能力。
Hesaidthathecouldn’tcome.
（2）表示惊异、怀疑、不相信等态度，主要用于否定句和疑问句，此时could与can无时间上区别，但语气比can缓和，情绪要弱。

（3）表示可能性，指对将来、现在或过去某种可能的推测。
Mywifeisinhospital—ourbabycouldarriveatanytime.
（4）用于虚拟语气
