基本上是can的过去式
但是还是有其他的用法
要看用在哪里作者: louisma 时间: 2013-10-28 05:13 PM
虚拟语气喔作者: [D]-KY 时间: 2013-10-31 06:40 AM
could = suggestion/past
can = assertion

I could do it (我也许可以做到)

'Could' is used to make polite requests. We can also use 'can' for these but 'could' is more polite.
Could you help me, please?
Could you lend me some money?
Could I have a lift?
Could I bother you for a moment?作者: ian20 时间: 2014-2-22 12:13 PM
could也有虚拟或委婉语气的意思作者: peter_gijb 时间: 2014-4-30 11:11 AM

I think "could" sounds more polite as compared to "can".
Like when you ask a question in "Can", you are expecting the person to reply a "yes", or you may be angry.
