问题描述：

can 和 could 的区别
If it were not for the fact that she_____sing,Iwould invite her to the party.
A.couldn't B.shouldn't C.can't D.might not
正确答案是C.我选的是A.请问为什么?搞不太懂.
什么时候只能用can,而不用could?

答

语法难点。有很多情况，建议你去翻情态动词的用法

答

could 语气 委婉一点 意思与can 一样

答

could是can的过去式

答

1.could是can的过去式，
2.could 语气 委婉一点 意思与can 一样

答

PS这是虚拟语态,用C有它的理由（事实上她不能是任何时候都不能事实型,而且也不需要后退时态等）这里是语法问题,不是一般的can和could区别.
I hope this may help you,but I am not sure.
