选哪个?为什么?
答
选c，同位语从句，对fact的解释，
答
答案是C
由于题目上说I should invite her to the party是一般现在时，故选can‘t
该题亦可改为If it were not for the fact that she ___sing，I should have invited her to the party
should have dong表示本应该做某事却未做，此题选A
答
选 C.can not.if it were...,I would invite her...
这句是虚拟语气结构,但是她不会唱歌,这是事实,不能用虚拟语气.是真实的,而全句的虚拟语气表示和现在事实相反,所以用can not 表示现在时态.
答
选A，虚拟语气，表示能力要用could（can）
