单选题
4.
______ the truth, he wouldn't have lent her any money.
A、
Jack has known
B、
If Jack known
C、
Should Jack know
D、
If Jack knew
E、
Had Jack known
【正确答案】
E
【答案解析】
如果杰克了解实情,就不会借给她一分钱。
主句使用wouldn't have lent的结构,表明句子使用了虚拟语气,且是对过去的虚拟。而if虚拟句子在省略if的情况下要进行倒装。完整的从句为:If Jack had known the truth。倒装的方式是将had提前,故选E。
