______ her rudder,there is no doubt she would have won ...

问题描述:

______ her rudder,there is no doubt she would have won ...
two choices:
1/ not having lost
2/ had she not lost
which one is correct,why.

选2 "毫无疑问她本该赢的,如果她没有丢失她的方向."
这里是虚拟语气,对过去事实的虚拟.语法是:主句would/should/might have done,从句had done.即:"If she hadn't lost her rudder"=Had she not lost,为表强调,这里把"had"提前了.所以选2..
