关于虚拟语气.
I have told my friend that if I_______ he was in hot water,i would go and help him out.
A:knew B:had known C:should know D:will know
您认为答案选什么?为什么?
书上的答案是选择A，说因为主句使用：would do something,故从句使用过去时间。
我最初也是选择B,但是转念一想，如果用had done,主句是不是就应该用would have done了？等待与大家继续探讨……

我认为应该选A,首先that引导的是一个宾语从句,而宾语从句中包含了一个条件状语从句,条件状语从句的时态,应根据他的主句,即I would go and help him out.是对于现在的虚拟,因此,状语从句中也是对于现在情况的虚拟,而状语从句中应保持时态的一致性,如果我现在知道他在危险中,我回去救他.我是不会在他遇难之前知道的（不会预知）,因此不用过去完成时.
