I don't doubt that he has gone home 这句话对么不是doubt 作虚拟时,时态要后退一步 不是 had gone么?

问题描述:

I don't doubt that he has gone home 这句话对么
不是doubt 作虚拟时,时态要后退一步 不是 had gone么?

这句话是对的,doubt后不用虚拟

I don't doubt if he has gone home.
I think so.

像wish ,would rather 等后接虚拟语气,但是doubt这个词不做虚拟.

这里不是虚拟吧。我不怀疑他(现在)已经回家了。一般现在时。
