时间状语从句中从句主句过去完成时，从句用什么时态

Question

如题所述

Answer 1

时间状语从句中，主句过去完成时，从句用什么时态？
一般用一般过去时。如
The bus had left when I got to the bus stop.
I had learnt a lot after I went to school.

Answer 2

英语语法中，叫做“第三类条件状语从句”或者“虚拟语态”
对过去表示虚拟
if
i
had
had
enough
money,
i
would
have
bought
that
house.
从句用过去完成时，主句用过去将来完成时，也就是“would
have
done”的形式。
