题目

问一道虚拟语气的题目
Henry______ a rich man today if he had been more careful about his investment in the past.
为什么是填would be?是因为本来主句一般将来时,从句现在完成时,所以时态退一步就是would be 了?

答案

解析如下：
虚拟语气中,表与过去事实相反的虚拟语气
主句时态用would have done
从句时态用had done过去完成时.
本句中从句时态应该是：would have been
但此句从句时态之所以用would be 是因为此句是一个混时条件虚拟句.
因为从句已经有明确的时间状语today,表达的是对现在的虚拟,所以时态用
would be 而不是would have been .
