would have done 的用法疑惑中

nesstang

高中的时候学的：would have done 是虚拟语气，表示“本能干什么，但是没有干..."

eg. I don't blame you. I would have done the same.

但是在做GWD的时候做到过这么一道题

For many people, household labor remains demanding even if able to afford household appliances their grandparents would find a miracle.

A.even if able to afford household appliances their grandparents would find a miracle
B.despite being able to afford household appliances their grandparents would find a miracle
C.even if they can afford household appliances their grandparents would have found miraculous
D.although they could afford household appliances their grandparents would find miraculous
E.even if they are able to afford household appliances which would have been a miracle to their grandparents

答案选择的是C，解释是说，would have done 表示是对过去的猜测，所以C的would have done 会比D项中的would好，我就晕乎了，是不是在gmat中would have done 不表示“本能干什么，但是没有干...”
