虚拟语气与过去事实相反问题
到底是would have done 还是 had done
比如i wish that he had not made so much fuss about it
if the doctotor had been available ,the child would have been saved
the two strangers talked as if they ____friends for year
A should have been B had been
Cshould be
那为什么不选 A C呢 与过去事实相反啊 would have done
分不清什么时候用would have done 还是 had done
