题目

25.______ the adviceof his friends,he would not have suffered such a heavy loss in his business.
A)if he took
B)if he shouldtake
C)were he to take
D)had he taken

答案

你好这里考查的是虚拟语气
根据后面的 would not have suffered 可以看出是与过去事实相反,
主句为：he would not have suffered such a heavy loss in his business.
他的生意就不会遭受如此打的损失
从句应该用过去完成时,所以选 D
