问题: 状语从句 .

What would have happened_____,as far as the river bank?
A.Bob had walked farther
B.If Bob should walk farther
C.Had Bob walked farther
D.If Bob walked farther

解答:

我选C,首先这是一个省去了IF的条件状语从句,故而将HAD提前变为到装句,其次此处表示一种假设的虚拟语气,从首句的WOULD+HAVE+过去分词结构判断,不难确定后面的条件状语从句肯定用过去完成时.所以答案是C,Had Bob walked farther
