--The mistake_____, I had been more careful.
---But you weren’t at that time.
A.might have avoided
B.would avoid
C.would be avoided
D.might have been avoided
答案
D
题目分析:句意:--如果我更加仔细一些,这个错误就会避免。--但是你当时没有。首先这个句子是个对过去情况的虚拟条件句,表示与过去事实相反的情况,if+主语+had done +其他+主语+should/would/could/might+have done+其他,所以排除BC,因为mistake和avoid是被动关系,所以选D。
