关于虚拟语气的一个问题
You ——（not make）such a mistake if you had been more careful.
答案是（wouldn't have made）,
为何不能填hadn't done?
You ——（not make）such a mistake if you had been more careful.
答案是（wouldn't have made）,
为何不能填hadn't done?
表示与过去事实相反的情况,if you had been more careful.条件从句中用的是过去完成时态,主句中要用would have done
表示与过去事实相反的情况
从句：主语+had done
主句：主语+should/would/could/might+have done
eg：1.If I had got there earlier,I should/could have met her.如果我早到那儿,我就会见到她.（事实：去晚了）
2.If he had taken my advice,he would not have made such a mistake.如果他听我的劝告的话,就不会犯这样的错误了.
再问： 为何不能填hadn't done?
再答： 表示与过去事实相反的情况 从句：主语+had done 主句：主语+wouldn't have done
再问： soorry，原先一直把句型看反了……把条件句看成主句了
