if i --(know) how to sing the song,I would have joined you that day
答案是had known这句话是考虚拟语气的把?我还没有学过,谁能讲解一下虚拟语气的用法?还有一道题目：if I had the opportunity,--- to tell them why.A\I likeB\I'd likeC\I had likedD\I'd like

我就简而言之说一下这个题,第一题是对过去的虚拟,对过去的虚拟结构是从句：主语+had+done,主句：主语+would/could/might+have+done.第二题选B或者D（怎么两个选项是一样的）第二题是对现在的虚拟,结构是从句：主语+had/were,主句：主语+would/could/might+动词原形这些都是固定结构,记住就行补充一下对将来的虚拟：从句：主语+should do/(were to)+do,主句：主语+would do
