If I had V-ed, I would …
结构︰If…had+过去分词…，主词+would/should 等+原形动词+now/today
说明︰这是<时态>不一致时的假设<句型>，亦称混合假设条件句。即：if <子句>若与过去事实相反，用<过去完成式>表示；而<主要子句>若与现在事实相反，则用过去式<助动词>表示。此类<主要子句>句尾通常有表现在的<时间副词>，如 now，today 等。

I wish … + V-ed …
结构︰I wish+（that）+主词+动词过去式/过去完成式（had+过去分词）…
说明︰I wish 之後以 that <子句>为<受词>时，该<子句>的<动词>一定要用<假设语气>：若<动词>用过去式，表示与现在事实相反的愿望；若用<过去完成式>，则表示与过去事实相反的愿望。“I wish+that-<子句>”的<句型>也可用“I would rather+that-<子句>”取代。而 I hope 之後以 that <子句>做<受词>时，该<子句>用一般<时态>。
