[d]checked?and?rechecked ? 1. 选[c]该题考察表示惊奇、高兴、遗憾、担心等感情色彩的形容词引起的主语从句中的虚拟语气的表达。在?anxious,sorry,concerned,happy,delighted等表示感情色彩的形容词后接的that?从句中，用should来修饰谓语动词。该句中有strange一次，意为“奇怪”，表示对事物的惊讶或不满，it为形式主语，that从句为主语从句， 要求从句中用虚拟语气的表达形式should+动词原形表示 2. 选[c]该题考察it’s+adj.+that主语从句的虚拟形式。观察句子结构可以看出这里为It’s+形容词(important)+that从句结构??形容词important做表语，主语从句需要虚拟形式should+动词原形，should可以省略 2.

Answer：1.must?have?made?a?joke?about?me 【解析】该题虚拟条件句的使用。本句是对过去事实的推测。观察句子可以看出这里为对过去的事实的肯定推测，应用must+have?done结构，句中someone?与make?之间为主动关闭。 2.better?than?it?would?otherwise?have?been 【解析】该句考察含蓄条件句的虚拟形式。otherwise相当于虚拟条件if?it?hadn’t?been?for?hisadvice,表示对过去的一种虚拟，所以要用would?otherwise?have?been. 4.
