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
3.选[a]该题考察非真实条件的虚拟。在表示过去情况的虚拟条件句中,条件从句用了过去完成时形式,主句可用should(would/could/might)+have+过去分词的形式
4.选[a]该题考察含蓄条件的虚拟。Butfor含义为“要不是”,用于此处可以表达假设条件,butforhistimelyarrival=Ifithadnotbeenforhistimelyarrival或Ifhehadnotarrivedontime.
