参考答案：
1.C 考查虚拟语气，此题为由otherwise引导的与过去事实相反的虚拟语气，它的主句结构为：主语 would/could/might have done,所以选C。
2.D without引导的条件状语重句，主句要用虚拟语气，这是对过去的假设，意为如果没有。。。。会怎么样。因without表一种条件，“如果没有”，所以without your help为从句，we______so much为主句。与现在事实相反的话，主句用would/ might... 动词原形。
3.C 因为suggest that sb (should) do sth 固定搭配，句子中的 suggested 也是建议的意思，而这个固定搭配中的should可以省略，所以必须选择一个一般时态动词原型的，故选C。
4.A 这是一个现在虚拟语气.选A,it 是形式主语,that引导的从句是真实的主语.从句动词省略了should,不省略的话,应该是it is important that I should speak with Mr.Williams immediately.这种类型的句型是It is 形容词 that 引导的主语从句,当这个做表语的形容词有重要、必须的意思时,从句用现在虚拟,即should 动词原形,而通常should 可以省略,直接用动词原形。故选A。
5.：C 考查情态动词用法。不同中的其它动词should是一种特殊用法,意为“竟然“表示一种惊讶的语气;句意：真是让人奇怪，他竟然在如此重要的一次考试中没有及格。根据句意说明这是在过去发生的事情，使用情态动词 have done"的形式;故选C。
6.A 在由“for fear that…”引导的从句中,用“should 动词原形”。
7.D It's (high) time that sb did sth that可以省略 这是一个固定句型，did可以换成任意动词的过去式。意为“到了某人要做某事的时候了”。
8.B 此题考查的是虚拟语气的使用.It;s about time是虚拟时态的标志.时态与语境事态错一个,根据语境,是该回家的时候了,是现在时态,错一个就是一般过去时,故B项。
