1.【解释】much more等于still more，意为“更不用说”，用于肯定句;much less也就是still less，意思相同，但用于否定句。故答案为D。

2.【解释】考查名词性从句。第二句话中what little he knows about it作整句话的主语，其中what用做little的定语，意思是“所……的一点点”。

3.【解释】would(had) rather, would as soon, would sooner或would prefer所引导的`从句中要求使用虚拟语气，另外，对过去事实的虚拟应用过去完成时，所以选A。

4.【解释】在以lest和for fear that引导的状语从句中，谓语动词多用虚拟语气，通常构成是：should +动词原形;本题用should+ have done的形式，表示动作发生在她“担心”这个动作之前并已完成。故答案为B。

5.【解释】but用作连词时，不引导虚拟语气的句子，但可以同前半句是虚拟语气的句子连用。如果前半句是对过去事实的虚拟，but后用一般过去时;如果是对现在事实的虚拟，but后用一般现在时。故答案为A。
