答案及解析：1.【解釋】much more等於still more，意爲“更不用說”，用於肯定句;much less也就是still less，意思相同，但用於否定句。故答案爲D。
2.【解釋】考查名詞性從句。第二句話中what little he knows about it作整句話的主語，其中what用做little的定語，意思是“所……的一點點”。
3.【解釋】would(had) rather, would as soon, would sooner或would prefer所引導的`從句中要求使用虛擬語氣，另外，對過去事實的虛擬應用過去完成時，所以選A。
4.【解釋】在以lest和for fear that引導的狀語從句中，謂語動詞多用虛擬語氣，通常構成是：should +動詞原形;本題用should+ have done的形式，表示動作發生在她“擔心”這個動作之前並已完成。故答案爲B。
5.【解釋】but用作連詞時，不引導虛擬語氣的句子，但可以同前半句是虛擬語氣的句子連用。如果前半句是對過去事實的虛擬，but後用一般過去時;如果是對現在事實的虛擬，but後用一般現在時。故答案爲A。
