答案及解析：
1.【解釋】much more等于still more，意為“更不用說”，用于肯定句;much less也就是still less，意思相同，但用于否定句。故答案為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(dǎo)的從句中要求使用虛擬語氣，另外，對過去事實的虛擬應(yīng)用過去完成時，所以選A。
4.【解釋】在以lest和for fear that引導(dǎo)的狀語從句中，謂語動詞多用虛擬語氣，通常構(gòu)成是：should +動詞原形;本題用should+ have done的形式，表示動作發(fā)生在她“擔(dān)心”這個動作之前并已完成。故答案為B。
5.【解釋】but用作連詞時，不引導(dǎo)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后用一般過去時;如果是對現(xiàn)在事實的虛擬，but后用一般現(xiàn)在時。故答案為A。
