　　试题答案及解析：

　　21.. Bnot…any more than…“与……同样不……”。本句意为：“摄入的维生素超过了身体所需要的量并不能使身体更好地发挥作用, 就像往油灯中倒入过多的油不能使其更亮一样。” no more…than 与not…any more than同义, 但句中前半部分已有not, 此处再填no是错误的。

　　22.. B此题测试的是平行结构问题, 即在并列或比较结构中，并列或比较的成分在语法形式上应一致。 如该句中应为：He spends as much time idling about as he spends (much) time studying.句中does 代替spends, idling与studying平行。

　　23. Cthe one 代替带定冠词的单数可数名词。句中代替the student，故选C。

　　24. D句子用的是just as…so…句型，后半部分要求倒装，所以应选D。

　　25.Cwhere引导定语从句，在从句中做地点状语，相当于from the top floor。

　　26. We agree to accept _________ they thought was the best tourist guide.

　　A. whatever

　　B. whomever

　　C. whichever

　　D. whoever

　　A. which are to be paid for

　　试题及答案解析：

　　26. Dwhoever引导名词性从句，并在从句中做主语，用来指人。they thought 是插入成分。

　　27. Cin that“是因为”，引导原因状语从句，符合句意。by which表示手段;so that引导目的状语从句;provided that引导条件状语从句。

　　28.Amade to do so是it is made to do so 的省略形式。unless是连词，应连接句子，所以除A以外的其他几个选项都是错误的。

　　29.B此处用过去完成时，是因为本句意指“到那次敲门，已经是第三次有人打搅我了”。句中用词was和that evening都说明指过去发生的事，到过去某一时刻为止已出现的情况用过去完成时。

　　30.Awhich在句中是关系代词，要引导一个句子，而B、C、D三个选项中都没有谓语，因此不是句子。本句意为：“政府同意提供服务设施，经费由居民在十年期间偿还。”
