单选题 All the public facilities require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than ______ through taxes alone.
A. raised B. is raised
C. to raise D. raising

【正确答案】 B

【答案解析】requiring more money than is raised through taxes alone“需要比仅仅通过税收筹集的资金还要多的钱。”比较连词than一般应接句子，这就意味着than后面的结构要有谓语，从这一点分析，只有B正确。另外，比较从句中的主语money省略了，可以理解为...than the money which is raised through taxes alone。than的这种用法比较特殊。
