问题 According to the new tax law, any money earned over that level is taxed at the______of 59 percent.
选项 A、ratio
B、percentage
C、proportion
D、rate
答案D
解析 名词辨析题。这四个词都有“比，比率”的含义。ratio常用作数学术语，多以具体数据体现两个关系平行的事物的数量之比，所涉及的两个比较项必须同时出现，句中只有59％，排除[A]。percentage多指部分在整体中所占的准确的百分率、百分比，既然句中已经出现了59％，显然这里不会再用percentage一词。proportion可指两个关系平行的事物在大小、数量、程度等方面的比例、比率、比重等，突出孰大孰小，也可指部分在整体中所占的比例，还常表示整体中各部分之间协调或和谐的关系，指匀称、平衡，常与介词in搭配，in the proportion of意为“按……比例”，句中介词为at，故排除[C]。rate多指动态的率、比率、速率等，单指“……率”时用rate，常用于构成复合短语(birth rate，death rate)；多与介词at搭配，at the rate of…，故[D]为答案。
