问题 He has been grinding out cheap romantic stories at the_______ of one a week.
选项 A、ratio
B、percentage
C、proportion
D、rate
答案D
解析 他一直以每周一篇的速度生拼硬凑廉价的浪漫小说。A．ratio“比，比率”，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，例如：The ratio of men’s jobs to women’s is 8 to 1．男性与女性工作岗位的比例是8比1。B．percentage“百分比”，例如：Unemployment has fallen by two percentage points this month．本月的失业率下降了两个百分点。C．proportion“比例”，通常用于下列搭配：in proportion to“依照比例”和in the proportion of“以……的比例”，例如：The pension was docked in proportion to earnings．养老金是按照收入比例扣除的。D．rate“比率”，通常用于at the rate of“按……的比率／速度”，例如：The train travels at the rate of 100 miles an hour．火车以每小时100英里的速度运行。注：grind out表示“创造出”，at the rate of one a week指“以一周一篇的速度”，此题选D。
