The population of many Chinese cities has ________ doubled in the past twenty years.
A. larger than
B. more than
C. as great as
D. quite a bit
题目解答
答案
B. more than
解析
本题考查修饰动词“doubled”的副词短语的用法。关键点在于:
- “more than” 是唯一能正确修饰“doubled”的选项,表示“超过一倍”;
- “larger than” 和 “as great as” 通常用于比较名词,无法修饰动词;
- “quite a bit” 虽表示程度,但无法准确表达“超过一倍”的含义。
选项分析
A. larger than
- 错误原因:“larger than” 用于比较名词(如“China is larger than Japan”),不能直接修饰动词“doubled”。
B. more than
- 正确用法:“more than” 可修饰动词,表示“超过一倍”(如“Production has more than doubled”)。
- 句意匹配:题目中“人口翻倍以上”需用“more than doubled”表达。
C. as great as
- 错误原因:“as great as” 用于比较名词(如“as great as a hero”),且“great”不能修饰动词“doubled”。
D. quite a bit
- 错误原因:“quite a bit” 表示“很多”,但无法明确表达“超过一倍”的具体含义。
