单选题 --Do you know ______ the price of meals on the railway has increased recently?
--Yes, by 15%.
  • [A] how long
  • [B] how often
  • [C] how much
  • [D] how soon


【正确答案】 C
【答案解析】[精解] 本题考查疑问副词。本题前一句问“你知道近来火车饭菜价格涨了多少钱吗?”对金钱的多少提问一般用how much。how long是问时间的长短；how often是对事物发生的频率提问；how soon表示时间，意思是“多快”。根据分析本题的正确答案选C。
[拓展] 感叹句通常由what/how引导，what一般修饰名词，how一般修饰动词、副词、形容词，句末用感叹号。几种常见结构： 1)How+ adj./adv. +主语+谓语! 2)How(=adv.)+主语+谓语! 3)What +adj.+复数名词/不可数名词+主语+谓语! 4)What+ a/an +adj.+单数可数名词+主语+谓语! 5)How+ adj. +a/an+单数可数名词+主语+谓语注意：在一定条件下，what引导的感叹句与how引导的感叹句可相互转换。例： What delicious moon-cakes they are! =How delicious the moon cakes are! What a beautiful flower it is! =How beautiful a flower it is!
