how often引导的特殊疑问句
1. how often 意为“多久(一次)”, 它引导的特殊疑问句用来询问某动作发生的频率。how often通
常是对一些表示频率的副词提问, 如：always, usually, often, sometimes, never等, 也可以对
表示“多久几次”之类的频率短语提问, 如once a week, twice a year, three times a day等。
—How often do you go back home? 你多久回家一次?
—Once a week/Often/Sometimes. 一周一次/经常/有时。
2. 特别提示：若仅对像once, twice, three times这样只表示次数的词语提问, 要用how many times
“多少次”, 不用how often。
—How many times have you been to Beijing? 你去过北京多少次?
—Only once. 仅仅一次。
3. 注意how often与其他短语的区别
（1）how long主要用来提问动作延续了多长时间, 答语通常含有“for + 一段时间”“since +
时间点”或since引导的时间状语从句。问句和答语中的谓语动词通常为延续性动词。how long也可以用来询问长度。
—How long can I keep this book? 这本书我能借多长时间?
—For two weeks. 两周。
—How long is the bridge? 这座桥有多长?
—About 1,000 meters. 大约1, 000米。
（2）how soon用来询问“过多久”动作才发生, 谓语动词常为终止性动词, 时态多为将来时, 答语通常为“in +一段时间”。
—How soon will you get here? 你还有多久能到这里?
—In five minutes. 五分钟以后。
（3）how far用来询问两地之间的距离“有多远”。
—How far is it from your home to your factory? 你家离你的工厂有多远?
—About twenty minutes’ walk. 步行大约20分钟。
（4）how many意为“多少”, 用来询问可数名词的数量。
How many hours do you watch TV every day? 你每天看几个小时的电视?
（5）意为“多少（钱）”, 用来询问不可数名词的数量或物品的价格。
How much are these books? 这些书多少钱?
