第03练 how often引导的特殊疑问句 一、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。 一、单项选择 1．— ________ do you like that book? —Quite interesting.
