【每日一练】八年级英语人教版上册Week02：how_often引导的特殊疑问句
中考频度：★★★☆☆难易程度：★★★☆☆（2018﹒江苏宿迁）—_____do you visit your grandparents, Timmy?—Once a week.A. How manyB. How longC. How muchD. How often【答案】D【解析】句意：—蒂米, 你多久去看望你的祖父母一次? —一周一次。
考查特殊疑问词辨析题。
根据答语Once a week, 可知问的是频率, 需用how often提问, 故选D。
【归纳拓展】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。
