中小学教育资源及组卷应用平台 人教新目标七年级英语下册 Unit 3-Unit 4 语法知识过关检测 一、how long/how far/how often/how soon的用法 how long用来提问时间长短，意为“多长时间"，也可以用来提问物体长度意为“多长” eg：—How long does it take you to finish your homework 完成你的作业花费你多长时间？ —It takes me an hour to finish my homework. 完成作业花费我一个小时的时间。 —How long is this ruler？ —It is 20 cm long. 20cm长 —How long is the Yellow River？黄河有多长？ —It is 5464 km. 5464cm长 how far用来提问距离，意为“多远"。其答语分为两种 ◆ 用长度单位表示。 eg：—How far is it from your home to the bus stop 从你家到公共汽车站点有多远？ —It's five kilometers. 5千米。 ◆ 用时间表示。 —How far is the park from the supermarket 从超市到公园有多远？ —It's ten minutes' walk. 步行10分钟的路程。 注意：how long表示“路程有多长”和how far“距离上多远”，不容易区分，how far侧重从一地到另一地有多远；how long侧重整段路程多长；分不清楚的话，我们可以尽量少用how long表示路程。 how often询问动作发生的频率，意为“多久一次”。 eg：—How often do you visit your grandparents 你多久看望你的（外）祖父母一次？ —Once a week. 一周一次。 —How often does your mother take the medicine 你妈妈多久吃一次药？ —Three times a day 一天三次。 ◆ how many times意为"多少次"，用于询问次数。可用once,twice,three times等进行回答。 eg：—How many times have you been to Beijing 你去过北京多少次了？ —Twice. 两次 how soon意为“多久以后”，常用于将来时，用来提问“in+一段时间” eg：—How soon will they come back 他们多久以后回来？ —In two weeks. 两周之后。 —How soon will your mother finish cooking dinner 你母亲多久会做好晚饭？ —In an hour. 一小时后。 【考题练习】 —_____ have you been in China —For three years. —_____ will he back —In five minutes. —_____ do you visit you grandparents —Once a week. —_____ does it take you to finish your homework —an hour —_____ is the Yellow River？ —It is 5464 km. —_____ is the park from the supermarket —It's ten minutes' walk. —_____ is it from your home to the bus stop —It's five kilometers.
