1 ) How many kilometres by train is it from… to…?
2) How far away is…from…?
3) What about …?
教师要求学生用自己的词填入空缺的部分，这样可以造出许多句子，而且还可以复习或预习课文中出现的词语。例如：
1 ) How many li by air is it from … to…?
2) How far away is the earth from the moon?
3) What about other planet?
练习表示数量的方式有许多种，例如教师将一摞书带到课堂上，让学生猜每本书的页数。
做这样的对话：
T: How many pages do you think this book has?
SI: I think about 120.
T: No. The number is too small.
S2: What about 500?
T: Oh, thats too big.
S3: How about 250?
T: Thats quite right. 265.
在初中英语第一册和第二册中，我们已经陆续学习了数字的用法，教师可帮助学生回忆它们的念法，并做快速连锁问答。还可就长度、高度、重量等做问答，例如：How long is the Yellow River? How heavy is your bag? How tall/high is that tree?等等。
关于词语及对话练习的教学建议
本单元的生词大部分出现在阅读课文之中。而针对词汇的练习主要由48课的2和3两部分组成。即构词法的部分知识和有关选择电视节目的对话及词语练习。
首先，在教学构词法知识时，教师可采取提供部分例词，要求学生通过观察自己总结出构词规则的方式，让学生对构词法知识的认识从感性认识上升到理性认识，从而印象深刻， 记忆牢固。
现根据构词法将第一册到第三册中出现的有关单词归类如下：
复合名词：afternoon basketball bedroom birthday blackboard bookseller bookshop breakfast classmate classroom day-time doorbell Englishman fireplace football gate-keeper gateman grandparents granddaughter grandson handbag headache headmaster headteacher hometown homework housework kilometre know-all loudspeaker mooncake motorbike northeast northwest
pencil-box penfriend photograph playground policeman postcard railway reading-room shopkeeper southeast southwest spaceship sunrise sunshine teapot teamwork volleyball weekday
名词变形容词：interesting surprising northern southern woolen
动词变名词（结尾-er/or）：
cleaner driver inventor keeper teacher speaker traveller visitor worker
其次，提供讨论选择电视或电台节目的对话的教学过程。
建议教师先向学生展示电视和电台节目表，如下表：
TV: 1. Programme for Children Radio: 1. Music World
2. 9—part Series: Family (2) 2. News Report
3. China Reports 3. Foreign Languages Magazine
4. Series: Women 4. Window on Chinese History
5. Chinese Programmes for Foreigners
6. Music Bridge
7. Basketball Match (Beijing Vs Henan)
将主要句型提供给学，如下：
1) Which TV/radio programme shall we watch/listen to?
2) Which TV/radio programme do you think is more interesting/enjoyable?
3) Well, I dont think any of them is interesting/enjoyable.
4) I think I shall …instead.
5) Why dont you go and … instead?
6) Good idea. That is much better than … /…is better than…
学生看表进行对话练习。按全班、半班、两人小组操练句型，直至熟练为止。建议教师依靠表格和角色扮演等手段，让学生先口头熟悉对话内容，并采取各种形式进行口头操练，然后再据此完成不同的笔头练习。教师应鼓励学生积极思维，创造性地编出不同的对话。例如：
1) A: Which TV programme shall we watch? I cant decide.
B: Which do you think is more interesting?
A: Well, I think the children’s programme is more enjoyable.
B: Which channel is it on?
A: It is usually found on Channel 3. Try that.
B: Ive tried that. But I cant get it.
2) A: What are you doing?
B: Im trying to find our favourite TV programme—sports.
A: Have you got it yet?
B: No. I dont know which channel it is on.
A: It must be on Channel 14. Try that.
B: OK . But this is not sports.
A: Well, I dont think any of the programmes is interesting. I think I shall listen to the radio instead. Why dont you join me? It must be more enjoyable.
