上学期 Unit 12 Mainly revision

　　学生在做这个练习答案的过程中，即复习了本课的词语，又掌握了与课文内容相关的新表达方式。这样他们完成其他练习也就不难了。教师可继续让他们将这个练习中的语句与课文作比较，找出异同，例如：

　　1) 课文—Many of the stars cannot be seen because they are too far away.
　　练习—Many of the stars are so far away that we cannot see them.
　　2) 课文—The moon travels round the earth. It is our satellite.
　　练习—The moon, our satellite, travels round the earth.

　　在这种比较过程中，学生又一次熟悉了课文内容及词语，特别是被动语态的用法。与此同时也锻炼了他们的思维能力，认识到英语语言表达灵活的特点，为下一步第48课的词汇教学做好辅垫。

关于数字表达方法的教学建议

　　在教授第47课时，为了给学生创造更多的机会，教师可提供火车列车时刻表中全国各主要城市间的距离表或世界各地航空路程表，将其放大制成挂图，贴在黑板上。可先根据　Practise的内容，让学生做快速的连锁问答，使他们熟悉句型和数字，并达到脱口而出的熟练程度。然后练习Ask and　answer可的材料。其中的重要句型是：

　　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, that's too big.
　　S3: How about 250?
　　T: That's 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（fanwen.oyaya.net）。

　　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 don't think any of them is interesting/enjoyable.
　　4) I think I shall …instead.
　　5) Why don't 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 can't 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: I've tried that. But I can't get it.

2)　A: What are you doing?
　　B: I'm trying to find our favourite TV programme—sports.
　　A: Have you got it yet?
　　B: No. I don't 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 don't think any of the programmes is interesting. I think I shall 　listen to the radio instead. Why don't you join me? It must be more enjoyable.
