单元：Unit1 Living with technology
板块：Reading 1
Thoughts on design:
这是Reading 板块第一课时。

第一课时侧重阅读理解，主要关注提升学生的阅读理解能力和思维能力。

涉及到的阅读技能有：把握文体风格，理解中心思想，按照时间线索查找细节信息，了解行文结构和信息组织方式, 通过阅读标题了解特定信息，对长句和难句的理解等等。

涉及到的思维能力是：进行信息重组再加工，学习运用所学知识和技能进行创造等。

Teaching aims:
1.students will be able to read an article from a book about the evolution of video
and sound devices;
2.students will be able to know the reading strategy—understanding headings;
Teaching procedures:
Step 1 Lead-in
Where is this piece of writing taken from?
What is it about?
(Explan ation)
在阅读导入环节，提出两个问题，提示学生关注本文的文体特点，目标读者和中心内容，对提高他们的阅读理解能力和思维能力都会有所帮助。

从应试的角度来看，这些也是常见题型，平时可以因地制宜地进行这种训练。

(Explanation)
本文为科技类的说明文，信息量很大，时间跨度很长，但其中内容多为客观事实，从语言学习的角度，学生只需了解即可。

所以阅读的重点应在于如何获取信息和如何进行信息分类等，需要深层次理解的内容其实并不多。

但鉴于今后学生在学习和工作中会遇到大量此类文章，对此进行阅读方法的指导还是非常有必要的。

建议阅读前请学生思考：面对信息量巨大且看似枯燥的这篇文章，如何迅速高效地抓住关键信息？指导学生通过快速浏览课文，找出关键字词，如：development、evolution、in 1925、later in 1928等一系列时间指示语，从而抓住文章的脉络，即时间线索，再依次找到有关其发展历史的关键信息。

Step 4 Reading strategies 2
How is so much information organized?
Take a close look at the structure of the passage and you’ll find out: Subtitles are helpful!
(Explanation)
在此之前的教学环节中，学生沿着时间线索了解了本文的重要信息，此时可以在学生亲身实践的基础上，适时指导学生关注文章的行文结构和信息组织方式，这对于他们阅读能力和写作能力的提高都会有好处。

同时，也非常自然地过渡到本单元的Reading strategy: Understanding headings。

Step 5 Reading for details
P4 C1
1F 2T 3F 4F 5T 6T
(Explanation)
到这一步骤之前，学生已经通过阅读理解了文章中最关键的信息、行文结构和信息组织方式。

现在可以通过提问，引导学生关注和文章主题相关的细节信息，进一步培养他们在阅读中抓住细节的能力；另一方面，这篇文章不仅为学生提供相关信息，同时又富含字、词、句等语言材料可供学生学习。

学生在回答问题的同时，也会不由自主地关注并使用一些词汇和句型，这样就为下面语言点环节的学习提前进行了铺垫。

Step 6 Understanding difficult sentences
1.Regular public broadcasting followed shortly af ter, first beginning on 11 May
1928 in New York.
Regular public broadcasting followed shortly after.
Regular public broadcasting first ____ on 11 May 1928 in New York.
2. Satellites were used to broadcast TV beginni ng in 1962.

3. … broa dcast the signals they get from satellite receivers to the population living nearby.
…broadcast the signals they get from satellite receivers to the population ____ ____ nearby.
4. … adopt many of the principl es first discovered by Fransworth.
adopt many of the principles ____ ____ ____ ____by Fransworth.
5. …and so satellite dishes can often be seen distributed throughout the
countryside and the remote areas.
… and so you can often see ____ ____ ____ throughout the countryside and the remote areas.
6. …it was not until 1938 that the first colour TV programme was broadcast.
The first colour TV programme _______________________________.
7. Technology is now c hanging faster than most people can keep pace with.
Most people _____________________.
[Explanation]
从帮助学生进行长句和难句理解的角度，从课文中选出几个句子。

具体的语法项目和功能此时不必详细教授，着眼点应在于帮助学生理解句意，即以扫清阅读理解的障碍作为出发点。

如上面的例子中都涉及到分词结构，此时不必详讲，如果详讲，几节课恐怕也讲不完，可以通过“句型转换”的形式帮助学生理解句意，形成主被动意识，为今后进一步学习积累语感，打下基础。

Step 7 Writing a summary
Can you briefly introduce the evolution of video and sound devices?
Step 7 Homework
(Explanation)
可先讨论出要点，讨论时可不必具体到哪一年，说出大致事件即可。

也可以鼓励他们说出一些代表性人物和他们的贡献等。

可以鼓励他们思考“如何才能写出一个与众不同的有趣的介绍”，然后回家后再查阅相关资料，写成书面作业，留到下节课再讨论。

总之，此环节的目的是运用所学知识和技能进行创造，有助于提高他们的思维能力。

至此，Reading板块的第一课时结束。
