二、教材分析

1、教学内容

(1) Before reading

21st century Mobile Phones

What of the future? It has been predicted that mobile phones might soon replace our wallets. For example, instead of handing over cash to pay for groceries, our mobile phones would be scanned and the cost added to our next phone bill. The idea that in the future we won’t need to carry money seems crazy, but 80 years ago, the idea that you could walk out of your house with your phone in your hand probably seemed crazier! Mobile phones have become a major part of our lives and one wonders what the next technological advance will be.

(2) Reading

Hannah Jones looks into the future of futurology.

I love talking about the future --- and I am not the only one. Over the centuries, people have always wondered about the future. Some like to read fantasy stories and imagine what the world will be like in 10, 50 or even 1’000 years’ time. Others foresee future opportunities and problems. They plan the future of the world for a living. These people are called futurologists.

This weekend, hundreds of futurologists are meeting at Newcastle University. The seminar starts on Friday and the experts will be discussing the influence of technology on the future. The future is now big business. I clicked into the websites of some futurologists and here’s what they’re predicting:

·The technology already exists, so very soon all of us are going to use our voices to give instructions to computers. ·In the next few years, we will be communicating with our friends around the world using life-sized video screens in our living rooms.

·By the year 2020, computers will already have become more handy and also more powerful than the human brain both in terms of intelligence and the amount of information they can store.

·By the year 2030, development in biochemistry and medical science will make it theoretically possible for us to live for at least 150 years. Tiny, insect-like robots may be sent around our bodies to carry out repairs and keep us healthy.

·By the middle of the century, computers that are millions of times smarter than us will have been developed. We will be linking our brains to these computers and a huge database. A new species might have developed!

·By the end of the century, we will have discovered other places in our solar system suitable for living and will have discovered ways to go further into space.

I’ll be there in Newcastle this weekend. At nine o’clock on Saturday morning, I’ll be sitting in the front row and listening to the great Duke Willard talking about the future of my brain. If you can’t beat the future, join it!

(3) Post-reading

a) The Programme of the futurologists’ conference

Tell the statements T or F according to the information in the table. If false, correct it.

b) Title: _____________________________

ISRAEL: In our world's oceans, wind, waves and underwater currents spread dissolved air through the water. At a depth of 200m below the sea, there is still about 1.5% dissolved air. Fish gills work comfortably with this amount of air, and now Israeli inventor Alon Bodner has designed a way for man to do the same, eliminating the need for cumbersome oxygen tanks and expensive air compression units. If it goes to plan, a tankless underwater breathing system in the form of a vest that will be attached to a diver should be available in a few years time.

2、教材处理

由于本课阅读材料篇幅较短，理解难度不太大，因而在课前安排学生重读“21st century Mobile

Phones”（简写）内容，要求学生在1G、2G、3G手机的基础上，设计自己喜爱的未来4G产品。然后附加了一段有关未来学及未来学家的背景材料，让学生对相关知识先有所了解，为更好进入话题做好铺垫。另外， 根据学生的实际及认知规律，将练习10改编成“阅读表格信息，判断正误”，还增加一段选自China Daily的新闻阅读，作为拓展练习。而其余练习如Grammar部分以及词汇巩固，设计成学生自主学习的课后练习。总之，教材处理遵循两个方向：①每个环节环环相扣，突出教学目标；②学生能自主完成的任务，教师绝不替代。

3、教学目标

To read a text about predictions, summarize the main ideas of paragraphs, and then select an appropriate headline for the whole text.

To practise using the words and expressions.

To practise using the Future Perfect and Future Continuous tense.

4、教学重点和疑点

(1)To help students summarize the main idea of each paragraph and decide an appropriate headline for the text.

(2)To practise using the Future Tenses to give future predictions.

三、教学设计

1、总体思路

本课的教学设计以学生先学为主，辅之以教师的精讲精评。因而教学整体过程以学案形式呈现。学生独立通过课前或课中自学，初步了解相关内容，发现问题，与同伴讨论、交流，教师引领其研究、分析、解决问题。因而学案中必须明确学习目标、具体阅读方法、学习重点和疑点、课前预习先学、课堂交流研讨、课内训练巩固、课后拓展延伸等内容。

2、教学过程

Step1 Before reading

1. Watch an advertisement on mobile phones.

[设计说明]观看手机广告，以图片直观形式集中学生注意力，使学生自然进入学习状态。

2. Talk about what 4G mobile phones will be like.

[设计说明]通过小组（4-6人）讨论，让学生描述未来手机的外观及性能，为下面的阅读理解及语言运用打下埋伏。

3. Discuss what Futurology is concerned about.

[设计说明]学生对“未来学”比较陌生。通过多媒体输入相关背景信息，有利调动学生的情绪，排除陌生感，唤起其亲近科学技术的冲动，还可帮助学生更好地理解本课阅读文章。

Step2 Reading

1. Read the text quickly. Summarize the main idea of each paragraph.

[设计说明]通过快速阅读，学生可快速获取文章每一段的主要信息，即训练学生有目的进行阅读，又为归纳全文主旨大意做好准备。

2. Decide which of the following headlines will be the best title of the text and give reasons.

From the Past to the Future The Future Business

Tomorrow’s World A perfect Future?

_____________________________________________________________________________________________________________________________________________________________.

[设计说明]这一步骤可促进学生对已获得的信息进行分析和筛选，提高学生语言表示及概括能力。

3. Find out how many predictions the writer has found on the Internet. And complete the table.

[设计说明]确定了文章主旨大意之后，将注意力聚焦具体信息，可自然转入新的语言点（将来完成时和将来进行时）的学习。

4. Voice your opinions: Why is the writer interested in futurology?

Which of the predictions would you like to come true?

[设计说明]学生有了足够的语言输入后，可尝试组织语言并输出信息。这样，即能引领学生领会作者的写作意图，又给空间学生围绕主题展开对未来的憧憬。

5. Read the text again and speak out at least one sentence you think excellent.

[设计说明]提供机会学生说自己喜爱的句子，即突出了学生课堂的主体地位，又可培养学生更高的学习热情。与同伴交流，还可检查发音及语速，促进合作提高。

Step3 Post-reading

1. Tell the statements T or F according to the information in the table.

[设计说明]改编练习10的形式，可将锻炼学生阅读信息、理解信息的能力与运用新语言知识的能力结合起来。另外，考虑到不少学生以前做类似练习都觉得较难，这样处理也可降低难度。

2. Read the news from China daily. First underline the topic sentence and then decide a title for it.

[设计说明]从课内到课外，将学校学习与社会新闻结合，引导学生关注社会，关注科学技术对人类生存的巨大影响，是课堂教学不可忽视的一方面。同时，也进一步突出了本节课把握文章主旨大意、培养阅读能力的目标。

Step4 Homework

1. Match the vocabulary with the explanations.

2. Complete the sentences with the correct form of the words given.

[设计说明]学生认为阅读的最大障碍是词汇不过关。这两个练习可帮助学生归纳、理解和运用本课词汇。

3. Read more information about “the Future” and do exercises.

[设计说明]课堂中，学生对将来完成时和将来进行时已自然地运用上了，但还存在疑虑。学生通过对具体材料的感悟，可自己归纳、整理和完成任务。教师只需个别点评。
