Ⅲ. 教材分析与教材重组
1. 教材分析
本单元以“Life i ( http: / / www.21cnjy.com )n the future”为中心话题，旨在通过本单元的学习，让学生大胆发挥想象，对人类今后的生活环境，生活方式进行猜测，并在此基础上，对人类的种种活动进行反思，提倡环保生活意识。同时让学生学会过去分词作定语和作状语的不同用法。最后让学生将本单元所讨论的话题和推测手法相结合，学习怎样写report。
1.1 Warming Up 部分利 ( http: / / www.21cnjy.com )用一个关于“住”和“行”的对比研究表格引导学生回顾过去，认识现在和展望未来。通过这一活动，引发学生对过去，现在和未来的思考，使学生对将要阅读的文章有个知识准备。
1.2 Pre-reading 部分 ( http: / / www.21cnjy.com )让学生充分运用发散思维，先列举当今世界人类面临的一些突出问题，然后要求学生思考为什么会产生这些问题，这些问题中哪些在未来社会仍然可能存在，哪些将会被克服，哪些将会恶化。为下面的阅读做了铺垫。
1.3 Reading 部分通过 ( http: / / www.21cnjy.com )一封发自未来的电子邮件，讲述了作者Li Qiang怎样安全到达“未来世界”，他对“未来世界”的印象，以及“未来世界”的日常生活方式和交通工具情况。阅读时要把重点放在“未来世界”生活与当今生活的不同点上。
1.4 Comprehending 部 ( http: / / www.21cnjy.com )分设计了三个教学活动来加深学生对Reading部分的理解。第一个活动要求学生通过阅读找出“未来世界”在以下几个方面的变化：跨时空旅行，交通，住房，城镇环境和空气质量。接着让学生在此基础上得出自己的结论，哪些变化好，哪些变化不好，并说明理由。第二个活动要求学生通过阅读来判断Li Qiang对“未来世界”的态度是乐观的还是悲观的。学生要在文中找出支持自己观点的论据，尽可能说服别人。第三个活动让学生想象一下Li Qiang将会去参加哪些活动。这样既鼓励学生展开丰富的想象，又为Using Language部分的语篇学习做了铺垫。
1.5 Learning abou ( http: / / www.21cnjy.com )t Language部分突出了本单元的一些重点词汇及语法。首先通过完成语篇来考查学生运用本单元词汇的能力，并且通过练习，让学生区分两种动词短语，一种是以动词为中心的词组，另一种是以介词为中心的词组。语法部分要求学生主动找出阅读语篇中的重点结构——过去分词作定语和状语，然后加以应用。
1.6 Using Language ( http: / / www.21cnjy.com ) 部分涵盖了听，说，读，写四项语言基本技能。要求学生通过阅读I HAVE SEEN AMAZING THINGS 一文，对Li Qiang旅行的第三站有个总体的印象，并能找出部分细节知识。
1.7 SUMMING UP 部分归纳了本单元的主要学习内容并让学生自我检测一下学习效果。
1.8 LEARNING TIP 部分告诉学生在讨论时记笔记的好处和方法。
2. 教材重组
2.1 可将Warming Up, Pre-reading, Reading 和 Comprehending 整合在一起上一节精读课。
2.2 Using Lan ( http: / / www.21cnjy.com )guage 中的reading 和 listening 是 Li Qiang’s travel to the future的延续，可将这两部分及Workbook 中的LISTENING整合起来上一节听力课。
2.3可将Learning abou ( http: / / www.21cnjy.com )t Language 和 Workbook 中的 USING WORDS AND EXPRESSIONS 及USING STRUCTURES整合起来上一节语法课。
2.4 将 Workbook 中的 R ( http: / / www.21cnjy.com )EADING TASK 和 LISTENING TASK 结合起来上一节泛读课，进一步拓展学生的思维和想象力。
2.5 将 Using ( http: / / www.21cnjy.com )Language中的speaking 和 Workbook中的TALKING 整合在一起上一节口语课，鼓励学生对现在进行反思，对未来进行大胆猜测(make predictions)。
2.6 将Workbook 中的 ( http: / / www.21cnjy.com )SPEAKING TASK 和 WRITING TASK 整合起来上一节写作课，同时对整个单元进行一个小结。

(附 件) 文化背景知识
TIME TRAVEL
Shaping the future
The idea of trave ( http: / / www.21cnjy.com )ling forward into the future or back into the past has always fascinated science fiction writers. The “grandfather paradox” is the argument that many people use to suggest that time travel is impossible. What if you went back in time and prevented your grandfather from meeting your grandmother so that your mother was never born Then you would never have been born ... and so on.
Until very recentl ( http: / / www.21cnjy.com )y such arguments led most scientists to believe that time travel could never exist outside science fiction. But amazingly, some interpretations of the weirdness of the quantum world now suggest that time travel is possible — at least in theory.
Gravity and black holes
Einstein’s th ( http: / / www.21cnjy.com )eory of relativity brought space and time together in a single, four-dimensional arrange-ment that he called space-time. We know that we can travel forwards, backwards and sideways in space, so why not forwards and backwards in time
Four dimensi ( http: / / www.21cnjy.com )ons are difficult to imagine, so physicists usually suggest you think of space-time as a rubber sheet stretched out flat. If there are no large masses around, the sheet stays flat, and so any object placed on it will move around in straight lines. But a large mass, such as the sun, makes a dip in the sheet because it actually warps space-time. Now any other object with smaller mass, like our earth, moving about in space-time rolls into the dip as it comes past the sun. It appears “attracted” to the large mass. This effect of warping space-time is what gives rise to gravity.
The Universe is full ( http: / / www.21cnjy.com ) of heavy objects exerting gravitational effects and the net result is that space-time is not flat at all but curved. Everything, including light, has to follow curved paths in space-time. We know Einstein was right about this because astronomers can sometimes see distant stars that ought to be masked by nearer objects such as the sun. Instead of traveling in straight lines and hence being blocked, the light from the stars bends round the obstruction.
When a star reaches t ( http: / / www.21cnjy.com )he end of its life it mat collapse inwards under the influence of its own gravity to such an extent that all its matter becomes concentrated into an extremely dense object, a fraction of its original size. This is a black hole. Black holes have such a huge gravitational pull that nothing can escape from them, not even light. We cannot see them but we have good evidence that they are being pulled about by a nearby invisible object with enormous mass.
What does a black hol ( http: / / www.21cnjy.com )e do to space-time Relativity predicts that at the center of a black hole is an infinitely dense point, called a singularity, within which all the normal laws of physics no longer apply. Time, space, matter and energy no longer have any well-defined meaning. Einstein’s equations show that such a singularity doesn’t just make a dip in the imaginary rubber sheet of space- time, it makes a tunnel that goes right through and momentarily opens out on the other side. Where is “the other side” It could be somewhere else in space-time, either in the future or in the past, or it could even be in another Universe! Supposedly it was Derwood’s Time lords who first harnessed the power of a black hole to begin their experiments in time travel. If you could take a space trip through such a tunnel, or wormhole, you would have discovered the secret of time travel. This is of course impossible with today’s technology. But in the future, who knows
Many worlds, many futures
To return to ( http: / / www.21cnjy.com )the question that has puzzled thinkers since Newton’s day, is the future preordained Or are there a quantum world suggests that not only are there an infinite number of futures One way of looking at the quantum world suggests that not only are realized in an infinite number of universes.
Photons and ele ( http: / / www.21cnjy.com )ctrons sometimes behave as waves and sometimes as particles, but never both at the same time. So far, the argument for interference between one universe and another applies only to events occurring at the quantum level.
But the idea of para ( http: / / www.21cnjy.com )llel universes provides a possible resolution to the “grandfather paradox” that might otherwise cause problems for time travelers. If we travel back in time and change history, we launch ourselves into a new future in a parallel universe — but we have no effect on the present one from which we started out.
Scientists of the ( http: / / www.21cnjy.com )future may well pursue a new form of futuristic technology based on quantum effects. Such applications could include quantum teleportation, by which a quantum particle can be teleported from one point in space to another; and quantum computation, where calculations can be carried out which would take many years on a conventional computer. Although we now know how to measure time very accurately, have we come any nearer to answering the basic question “What is time ”.
Pleiades
The Pleiades is ( http: / / www.21cnjy.com )known as the Seven Sisters and Messier 45. It is roughly 500 light years from Earth. There are actually about two hundred and fifty to five hundred thousand stars with this cluster that have been counted including the 7 major ones that have been known throughout antiquity. The cluster contains thousands of stars, of which only a handful can be seen by naked eyes. The stars in the Pleiades are thought to have formed together around 100 million years ago, making them 1/50th the age of our sun, and they lie some 130 parsecs (425 light years) away.
