Ⅰ單元教材內容分析
當全世界科學技術發展迅猛，各種發明創造層出不窮，是因為人的思維品質與思維方式即（creative thinking）對發明創造起著至關重要的作用。因此培養學生的探究性思維能力，創造思維能力是時代社會對教育的要求。教師在課堂教學設計中力求體現“開放、啟發、引導、自主”的教學原則，幫助學生運用相關的詞匯表達自己的思想及思維過程，培養學生用英語描述某一發明創造，如構造的工作原理、用途等的能力。況且，我們曾經在高一（上）Unit9 Technology，高二Unit 1 Make a Different, Unit 6 Life in the future, Unit 11 Scientific achievement 等單元中已積累一些詞匯。
本單元的中心話題是：“發明”（Inventions），課文始終圍繞這一主題展開。具體涉及“科學技術發展”、“人的思維”、“創造性思維及其品質”、“對發明的新認識”等，語言知識和語言技能部分主要是圍繞“發明創造”這一中心話題時行設計的，要不斷豐富鞏固這一話題的詞匯及習慣短語。
“熱身”（Warming up）部分設計了三個練習，列舉了四件與學生日常生活聯系密切的，富有啟迪意義。
“聽力”（Listening）部分提供了兩人申請發明專利的情景。兩項發明均未被接受。學生一方聽懂兩項發明，而且還要判斷發明是否有用。這個聽力練習要求學生運用聽的技能的同時，還要學生思考、分析和解決的問題。
“讀前”（Pre-reading）部分設計了三個問題，這三個問題的設計提供給學生開放性的思維，可以利用“頭腦風暴”（brainstorming）讓學生展開思維，闡述自己的觀點，為正文的閱讀作好語言鋪墊。
“閱讀”（Reading）部分介紹了偉大的思想家產生新發明的一些思路和思維模式：框外思維、換個角度看問題、聯想和不斷試驗。安排這篇文章的目的在于培養學生的創造性思維。這是一篇說明文，可以用來幫助學生學習說明文的結構。
“讀后”（Post-reading）部分是在閱讀的基礎上，通過兩個活動，檢查學生的理解程序，誘導學生聯系實際，拓展思維。問答題的設計從表層引入深層、由課文導向課外。第一題為判斷題，主要檢測學生對文章細節的理解和掌握。第二題實際上為文章提出的發明創造的思維模式列舉了具體的例子。
“語言學習”（Language study）分詞匯和語法兩部分。詞匯部分設計了兩個練習，其目的是幫助學生復習所學過的詞匯（包括詞性和詞形）及短語。語法部分圍繞定語從句而展開，而且選用了謎語，生動有趣。
“綜合技能”（Integrating skills）部分有閱讀和寫作兩個任務。閱讀的文章說明科學隱喻（運用通俗的名稱于新的發明之中，如電腦中的memory，storage和paste、print等等）的作用及其局限性。寫作題有兩個：“未來的電子計算機”和“向十九世紀的人介紹電腦”，由學生選作。這個任務符合學生的年齡特點、貼近現代生活，能夠引起學生的興趣。
“學習建議”（Tips）介紹不同的學習策略，如聯想、猜測、圖示以及分析錯誤等。
“復習要點”（Checkpoint）復習了定語從句。同時通過兩個問題引導學生對本單元所學的內容 進行一次反思。
II 教材內容處理
1、本單元教材重難點處理
我校大部分學生具有較充分的閱讀詞匯，但學生語法知識，口語表達能力較弱，用英語思維表達的習慣很弱。學生具有一定的自學能力，學校局域網健全，并配備學生專用電子閱覽室。這些使學生的自主探究學習成為可能�；谏鲜鰧W生情況，我列出本單元4項重點和4項難點。旨在突出圍繞本單元課題的詞匯，獲取文章大意的閱讀能力及闡述觀點的能力，以培養學生聚合思維和發散性思維，從而達到培養學生Creative thinking way，這也是本單元的教學目標之一。在word study 課時中把重點放在學生自我發現、練習鞏固上，講練結合，當堂鞏固。在定語從句復習與寫作訓練中，以圖式理論為指導，采用分類列舉法幫助學習記憶語法規則，用列表法為學生提供必要的說看材料，讓學生擴展成文。同時，以“引導、鋪墊、分散、突破、反饋”為原則，處理課堂教學任務；以分組合作，筆頭記錄、口頭匯報的方式反饋兩項主題活動，這也是本單元2個非常重要的預習作業；以測試性評價手段，借助多媒體來鞏固構詞法、定語從句和本單元的重點詞匯。在整個單元教學中，始終堅持任務目標，材料輸入（導說領先），活動或討論，筆頭落實，環環相扣。碰到一項較難的任務時，以教師提供幫助或教學內容在教學程序上的鋪墊來減輕任務的難度，從而使大部分都能獲得成就感。
2、教材運用的改編或增減
增加部分：增加構詞法的練習鞏固

V 單元課時教學設計
Period 1 Warning up ＆ Listening
Period 2 Speaking ＆ Talking
Period 3 Pre-reading & Reading & Post-reading
Period 4 Language study ＆ Practice
Period 5 Integrating skill ＆ Writing
Period 6 the Revision of the Attributive Clause (possible)
Period 7-8 the two periods for exercises
Period 1 Warming & Listening
Goals 1. Improve the Ss’ listening ability.
2. Enable the Ss to get involved in the topic and familiar to some new words and expressions.
Step1 Lead-in
Today’s topic is invention.
When we speak of invention, we can’t help thinking of the four great inventions in ancient China. What are they? Meanwhile， with the development of science more inventions have come about. These inventions are wonderful.
T：Now what invention do you think is the most useful? Why?
Ss: Collect the Ss’ opinion
T: But some inventions are so common that we often forget how wonderful they are. For example, zippers are very useful, but they are forgotten. Almost none of us know who invented them. Do you think so? Do you think it is important to know how things were invented?
If you want to invent something, you need to train yourself to have creative thinking to think about them in a different way based on the present things.
Now let’s do some riddles to see how clever you are? (on the screen)
1. What is it that Adam has none Eve has two and everyone has three?
2. What is it that the dead eat and that the living would die if they ate.
3. What is it that you use your head to your toes and the more it works the thinner it gets.
4. What is it that is not an airplane but moves through the sky not a river but is full of water?
Step 2 Warning up and discussion
Let the Ss look at the pictures to tell anything special about each picture and then ask the Ss to match each picture with the correct description below.
Ask some questions:
1. What kind of shoes is it? Is there anything special with the shoe?
2. In picture2 the chopsticks can be eaten.
Which word means eaten? edible chopsticks
3. What does nose-top computer mean?
How can you use it?
4. What does “inflatable bike” mean?
What are the advantages of bikes of this kind?
Discussion:
1. Which of these inventions do you think would be useful? Why?
教師可以幫助學生運用：I think ** would be the most useful invention because by using **, we can …
2. Is there anything you would like to invent? If so, what and why?
Possible sentence: I would like to invent a multi-use car. The multi-use car is a new type of car which can pass through any place when it is crowded. For example… You will never be late and save a lot of time for you.
Step 3 Pre-listening
We know when someone has invented something, usually he will go to a patent officer to apply for his patent. Now let’s listen to two dialogues.
In the dialogues, Mr Dean and Mr Scoles both have invented something. They’re trying to get the patent for their inventions from the patent officer. Let’s go through the questions on P15 first and then do the listening.
Step 4 Listening
Play the tape twice for students to listen to and them answer the questions. Play it a third time for the students to check their answers in pairs. At last check the answer with the whole class.
Blackboard:
Creative thinking
edible chopsticks
environmentally friendly(read-friendly)
inflatable
apply for 申請（vi） apply 應用（vt）
apply for a patent for sth
the patent officer
give a patent
hold a patent
step6 Assignment
1. Find out as many inventors as possible and try to describe one of most important inventors you think to the class, using the attributive clause if possible.
Period2 Speaking & Talking
Goals: Expand the topic around inventions to develop the Ss’ creating thinking and speaking ability.
Step1 Lead-in and reporting
T: Well, let’s begin our lesson. So far we’ve known some inventions and their inventors. Who is your most admirable inventor. Please describe something him or her to the class? Anyone will be the first?
Invite the some individual to report their preparations one by one.
Step2 Talking
T: We know inventions are important and great. It seems a little difficult to invent something. But do you think it is always difficult to think of something special?
S: No, sometimes it is not so hard to think of “A smart something”. And in our real life. We can create many smart things, for example, a smart refrigerator can tell you when you need to buy more milk or eggs. A smart air-conditioner can change the temperature itself when it is becoming hot or cold.
T: What smart objects can you think of ?
Ss: Collect Ss’ ideas and then let the Ss turn to P131 Ex.1 and choose two of the smart devices below and have a discussion with your partner to see how they could be used and then decide one to give a report.
Smart money Smart shoes Smart basketball Smart clock Smart pen
Smart car Smart medicine Smart bike Smart heater
Step 3 Speaking (role-play)
From the last lesson we also know how to apply for a patent. Now you are in a patent office. Let’s play a game. Each of you will be given a role card work in groups of five: four inventors and one patent officer. Each inventor should explain how the invention works and why it is useful. The patent officer should ask question and decide whether each invention is a good or not. And I’ll show you some useful expressions to help you. In the end show out some example dialogues.
This invention can help people…
This new invention will make it possible for people to…
This is a new way of…
It has many functions like…
What does it look like…
What’s it make of…?
How does it work…?
How would people use it ?
What are some advantages compared to other product of this kind?
專利官員評判時可使用以下句型:
1. I’m much impressed by ________
2. I think your invention is ____________
3. That’s really a good idea ___________
4. I’m afraid it might not _____________
5. I’m sorry ,but I can’t give you a patent for
6. I think you can have the patent for ________
Possible examples：
A=Patent Officer
B, C, and D =Inventors
A: Good morning. Please tell me about your invention.
B: Yes, well, I have invented a car that uses water instead of petrol. This invention is great for the environment. Imagine how nice and clean our cities would be if we didn’t have all the air pollution from cars.
A: Yes, it does sound good. How does it work?
B: Well, I can’t explain the details, but it uses a new kind of engine that can turn water into energy. The new engine is a bit expensive, and the cars won’t be able to drive very fast, but I think it will become cheaper with time. It is a new way of producing energy, so we will have to build new cars. It can’t be used for normal cars.
A: I see. What about your invention?
C: I have invented a machine that makes it possible for people to know the future.
A: That sounds incredible! How does it work?
C: It’s a small computer that is connected to your brain. It uses everything you know, and all the information on the Internet. Then I use a special equation to guess what will happen next. The machine is right almost90% of the time.
A: How would people use it?
C: Well, let’s say you want to know what questions will be on the maths test next week. You ask the computer to guess and it will predict the questions. Or, if you want to know what will happen two weeks from now, you just type in the date and the computer will describe what will happen to you.
D: Excuse me, may I tell you about my new invention?
A: OK.
D: I have invented a flying bicycle. This invention can help people get around in crowded cities.
A: What’s it made of?
D: The bicycle is made of very light plastic. The bike doesn’t weigh more than 50 grams.
A: And how does it work? What does it look like?
D: There is a small engine on the bike----it looks a bit like a helicopter. If you want to fly, you just start the engine and take off.
( The discussion continues.)
Step 4 Extensive Listening practice (part 1)
Go through Ex.1 on P130 and do extensive listening practice for exact information
Step 5 Summary
Today we’ve learnt how to express and support an opinion. And we’ve learnt how to apply for a patent when you have made an invention. Many of you have wonderful ideas about new inventions. Study hard now and I believe you’ll make your own invention in the future.
Step6 Assignment
1. Preview the text and learn the make out difficult sentences new words and expression.
2. Draw your invention and to apply for a patent, please give a good description to it, including how it looks, how it works, and how people can use it.
Period 3 Reading
Goals: 1. Learn the text and train the Ss’ reading ability.
2. Learn some useful words and expressions.
3. Help the Ss to learn to be more creative.
Step 1 Lead-in and Pre-reading
T: Greeting and ask:
In modern times, we have so many inventions? What inventions have you known?
Yes, the inventions can make people’s life easier and better. They will do a lot of good to people.(on the screen)
① But how do they come up with ideas for new invention.
② Do you think you have to be very intelligent to be an inventor?
③ Are some people born creative or is it possible to learn to be creative?
If you want to be an inventor yourself, you must have a lot of questions. New read the passage quickly to find the answers to these questions above.
Step 2 Reading
Allow the Ss a few minutes to find the answers to the questions.
T: Are you finished?
Ss: Yes.
Then collect different opinions from the Ss.
Focus on:
1. Why is it possible to learn how to be creative?
Because creative thinking is a matter of habits. By thinking about how we think and practising good thinking strategies. We can become more creative.
2. Why people don’t have to be very intelligent to be an inventor?
First he or she should be intelligent. But not very because only some of the thinkers did well in school. And creativity is not about getting high test scores having a high IQ or being smart
By the way, what does EQ stand for?
3. Guide the Ss to say out the following points.
① People should try new ways to solve a problem and break away from old thought patterns.
② People should try to combine new with old ideas in many different ways as possible. By comparing and connecting ideas and objects in new ways. People may think of new application and solutions.
③ Good ideas are no accident. They are the result of a long process of trial and error. So keeping trying is important. Failure is the mother of success, as we know.
Step 3 Careful reading
As paragraph one notes, great thinkers seem have little in common-----they have different backgrounds, IQ and education. What they do have in common are the thinking habits outlined in the reading?
1). What are their thinking habits according to the text?
Can you find a sentence from the passage to explain each thinking habit?
2). What’s creative thinking?
3). If we keep trying some of the thinking strategies of the great and famous, what may be the result ?
4. True of False: Do Ex1 of post-reading On P60.
Step 4 Explanation and Listening

Period 5 Integrating Reading & Writing
Goals: 1.Learn a reading passage to improve the Ss’ reading ability and learn about science metaphors.
2. Do writing practice to improve the Ss’ ability of writing a process essay around computer.
Step 1 Lead-in and talking
T: How many of you have a computer at home? Please put up your hands. Who do you do with your computer?
S: I search for information on the Internet.
Play games with it.
Draw picture or type a file.
Send e-mails to friends.
Listen to the music.
Watch football matches.
Read books on the Internet.
T: Yes, we can do these things mentioned easily depending on computers. But we can also do these things without a computer.
S1 we can go to library to look for the information needed. But it’s much quicker and more convenient if we use a computer as a typewriter to type letters
S2 Listen to music on the tape recorder.
Watch football matches, on TV, etc.
T: You’re quite right. Now technology is often used in old ways. That means we can use some old words to describe new technology and science for example “store, memory, cut, paste”. We call these science metaphors. Now please have a discussion in groups of four to complete the chart shown on the screen.
The Internet: used as a library/ TV/ telephone P
used to send e-mails
read news from home and abroad
Cellphone: used as a telephone/ a telephone directory/ a video game player
a watch/ a calender/ a alarm clock/a torch
Step 2 Reading
T: Well done Now we are going to read a passage about science metaphors. Turn to P62 and try to find out the answer to the two questions.
1. Why are scientific metaphors like “memory” and “cut and paste” useful?
How many they limit our thinking?
Answer: They make it easier for as to understand and use a new tool. They may make it more difficult for us to use the new invention in the best way.
2. Think of more words we use to talk about computers and Internet. How well do they describe the things or action they are used for? Are there other words we could use tat might be better?
copy, file, delete, lock, enter, return, store

Samples:
Have you ever seen a computer?Now let me tell you something about the computer. A computer is an electric calculating machine that can store and recall information and make calculations at very high speed. It is a wonderful machine and can do most of the things people can do, but it can work millions of times faster. The first large, modern computer was built in 1946, and people needed a large house to put it in. In the last few years there have been great changes in computers. Today they can be used in many fields. People even use it to pay their bills or order what they want . It is said that in the future computers would arrange everything for people, and do almost all kinds of work. That would be a real computer society! I believe that the computer will sure become smaller and smart, which you take where you go.
