PRESENTATION & REVISIONWe all know that science is very important in our daily life. Many scientific achievements have changed

8、 our life. They have made our life happier, easier, and more convenient. Today well begin to talk about science and some scientific achievements.2. WARMING-UP Introduction The objective of the warming up activity is to get the students to think about how scientific achievements affect society. The s

9、tudents are asked to rank the achievements mentioned in order of importance and give reasons for their choices. They are then asked to think of other achievements and to try to determine what they may have in mon.Instructions Make sure that the students know what these achievements are (in general t

10、erms). Put them students in pairs or small groups and ask them to decide which achievement is the most important and to give at least one reason for their decision. Ask some (or all) groups to report their decisions and pare different answers. Ask the class as a whole to think of what scientific ach

11、ievements may have in mon. Encourage the students to think of their own reasons and ideas.Suggested answers to Question 1: Various answers are possible.

LISTENINGIntroduction The students will hear about famous first words, ie words that were spoken at important points in the history of science.Instructions Before you play the tape, you can ask the students to read through the

17、questions and see if they know or can guess at which event the words were spoken. You can also ask them if they know any other famous first words.LISTENING TEXT:Part 1Thats one small step for a man, one giant leap for mankind. These were the words spoken by Neil Armstrong, the first man ever to set

18、foot on the moon. Some words bee famous because they are spoken when a great new scientific achievement is being announced or made. These famous first words arent always beautiful or wise, but we remember them because of the important discovery or achievement that they belong to. Another example of

19、famous first words are the words spoken by Alexander Graham Bell when he made the worlds first telephone call. Mr. Bell used his new invention to make a call to his assistant, Mr. Watson_ When Mr. Watson picked up the telephone, he heard Mr. Bell say Mr. Watson, e here; I want you. Perhaps the most

20、unusual famous first words, or rather word, is the worlds first e-mail message. In 1971, an engineer named Ray Tomlinson sent a message from one puter to another. Mr. Tomlinson doesnt remember the exact message, but he thinks it may have been QWERTYUIOP.Part 2Words can also bee famous because they a

21、re used in important documents. The words We, the people are the first words of The Constitution of the United States of America. Other words have been made famous through stories about great events. These stories are perhaps not always true, but the words have bee part of history anyway. One such s

22、tory is of the Greek scientist Archimedes. Archimedes is said to have discovered an important law of physics when he was taking a bath. Watching the water of his bath on the floor, he said Eureka, meaning I have found it. Of course, perhaps the most famous and important words in the world are the fi

23、rst words a baby speaks. Proud parents often tell their friends about the important event, but mothers and fathers seldom agree on what the first word was. Depending on who you ask, that word is either. well, can you guess?Answers to the exercises:Part 11 First man on the moon. 2 e here First teleph

24、one call. 3 First e-mail message.QWERTYUIOP are the first keys on a keyboard. When Tomlinson wanted to send a test message, he sim:. ply typed in the first letters on his keyboard.Part 21 We. the people: first words 2 Greek, I have found it 3 Daddy.; MommyPart 3Various answers are possible. Sample a

I take this step for all of you back home.Did I turn off the gas 1B I have no mother or father, but you are all my family.I am the child of human creativity and science. Hey! That guy looks just like me!C I have gone where no one else has gone

26、before. Greetings from the future.Hello. When am 11Whoa! I must have pressed the wrong button. Run! That dinosaur looks hungry!4. SPEAKINGIntroduction This is a decision role play similar to those found in books lA, IB, and 2A. The students are asked to work in groups of five and try to decide which

27、 project should receive the money.Instructions Like most decision role plays, this activity has three basic steps. First, explain the scenario and task to the students. Model a few examples if necessary. Tell them that they will work in groups and that each group member will represent one of the pro

28、jects. Second, divide the students into groups and tell them to choose roles and prepare role cards. The students should not write down what they are going to say, but they may want to make a few notes. When all members are ready, the students will start the discussion. The teacher monitors and inte

29、rvenes only when absolutely necessary. Third, each group will report their decision to the class. The teacher asks questions and helps the class pare different decisions.Sample discussion:A: Good afternoon. Since all of you have asked for money to pay for your projects, I would like to hear from eac

30、h of you. Please tell me about your project and why it is important. Lets see, would you like to begin?B: Thank you. My name is Dr Wilson. My team and I are working on a cure for AIDS. As you know, AIDS is one of the most serious diseases in the world.Some 40 million are infected with the disease, m

31、illions are dying from it, and many more will bee infected in the future unless something is done. Our research is extremely important because a cure for AIDS would save the lives of millions of people. It would also help poor countries. In Africa, some countries are suffering from the disease in ma

32、ny ways; people are dying, of course, but the disease is also destroying the economy. If I got the money, I would continue our research and try even harder to find a cure.A: Thank you, Dr Jones. Dr Jones, please tell us about your project.C: Good morning. I agree that a cure for AIDS would benefit a

33、 lot of people. But lets not forget that there are many other diseases that we arent able to treat or cure. My plan is to start a project about cloning and how to use the new technology to cure disease. My project is significant because it may lead to the development of new drugs and treatments for

34、a number of diseases. I hope that you will give us the money we need so that we can help all the people in the world who are suffering from diseases.A: Thank you, Dr Wilson. Who would like to be next?C: Im Dr Smith and I want to develop new technology that will make it possible to g-row food in area

35、s where there is very little water. This is important because the worlds population is growing and we need to make sure that there is enough food for everybody. At present, many poor countries suffer because they dont have enough farmland. Our project can help them. With the new technology, land tha

36、t was useless before can bee a valuable source of plants and crops. I intend to develop and test the technology in one country and then share the technology with the rest of the world. By helping us, you are helping the whole world prepare for the future.A: Thank you. Dr Winfrey, please tell us abou

37、t your project.D: Id like to develop a way to send a manned space ship .to Mars. My colleagues have described their projects, and I must say that I think all of them are important. But, in my opinion, the money should be given to the project that is likely to lead to the most up-to-date discoveries.

38、 I agree that finding a cure for AIDS is important, but how would it help us advance science? I also agree that cloning may help doctors, but the basic technology has already been developed. As for growing food in dry places, that would be great, but, again, I dont see how it would benefit science.

39、Our project, on the other hand, will lead to new inventions and discoveries that can change science forever. To send a man to Mars, we must solve problems that have been Considered impossible. When we reach Mars, we will learn new things about the universe. If you give the money to us, you are givin

40、g money to science and to knowledge.The discussion continues.5. SUMMARY & HOMEWORK1. Preview the reading text2. Learn the new words and expressions by heart.3.

42、nge friends. Can you tell me what can be your good friend besides a person?2. PRE-READING Introduction Relating what one reads to what one already knows is an important part of the reading process. Reading prehension is not simply a matter of translating or decoding a text; it s a plex process that

43、involves skills, strategies, and logical thinking. In this pre-reading activity, the students are asked to apply what they have learnt in the previous activities to a new set of questions. Through further discussion of the questions raised in the Warming Up and Speaking, the students are given an op

44、portunity to deepen and broaden their understanding of the theme of the unit.This unit introduces several aspects, concepts and issues related to science and scientific achievements. A special emphasis is placed on the role and function of science in society, and the interaction between science and

45、society. The pre-reading questions are intended to help students identify and focus on some of the issues raised in previous activities (e.g. the Warming Up and Speaking) and prepare them for the Reading and Integrating Skills.Question 1 asks the students to consider how society makes science happen

46、, i.e. how we train and support scientists. Question 2 echoes the Warming Up and asks the students to identify ways in which scientific achievements contribute to and improve society. The third question encourage the students to think about why scientists work so hard and sometimes devote their live

47、s to science.Instructions Ask the students to discuss the questions in pairs or small groups. To save time, you can assign one question to each group. pare and discuss answers.Answers to the questions:Various answers are possible.1 A person who wants to do research or start a hi-tech pany may need t

48、he following: money, schools, libraries, scientists and experts, ideas, inspiration, etc.2 Scientific achievement are important because they help people understand the world better / improve our life / help advance science / lead to new discoveries and achievements.3 Scientists spend so much time tr

49、ying to achieve something because they are curious and enthusiastic about new things and new ideas / they want to understand the world better / they want to contribute to society / they want to be rich and famous.3. READING Summary The reading describes Zhongguancun and provides brief background inf

50、ormation about the science park. The park was set up in the late 1990s and is now the leading centre of Chinas hi-tech industry.The reading also includes the fictional story of a Chinese scientist who returned to China after studying and working abroad. Xiang Yufang (not a real person) wanted to liv

51、e in China, but couldnt find a good job until he heard about Zhongguancun. He returned to China and is now running a small pany with two friends. The story illustrated both the relationship between society and science discussed in pre-reading.Question 1 (and, to a lesser extent, Question 3) and the

52、attitude of many overseas Chinese. The right support and environment (as described in Paragraphs 6 and 7) allow scientists to do their work successfully. The intellectual support, i.e. the spirit of a science park like Zhongguancun (see Paragraphs 6 and 7), can also be the deciding factor when a sci

53、entist is looking for a place to work. For many scientists, perhaps especially those who have had to find work overseas, the environment and support may be even more important than money.The chart shows the education of the people who work in Zhongguancun.4.
