Step 1 Presentation
When you are talking about studying, almost all of you think that studying can only happen in the classroom, and it only means listening to the teachers’ explanation. But there can be many means to study. For example, studying in the lab, reading the books by yourself. Now turn to page 22. And try to describe the four pictures listed in your text book.
2. After describing the pictures, let the students answer the following question.
(1) What are the names of the school subjects in which you study sciences?
(2) Give an example of what you learn about for each field of science.
(3) What are the rules when you do the experiments in the lab?
（三）教学过程
Step 2 Warming up
Suggested answers for Question 1:
I Photo 1 shows students at work in a chemistry lab.
2 Photo 2 shows an English book called Hamlet, a dictionary and a notebook.
3 Photo 3 shows two students doing an experiment.
4 Photo 4 shows students looking at something through a microscope.
Suggested answers for Question 2:
1 Chemistry 2 Physics 3 Biology
Suggested answers for Question 3:
1 In chemistry we learn about the way different liquids and materials react with each other. For example, if you put a piece of metal into a glass containing a strong acid, it will dissolve.
2 In physics we learn about the laws of the universe, for example about Newton and the reason why all things on earth fall down.
3 In biology we learn about life on earth, for example by looking at the structure of cells.
Step 3 Listening comprehension
Now let s have some listening training.
Listen to the tape and try to answer the exercises. Tell the differences between the rules they have talked about and the one listed in the tape. Then get to know the important to keep safe in the lab.
LISTENING TEXT
MR DENG: Everybody listen carefully! Today Mrs. Zhu will explain about the safety instructions for the lab. If you have any questions, you can raise your hand.
MRS ZHU: For experiments that are done in this lab, everybody should remember: Safety comes first! This is very important, because the experiments are fun and very interesting, but we don't want any accidents. First of all, don't come in here without your teacher. Once you're in here, follow your teacher's instructions. When you come into the lab, students with long hair should tie it up, or put their hair under their clothes. Always listen carefully to your teacher's instructions and don't touch anything, unless your teacher tells you to.
MR DENG: Can you explain a bit more about doing experiments?
MRS ZHU: Sure. Never put your nose directly into a glass or over a bottle. Gases can be very dangerous. Instead, you should wave some air in your direction and carefully smell it. Never put your fingers into glasses and never taste anything! When working with fire, be careful about the flame. When working with electricity, make sure your hands are dry. When anything gets into your mouth or eyes, immediately wash with a lot of water. Remember that the classroom isn't a playground. Don't throw i things or start playing. That can be dangerous.
SUN YAO: What about when we leave?
MRS ZHU: When class is over, clear everything away and leave the classroom neat and clean. Before leaving the classroom, wash your hands with water and soap. Don't forget to turn off the lights and shut the windows.
Answers to Exercise 1 :
safety in the lab, experiments, long hair, gases, flames
Answers to Exercise 2:
1 Safety comes first!
2 Follow the teacher's instructions.
3 Bottles may contain dangerous gases.
4 Immediately wash your eyes with a lot of water.
5 Clear everything away and leave the classroom neat and clean. Wash your hands with water and soap. Turn off the lights and shut the windows.
Step 4 Speaking practice
Talk about the effect of the science of technology. Let the students know the application of science and technology does good to our society , at the same time , it also harm to the human beings or the environment.
Practice in pairs to talk about some advantage and disadvantage of the scientific discoveries and applications listed in the book.
Sample chart:
Invention Advantages Disadvantages
Cloning 1 can help some women have babies 1 it is not natural to make people
2 can help medical research 2 dangerous; people use it to do strange things
1 can make all the electricity we need 1 unsafe to all life if not controlled
Nuclear energy 2 is a limitless resource 2 can be expensive to build / repair
1 makes communication faster 1 unsafe because of viruses
Computers 2 can keep information better 2 makes more problems than it solves
Space flights 1 makes research of outer space possible 1 expensive and dangerous
2 put communication satellites in space 2 used by the army
Sample dialogues:
Cloning:
A: Cloning is one of the most important discoveries of our times.
B: I think it should be forbidden. It's dangerous and it's unnecessary.
A: What do you mean? It's great if we can clone people. It's a way to make people, so women can have babies but they don't need to give up their jobs.
B: But don't you think it's wrong to sort of make people? It's unnatural. And besides, some people will use it for other things.
A: I don't think so. Cloning can be useful to the development of medicine and make the life of women more comfortable.
B: No. You should think of the dangers. People will use it to create people and use those people as slaves.
Nuclear energy:
A: It's been known for many years that we can't go on using coal and oil for fuel. They pollute the environment too much. Nuclear energy is the best way to make electricity. It's clean and it doesn't pollute the air. It can help many people in the future.
B: It's true that it doesn't pollute the air, but it isn't clean. Nuclear waste is very dangerous for your health. Accidents in nuclear energy plants can kill all life on the planet. These places aren't really safe, you know.
A: I think you worry too much. Electricity from nuclear energy is cheap and that is good for the economy.
B: I don't believe it can be cheap. These factories are very expensive to built, to keep working safely and taking care of their waste is also very expensive. Nuclear waste is very bad for the environment.
A: Well. What do you want to use instead of coal and oil for fuel?
B: Nuclear energy is unnecessary. People can use water power and the sun to make electricity.
Computers:
A: Computers are very useful and can help people in the future even more.
B: I agree. But there are also disadvantages.
A: What do you mean?
B: Well. Just think about it. Who makes computers? People do. Right? And because the people who make computers can make mistakes, we can't rely on computers.
A: I see your point. But what problems will they cause?
B: Who knows? Maybe they will make people lazy. Maybe they're unnecessary for doing some jobs.
A: I don't agree that they're unnecessary. I think computers are important for science, especially for medicine. There is no doubt about it. Computers can store a lot of information and it's very easy to find information. .With computers people can work faster. Today one man working with a computer can do the job of ten people in the past. That's good for the economy.
B: That's true, but for common people they're still too expensive.
A: I agree. But I'm sure they'll become cheaper. In the future we'll all be using computers every day, and they'll bring people more comfort.
Space flights:
A: China is the third country in the world that has sent a man into space. Isn't it Great!
B: Yes. It's a great achievement. I'm sure it's very important for science, but on the other hand, such space flights are very expensive.
A: That's true. But you mustn't think of it in that way. Think of all the new discoveries that will be made during space flights!It can help many people in the future. China can put satellites up into space that we need for communication.
B: Well. I still think they're too expensive. The space programme costs too much money and. that money could be spent better on other things. Besides, I'm sure these discoveries you are talking about can also be made on earth. So space flights are unnecessary.
A: Well. Aren't you proud of our nation's space programme?
B: Sure I am. But that does not change my mind about the advantages and disadvantages of space flights.

In this class we’ll first go through the text and learn to use some language points. And then we’ll discuss the exercises together with each other. After having learnt many words, we find that some words have more than one part or speech or a meaning. For example, bank can lean not only the ground near a river, but also the establishment for keeping money . It is one factor of words and we may find that if some words are combined, a new word come into being. Today we’ll talk about these two phenomena.

Step 1 Presentation
With the development of medical science, more and more new medicines come into being. But do you know that there are some animal’s contribution to the coming of the new medicine. Because each new medicine must be tested on animals before it is used on human being to decide whether the new medicine can be used. And then many animals die in this kind of experiment every year. So it brings a heated argument. Some are against. Today we will also take part in this debate.
（三）教学过程
Step 1 Question the students on some language points
Step 2 Integrating skills
Read the arguments listed in the textbook. And think it over to decide whether the students are for this kind of animal test. Try to make your opinion solided.
From some groups to debate with each other. Choose some groups to act it out before the class.
Step 3 Listening to the Passage
Step 4 Reading comprehension
After fast reading, do the following True-or-False exercises.
Sample persuasive essays:
For testing:
WHERE WOULD WE BE
WITHOUT NEW DRUGS?
Animal testing is used to develop new medicines to meet the needs of a growing number of older people. These medicines are helping us to live longer and healthier lives. But some activists are trying to change the way we think about new medicines. They are against the use of animals to test these drugs and believe such testing is unnecessary.
Scientists who work in medical labs know from experience that there is a very high chance that medicines that work with animals can also work with people. Sometimes mice are used to begin the experiment, then later dogs and monkeys. Finally, when the scientists are almost sure about the safety of their new medicines, they will ask for humans to help to test them. As we can see, animal testing is a practical, necessary part of the procedure.
However, some people are against animal testing. They believe that it is unnecessary to use animals in testing new medicines because doctors can use knowledge that was gained from experiments in the past. These activists also say animals have the same rights as humans. But what if someone in our family has cancer and our doctor says a new drug might make them better? Do you really think we will care what happens to a mouse?
Some kinds of animal testing on products that make us look better, like skin creams, may really be unnecessary. Yet doctors have a duty to continue to improve the lives of humans first.
Against testing:
STOP THE USE OF ANIMALS NOW!
Every year hundreds of new products are offered for sale in shops. Soap with the smell of watermelons, peach or apples. There will be new food products with funny new colours, smells and tastes. All these new products look beautiful and they taste or smell wonderful. But can you really enjoy using them if you about all the suffering behind them?
Animal testing has helped doctors to develop medicines against many diseases. But is it really necessary to continue developing new drugs for illnesses for which we have already found a cure. For some simple diseases such as a cough or a headache, you can go to a shop and find maybe forty or fifty different brands. All these medicines have been tested on animals and thousands of them suffered pain and died or were destroyed. Why can't people be happy to have a choice of two or three good medicines that cure a disease?
Although animal testing is not as cruel as it used to be, that does not mean we have the right to use animals in experiments. We don't have the right to use humans in experiments because we think human life is of great value and humans feel pain. But so do animals, and their life is just as important as that of people. Enough is enough. Animal experiments should be stopped now!
Assessment criteria:
For assessment criteria for organisation, vocabulary, language use and basics, please refer to the Appendix about writing assessment.
For the content, the students' writing could be assessed using the following criteria:
Does the essay have a clear title that immediately conveys the opinion of the writer?
Does the writer give both arguments for and against animal testing?
Does the writer successfully make the reader feel that we need animal testing?
Does the writer successfully make the reader feel that animal testing is cruel?
Does the writer give enough examples that show that animal testing is beneficial?
Does the writer give enough examples that show that animal testing is unnecessary?
Does the writer give enough examples of products and situation in which animals are used?
Three more examples for each group:
1 Compounds that are written as two words: toy factory, washing machine, apple tree.
2 Compounds that are written as one word: handmade, gunfight, goldfish.
3 Compounds that are written with a hyphen: window cleaner, easy-going, boat-ride.
Give the students some explanations when necessary.
Step 5 Writing
Generalize the students’ opinions and give them the instruction of writing an argumentive essay.
Talk about the advantage and disadvantage of building the three Gorge Dam.

Step 5 Listening to the Passage
Step 6 Reading comprehension
After fast reading, do the following True-or-False exercises.
Answers to the questions:
1 Brown ink is a mix of different colours of ink. When separating these colours, they suddenly come out. When we could not see them, it seems as they were "hidden colours".
2 The colour green is made by mixing yellow and blue. The colour orange is made by mixing red and yellow. The colour purple is made by mixing red and blue.
3 The water should not touch the ink dot because then the ink would get into the water, and the results of the experiment would not be clear.
4 If the experiment does not work, and the ink does not "travel" up the paper strip then there can be two reasons:
1 The ink from the markers does not go up with the water. (The ink is not water soluble). '
2 The paper is not good for this experiment (The paper either does not let the water through or lets the water through too fast.)
5 The police can use this technique by separating liquids such as blood or urine to check whether they contain drugs or poison.
