Do you know the program Lucky 52 on CCTV?Ss: Yeah!T: OK, now suppose I m Li Yong, and you are competitors. Here are sixwords on the blackboard. What you should do is to guess the meanings ofthem. If you cant express them in English, you may say in Chinese. Thequicker, the better. Are you clear?Ss: Yes.T: Listen. What do we take in when we breathe?S1: Air.T: Right. But not exact.S2:氧气。T: Right. In English, it is called“ oxyge n” . We need oxygento keep alive. Andwithout it, there will be no life on this planet. OK, another question. What dowe call it when we put sugar, eggs, and milk together, or we mix themtogether?S2: We call it mixture.T: Good. All the things that are mixed together can be called mixture. Nextone,we can use one word to stand for all the things around us, which includes air,water, stone, wood, glass, iron and so on. What is this word?S3: Substance.T: Right. Next, what will happen when water turns into ice?S4: Liquid will turn into solid.T: Right. Besides this, will it have some change in size?S5: Yes. It will become larger.T: Yeah! What do we call this change?S6: Its called“expand”.Teacher can use body language to express the meaning of“expand”.T: Now, the last one. Whats the opposite meaning of“expand”?S7: Is it“contract”?T: You are right. The meaning of“contract”is making or becoming smalleror shorter. Well, I think that all of us did very well. Now please read thesewords after me.StepnVocabularyAsk the students to read the sentences in Activity 1 on page 41, and thenpick out the correct ones. At the same time ask them to pay attention to thenew words. At last check the answers to Activity 1 with the whole class.For Activity 2, ask the students to work in pairs to finish the task. If possible,ask them to give their rea-sons for doing so. For Activity 3,give the studentsmore words to help them know that materials are around all of us, and weshould use them correctly and reasonably.T: As the saying goes: Birds of a feather flock together or things of one kindcome together. Now well put the words in Activity 2 in pairs or groups, justlike the pairs in Example. If possible, give your reasons to do so. It is a goodchance forus to get familiar with these words. OK, Ill give you one or twominutes to dothe job.Two minutes later.T: Have you finished the task?Ss: Yes.T: Whod like to read out your answers?S1: Wed like to put air, gas and oxygen together, because all of themare gas.And we put earth, sun and moon together, because all of them areplanets.T: Quite right. How about you two boys answers?S2: Weput gas, liquid, and solid together, because wethink they are thethree states of substance. And we also put contract and expandtogether. The two words have opposite meanings.T: I m very glad that you can finish the task so quickly and correctly. Well,allof us know that we are living in a material world. Without these materials,whether natural or man-made, we ll have nothing to eat, to live in, to use,to wear and so on. Now, let s look at these words: electricity, iron, metal,steel, air, and glass in Activity 3. You have to tell which of them are natural,which of them are man-made and which of them can be both.S3: Air, iron and somemetals are natural. Steel, somemetals and glassare man-made. And electricity can be man-made and natural.T: Why do you think electricity is both man-made and natural?S3: Because in a storm, we can see lightening in the sky. While theelectricity weare using in everyday life is from electric works. So I think electricity isboth man-made and natural.T: Well, it s a good answer. OK, can you say some other things that areman-made?Ss: There are too many such things.T: Give us some examples.S4: Cars, machines, man-made satellites, plastics and so on.T: Do you know man-made beauty?S6: I know it. Some ordinary-looking girls can become beautifulovernight.T: Do you think it is necessary to do so?S7: Its difficult to say. But I think to have a beautiful mind is moreimportantthan to have a beautiful appearance.T: I agree with you. It is said that a womanwith a beautiful mind is morebeautiful than a woman with a pretty face.Step 川 Reading (Passage A: P44) There are three activities in this part:Activity 1: find the correct order to describe the stages of a scientificexperiment; Activity 2, find the best title for the passage; Activity 3, answersome questions about the passage.Task 1: Activity 1T: Well, if you were an engineer, you would take part in the experiment ofmakingShen ZhouVFlight. What kind of materials would you like to use?S1: Id like to use some materials that are light enough and hardenough, so that the flight can be easily sent up into space, and doesnt getin trouble.T: How can we find such kind of materials?S2: We can do some experiments. We cant use natural materialsonly; we need both man-made and natural materials.T: Thats right. Now well read a passage about a scientific experiment.Please turn to page 44. Well go through Passage A. When we are doing athing, we should do it in an orderly way. Its especially true with ascientific experiment. Nowlets see the four words in the table: conclusion, aim, result and method.The four words are about the orders or stages of a scientific experiment.Wemust know these two words: result and method. What are the meaningsof the other two words?S3:“Aim”should be about what the experiment is for. For“conclusion”, I have no idea.T: Right.“Aim”means purpose or object. For example, he has only one aimin life, that is, to be a millionaire. And for“conclusion”, lets see anexample first, when you have worked on a maths problem for a long time,but you still cant workit out. So you may make a conclusion that the problem is wrong. Here,“theprobl em is wrong”is your conclusion. Do you understand?Ss: Yeah!T: Now who can give us some other examples to show the meaning of“aim”?S4: Many people aim to be a millionaire. But I think to serve people is thehighest aim.T: What is the correct order of stages to do an experiment?Ss: It should be aim, method, result and conclusion.T: That s right. Without aim, we don t know where to go; without method,we don t know how to do things well; without result, we ll draw a blankor gain nothing;without conclusion, we ll find what we ve done is worthnothing.Task 2: Activity 2Ask the students to scan Passage A and find the best title for the passage.T: Please look at Activity 2. What you should do is to scan Passage A anddecide which is the best title for the passage.Give the students some time to do the job and then check the answer.T: Well, what s the best title for the passage?S4: The Reaction of Metals.T: Why?S4: The writer begins the passage by introducing the different uses ofdifferent metals. But for the rest part of the passage, including the table,he / she mainly describes several metalsreaction with differentsubstances.T: What a good reason it is! Now, let s look at Activity 3.Task 3: Activity 3Ask the students to read and answer the questions below the passage. Givethem some time to do the job. After that, check the answers with the wholeclass.Step IV Reading (Passage B: P45)In this part, the students will read the passage and then fill in the table belowthe passage.There are three Tasks in this part. The first one is to ask the students to findthe structure of the passage and finish the table. The second one is to dealwithActivity 5. The third one is to finish Activity 6.Task 1: Structure of the passageT: Now, we ll continue to read Passage B. The title of it is A SimpleScientificExperiment. From the passage we can see how the experiment is done.What is the structure of a description of experiment? Who can come to theblackboard to write down the structure?S: Let me try.A student comes to the blackboard and writes down the structure.A Simple Scientific Experiment:IntroductionAim Apparatus Method ResultConclusionT: OK. Weshould notice that there are 3 different reactions which arerespectively described with method, result and conclusion. Now, pleaseread the passage and then fill in the table.Let the students do the job, and then check the answers with the wholeclass.T: Well, what is ordinary water according to the experiment?S6: I think ordinary water here means the water that has not beenboiled, and has air in it.T: Right. Wealso call ordinary water “raw water ”. Nowwhat s “ Bunsenburner ” Weoften find it in labs. Now, turn to page 46, and find the pictureof Bunsen burner. Task 2: Activity 5T: Now please turn to page 46. Look at Activity 5. Read Passage B again.Complete the sentences.After the students finish the sentences, ask some of them to read out thecomplete sentences and check the answers with the whole class.Task 3: Activity 6This part is about vocabulary study. Let the students read after the teacher,and then work in pairs to find the meanings of the new words.Explanations of some words:React: have effect on (of one substance applied to another)Steam: gas from boiling waterOil: liquid which does not mix with water, obtained from animals, plantsor foundin rock under-groundBoil: (of water or other liquid) reach the temperature at which change togas occurs Scientific: of, for, connected with, used in scienceExperiment: test carried out carefully in order to study what happensand gain new knowledgeFloat: be held up in air, gas or on the surface of liquid; move with liquidor airForm: give shape or form to; make, produceDissolve: (of a liquid) soak into a solid so that the solid itself becomesliquidStepVLanguage PointsAsk the students to translate the following sentences, and get familiar withthe sentence structures.Show the following sentences on the screen.1. It is hard to think of a world without metals.2. It is important to know how they react with different substances, forexample, waterand oxygen.3. This makes sure there is no air in the water.T: Before we finish this class, lets look at the screen. There areon it.Can you translate them into Chinese?Let the students translate the sentences into Chinese.T: OK. In fact, these sentences involve two sentence structures.One is: it is + adj. + to do something. The other is an objectclause. Now letsentences to get familiar with the two sentence structures.threesentens look at moremore sentencesWrite down the structures on the blackboard and then show the students onthe screen:1. Its hard (difficult) to say which is better.2. Its foolish (silly) to act like that.3. Its easy to learn a foreign language.4. Its impossible to finish the job in one day.5. Its wrong to steal.6. I only came to make sure that everything was all right.7. Father makes sure that all the lights are off before he goes to bed.8. Make certain that your facts are right.9. We must make certain that she can come.Let the students translate the sentences. If they have any difficulty, givethem some help.StepWHomeworkT: Today, we have learned some new words and two passages aboutscientific experiment. After class, please do Exercises 6, 7 and 8 on pages92&93. These exercises can help us remember the new words andexpressions about scientific experiment. OK, that s all for today. See younext time.Ss: See you.The Second Period Listening and SpeakingTeaching goals 教学目标1. Target language 目标语言English numbers2. Ability goals 能力目标Help the students to read and write some English numbers correctly.Help the students find the main parts of an experiment while they arelistening.3. Learning ability goals学能目标Help the students know the rules of expressing numbers.Help the students guess the main parts of a listening material from the tips.Teaching important points 教学重点Let the students pay attention to the key words in the materials about Aim,Equipment, Method, Result, and Conclusion.Teaching difficult points教学难点Help the students read some large English numbers.Teaching methods 教学方法Listening and discussion.Teaching aids 教具准备A projector and a recorder.Teaching procedures & ways 教学过程与方式StepIRevisi onCheck the students homework. For Exercises 6 and 7, give them answersheet. ForExercise 8, ask 10 students to read out the complete sentences one by one.They should pay attention to their pronunciation and intonation.StepnListening and WritingThis is a continued part to the reading material. The students can get morefamiliar with some new words and expressions, and also get familiar withthe description of an experiment. Ask the students to scan the threeactivities in LISTENING ANDWRITING on P46, so that they know what theyare going to do, and try to get ready to catch the key words or key sentenceswhen they are listening.T: Now, please turn to page 46. We are going to have a listening. At first,scanthe three instructions to know what you are going to do.Several minutes later.T: Do you know what you are going to do?Ss: Yes.T: Whats the first one?S1: To read the Aim below and predict the Result.T: What is your prediction?S1: I think there are two results. Oneis that the magnesiumis heavierthan before.The other is that it becomes a little lighter than before. Its difficult to geta result, unless we make an experiment.T: Good, this is a correct attitude towards science. Now, well listen to theconversation to find the result. So please listen carefullyand write down the keywords.Play the recorder for the students to have a first listening. After that, let thestudents write down their answers using the key words. If possible, askthem to write the whole sentences.T: Now lets listen and complete the description of the scientific experiment.Weve known the Aim and Result. What we should focus on is Apparatus,Method and Conclusion. And for Method, we should pay attention to thefunction words: first, then, next, after that, and lastly. Do you remember?Ss: Yes.T: OK, lets listen again.Play the tape recorder again. The students listen to the recorder andcomplete their sentences. At last, collect the answers.Step 川 Listening and Speaking (P95)This is another experiment for the students to have a listening. The purposeof the listening is the same as the above one. Ask the students to read theexercises before listening, including Exercises 13, 14 and 15, so that theyknow clearly what they are going to do.T: Now, we ll have another listening. Are you clear about what you aregoing to do?Ss: Yes.T: OK, for Exercise 13, we have to decide what the aim of the experiment is.And then decide the correct order of the stages. So, first look at the pictures,work in pairs to describe what the boy is doing.Let the students do the job, and then collect their descriptions.T: Well, just now, I collected some of your descriptions about what the boy isdoing.Look at the sentences on the screen.Write the following sentences on the screen.a) Bob is writing a conclusion.b) He is squeezing a lemon.c) He is going to fire the paper.d) This is the aim of the experiment.e) He just lighted a candle.f)He is going to write something on the paper.g) He is blowing the paper.T: All of these descriptions are very good. Now let s listen tothe tape to findthe aim and put the stages in the correct order.After the students finish the task, check their answers with the whole classby listening to the material again.T: Well, it s time fo
