Unit 4 Astronomy: The Science of The StarsTeaching aims:1.Enable students to improve their listening skills and reading ability.2.Enable students to understand the development of gravity and how gravityaffects us in different times and places.3.Arouse students ’ interest to search for the mystery of space.Emphasis:1.Words and expressions: gravity, float, cheer up, now that, break out, etc2.Astronomic knowledge like gravity and black hole.Difficulties:1.Help the students to understand the development of gravity.2.Help the students to know how gravity influences us.Teaching methods:skimming, scanning, discussing.Teaching aids: tape recorder, a projector and a computer.Teaching procedures:Period one ReadingStep 1. PresentationT:Hello, everyone!odayT we ’ ll come to Unit 4 Astronomy. Before that I have a question: Where do we come from? Or we can say: Who are our ancestors?S1: Monkeys!S2: Beijing Ren who lived many years ago.S3: Reptiles.S4: Mammals.S5: Amphibians.S6: Dinosaurs.T: Very good! Can you put them in right order?S7: Amphibians, Reptiles, Dinosaurs, Mammals, Beijing Ren.T:Do you know what it was like before life appeared on earth?S8: It was full of water, perhaps.T: Before that, what was it like?S9: Sorry, I don’ t know.T: Do you want to get more information? Today we’ ll learn something about How Life Began the Earth. Turn to Page 25. Let’ s come to Warming up first.Step 2. Warming up1.Read the three questions, while the students listen and follow.2.Give the Ss several minutes to discuss the questions.3.Collect answers from the whole class.4.Check the answers while discussing.T:I ’ ll read the three questions for you. You should listen to me carefully. (If students don howto discuss, show them an example.) For example, medicine. When someone gets seriousillness, he will go to the hospital. The doctor will examine him. He will take his temperature, measurehis blood pressureand give him an X-ray, or a CT. For the whole process of the examination, what kind of science has been used?S1: Biology.S2: Chemistry.T:So we can say medicinecombinesbiologyand chemistry.What aboutbiochemistryand geophysics?S3: I think biochemistry combines biology and chemistry.S4: Geophysics combines geology and physics.T:What about astronomy?S5: Physics.S6: Mathematics.T:Very good. We should know that astronomy is a multidisciplinary subject and if we want todo some researchon it, we shouldknow many sciencesubjectsrelatedto it. Now discussthesecond question:Whatdo we mean when we say we are studying a subject scientifically? Or what’ s t attitude towards science?S7: We should be objective, not superstitious.T: What ’ s the correct way to prove a scientific idea?S8: We should design experiments to test it for several times.S9: Then we can analyze the results and draw a conclusion at last.T:Let ’ s sum up the answers. To study a subject scientifically, we must try to be objective. Inorder to test our idea, we shoulddesign experiments,then analyzethe results and draw a conclusion. Now let’ s talk about the third question.What are the most important skills we need to be real scientists?S10: We should be very careful.S11: Be objective and logical.S12: We should be wise enough to design an experiment and write the reports clearly.S13: We should be able to draw conclusions from the experiments and not imposeconclusions on the data.T: I think you have done great work. From the discussion we know that it’ s not e scientist. So you should work harder if you want to be a scientist.Step 3. Pre-readingGet the Ss to discuss the questions on Page 25 with their partners. Then ask the Ss to tell their stories. Encourage the Ss to tell different stories. If they don’ t know any, tell th T:Nowplease look at the slide show. And discuss these questions with your partners. ThenI ask some students to tell us their stories. Are you clear?Ss: Yes, Sir/Madam.1. Do you know each religion or culture has its own ideas about the beginning of the universe? Please give an example if you know.2. Do you know what a scientific idea is?After the Ss ’ discussion, teacher says the following.T:Now who ’ d like to tell us a story? Volunteer!S1: Let me try. In China, we all know that Pangu separates the sky from the earth.T:Can you describe the story in details?S1: Sorry, I can’ t remember clearly.T:Who can? Nobody? Now I ’ ll tell you. Look at the screen.Step 4. ReadingScanningGet the Ss to read the passage quickly and accurately and meanwhile helpSs thetoform agood habit of reading.Teachergives the Ss a coupleof minutesto look throughthe wholepassage. Tell the Ss to read the text silently and then ask some detailed questions aboutthe text on the slide show with their partners. Teacher shouldencourage the Ss to expresstheir ideas.T: We ’ re going to learn a passage about how life began on the earth. Now let ’ s show. Read the text quickly and find answers to the following questions. Show the questions on the screen.1.What was there on the earth before life could begin?2.Why do scientists think there has never been life on the moon?3.Why did animals first appear in the seas?4.Why did green plants help life to develop?5.Why were mammals different from other animals?T: Now who can answer the first one?S1: Water vapour, carbon dioxide, oxygen, nitrogen and other gases.T: What about the second one?S2: Because there is no water on the moon.T: What about the third one?S3: Because water allowed the earth to dissolve harmful gases into the oceans and seas.T: The fourth one?S4: Becausegreenplants can takecarbondioxidefrom the atmosphereand fill the airwith oxygen.T: What about the last one?S5: They were different because they produced their young from within their bodies.T: Well done! Now turn to Page 26 Comprehending1, I think you may continue to read it againto get more details.SkimmingIn this part, Ss will read the text again and then finish Part1, 2 and 3.T:Now please skim the passage fast to finish Part1. Then we will check the answer.Key to Part1: BCBBT:Skim Paragraph 2, 3 and 4, and finish Part 2 and 3.Key: DBIGEHACFJT:For Part 3, discuss them with your partner.T:Why is it wrong in films and stories to show dinosaurs and people together?S:Because dinosaurs died out long before human beings developed on the earth.T:Do you agree with him?S:Yes.T:What about the answer to the second question?S:They are the cleverest animals because they have larger brains than any other creatures on the earth so far.T:Excellent job! I ’ ll check how much you have learned about the passage. Step 5. ListeningListen to the tape for the students to follow and have further understanding of the passage. T:Read after the tape, then answer me some questions with your book closed.Play the tapeT:How did water come into being on the earth?If one student can’ t answer completely, ask two or three or more students.Ss: The explosion of the earth produced water vapor, which turned into water when the earth cooled down.T:Why is water important on the earth?Ss: Because water allowed the earth to dissolve harmful gases into the oceans and seas. T:No.3, finish the following form.1 small plants in2water3 green plants on land4insects(on land)576 forests89Key to the exercise:2.shellfish and all sorts of fish5.amphibian(on land and in water)7.reptiles (on land) 8.dinosaurs(on land) 9.mammals(on land)T: That’ s all for this passage. Now let’ s deal with some language points. ExplanationT: Turn to Page 25. Let’ s look at the sentences:1.It exploded loudly with fire and rock, which were in time to produce the water vapour. which leads non-restrictive attributive clause.in time: sooner or later;eventually I ’ ll see him in time.in time (for sth. /to do sth.): not lateShe will be back in time to prepare dinner.in / out of time: in/not in the correct time Theaudience clapped in time to the music.2.Nobody knew that it was going to be different from other planets going around the sun. be different from: not like someone or something else in one or more waysNote: We can use very, much, quite, entirely, totally to modifydifferent City life is quite different from country life.going around the sun is-ing form that serves as attributive.Men breaking the law will be punished.Can you see the girl dancing with your boyfriend?3.Whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.to come: serves as attributiveShe is the last person to do such a thing.depend on: something might only happen or be true if the circumstances are right for it Our success depends on whether everyone works hard or not.4.

Discussion and cooperative learningTeaching aids教具准备1 A computer2 A projectorTeaching procedures & ways教学过程与方式Step I RevisionAsk some of the Ss to read his / her passage about gravity.One possible passage:Sir Isaac Newton: The Universal Law of GravitationThere is a popular story that Newton was sitting under an appletree, an apple fell on his head, and he suddenly thought of theUniversal Law of Gravitation. As in all such legends, this isalmost certainly not true in its details, but the story containselements of what actually happened.What Really Happened with theApple?Probably the more correct version of the story is that Newton,upon observing an apple fall from a tree, began to think alongthe following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "accleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree.Sir Isaac's Most Excellent IdeaNow came Newton's truly brilliant insight: if the force of gravity reaches to the top of the highest tree, might it not reach even further; in particular, might it not reach all the way to the orbit of the Moon! Then, the orbit of the Moon about the Earth could be a consequence of the gravitational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.This can be illustrated with the thought experiment shown in the following figure. Suppose we fire a cannon horizontally from a high mountain; the projectile will eventually fall to earth, as indicated by the shortest trajectory in the figure, because of the gravitational force directed toward the center of the Earth and the associated acceleration. (Remember that an acceleration is a change in velocity and that velocity is a vector, so it has both a magnitude and a direction. Thus, an acceleration occurs if either or both the magnitude and the direction of the velocity change.)But as we increase the muzzle velocity for our imaginary cannon, the projectile will travel further and further before returning to earth. Finally, Newton reasoned that if the cannon projected the cannon ball with exactly the right velocity, the projectile would travel completely around the Earth, always falling in the gravitational field but never reaching the Earth, which is curving away at the same rate that the projectile falls. That is, the cannon ball would have been put into orbit around the Earth. Newton concluded that the orbit of the Moon was of exactly the same nature: the Moon continuously "fell" in its path around the Earth because of the acceleration due to gravity, thus producing its orbit.By such reasoning, Newton came to the conclusion that any two objects in the Universe exert gravitational attraction on each other, with the force having a universal form:The constant of proportionality G is known as the universal gravitational constant. It is termed a "universal constant" because it is thought to be the same at all places and all times, and thus universally characterizes the intrinsic strength of the gravitational force.Step II PresentationT: Do you remember the conversation between Li Yanping and Professor Wallis?S1: Yes.T: We all know that space walk is difficult and dangerous. What should an astronaut take with him? S2: oxygen can.S3: spacesuit.S4: gravity boots.S5: water system.S6: special food.S7: special ropes.T: Great! Do you know the usage of them? Now discuss them with your partner according to the form on Page31. You can refer to our listening material on Page65.When Ss discuss. Teacher walk around the classroom to give them some help.Step III Speaking (Page31)(After a few minutes.)T: Have you finished? Now speak one or two sentences for each equipment you should take.Sa: I will take water with me in my spacesuit in order to warm or cool me if it’s too cold or too hot. Sb: I will take oxygen can on my back in order to help me breathe oxygen in space.Sc: I’ll wear spacesuit. t can protect me from many dangers. It can carry many necessary things in or on it.Sd: I’ll take space buggy in order to travel on the moon.Se: I’ll take a rope to tie me to the spaceship, or I’ll fly away.Sf: I’ll take special food so that I can eat easily, because the food will float in space.Sg: I’ll wear special sunglasses in order to protect my eyes.Sh:I’ll take space camera in order to take photos.T: Wonderful! Anything else?Si: I’ll wear space boots in order to walk there.T: Very good. You’ve done an excellent job! Do you know how to fill in the form now?Ss: Yes.T: Now look at the screen and check your answer.Sample answer:Step IV Talking (Page62)The task asks the students to work in pairs and give a friend a number of “does” and “don’ts” for going into space. They need to make suggestions using the phrases that they have been given to help them. When they have worked out the advice they can write the suggestions down and read them out to the class.Show the useful expressionsPlease look at/ listen to…Please check that…You need…Please pay attention to…Don’t forget to…You’d better…Make sure you…Watch out for…You mustn’t…T: Now discuss it in pairs. Then I will ask some pairs to read out their instructions.Sample dialogue:S1: I’m going to visit a comet. I’m leaving tomorrow.S2: How exciting! Please check that you have got the correct sort of spacesuit. You need the kind that will keep you warm if it’s too cold.S1: Of course!S2: Make sure you know all the safety rules. It’s not safe to stand on a comet or get too close.There is always a strong wind in space.S1: I won’t leave the spaceship except that I take photos.S2: Photos? Just think of the dust in the air. It will make taking photos very difficult.S1: Well, I’ll take some anyway.S2: Watch out for the space wind! It can be very dangerous.S1: Yes, I know that.S2: Don’t forget to watch the time as you leave the earth. Please pay attention to everything your space guide says. Don’t go off on your own. Look at your temperature on your spacesuit all the time. If it’s too low you need to warm it up and if it’s too high you need to cool it down. Anyway, have a good trip!S1: Thank you. I will.Step V Speaking Task (Page67)The purpose of this task is to use the information the students have gained from the listening text and reading passage in a new situation. They are going to interview the astronomer in our story, Li Yanping, for a newspaper. So in pairs the need to work out some questions to ask him. Each of the pairs needs to think of three different questions. And try to find the answers.Questions and answers:1.What was the most unexpected thing you found out about black holes?The black hole threw out material as well as ate objects.2.How did you know you had got close to a black hole?You can see things disappear into what appears to be an empty space. That’s a black hole.3.What was the most frightening thing that happened to you on this journey?When the gravity of the black hole was pulling us to it’s mouth, and then the spaceship moved round the hole and began to go faster and faster into it; I was terrified because I thought we would be eaten by the hole.4.Why did your watch move slower when your spaceship moved around the hole?I’m not clear yet.5.Have you found something new about black holes?Yes. I thought black holes only eat some objects, but in fact they also spit objects out.Step VI Homework:Prepare for writing a passage about your idea or hopes for traveling in space.。

Unit 4 Astronomy: the science of the starsHOW LIFE BEGAN ON THE EARTHNo one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a “Big Bang ”that threw matter in all directions.After that, atoms began to form and combine to create stars and other bodies.For several billion years after the “Big Bang ”, the earth was still just a cloud of dust. What it wasto become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon dioxide, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.Water had also appeared on other planets like Mars but, unlike the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas. This produced a chain reaction, which made it possible for life to develop.Many millions of years later, the first extremely small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They produced young generally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than140 million years. However, 65 million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth. These animals were different from all life forms in the past, because they gave birth to young baby animals and produced milk to feed them.Finally about 2.6 million years ago some small clever animals, now with hands and feet, appeared and spread all over the earth. Thus they have, in their turn, become the most important animals on the planet. But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space. As a result of this, many scientists believe the earth may become too hot to live on. So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.A VISIT TO THE MOONLast month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!Before we left, Li Yanping explained to me that the force of gravity would change three timeson our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull ofthe earth ’s gravity. It was so hard that we could not say anything to each other. Graduallythe weight lessened and I was able to talk to him. “Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground. ”I asked. “We are too far from theearth now to feel its pull, ”he explained, “so we feel as if no gravity at all. When we get closer tothe moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth’s.”I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.When we got there, I wanted to explore immediately. “Come on, ”I said. “If you are right, my weight will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!”I laughed and climbed down the steps from the spaceship. But when I tried to step forward. I found I was carried twice as far as on the earth and fell over. “Oh dear,”I cried, “walking does need a bit of practice now that gravity has changed. ”After a while I got the hang of it and we began to enjoy ourselves.Leaving the moon ’s gravity was not as painful as leaving the earth ’s. But returning to the earth was very frightening. We watched, amazed as fire broke out on the outside of the spaceship as the earth’s gravity increased. Again we were pushed hard into our seats as we came back to land. “That was very exhausting but very exciting too,”I said.“Now I know much more about gravity!Do you think we could visit some stars next time? ”“Of course,”he smiled, “which star would you like to go to? ”。
