2019-2020学年高中英语人教版必修三Unit 4 Astronomy: the science of the starsTeaching goals 教学目标1 Target language目标语言a重点词汇和短语explore, characteristicsb重点句子Write a short article explaining three problems you might meet on the moon..You may ask the following questions as well as work out some more.2 Ability goals 能力目标Enable the Ss to write an article about your idea or hopes for traveling in space.3 Learning ability goals 学能目标Help the Ss to learn how to write a passage.Teaching important& difficult points教学重点和教学难点Teach the Ss how to write an article about a space travel.Teaching methods教学方法Task-based learningDiscussion.Teaching aids教具准备a projector, a computerTeaching procedures & ways教学过程与方式Step I WritingThe purpose of this writing is for students to think about what kind of equipment they would need to be safe in space. It’s a good opportunity for a discussion about the pains and pleasures that might occur when traveling in space. After the discussion, they can write down the problems and the way to solve them.T: If you are going off on a holiday, what will you take?S1: I will take clothes, shoes, food and many other things.T: But for space travel, you need specialized equipment. What equipment should you take? We have discussed them in last lesson. Who can answer this question?S2: oxygen can, spacesuit, gravity boots, water system, special food., special ropes, space buggy, sunglasses and space camera.T: We take so many things with us in order to avoid many dangers. What are the dangers? If you do n’t know many enough, let’s watch the film “Apollo”. It’s a film about an American space mission that went wrong. After that, you should write down the dangers and the way to solve them.(Watch the film.)Sample article:If I visited the moon, I might have three problems: how to breathe, how to eat and how to move around.I would have to carry all my air with me if I went to the moon. This is because the moon has no air of its own. So I would need oxygen tanks placed on my back so I could breathe all the time.I would have to take all my food with me if I went to the moon. In the spaceship, there is no gravity so the food would float around. So, I would make sure that it is specially made as space food and then I would be able to eat it easily.I would find it difficult to move around on the moon as I would weigh one-sixth what I weigh on the earth. This means I would bounce like a balloon if I try to walk. I would have to learn to walk differently so that I don’t fall over.If I follow this advice, I think I will have a good holiday on the moon.Step II Writing TaskThe purpose of this writing task is for the students to use the information they have gathered on astronomy and their questions to each other to write an interesting and lively newspaper article. T: Have you ever remembered Oct.16th, 2003?S: Yes, of course..T: What happened on that day?S: China’s first manned spaceship landed safely that day.T: It’s a great moment for China and the whole world. How many preparations have they made for this space travel?S: Not exactly. But they must have made full preparations for this manned space flight.T: Do you admire Yang Liwei?S: He is our hero.T: Do you want to be a great man like him?S: Of course, I’m dreaming of that.T: You’ll get the chance if you work hard.. China has other new plans. The scientists plan to put a lab into space manned by scientists for short periods. They aim to visit the moon to look for valuable resources there as well as to study its environment and geological structures. Do you want to be that lucky scientist? Suppose you are the scientist who visits the moon in the future, please tell us your plan. For example, you can think about these questions and write down your plan.1.What preparations should you make?2.What will you see during your space travel?3.What will you do on the moon?Show sample article:Going into spaceCarry out research on the moonI’ll visit moon soon. As a scientist, I have always wanted to visit it by myself. But it’s not an easy thing. So I should make many preparations. First I’ll take enough exercise in order to be strong. Then I’ll take enough and necessary equipment with me. I will make notes of what I’ll see on the moon because we’ll put a lab on it. Through experiments in the lab, we’ll collect va luable resources and study its environment and geological structures.We’ll also want to find out if it’s a good place for humans to live in in the future. I believe I’ll get what I want to get from the moon. (Teacher can supply other information for students. Show the following on the screen:)China’s manned space programme has four goals:1.to develop basic manned space flight technology;2. to observe the earth and undertake experiments in space;3. to help design space vehicles;4. to accumulate experience for a large space stationT: Suppose you are part of this future programme, talk about what you’ll do, what you’ll see and what you’ll get.Step III ProjectAsk students to collect as much information as they can about the nine planets in our solar system. Choose one planet that they would like to explore. Then write a research report. The report should include the four requirements on Page68.1.One possible project:Topic: MarsThe planet I have chosen is Mars because it’s the closest to the earth and it’ll be one of the first planets for us to explore. It’s named after the Roman god of war because from the earth it looks red in the sky.InformationPosition: 4th planet in our solar systemDistance from our sun: 228 million kmsDiameter: half the size of the EarthMass: one tenth the size of EarthGravity: one third of that of EarthSurface size: same as dry land of EarthLength of day: half an hour longer than Earth dayTime to circle the sun: two Earth yearsSatellites: twoAir: 95% carbon dioxide 2% argon, 3% nitrogen, very little oxygenFindings from space tripsThe most important trips to Mars have been made by the US and USSR. They have both sent many spaceships but no people to visit Mars. They have discovered:---there are two seasons on Mars: a warm, dusty, southern summer and cold, dusty-free northern winter.---no life can live on Mars now, as the air doesn’t have enough oxygen---there are some evidence of early life when there was water on Mars three million years ago---changes in the color of Mars are produced by dust storms on Mars---it has a north and a south pole made of frozen carbon dioxide gasWhat I would like to find out1.whether there is life under the surface of Mars2.whether it would be possible for people to live on Mars3.whether there is oil or jewels or rocks that would be useful for people on Earth2.Another project:Topic: JupiterJupiter is the fifth planet from the Sun and is the largest one in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains more matter than all of the other planets combined. It has a mass of 1.9 x 1027 kg and is 142,800 kilometers (88,736 miles) across the equator. Jupiter possesses 28 known satellites, four of which - Callisto, Europa, Ganymede and Io - were observed by Galileo as long ago as 1610. Another 12 satellites have beenrecently discovered and given provisional designators until they are officially confirmed and named.InformationJupiter StatisticsMass (kg) 1.900e+27Mass (Earth = 1) 3.1794e+02Equatorial radius (km) 71,492Equatorial radius (Earth = 1) 1.1209e+01Mean density (gm/cm^3) 1.33Mean distance from the Sun (km) 778,330,000Mean distance from the Sun (Earth = 1) 5.2028Rotational period (days) 0.41354Orbital period (days) 4332.71Mean orbital velocity (km/sec) 13.07Orbital eccentricity 0.0483Tilt of axis (degrees) 3.13Orbital inclination (degrees) 1.308Equatorial surface gravity (m/sec^2) 22.88Equatorial escape velocity (km/sec) 59.56Visual geometric albedo 0.52Magnitude (Vo) -2.70Mean cloud temperature -121°CAtmospheric pressure (bars) 0.7Atmospheric compositionHydrogen Helium 90% 10%Findings from space trips1.There is a ring system, but it is very faint and is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.)2.The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds.3. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.4. Colorful latitudinal bands, atmospheric clouds and storms illustrate Jupiter's dynamic weather systems. The cloud patterns change within hours or days. The Great Red Spot is a complex storm moving in a counter-clockwise direction.5. Auroral emissions, similar to Earth's northern lights, were observed in the polar regions of Jupiter.What I would like to find out1.whether there is life under the surface of Jupiter2.whether it would be possible for people to live on Jupiter3.whether there is oil or jewels or rocks that would be useful for people on EarthStep V HomeworkSum up the whole unit.Collect the materials about stars, space travel and different ideas about the beginning of life..。

3.His analysis is too _________.
4.If there was no _________, no one would enter the classroom after the break.
5.All of them follow the _________ of the example presented.
All these signs of water are very exciting. Why? Because on Earth, almost everywhere there is water, there is life. Whether the water is boiling hot or frozen, some sort of creature seems to thrive in it. Is it the same on other planets? If water once flowed on Mars, did life once thrive there too? Or, maybe there is still water on Mars, only it has gone underground. Could there be tiny life forms—like bacteria—on Mars even now?
2019-2020年人教版高中英语必修三教学案：Unit 4 Section 1(含答案)
If you watch the sky about an hour after the sun goes down, youmay see some “moving stars”. But they're not real stars. Theyare man-made satellites. And the biggest of all is the InternationalSpace Station (ISS国际空间站)．From now until July is the best season to watch the ISS flying overthe earth, and people can see it just with their eyes. The ISS is thebiggest man-made satellite because scientists want to live on it. Theythink that the best way to learn more about space is to live there.When the space station is finished, it will be like a city in space.People will stay and study there with many of the things they haveat home. Laboratories, living rooms and power stations are being built.The ISS is the most ambitious and expensive space programever. Billions of dollars are being spent on it every year. Scientistshope that the ISS will be a stepping-stone for future space exploration.“The ISS will help us better understand the human body, explore spaceand study the earth. It can help us make life on the earth better，”said Kathryn Clark, an ISS scientist.China is not an ISS country, but it has helped with some of the experiments. China sent some rice up to the ISS to find out whatspace would do to it.The ISS is not finished yet. More than 100 parts need to be put on.Scientists hope it will be finished as soon as possible. After it'sfinished, more than 90% of the world's population will be able to seethe Space Station. So keep looking up, and maybe you'll see it get bigger.2019-2020年人教版高中英语必修三教学案：Unit 4 Section 1(含答案)[原文呈现][读文清障]HOW LIFE BEGAN ON THE EARTHNo one knows exactly how the earth began, as it happened so long ago①.

There are still many things to discover in the ocean depths and the Antarctic.But we do not even have to go that far:Science has yet to unlock all the mysteries of the atom,and there are many realms of technology that we are justbeginning to understand and explore.In the end,it just does not seem a very wise investment to go to space.We have too many needs here on the earth to be wasting our effort on space exploration.StepⅠ Homework假定你是李华,你班最近一次班会的主题是“太空探险的意义”。
