高一英语必修3Unit 4Astronomy the science of the stars知识点总结
Unit 4 Astronomy：the science of the starsPeriod 1 Grammar points.一．语法要点主语从句：在复合句中作主句的主语的从句叫主语从句。
引导主语从句的词有连词that, whether；连接代词who, what, which；连接副词when, where, how, why等。
Eg: Which team will win the match is still unknown.主语从句放在句首，句子常显得笨重，因此一般把它放到句子后面，前面用引导词”it”来作主语。
Eg: It’s strange that he didn’t come yesterday.二．重点难点1．Nobody knew that it was going to be different from other planets going to be different from other planets going round the sun.going round the sun 为现在分词短语定语，表示一般的动作。
Eg: Men breaking the law will be punished.现在分词短语，也可表示进行的动作2. Weather life will continue on the earth for millions of years to come will depend on whether this problem can be solved.for millions of years to come 中不定式to come 作定语，与前面的名词有逻辑上的主谓关系。
Eg: She is the last person to tell lies.3．The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.The problem was that …, that 引导表语从句，that 只起连接作用，无意义，但不能省略。

Unit 4 Astronomy: the science of the starsWritingTeaching goals1 Target languagea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 goalsEnable the Ss to write an article about your idea or hopes for traveling in space.3 Learning ability goalsHelp the Ss to learn how to write a passage.Teaching important& difficult pointsTeach the Ss how to write an article about a space travel.Teaching methodsTask-based learningDiscussion.Teaching aidsa projector, a computerTeaching proceduresStep 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? Wehave 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 don’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 valuable 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 been recently discovered and given provisional designators until they are officially confirmed and named.InformationFindings 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 V oyager 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..。
