Reading and ThinkingSPACE: THE FINAL FRONTIER太空：最后的边境“Are we alone? What’s out there?” Looking up at the stars, people have always wanted to learn more about space, and scientists work hard to find answers. They make“我们是否孤独？太空以外是什么？”仰望星空，人们一直想更多地了解太空，科学家们也在努力寻找答案。
他们制造运载勇敢的人儿进入太空的交通工Before the mid-20th century, most people felt travelling into space was an impossible dream. However, some scientists were determined to help humans realisewas lunched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, “That’s one small step for [a] man, one giant leap for mankind.” Following this, many more goals were achieved. For example, America’s NASA space agency launched Voyager 1 on 5 September 1977 to study deep space, and it still transmits data today.在20世纪中叶之前，大多数人都认为进入太空是不可能实现的梦想。

On the station, the ordinary becomes strange.The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity，it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long.Without gravity to help circulate air, the carbon dioxide you exhale(呼气)has a tendency to form an invisible(隐形的) cloud around your head.You can end up with what astronauts call a carbon-dioxide headache.

人教英语必修3 Unit 4 Astronomy the science of the stars Listening exercise 听力原文(文本素材)
Using LanguageTHEORIES OF GRAVITYMichael Jones of the New Space Magazine is talking with space traveller Li Yanping about changes in the theory of gravity.LY = Dr Li YanpingMJ = Michael JonesListen to Part 1.Listen again and fill in the blanks.MJ: Hello, Dr Li Yanping. It’s so good of you to talk to me. Some students ask us why things always fall back to earth if you throw them up in the air. Could you explain it? LY: Well, at first people thought it was because the earth was the centre of the universe. Of course that was wrong. One day Isaac Newton watched an apple fall to the ground. He said that something else must be pulling the apple back to earth. He called it “gravity”.MJ: I see. Did people accept his idea?LY: They did. Later they worked out that bigger objects (like the sun) have stronger gravity than smaller objects (like our planets). If you’re travelling in deep space, you couldn't fall back to the earth. You’re just too far away.Listen to Part 2.Listen again and fill in the blanks.M J: Does it mean there’s no gravity in space?LY: No. In a spaceship you would feel the pull as it got closer to such an object. You would travel faster and faster towards it.MJ: Until you hit it?LY: Not exactly. You may pass it very fast and then it would throw you out into space again. After that you would slow down to the usual speed.MJ: How do you know this?LY: In 1905 Einstein said that in space large objects make space-time bend; the larger the object, the further space-time bends. So time goes slower in very strong gravity. MJ: What about black holes?LY: That’s a place in space which has such a strong mass that nothing can escape from its gravity. There is a kind of edge around this mass. If you cross over this edge, it’s impossible for you to get back. However if you don’t cross this edge, you can still escape. Stephen Hawking has done a lot of research into black holes. He has shown that they “spit” things out as well as “eat” them.Workbook-ListeningAN INTERVIEW WITH YANG LIWEIR = Mr Renault Y = Yang LiweiListen to Part 1.Listen again and fill in the blanks.R: Thank you so much, Mr Yang, for coming to talk to us today about your experience in space.Y: Not at all. I’m happy to be here.R: Please can you tell us your most exciting moment?Y: Well, that was when the spaceship began to lift off the ground. Then I knew that I was really on my way and that China would become the third country to send people into space.R: Did you feel afraid?Y: No, because I was trained not to worry. So I watched all my instruments and stayed calm.R: What surprised you?Y: The beauty of space. I’d never realized how lovely the earth looks till I was going round it.Listen to Part 2.Listen again and fill in the blanks.R: Did you always want to be an astronaut?Y: Well, I dreamed of it when I was young, but I never thought my wish would come true. It all happened gradually. First I got my degree and then I trained for ten years to fly airplanes and then to fly a spaceship.R: I see. Did you have to be a certain size and weight?Y: Yes. An astronaut has to be smaller than 170 cm and weigh less than 70 kg.R: So you were the perfect choice! But of course you had to work very hard. Would you like to go into space again?Y: Yes, I would if there was an opportunity. I’d love to go to the moon one day.R: I hope we’ll be talking to you again after you’ve finished that trip! Goodbye, Mr Yang. Thank you for talking to us.Y: It was my pleasure.Workbook-Listening TaskAN INTERVIEW WITH LI YANPINGW = Wallis L = Li YanpingListen again and fill in the blanks.W: Mr Li, would you please tell us about your space walk?L: Yes. I’d be happy to. We cleaned and repaired the Hubble telescope.W: Oh, and is that when you did your space walk?L: Yes.W: How did you prepare for it?L: First we had to get into spacesuits. They’re very thick and carry all the oxygen we need to breathe. The suit also has hot and cold water so it can warm us if it’s too cold or cool us if it’s too hot. So it’s very heavy.W: Is it dangerous to leave the spaceship?L: Yes, indeed. When we leave, we go into a small room. We have to wear gravity boots to walk there. We close the door behind us and then we open the door to space. Then our gravity boots stop working and we fly out of the door.W: How do you move about in space?L: We use small engines to move around. To go left we push the right engine and to go right we push the left one. We move slowly because we don’t weigh anything. We can fly around like feathers.W: What does it feel like in space?L: Very strange. There is no gravity so doing any job is very tiring.W: What happens if you fly too far from the spaceship?L: You’d never get back so we tie ourselves to the spaceship with a special rope.W: How did you repair the Hubble telescope?L: We used some special tools tied round our waists. That way we didn’t lose them. We did a good job. The telescope works fine now.W: Thank you very much, Mr Li.。

HOW LIFE BEGAN ON THE EARTH地球上生命的起源No 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.没有人确切知道地球是怎么样开始形成的，因为在很早很在以前地球就形成了。
然而，一种普遍为人们所接受的理论是：宇宙起源于一次大爆炸，这次大爆炸将物质投射到四面八方。
然后，原子开始形成并结合成恒星和其他天体。
For several billion years after the "Big Bang", the earth was still just a cloud of dust. What it was to 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, nitrogen, water vapour and other gases, which were to make the earths atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.大爆炸后好几十亿年过去了，但地球还只是一团尘埃。
英语必修三第四单元太空演讲作文
英语必修三第四单元太空演讲作文英文回答：As a student, I believe that space exploration is crucial for the advancement of human knowledge and technology. The exploration of space has led to numerous scientific discoveries and technological advancements that have improved our lives in many ways. For example, GPS technology, which we use every day for navigation, was originally developed for space exploration.Furthermore, space exploration has the potential to inspire future generations and ignite a passion for science and discovery. Just think about the iconic moment when Neil Armstrong first set foot on the moon it captured the imagination of people around the world and inspired countless individuals to pursue careers in science and engineering.In addition, space exploration can also help us betterunderstand our own planet and address pressing issues such as climate change. Satellites and space missions provide valuable data that can help us monitor changes in the environment and develop solutions to protect our planet for future generations.Overall, I believe that space exploration is not only important for scientific and technological progress, but also for inspiring curiosity and fostering a sense of wonder about the universe.中文回答：作为一名学生，我认为太空探索对于人类知识和技术的进步至关重要。

A tree diagramSection 2: Background information for Unit 4Astronomy: the science of the stars1. THE PLANETS 行星Although we live in a very small piece of the Universe, it's still where we call home and it's a very interesting place. The nine planets that make up our solar system range from very tiny rocky planets to huge gas giants featuring fascinating ring systems.Mercury 水星Mercury is the closest planet to the Sun・ Its surface has many thousands of impact craters as a result of being bombarded by objects since the solar system's early days. Since Mercury has no protective atmosphere, the temperature on the surface ranges from extremely hot on the side facing the Sun to extremely cold on the side that faces away from the Sun.Venus金星（太白星）Venus is named after the Roman goddess of love and beauty. This is one of those cases where beauty is only skin deep, though, as the surface of Venus is a very unpleasant place featuring very high temperatures, winds that blow hundreds of miles per hour and an atmosphere of sulfuric acid. Venus is an example of run away greenhouse effect on a planetary scale ・Earth地球People always say there's no place like home. Our home planet is a very beautiful place with the most varied surface in the entire solar system・ From a distance, our planet looks like a beautiful big blue marble.Mars火星The Red Planet is named after the Roman god of war. Its distinctive rust color is easily seen through a small telescope・ The surface of Mars features many mountains, canyons and even polar ice caps that look a lot like those here on Earth. In ancient times, Mars may have harbored some kind of life, and there is a lot of research going on now trying to get a definitive answer as to whether we are the only life forms in the solar system.Jupiter 木星Jupiter is the largest planet in our solar system. It has at least sixty-one moons and features the Great Red Spot, which is a huge "storm" that has been observed from here on Earth for over three hundred years.Saturn 土星Saturn is one of the most beautiful planets in the solar system・Its fascinating system of rings have been a source of wonder since we first saw them with the earliest telescopes・ Although therings look fairly simple through a small telescope, spacecraft pictures have revealed that what looks like two rings through a telescope is actually hundreds of individual ring systems. In addition, Saturn has so many moons that it is like a miniature solar system.Uranus天王星Uranus is one of the giant gas planets in the solar system. Its mysterious blue-green color provides very few clues as to what is going on underneath the surface clouds・ Uranus also has a very faint ring system that we didn't know existed until the planet was visited by the Voyager spacecraft・Neptune海王星Neptune was the last stop the Voyager mission made before if left our solar system・ What we found out from Voyager was that Neptune has winds that blow hundreds of miles per hour and a moon that features 八geysers” of nitrogen that enipt and leave dark marks on the surface・Pluto冥王星Pluto is the smallest and most mysterious planet in our solar system. Pluto is so far away that the Sun is just a dim point of light that looks a lot like any other star. Pluto has one moon, Charon, that is almost as big as the planet itself.2. The Big Bang TheoryThe Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions.In 1927, the Belgian priest Georges Lemaire was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lemaire's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance.The big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself)・The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery-Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions・。
