The harder you throw the tennis ball, the faster it is travelling when it leaves your hand and the higher the ball will go before turning back. If you throw it hard enough it will never return, the gravitational attraction will not be able to pull it back down. The velocity the ball must have to escape is known as the escape velocity and for the earth is about 7 miles a second.As a body is crushed into a smaller and smaller volume, the gravitational attraction increases, and hence the escape velocity gets bigger. Things have to be thrown harder and harder to escape. Eventually a point is reached when even light, which travels at 186 thousand miles a second, is not travelling fast enough to escape. At this point, nothing can get out as nothing can travel faster than light. This is a black hole.任务一参考答案：基础知识默写基本单词1. system2. theory3. atmosphere4. unlike5. chain6. climate7. crash8. pull9. float 10. thus 11. globe 12. fundamental 13. 乘；相加14. 物理学家15. 重力；万有引力派生单词16. violent; violence 17. harmful; harm 18. exist; existence 19. puzzle; puzzling; puzzled短语1. in timey legs3.give birth to4. in one’s turn5. prevent…from6. cheer up7.now that 8. break out 9. watch out for任务二参考答案：课堂检测题Ⅰ.Mercury水星Venus金星Earth地球Mars火星Jupiter木星Saturn土星Uranus天王星Neptune海王星。

3月3日导学案Book3 Unit4 Period 2自学Unit 4Astronomy:the science of the stars ----Reading ：How life began on the earth课文原文：HOW 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 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 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 enerally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than 140 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.Period 2 预习导学预习目标：Book3 Unit4 Reading文章较长，请同学们对文章进行课前预习，了解文章的主旨大意。

3月5日导学案Book3 Unit4 Period 4自学Book 3Unit 4Astronomy:the science of the stars第二篇课文A VISIT TO THE MOON课文原文：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 times on 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 of the earth's gravity. It was so hard that we could not say anything to each other. Gradually the 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 the earth now to feel its pull," he explained, "so we feel as if there is no gravity at all. When we get closer to the 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 mass 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?"Period4预习导学预习目标：掌握下列重点词或词组或句型的用法。
