Ten students will deliver their speeches onthe given topic “Man and Nature”. I would appreciate it if you could accept our invitation. If you have any questions, please contact me at 44876655. I am looking forward to your early reply.HOW LIFE BEGAN ON THE EARTH1. No one knows exactly______ the earth began, as it happened so long ago. However, according to a _____ (wide) accepted theory, the universe began with a "Big Bang" ______ 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. ____ 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 ___violent that it was not clear ______ 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, _____ were to make the earth's atmosphere. _____ is even more important is _______ as the earth cooled down, water began to appear on its surface.Water had also appeared on other planets like Mars but, ______(不像)the earth, it had disappeared later. It was not ______ (immediate) obvious that water was to be fundamental to the _______(develop)of life. ______many scientists believe is _____the continued presence of water allowed the earth to dissolve______ (harm) gases and acids into the oceans and seas. This produced a chain reaction, which made ____possible for life to develop.2. 改错 Many millions of years late, the first extreme small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, that encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow in land. They are followed in time by land animals. Some were insects. The others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared the first time. They produced young generally by lay 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 remain a mystery. This disappearance made the rise of mammals possible 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 it.(10处)3. 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 _____ 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, _____ prevents heat from escaping from the earth into space. As _____result of this, many scientists believe the earth may become too hot to live on. So ______life will continue on the earth for millions of years to come will depend on ______this problem can be solved.A VISIT TO THE MOON4. Last month I was lucky enough to have a chance _____( 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 _____ me that the force of gravity would change three times on our journey and _____ 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 _____ pull of the earth's gravity. It was _____ hard that we could not say anything to each other. _______ (Gradual) the weight lessened and I was able to talk to him. "Why is the spaceship not falling back 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 ____ _____ 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 float weightlessly around in our spaceship cabin ______ (watch) the earth become smaller and the moon larger.5. 短改 When we got there, I wanted to explore immediate. "Come on," I said. "If you are right, my weight will be less than on the earth because the moon is small 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 climb down the steps from the spaceship. So when I tried to step forward, I found I was carried twice so far as on the earth and fell over. "Oh dear," I cried, "walking does need a bit practice now that gravity has changed." After a while I got the hang of it and we began to enjoy us. (7处)6. _______ ( Leave) the moon's gravity was not as______ (pain) as leaving the earth's. But returning to the earth was very_______( frighten). We watched,______ (amaze) 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 _____ land. "That was very______ (exhaust) 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, "_____ star would you like to go to?"用适当的连接词完成句子。
