Unit 4 Astronomy: the science of the stars
HOW LIFE BEGAN ON THE EARTH
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.
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 and 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 dioxide, 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 generally 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 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.
A VISIT TO THE MOON
Last 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 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 weight 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”

Module 1 Reading The City of the Future What will the city of the future look like No one knows for sure, and making predictions is a risky business. But one thing is certain— they are going to get bigger before they get smaller. In the future, care for the environment will become very important as earth's natural resources run out. We will use lots of recycled materials, such as plastic, aluminium, steel, glass, wood and paper, and we will waste fewer natural resources. We will also have to rely more on alternative energy, such as solar and wind power. All this seems certain, but there are plenty of things about city life in the future which are not certain. To find out what young people think about the future of urban life, a teacher at a university in Texas in the United States asked his students to think how they would run a city of 50,000 people in the year 2025. Here are some of the ideas they had: Garbage ships To get rid of garbage problems, the city will load huge spaceships with waste materials and send them towards the sun, preventing landfill and environmental problems. Batman Nets Police will arrest criminals by firing nets instead of guns.
Unit 1 Festivals around the world FESTIVALS AND CELEBRATIONS Festivals and celebrations of all kinds have been held everywhere since ancient times. Most ancient festivals would celebrate the end of cold weather, planting in spring and harvest in autumn. Sometimes celebrations would be held after hunters had caught animals. At that time people would starve if food was difficult to find, especially during the cold winter months. Today’s festivals have many origins, some religious, some seasonal, and some for special people or events. Festivals of the dead Some festivals are held to honour the dead or to satisfy the ancestors, who might return either to help or to do harm. For the Japanese festival Obon, people should go to clean graves and light incense in memory of their ancestors. They also light lamps and play music because they think that will lead the ancestors back to earth. In Mexico, people celebrate the Day of the Dead in early November. On this important feast day, people eat food in the shape of skulls and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The Western holiday Halloween also had its origin in old beliefs about the return of the spirits of dead people. It is now a children’s festival, when they can dress up and go to their neighbours’ homes to ask for sweets. If the neighbours do not give any sweets, the children might play a trick on them. Festivals to Honour People Festivals can also be held to honour famous people. The Dragon Boat Festival in China honours the famous ancient poet, Qu Y uan. In the USA, Columbus Day is in memory of the arrival of Christopher Columbus in the New World. India has a national festival on October 2 to honour Mohandas Gandhi, the leader who helped gain India’s independence from Britain. Harvest Festivals Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter and the agricultural work is over. In European countries, people will usually decorate churches and town halls with flowers and fruit, and will get together to have meals. Some people might win awards for their farm produce, like the biggest watermelon or the most handsome rooster. China and Japan have mid-autumn festivals when people admire the moon and in China enjoy moon-cakes. Spring Festivals The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. At the Spring Festival in China, people eat dumplings, fish and meat and may give children lucky money in red paper. There are dragon dances and carnivals, and families celebrate the Lunar New Year together. Some Western countries have very exciting carnivals, which take place forty days before Easter, usually in February. These carnivals might include parades, dancing in the streets day and night, loud music and colourful clothing of al kinds. Easter is an important religious and social festival for Christians around the world. It celebrates the return of Jesus from the dead and the coming of spring and new life. Japan’s Cherry Blossom Festival happens a little later. The country, covered with cherry tree flowers, looks as though it is covered with pink snow. People love to get together to eat, drink and have fun with each other. Festivals let us enjoy life, be proud of our customs and forget our work for a little while.

The most ancient festivals would celebrate the end of the cold weather, planting in spring and harvest in autumn. Other celebrations were held when hunters could catch animals. They would starve if food was difficult to find, so they celebrated when they had food. They lit fires and made music because they thought these festivals would bring a year of plenty.

In Japan the festival is called Obon, when people should go to clean the graves and light incense in memory of their ancestors.

They dress up and try to frighten people. If they are not given anything, the children might play a trick. Festivals to Honour People Festivals can be held as an honour to famous people or to the gods. One of these is the Dragon Boat Festival in China, which honours the famous ancient poet, Qu Yuan. Another is Columbus Day in the USA, in memory of the arrival of Christopher Columbus in America. In India there is a national festival on October 2 to honour Mahatma Gandhi, the leader who helped gain India’s independence from Britain. Harvest Festivals Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter ,and because a season of agricultural work is over. In European countries it is the custom to decorate churches and town halls with flowers and fruit, and people get together to have meals. Some people might win awards for their animals, flowers, fruits and vegetables, like the biggest watermelon or the most handsome rooster. In China and Japan there are mid-autumn festivals, when people admire the moon and give gift of mooncakes. Spring Festivals The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring.

It celebrates the return of Jesus for Christians and it also celebrates the coming of spring. In Japan, the Cherry Blossom Festival happens a little later. The country is covered with cherry tree flowers so that it looks as though it might be covered with pink snow. People love to get together to eat, drink and have fun with each others. Festivals let us enjoy life, be proud of our customs and forget our daily life for a little while.

新人教版高中英语课文译文 必修四 第一单元卓有成就的女性 Reading 非洲野生动物研究者 清晨5点45分，太阳刚从东非的贡贝国家公园的上空升起，我们一行人准备按照简研究黑猩猩的方法去森林里拜访它们。简研究这些黑猩猩家族已经很多年了，她帮助人们了解了黑猩猩跟人类的行为是多么的相似。我们当天的首相任务就是观察黑猩猩一家是如何醒来的。这意味着我们要返回前一天晚上我们离开时黑猩猩睡觉的大树旁。大家坐在树荫下等待着，这时候黑猩猩睡醒了，准备离开。然后这群黑猩猩向森林深处漫步而去，我们尾随其后。在大部分时间里，黑猩猩或互相喂食，或彼此擦身，这在它们的家族里是爱的表达方式。简预先提醒我们，到下午的时候我们就会又脏又累。她说对了，但是到了傍晚时分我们就觉得这一切都是值得的。我们看到黑猩猩妈妈跟她的幼子们在树上玩耍，后来看见它们一起回窝里睡觉了。我们明白了黑猩猩家庭成员之间的联系像人类家庭一样紧密。 在简之前没有人完全了解黑猩猩的行为。她花了多年的时间来观察并记录黑猩猩的日常活动。从孩提时代起，简就想在动物生活的环境中研究它们。但是，这不是一件简单的事。当她1960年最初来到贡贝时。对女性来说，住进大森林还是很稀罕的事情。她母亲头几个月来帮过她的忙，这才使她得以开始自己的计划。她的工作改变了人们对黑猩猩的看法。比方说，她的一个重要发现是黑猩猩猎食动物。而在此之前，人们一直认为黑猩猩只吃水果和坚果。她曾经亲眼看到
过一群黑猩猩捕杀一只猴子，然后把它吃掉。她还发现了黑猩猩是如何交流的，而她对黑猩猩身势语的研究帮助她勾勒出黑猩猩的社会体系。 40年来，简·古道尔一直在呼吁世人了解并尊重这些动物的生活。她主张应该让野生动物留在野外生活，而不是用于娱乐或公告。她还为黑猩猩建起了可以安全生活的专门的保护区，她的生活是忙忙碌碌的，然而，正如她所说的：“我一旦停下来，所有的一切就会涌上心头。我就会想起实验室的黑猩猩，太可怕了。每当我看着野生黑猩猩时，这个念头总是萦绕着我。我会对自己说：…难道它们不幸运吗？?然后我就想起了那些没有如何过错却被关在笼子里的小 黑猩猩。一旦你看到这些，你就永远不会忘记……。” 简已经得到了她想要得到的一切：在动物的栖息地工作：获得博士学位；还向世人证明女人和男人一样也能在森林里生活。她激励着人们为妇女们的成就而喝彩。 Using Language 为什么不继承她的事业？ 上学时我喜欢英语、生物和化学，但是我进大学该选哪门专业呢？直到有一天晚上坐在电脑旁研究中国的伟大女性时，我才有了答案。 很偶然地，我看到了一篇关于林稚巧大夫的文章。她是妇科专家，1901年生，1983年去世。林稚巧似乎一直都在为自己选择的事业而奔忙，去国外留学，写了很多书和文章。其中有一本书引起了我的注意。这是一本小书，介绍如何从妇女怀孕到护理婴儿的过程中降低死亡率，她提出了一些可以遵循的简单的做法，保持婴儿清洁和健康，让他们远离疾病。她为什么要写这些东西呢?林稚巧认为哪些妇女会需要这些忠告呢？我仔细地看了这篇文章，了解到那是为农村妇女写的。也许是她们在遇到紧急情况时找不到医生。
Unit 1 Women of achievement Reading A STUDENT OF AFRICAN WILDLIFE It is 5:45 am and the sun is just rising over Gombe National Park in East Africa. Following Jane's way of studying chimps, our group are all going to visit them in the forest. Jane has studied these families of chimps for many years and helped people understand how much they behave like humans. Watching a family of chimps wake up is our first activity of the day. This means going back to the place where we left the family sleeping in a tree the night before. Everybody sits and waits in the shade of the trees while the family beings to wake up and move off. Then we follow as they wander into the forest. Most of the time, chimps either feed or clean each other as a way of showing love in their family. Jane warns us that our group is going to be very tired and dirty by the afternoon and she is right. However, the evening makes it all worthwhile. We watch the mother chimp and her babies play in the tree. Them we see them go to sleep together in their nest for the night. We realize that the bond between members of a chimp family is as long as in a human family. Nobody before Jane fully understood chimp behaviour. She spent years observing and recording their daily activities. Since her childhood she had wanted to work with animals in their own environment. However, this was not easy. When she first arrived in Gombe in 1960, it was unusual for a woman to live in the forest. Only after her mother came to help her for the first few months was she allowed to begin her project. Her work changed the way people think about chimps. For example, one important thing she discovered was that chimps hunt and eat meat. Until then everyone had thought chimps ate only fruit and nuts. She actually observed chimps as a group hunting a monkey and then eating it. She also discovered how chimps communicate with each other, and her study of their body language helped her work out their social system. Four forty years Jane Goodall has been outspoken about making the rest of the world understand and respect the life of these animals. She has argued that wild animals should be left in the wild and not used for entertainment or advertisements. She has helped to set up special places where they can live safely. She is leading a busy life but she says: “Once I stop, it all comes crowding in and I remember the chimps in laboratories. It's terrible. It affects me when I watch the wild chimps. I say to myself, ‘Aren't they luck?' And then I think about small chimps in cages though they have done nothing wrong. Once you have seen that you can never forget…” She has achieved everything she wanted to do: working with animals in their own environment, gaining a doctor's degree and showing that women can live in the forest as men can. She inspires those who want to cheer the achievement of women. Using language WHY NOT CARRY ON HER GOOD WORD? I enjoyed English, biology, and chemistry at school, but which one should I choose to study at university? I did not know the answer until one evening when I sat down at the
