Section C
Changes in Beijing
I'm Kangkang. For this report I have interviewed my grand-mother. She has lived in Beijing for more than forty years. She has seen the changes in Beijing herself.
In the 1960s, the living conditions in the city were poor. The roads were narrow and there weren't many ring roads. Big families were crowded into small houses. Many families couldn't get enough food. Few children had the chance to receive a good education. People had little money to see a doctor. And there were few hospitals. People kept in touch with their friends and relatives far away mainly by letter or telegram.
China has developed rapidly since the reform and opening-up. More and more ring roads and subways have appeared and buildings in Beijing are becoming taller and brighter. People's living conditions have improved a lot. And there are more kinds of food and clothes to choose to satisfy people’s needs. Children can study not only in modern schools but also on the Internet. People can enjoy good medical care. What's more, communications are becoming easier and quicker--people can use telephones, cellphones, fax machines and the internet.
Beijing has made rapid progress and it has already succeeded in hosting the 2008 Olympic Games. I think it is important to remember the past, live in the present and dream about the future.
我是康康。为了这份报告，我采访过我的奶奶。她已经在北京居住四十多年了。她亲自眼目睹了北京的变化。
在20世纪60年代，城市的生活条件较差。道路狭窄并且没有很多的环形公路。一个大家庭挤在一间小房子里。许多家庭得不到足够的食物，极少的孩子有机会接受良好的教育。人们几乎没有钱去看医生，而且医院很少。人们主要靠信件或电报与远方的亲友保持联系。
自从改革开放以来，中国发展迅速。出现了越来越多的环形路，并且北京的楼房变得又高又明亮。人们的生活条件有了很大改善了。可供人们挑选的食品和衣物的种类也越来越多。
孩子们不仅能在现代化的学校里学习，而且还能在网上学习。人们可以享受更好的医疗保健。另外，通讯更加方便快捷---人们可以用电话、手机、传真机和网络方式（联系）。
北京取得了快速的进步，它还成功举办了2008年的奥运会。我认为记住过去、立足现在、展望未来非常重要。

Wow! What a large population! 哇！多么庞大的人口啊！
What? 什么？
Look, it says the world has a population of 6.8 billion. And it is increasing by 80 million every year.看！报纸上说世界人口已经达到68亿了，并且正以每年8000万的速度增长。

309 million.美国有3.09亿。

Section C
In 2010, the world's population was about 6.8 billion. More than three billion people live in Asia now. That's almost half of the world's population.
China has the largest population in the world, and about one fifth of the people in the world live in China. Because of the large population, there is less living space for each family. And it is difficult for lots of people to find jobs. At the same time, the large population has caused many other difficulties for the whole nation. For example, it is hard for China to supply energy and the traffic is much heavier. Natural environment are becoming worse and worse. The large population has been a serious problem.
So far, our government has taken many measures to control the population. One is known as the one-child policy. It has worked will in controlling China's population. Thanks to the policy, China is developing quickly and people's living conditions are improving rapidly. However, the population problem is still serious in China. We still have a long way to go.
2010年，世界人口大约是68亿。现在30多亿人居住在亚洲。这几乎是世界人口的一半。
中国是世界上人口最多的国家，世界上大约五分之一的人居住在中国。由于人口多，每个家庭的居住面积更小了。并且许多人找工作都很困难。.同时，人口多也给整个国家带来了许多其他的困难。例如，中国很难提供足够的能源和水来满足人们的日常需求。大多数城市比以前更拥挤，交通堵塞更严重。自然环境越来越糟糕。人口过多已经成为一个严峻的问题。
到目前为止，我们政府已经采取许多措施来控制人口增长。其中一项众所周知的就是独生子女政策。它在控制中国人口数量方面有了显著的成效。多亏了这项政策，中国正在迅速发展，人们的生活条件也在迅速改善。然而，人口问题在中国仍然很严峻，我们仍然有很长的路要走。

Section C
One of the most basic human needs is a home. A home is a safe place. While most people around the world value their homes, there are many people in every country who are homeless.
Some people are homeless for a short period of time because they are moving from one place to another, and other people are not able to find a home. They must live on the streets or in a shelter.
There are many causes of homelessness. Sometimes people can not keep a home because they do not earn enough money, or because they do not have a job. Sometimes people are homeless because they have a problem with drugs or because they have a mental illness. No one is ever homeless on purpose.
Whatever the cause of homelessness is, the effects are the same. Homeless people must work very hard to live. They can not raise their children. Sometimes they must steal food just to eat. The government in every country has worked for many years to support the homeless but more needs to be done. We must think of the homeless as people, not just as problems.
人类最基本的需求之一是家。家是一个安全的地方。尽管世界上大多数人都珍视他们的家，但是每个国家却总有很多无家可归的人。
有些人只是短时间的无家可归，因为他们从一个地方搬到另一个地方，而其他的人没有能力找到家。他们必须住在街上或收容所。
有许多原因造成无家可归。有时不能养家是因为他们没有挣到足够的钱，或者因为他们没有工作。有时人们无家可归是因为他们存在毒品问题或是精神疾病。在任何时候都没有人想故意无家可归。
不管是什么原因造成了无家可归，其结果总是相同的。无家可归的人必须努力地维持生计。他们养不起孩子，有时他们必须偷东西吃。多年以来，每个国家的政府都在设法援助这些无家可归的人，但需要做的还很多。我们必须关心无家可归的人，而不是仅仅把无家可归视为（社会）问题。

Section C
In today’s world, almost everyone knows air pollution is harmful to people’s health. However, not all people know noise is also a kind of pollution and is harmful to humans’ health.
People who work and live in noisy conditions often go deaf. For example, many of the workers who print newspapers and books lose their hearing. Quite a few people living near airports also have hearing loss. Recently, it is reported that many teenagers in America can hear no better than 65-year-old people do, because these young people always listen to loud pop music.
Making a loud noise in public is also a kind of pollution. It not only disturbs others but also does great harm to people’s hearing. Cars and machines also produce too much noise. Such pollution makes people feel uncomfortable and unpleasant, and it can even cause them to become sick or deaf. Nowadays, many countries are trying to solve all sorts of environmental problems, including noise pollution.
在当今世界，几乎每个人都知道，空气污染对人们的健康有害。然而，并不是所有的人都知道噪声也是一种污染并且对人类的健康一样有害。
在噪音条件下工作和生活的人经常变聋。例如，印刷报纸和书的工人多数失去听力。很多生活在机场附近的人也丧失了听力。近来，有报道说，美国许多青少年的听力几乎和65岁的老人一样差，因为这些年轻人总喜欢听劲爆的流行音乐。
在公共场制造太大的噪音也是一种污染。它不仅打扰了别人，而且严重损害听力。汽车和机器也会产生很多噪音，这样污染使人们感到不舒服，不愉快，甚至可能使他们生病或变聋。现在，许多国家正在努力解决各种环境问题，包括噪音污染。

The earth is 4.6 billion years old. We humans have lived on the earth for only 35 000 years, but during this period, we have changed our planet a lot in many ways. Some things we have done are very good for the earth while others are bad.
All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so many kinds of animals and plants are disappearing.
In big cities, cars and buses have polluted the air. Now many people in cities have health problems.
Factories have also polluted the land and the water. As a result, many rivers and lakes are now dead.
Around the earth, there’s a special kind of oxygen called “ozone”(O3). It is important to the earth. But now air pollution is destroying it and making a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer.
Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal and wood. This has formed a “blanket” around the earth. The heat from the sun can’t escape so the temperature is rising. This is called “the greenhouse effect”. It causes the level of the oceans to rise and the climate of the earth to change.
All these problems are very serious, so we must do something now.
地球已有46亿年了。我们人类生活在地球上只有三万五千年，但是在此期间我们在许多方面改变了我们的星球。我们所做的一些事情对地球有益，然而其他一些对地球却有负面影响。
全世界的人们已经砍掉了数百万的树木。下雨或吹风时，土壤被带走，森林变成了荒漠，因此许多种类的动植物正在灭绝。
在大城市，小车和公交车污染了空气，现在城市里许多人都有健康问题。
工厂也污染了土地和水。结果，现在许多河流和湖泊失去了生机。
地球周围有一种特殊的氧气叫做“臭氧” (O3)，它对地球很重要。但现在空气污染正在破坏它，而且使臭氧层出现了一个非常大的洞。大量来自太阳的有害射线穿过这个洞直接进入地球大气层。这是非常危险的，因为这种射线能导致癌症。
空气中的二氧化碳(CO2)大量增多。二氧化碳主要来自燃烧的油、煤和木柴。它在地球周围形成毯子式的覆盖层。来自太阳的热量不能散发，所以气温度升高。这就是所谓的“温室效应”。它会引起海平面升高而且地球上的气候也会有变化。
所有这些问题都非常严重，所以我们现在必须做些事情（来保护我们的家园）。

We all know that you’re working for an organization that protects the environment. Can you tell us what you are doing there?我们都知道你在为一个环境保护组织工作。你能告诉我们你在那儿做什么工作吗？

In many countries, people produce power from coal, but it is very dirty and causes acid rain. Some countries use nuclear energy to produce power. However, nuclear power can be very dangerous. To solve the energy problem, people all over the world are looking for new ways to produce power.
China is one of the first countries in the world to use biogas technology. Farmers recycle straw, grass and animal waste to make biogas. This renewable energy is used in people’s everyday lives. Its key disadvantage is that the process requires a long time (up to 30 days) and the cost is high.
Electric vehicles were developed in the 1990s. On April 11, 2010, a new kind of vehicle named “Yezi” was shown in the 2010 Shanghai World Expo. It produces electricity from the sun, the wind and CO2. It can not only protect the environment but also save energy. It’s too small to hold many people, but larger models will be developed in the near future.
In China, the best-known maglev train is the German-built one in Shanghai. It takes people just 7 minutes to go to the airport 30 km away. The train can reach a top speed of 431 km per hour. It is quiet and quick. There is no wheel noise, because there are no wheels. Maglev trains are very energy-efficient and do not pollute the air. However, maglev guide paths are much more expensive than traditional steel railways.
在许多国家，人们用煤来生产动力，但是这种方法很脏并且会导致酸雨。一些国家使用核能源来生产动力，然而，核能却非常危险。为了解决能源问题，全世界的人们都在寻找新的方法来生产动力。
中国是世界上最早使用生物技术的国家之一。农民们回收麦杆、草和动物粪便来制作生物气，这种可再生能源被应用到人们每题的生活当中去。它的主要缺点是这个过程很长（长达30天），并且建设费用高。
电动车辆是在20世纪90年代被发明的。2010年4月11日，一种新型的电动车“叶子”在上海世博会上展出。它通过太阳、风和二氧化碳发电。它不仅环保，而且节约能源。它太小，不能承载太多的人，但是，在不久的将来，更大的车型将会被研制出来。
在中国，最有名的磁悬浮列车由德国建造，在上海投入使用的那辆。仅用7分钟这辆车就可以将人们送30千米以外的机场。这辆车最高速度可达431千米，它安静并且快速。它不会产生车轮的噪音，因为它根本没有车轮。磁悬浮列车能够有效利用能源而且不会污染空气。然而，悬浮轨道的建设费用却远远高于传统铁轨的建设费用。

An invention may be a new product or a new way of doing things. Inventions come about in many ways.
一项发明可以是一种新产品或者一种做事的新方法。发明会以各种方式出现。
Most of the time, inventions happen because someone works to solve a problem. Sometimes inventions are the result of accidents. Look at your schoolbags. You have pencils, pens, crayons, rulers and some books. None of these things was planted in fields. They were made in factories and invented by someone.
多数情况下，出现一项发明是因为有人努力去解决一个问题。有时候发明是意外的结果。看看你的书包。你有铅笔、钢笔、蜡笔、尺子和一些书。这些东西没有一样是天然存在的。它们是在工厂里制造出来，被人们发明出来的。
Inventing is interesting and exciting and everyone can be an inventor.
发明既有趣又令人兴奋，每个人都可以是一位发明家。
Do you want to be an inventor? These are a few simple steps to follow in the invention process.
你想成为发明家吗？这些是在发明过程中要经历的一些简单步骤。
You can have wild and crazy thoughts. Remember that no idea is too silly. Many people laughed at the Wright brothers and said they would never fly. But they weren't discouraged by what people said. That's why now we have planes.
你可以有疯狂又大胆的想法。记住没有什么想法是愚蠢的。很多人曾嘲笑莱特兄弟，说他们永远都飞不起来。但是他们并没有被人们的话打击。所以现在我们有了飞机。
Careful planning is important in the invention process. This is the time to brainstorm for idea and to evaluate them.
认真计划是发明过程中很重要的一点。也就是说要集思广益，评估观点。
Make a detailed drawing of your invention so others will understand how your invention works. Make a model of your invention. See if your invention works as it is planned. If not, do more research, redesign it, and test it again.
把你的发明详细画出来，这样别人就能懂它是如何运作的。为你的发明做一个模型。看你的发明是否能像计划的那样工作。如果不能，就继续研究，重新设计，再次测试。
Every invention needs a name. Share your inventions with others.
每项发明都需要名字。跟大家分享你的发明。

What do you know about Mars? What does it look like? Mars is the fourth planet from the sun in our solar system and is named after Mars, the Roman god of war. Its diameter is 53% as wide as that of the earth. Mars goes around the sun at a distance of about 228 million kilometers.
关于火星你了解多少？火星是什么样的？火星是太阳系中距离太阳第四的星球，以罗马战神的名字“Mars”命名。火星的直径是地球的53%。火星在距离太阳2.28亿千米的轨道上绕行。
You can tell which planet is Mars because it is bright red in the night sky. It looks like a red and orange ball. It's very beautiful. But during spring and summer, the surface of Mars is covered by strong storms.
火星在夜空中是明亮的红色，很好识别。它看起来像一个橘红色的大球。很漂亮。但是春夏季时，火星表面覆盖有厚厚的云层。
The gravity on the surface of Mars is about two-fifths as strong as it is on the earth. So a person who weight 90 kilos on the earth weights only 36 kilos on Mars. The temperature on Mars is between -138℃ and 28℃. The air has only 0.13% oxygen.
火星表面的重力大概是地球的1/5。所以在地球上有90公斤重的人在火星上只有36公斤。火星上的温度大约在-138℃ 到 28℃之间。空气中含氧量只有0.13%。
It takes a spaceship about eight months to reach Mars from the earth when the two planets are closest to each other. Scientists are still searching for more information about Mars.
火星与地球相距最近时，宇宙飞船需要八个月才能从地球抵达火星。科学家们还在探索更多关于火星的信息。

科学家认为生命已经在地球上存在了数百万年。但是，人类还没有在其他星球上发现生命。地球是行星，围绕太阳运行。还有另外七个行星也绕着太阳运行。
The sun and its planets are called the solar system. The solar system is a small part of the universe.
太阳以及围绕它运行的行星被称为太阳系。太阳系只是宇宙的一小部分。
Scientists have launched many spaceships to explore other planets in the solar system. Some spaceships have gone beyond the solar system. However, no one has discovered any life in space yet.
科学家们发射了很多宇宙飞船，去探索太阳系中的其他星球。有些宇宙飞船已经飞出了太阳系。但是，还没有人在太空中发现任何生命。
Why has no one from other planets sent us a message? Have they tried to send information to us? With so many stars in space, are we alone, or is there life on other planets in space?
为什么其他星球上没有任何人给我们发信息呢？他们有试过给我们发信息吗？太空中有这么多行星，我们是唯一的生命吗？还是其他星球上也有生命？
