• Dear Headmaster, I'm writing to tell you something important. Nobody likes to be untidy. However, some students throw waste paper and bottles everywhere. We all need a quiet place to study, but some students often make too much noise at school. Worst of all, some of them are quite rude when talking to others. Everyone knows their behavior is bad, but none of us knows how to stop them. I think we should make rules to change the situation. Anyone who breaks the rules will be punished. Perhaps it will be hard for us to obey the rules in the beginning, but if everyone does his or her best to follow the rules, our school environment will improve. Sincerely, Kangkang

  尊敬的校长， 我写信是想告诉你一些重要的事情。没有人喜欢凌乱的地方。然而，有些学生到处扔废纸和瓶子。我们都需要一个安静的地方学习，但有些学生经常在学校里制造太多噪音。最糟糕的是，有些人在与他人交谈时很粗鲁。大家都知道他们的行为很糟糕，但没有一个人知道如何阻止他们。 我认为我们应该制定规则来改变这种情况。任何违反规则的人都会受到惩罚。也许一开始我们很难遵守规则，但如果人人都尽最大努力遵守规则，我们的学校环境就会改善。 谨上， 康康

• The earth is 4.6 billion years old. We humans have lived on the earth for only 35000 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.

  地球46亿岁了。我们人类在地球上只生活了35000年，但在此期间，我们在很多方面已经改变了“我们的星球”。我们做的一些事情对地球有益，而另一些是有害的。

• 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.

  在全世界，人们砍伐了数以百万计的树木。当下雨或刮风的时候，沙土被吹走。森林变成了沙漠，许多动物和植物正在消失。

• 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.

  工厂也污染了土地和水。结果，许多河流和湖泊现在都死了。

• 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.

  在地球上，有一种特殊的氧气称为“臭氧”（O3）。它对地球很重要。但现在空气污染正在破坏它，并在臭氧层中造成了一个非常大的洞。太多来自太阳的有害射线穿过臭氧洞直接到达地球。这是非常危险的，因为这种辐射会导致癌症。

• 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.

  空气中的二氧化碳（CO2）增加了很多。它主要来自燃烧石油，煤和木材。这就在地球周围形成了“覆盖层”。太阳的热量无法散发出去，所以温度上升。这就是所谓的“温室效应”。它引起海平面上升，地球气候的变化。

• All these problems are very serious, so we must do something now.

  大海似乎是最好的答案。海洋中有大量的水。但我们需要从海水中取出盐。这很贵。如果科学家们能找到更便宜的方法来做，我们就可以解决水资源短缺的问题。

• How can we avoid a serious water shortage? First, we should save water and not waste it. Second, we should protect our water resources and not pollute them. Third, we should discover ways to reuse water. Scientists have made some progress in this field. Today, some large cities are reusing their water. But people's need for water is increasing day by day. We still don't have enough water. What else can we do?

  我们怎样才能避免严重的水资源短缺情况？首先，我们要节约用水，不要浪费。第二，我们要保护水资源，不要污染水。第三，我们应该发现再次使用水的方法。科学家在这个领域中已经取得了一些进展。今天，一些大城市重复使用水。但人们对水的需求日益增加。我们还没有足够的水。我们还可以做些什么？

• Although the world is hungry, it is even thirstier. While nearly 3/4 of the earth is covered with water, we are still short of drinking water. This is because about 97% of the water on the earth is sea water. So we can't use it for watering plants or drinking directly. Humans can only drink and use fresh water from places including rivers, lakes and underground.

  纵然世界很饥饿，但是它更渴。虽然近3/4的地球表面被水覆盖，我们仍然缺乏饮用水。这是因为地球上97%的水是海水。所以我们不能直接用它为植物浇水或饮用。人只能喝并使用来自河流、湖泊以及地下这些地方的淡水。

• Forests are the lungs of the earth. Without them, it cannot breathe. It needs its forests to remove carbon dioxide from the air and to make oxygen. In many countries, such as New Zealand, Canada, and Brazil, forests were cut down to provide wood to build houses. Many volunteers around the world are working in their holidays to plant new trees to replace them.

• They face many difficulties when planting new trees. The weather may be very hot and dry or it may be very cold and wet. There are often many insects that bite these planters on their legs, arms, and faces while they work. They carry heavy bags of small trees, and working in the mountains can be dangerous.

  在种植新树的时候，他们面临着许多困难。天气可能会非常炎热和干燥或可能非常寒冷和潮湿。当他们工作的时候，经常有许多昆虫咬这些植树人的腿、手臂和脸。他们背着装有小树苗的沉重的袋子，在山上工作是非常危险的。

• Chinese volunteers have helped plant lots of trees around the world. They have big plans to grow more forests and have used new technologies to reach their goals. By planting millions of trees every year, they are not only making their own environment better but also helping the whole world. This shows that Chinese really care about the earth.
