In some countries of the world, people have started to reduce the amount of garbage they make. How? First, they buy fewer things. They try to buy only what they really need.

People call these the 'three Rs': reduce, reuse and recycle. The three Rs help us remember that pollution is a problem. 翻译：在世界的某些国家，人们已经开始减少他们所制造的垃圾的数量。怎样做呢？第一，他们买的东西更少了。他们试着只买他们真正需要的东西。当你买的东西更少时，你扔掉的东西就更少了。第二，他们重复使用物品。他们使用物品，然后他们会再使用它们！第三，他们回收利用物品。他们把旧物品变为新物品。人们把这些称为“3R原则”：减少，重复使用和回收利用。3R原则帮助我们牢记污染是一个问题。

Bees, ants, doves, dogs and cats — these are all living things. 翻译：自然界充满了生物。生物刚开始又小又虚弱，然后慢慢地变得又大又强壮。你就是一个生物。你的每一个同学都是一个生物。花、草和树木也都是生物。蜜蜂、蚂蚁、鸽子、狗和猫——这些都是生物。

All living things need food and water to grow. Think about yourself. When you are hungry, you need to eat. You eat fruit, vegetables, meat and fish. They can help you grow big and strong. You drink water when you are thirsty. Now think about a tree. When a tree is hungry, it gets food from the soil. Trees drink water, too. 翻译：所有的生物都需要食物和水才可以生长。想想你自己吧。当你饿了的时候，你需要吃。你吃水果、蔬菜、肉和鱼。它们可以帮助你长得又大又强壮。当你渴了的时候，你要喝水。现在想想一棵树吧。当树饿了的时候，它就从土壤中提取食物。树也会喝水。

We are different in some ways, but all living things are connected. We all live on the same planet, and we depend on each other. If we pollute the rivers and oceans, fish may get sick or even die. Some birds live off fish. If the birds eat the sick or dead fish, they may die off. Nature is a balance between all the living things on the planet. If one species dies off, then another species may die off, followed by another, and another... 翻译：我们在某些方面是不同的，但是所有的生物都是相连的。我们都居住在同一个星球上，而且我们相互依赖。如果我们污染了河流和海洋，鱼儿可能就会得病，甚至死亡。一些鸟以鱼为食。如果这些鸟吃了生病或死了的鱼，它们可能会相继死去。大自然是地球上所有生物之间的一个平衡点。如果一个物种灭绝，那么另一个物种可能就会灭绝，接着是另一个，再另一个…

Some animals lost their homes, and they attacked people. Some factories polluted the air, water and people's food. The earth is getting warmer. Some scientists say the sea level will rise by at least 1 metre in the next 100 years. Some houses beside the sea will disappear. 翻译：但是后来，人们砍倒了森林里的树木，杀死了动物，然后建造了工厂和建筑物。他们改变了地球。人们的房子被洪水中的土壤给掩埋了。一些动物失去了它们的家园，于是它们开始攻击人类。一些工厂污染了空气、水和人们的食物。地球正在逐渐变暖。一些科学家说在接下来的100年内海平面将至少上升1米。在海边的一些房子将会消失。

Jenny's blog 翻译：詹妮的博客

This week we learned about pollution. I never knew that garbage was so interesting! On Tuesday, it was World Environment Day. Danny, Brian and I cleaned up the schoolyard. All of our classmates helped. We took bags and picked up the garbage. It was great to see everyone working together! Later that day, Brian, Danny and I went for a walk around our neighbourhood. When we saw garbage, we picked it up. Danny found a used toy car with one broken wheel. He took it home, cleaned it and fixed it. On Wednesday, we sorted our school's garbage. We put on gloves and divided the garbage into different piles: glass, metal, plastic, paper and everything else. Most of the garbage was paper. People wasted a lot of paper! There was less plastic than paper and more plastic than metal. There was the least amount of glass. Today, Danny made a car out of garbage! He used a big box for the body and pieces of wood for the seats. He used a bit of glue to put the wheels on. The wheels were plastic lids. It was great! We throw garbage away. But where does it go? Later this month, we will go on a class trip to the city recycling centre. Thousands of tons of garbage are sent there. We will see the workers sort all of our garbage for recycling. I think it's our duty to protect the environment. I am only one person, but if I do my part, the earth will be a cleaner and safer place. If each of us does something for the environment, all of us will have a better life. Jenny 翻译：本周我们了解到了污染。我从不知道垃圾是如此有趣！ 在星期二，是世界环境日。丹尼、布赖恩和我打扫了校园。我们的所有同学都帮忙了。我们拿着袋子捡垃圾。看见大家共同劳动真好！ 那天晚些时候，布赖恩、丹尼和我去社区周围散步了。当我们看见垃圾时，我们就把它捡起来。丹尼发现了一辆用过的玩具车，其中有个车轮坏了。他把它带回了家，把它洗干净并把它给修好了。 在星期三，我们把学校的垃圾分类了。我们戴着手套，把垃圾分成了不同的堆：玻璃、金属、塑料、纸和其他一切。大多数垃圾都是纸。人们浪费了许多纸！塑料比纸要少，而塑料又比金属要多。玻璃的数量最少。 今天，丹尼用垃圾制成了一辆汽车！他把一个大盒子用来做车身，把几块木头用来做座位。他用一点儿胶水把轮子粘上去。车轮是塑料盖子。真是太棒了！ 我们会把垃圾扔掉。但是它会去哪儿呢？在本月下旬，我们将去城市回收利用中心进行班级旅行。成千上万吨的垃圾被送到那儿。我们将会看见工人们把我们所有的垃圾进行分类以便回收利用。 我认为保护环境是我们的职责。我只是一个人，但是如果我尽了自己的职责，地球就会成为一个更干净、更安全的地方。如果我们每个人为环境做点事情，我们所有人就会有更好的生活。 詹妮

Read the passage and answer the question. 翻译：读短文，回答问题。

'Hazardous' means dangerous. Some hazardous waste is poison — it makes people sick. Some products explode or burn very easily. Hazardous things usually have these labels:'poison', 'caution', 'warning' or 'danger'. What can we do about hazardous waste? Buy less of it! And when you take out the garbage, don't take out your hazardous waste. Hazardous waste in your garbage is bad for the environment. Why? Because we usually bury or burn our garbage. This can make people and the environment sick. Many countries have laws about hazardous waste. The laws don't allow people to bury or burn hazardous waste with other garbage. Many cities in North America keep their hazardous waste in special places. Some have ways to burn it at very high temperatures: from 900 to 1100 degrees centigrade. Hazardous waste is buried two kilometres under the ground in some places. That's deep! 翻译：“Hazardous”的意思是“危险的”。危险废弃物是有毒的——它会让人生病。有些产品很容易爆炸或燃烧。危险物品通常会有这些标签：“有毒的”，“小心”，“警告”或“危险”。对于危险废弃物，我们可以做什么呢？少买它！还有，当你把垃圾拿走时，不要把你的危险废弃物拿走。危险废弃物放在你的垃圾当中是不利于环境的。为什么呢？因为我们通常会埋藏或焚烧垃圾。这可能会让人和环境生病。许多国家都有关于危险废弃物的法律。这些法律不允许人们把危险废弃物与其他的垃圾一起埋藏或焚烧。北美洲的许多城市会把他们的危险废弃物保留在特殊的地方。一些城市有办法在极度高温下将它焚烧：从900到1100摄氏度。危险废弃物被埋藏在某些地方的地下2公里处。那是很深的！
