We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.
我们每天都生活在这个世界上。我们吃东西，喝水，穿衣服，看电视，用电脑等等。我们每时每刻都在产生废物。
Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one.
一般来说，有四种废物。它们是物质废物、有机废物、无机废物和有毒有害废物。现在，我们将逐一讨论每一种废物。
Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It's true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it can't break down by nature. This is really a big problem.
物质废物：它指的是物质的废物或可以制造其他东西的东西的废物。例如，人们扔掉旧的金属制品，买一个新的，所以旧的金属废料堆积起来。最后，它们变成了废物。例如，当人们看完报纸，报纸就会变成废物。玻璃碎了，也就成了废物。没有人想用破窗户，或者用碎玻璃喝酒，或者戴一副碎玻璃。一旦被打破，就变成了废物。塑料的使用率日益提高。人们使用塑料袋是因为它们很方便。当他们回到家，他们扔塑料的方式，不注意环境。塑料给我们带来的便利越多，产生的塑料垃圾就越多。这叫做“白色污染”，因为大多数塑料都是白色的。我们每天使用的一些产品是由橡胶制成的，就像轮胎和鞋子的底部一样。的确，橡胶在我们的生活中起着重要的作用。但是，它在长期使用和老化的同时，也给我们带来了一些麻烦。旧轮胎因其不会自然损坏而成为废物。这真是一个大问题。
Organic waste: it refers to waste from living things, including waste from animals, plants and people. Some parts of vegetables are thrown away as waste because they don't taste good. In the past, people cooked their food using burning coal, so there left the burned coal, which is useless, like the thrown vegetables. All this sorts of waste contain organism, so it is called organic waste.
有机废物：指来自生物的废物，包括来自动物、植物和人类的废物。有些蔬菜因味道不好而被当作废物扔掉。在过去，人们用燃烧的煤做饭，所以留下了燃烧的煤，这是无用的，像扔蔬菜。所有这些废物都含有有机物，所以被称为有机废物。
Actually, we also have inorganic waste, the opposite to organic waste, including building waste, broken pottery and china, and cinder.
实际上，我们也有无机废物，与有机废物相反，包括建筑废物、陶器碎片和瓷器，以及炉渣。
The last part is harmful and poisonous waste, such as used batteries, electrical apparatus and medical supplies. Computers and TV sets are one part of electrical apparatus. You see, the old electrical apparatus can set off some dangerous rays and make the soil harder, even damage the under ground water. Mobile phones are as dangerous as computers and TV sets. As we know, X-rays can be used to examine patients, but the X-rays machines are dangerous when they are thrown away without any treatment. They can't be used to treat the sick, but they still can give off rays. For the normal people, they can be dangerous. So, we must think about this problem.
最后一部分是有害和有毒的废物，如废旧电池、电器和医疗用品。电脑和电视机是电器的一部分。你看，旧的电器会发出一些危险的射线，使土壤变硬，甚至损坏地下水。手机和电脑、电视机一样危险。我们知道，X射线可以用来检查病人，但是X射线机在没有任何治疗的情况下被扔掉是危险的。它们不能用来治疗病人，但仍能发出射线。对普通人来说，他们是危险的。所以，我们必须考虑这个问题。
As waste has four sorts, we can sort them into each sort that they belong to. It's convenient to treat them after they are sorted. Then we can deal with them sort by sort. We have thought out some methods like storing them in order to change them into plant food, or burning them in a huge stove and use the heat to make electricity. For the first way, the change rate is much too low and it may pollute the under ground water. For the second one, of course it's wonderful if it's easy to be tried out. But to build such a huge stove will cost too much. Not a good method. Now you see, treating waste is not an easy job.
由于废物有四种，我们可以把它们分为属于它们的每一种。把它们分类后处理是很方便的。然后我们就可以一点一点地处理它们。我们已经想出了一些方法，比如把它们储存起来，以便把它们变成植物性食物，或者把它们放在一个巨大的炉子里燃烧，然后利用热量发电。第一种方式，变化率太低，可能污染地下水。对于第二个，当然，如果很容易尝试的话，那就太好了。但是建这么大的炉子要花很多钱。不是个好方法。现在你明白了，处理废物不是一件容易的事。
From what has been discussed above, we can do something to our home—the earth. We should make full use of things. At the same time, we'd better reduce its harmful effect as much as possible.
根据上面讨论的，我们可以对我们的家园地球做些什么。我们应该充分利用一切。同时，我们最好尽可能减少它的有害影响。
We can do from the basic of waste. That's to say, we can reduce the production of waste, and reuse and recycle them as much as we can. Take material waste for example. Nearly all of them can be recycled and reused. And, we should call for using things made of paper instead of plastics so as to protect our environment.
我们可以从废物的基础上做。也就是说，我们可以减少废物的产生，并尽可能地重复利用和再循环。以材料浪费为例。几乎所有这些都可以回收再利用。为了保护我们的环境，我们应该呼吁使用纸制品而不是塑料制品。
Protecting the environment is not one person's duty; it depends on all of us. What can we do? Maybe a dozen..
保护环境不是一个人的责任，这取决于我们所有人。我们能做什么？也许一打……
In a word, use what can reuse as much as possible. Remember, environment protection is not one's duty!
一句话，尽可能多地使用可以重复使用的东西。记住，环境保护不是我们的职责！
