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.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.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 t【英语翻译学习网（enfanyi.com）免费英语学习网站 快速提高英语读说听写能力】hey 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.
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.Actually, we also have inorganic waste, the opposite to organic waste, including building waste,
broken pottery and china, and cinder.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. 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.
我们生活在世界上每一天。我们吃的食物，饮水，穿衣，看电视，
使用计算机等。我们正在制造废物每moment.Generally来说，有四个种类的废物。他们是
材料废物，有机废物，无机废物，有毒和有害废物。现在，我们谈论的每个排序
废物之一one.Material废物：它是指物质或废物的东西别的东西可。为了
例如，人们扔掉用金属制品，购买一个新的，所以旧的金属废料堆积。最后，他们
成为废物。例如，当人读完报纸，该文件将成为废物。当玻璃被打破，它
也成为废物。没有人愿意使用一个碎玻璃窗户破裂，饮品或戴眼镜的破碎。一次
它被打破，就变成废物。使用塑料率日渐增加。人们使用塑料袋，因为它们是
方便。当他们回家，他们扔塑料的方式，不注重环境。更方便
塑料带给我们更多的塑胶废料的产生。这就是所谓的“白色污染，因为大多数是白色的塑料”。
我们的产品，我们每天使用的一些橡胶制成，就像轮胎和我们的鞋的底部。这是真的
该橡胶了我们生活中的重要作用。然而，它也给我们带来当它被用于一些麻烦长期
时间和变老了。旧的轮胎成为废物，因为它不能破坏自然了。这真是一个很大的问题。
有机废弃物：指废物生物，包括动物，植物和人的浪费。一些地区
蔬菜被丢弃的废物，因为他们不好吃。在过去，人们的食物煮熟使用燃煤，
所以离开了燃煤，如抛出的蔬菜是没有用的。所有这些废物含有各种生物体，因此它
被称为有机waste.Actually，我们也有无机垃圾，有机废物的对面，包括建筑废料，
破碎的陶器和瓷器，以及cinder.The最后一部分是有害的，有毒的废物，如废旧电池，电器，
仪器和医疗用品。电脑和电视是一个电器的一部分。你看，旧电器
仪器可以引发一些危险射线，使土壤更加努力，甚至破坏地下的水。移动电话是作为
危险的，因为电脑和电视机。我们知道，X射线可以用来检查患者，但X光机是危险的
当他们扔掉未经任何处理。它们不能被用于治疗病人，但他们仍然能发出光芒。为了
正常的人，他们是危险的。因此，我们必须考虑这个问题。由于有四个种类的废物，我们可以在某种程度上他们
到每个排序，他们所属的。很方便地加以对待后排序。然后我们就可以处理它们排序
排序。我们想到了他们一样存放，以改变成植物性食物，或者在一个巨大的燃烧他们其中一些方法
炉灶使用的热量发电。对于第一种方法，改变率太低，也可能污染下
地下水。对于第二个，当然它的美妙，如果很容易就被试用。但是，建立这样一个巨大的火炉
将花费太多。不是好方法。现在你看，处理废料不是一件容易的工作。#p#分页标题#e#
