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 rally speaking, there are four sorts of waste. They arematerial waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort ofwaste one by rial waste: it means the waste of substance or things from which something else can be made. Forexample, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, theybecome waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, italso becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Onceit is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they areconvenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenienceplastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s truethat rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a longtime and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big nic waste: it refers to waste from living things, including waste from animals, plants and people. Some parts ofvegetables 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 itis called organic ally, we also have inorganic waste, the opposite to organic waste, including building waste,broken pottery and china, and last part is harmful and poisonous waste, such as used batteries, electricalapparatus and medical supplies. Computers and TV sets are one part of electrical apparatus. You see, the old electricalapparatus can set off some dangerous rays and make the soil harder, even damage the under ground water. Mobile phones are asdangerous as computers and TV sets. As we know, X-rays can be used to examine patients, but the X-rays machines are dangerouswhen they are thrown away without any treatment. They can’t be used to treat the sick, but they still can give off rays. Forthe normal people, they can be dangerous. So, we must think about this problem. As waste has four sorts, we can sort theminto each sort that they belong to. It’s convenient to treat them after they are sorted. Then we can deal with them sort bysort. We have thought out some methods like storing them in order to change them into plant food, or burning them in a hugestove and use the heat to make electricity. For the first way, the change rate is much too low and it may pollute the underground water. For the second one, of course it’s wonderful if it’s easy to be tried out. But to build such a huge stovewill cost too much. Not a good method. Now you see, treating waste is not an easy job. 我們生活在世界上每一天。我們吃的食物，飲水，穿衣，看電視，使用計算機等。我們正在製造廢物每rally來說，有四個種類的廢物。他們是材料廢物，有機廢物，無機廢物，有毒和有害廢物。現在，我們談論的每個排序廢物之一rial廢物：它是指物質或廢物的東西別的東西可。爲了例如，人們扔掉用金屬製品，購買一個新的，所以舊的金屬廢料堆積。最後，他們成爲廢物。例如，當人讀完報紙，該文件將成爲廢物。當玻璃被打破，它也成爲廢物。沒有人願意使用一個碎玻璃窗戶破裂，飲品或戴眼鏡的破碎。一次它被打破，就變成廢物。使用塑料率日漸增加。人們使用塑料袋，因爲它們是方便。當他們回家，他們扔塑料的方式，不注重環境。更方便塑料帶給我們更多的塑膠廢料的產生。這就是所謂的“白色污染，因爲大多數是白色的塑料”。我們的產品，我們每天使用的一些橡膠製成，就像輪胎和我們的鞋的底部。這是真的該橡膠了我們生活中的重要作用。然而，它也給我們帶來當它被用於一些麻煩長期時間和變老了。舊的輪胎成爲廢物，因爲它不能破壞自然了。這真是一個很大的問題。有機廢棄物：指廢物生物，包括動物，植物和人的浪費。一些地區蔬菜被丟棄的廢物，因爲他們不好吃。在過去，人們的食物煮熟使用燃煤，所以離開了燃煤，如拋出的蔬菜是沒有用的。所有這些廢物含有各種生物體，因此它被稱爲有機ally，我們也有無機垃圾，有機廢物的對面，包括建築廢料，破碎的陶器和瓷器，以及最後一部分是有害的，有毒的廢物，如廢舊電池，電器，儀器和醫療用品。電腦和電視是一個電器的一部分。你看，舊電器儀器可以引發一些危險射線，使土壤更加努力，甚至破壞地下的水。移動電話是作爲危險的，因爲電腦和電視機。我們知道，X射線可以用來檢查患者，但X光機是危險的當他們扔掉未經任何處理。它們不能被用於治療病人，但他們仍然能發出光芒。爲了正常的人，他們是危險的。因此，我們必須考慮這個問題。由於有四個種類的廢物，我們可以在某種程度上他們到每個排序，他們所屬的。很方便地加以對待後排序。然後我們就可以處理它們排序排序。我們想到了他們一樣存放，以改變成植物性食物，或者在一個巨大的燃燒他們其中一些方法爐竈使用的熱量發電。對於第一種方法，改變率太低，也可能污染下地下水。對於第二個，當然它的美妙，如果很容易就被試用。但是，建立這樣一個巨大的火爐將花費太多。不是好方法。現在你看，處理廢料不是一件容易的工作。#p#分頁標題#e#
