環境保護environment protection 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 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. 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.
I don't know that too.
Either i don't know that.
I don't know that, either.
Neither i know that.
neither do i.
對，你說的集中表達方式都是我不知道的意思。 i don't kown . i have no idea.幾乎可以互相替換。 i don't know/have no idea what you are talking about. 我不知道你在說些什么。 還有： i am not quite sure it's above me it's hard to say. you got me. 這些也都是我不知道，你難倒我了 的意思。
