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 go羊角风主要表现od. 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.
(There are too many cars in our streets)
Today, most people in the city rely on automobiles as a means of transportation. While many people still take t癫痫怎么检查出来he city buses, more and more are driving to work every in their own cars. To many city dwellers, cars have become a necessity. But too many cars in the street also create problems. Traffic congestions, accidents and air pollution are the three most obvious problems that accompany a sharp increase of cars.
We often get caught in heavy traffic during the rush hours, when it takes a long time to move forward even an inch. And thousands of people die while a greater number are injured, some crippled for life, in traffic accidents every year. If we want to enjoy our cars in safety, we had better follow the traffic rules carefully.
谈谈你的看法(Week-long Holidays,Good or Bad?What
Our National Day is coming. We shall have days of rest,presumably weeklong holidays again just like the weeklong May Day holidays. Many people welcome weeklong holidays and are busy planning where and how to spend the seven days;whereas many other people do not applaud.
As to me, weeklong holidays mean a span of dullness, boredom, melancholy and helplessness, and I think anyone who had experienced the holiday sufferings in May would share my feelings. I well remember that from May Day, to be more exact, a few days earlier than May Day, the shopping season started.Most shops extended their shopping hours to respond to their overwhelmingly enthusiastic customers. There were special sales with discount coupons and instant lucky draws and various sales promotions in nearly every big store to lure po tential customers into spending more. Crowds of shoppers flocked towards department stores, enjoying their high purchasing power. There were traffic jams almost everywhere, people waited in long queues at bus-stops:and taxi-stands? looking entirely exhausted.Tempers flared when people gotpushed or if some儿童癫痫病怎样治疗one else cut the queue.Impatient drivers honked at each other every now and then. The railway station was congested with travelers who rushed to the platform like a swarm of bees and then squeezed their way into the train for seats as if there would be no tomorrow. In the restaurants, tables were shared. A platoon of waiters filed out from the kitchen armed with various containers of eatables. Orders were taken feverishly and then shouted across to the kitchen. Excitement reigned everywhere as waiters ran hither and thither to fill the orders. The above are just some vivid scenes that happened a few months ago.
Everywhere was chaos and chaos everywhere. I am really afraid the drama will soon be repeated. True,weeklong holidays help activate economy, but what about after-holiday depression? No doubt, people can have a lot of leisure, but leisure does not always bring a lot of pleasure.
(The Function of Humor)
Humor has become one of the most attractive characteristics a successful person must have nowadays, not only because it can bring laughter and happiness to people, but also because it shows a man‘s a bility.
A little joke can easily remove an unpleasant conflict, change the talking atmosphere and make it harmonious. Under such circum stances, businessmen can make a big deal and politicians can sign an agreement, which are good bases for future cooperation.Some humor enables people to feel bitterness from laughs, which we call "cold humor" or "black humor". At this time, humor is like a sharp sword, which may pierce people‘s heart. People may wipe sadtears after laughing and contemplate after the shock given by the story. It often appears in movies and novels.
Humor plays a great role on some important occasions, when a person, especially a gre杭州哪里看癫痫病好at one, is judged from such a capacity. It can help leaders to point out. shortcomings or wrong behavior of his subordinates, without letting them feel embarrassed. So sometimes we also regard it as a certain kind of art. Humor is important in everyone‘s life, whoever he is. Because you can deal with all kinds of embarrassing occaslon with this special skill. Why not enrich your knowledge and become a man with a good sense of humor?
Generation gapGeneration gap refers to the distance and contradiction(矛盾) between the old and the youth.
It’s a common(常见的) phenomenon(现象) that exits everywhere in the world and influences both the old and the youth.Generally speaking, generation gap results in different understanding and appreciation of the great and constant(固定的) changes of the world, different reaction to new things, and different attitudes to tradition(传统) principles(原则) and beliefs. Therefore, we may say where there are the old and the youth; there is the generation gap.
Generation gap is natural, but very influential(有影响的). If we cannot deal with it appropriately(适当地), the gap will be greater and the greater and consequently(结果) affect the work and the relation between the old and the young.
