英语毕业论文《汽车与人类的生活》.doc

Several years ago, a people said: Maybe cars are the worst invention of people. More and more people believe that today. As a matter of fact, we do not know what is happiness and what is we really want about cars. Today, millions of cars run on the earth, we must construct our cities for them, and we walk and follow them with heavy breath. What a shame! We nearly had thrown ourselves under wheels. We must meditate that, and meditate that.1. Cars and our cities.Nowadays, we nearly could not live without cars. The number of cars increased quickly as increase of the number of population. According to the statistic, there are about 24 million mobile cars in China, and 1.2 million of them are home cars. Most of them are in cities, and the number increases by 5 million every year. Experts predicted there will be 60 million cars in China in 2010. Some people said: There only two kinds of animals in cities, one is people, the other is car. The number of cars increased quickly. The city became a sea of cars. Cars share the world with us. In other words, snatch our live space. So more and more people in cities struggle to retake their live space. There are some contradictions between cars and people in cities. I will show them to you. Cars and traffic.The result of cars increase is traffic stoppage, traffic stoppage slows the speed of economic development, and increases the cost of transportation. Consequently, the productivity decreases. The cities will lose their status that had been heartlands and their economy will be broken. For example, the traffic stoppage could decrease the buses efficiency. According to a surrey, if 500 buses in a city decelerated by 1kilometre/hour, it means that this city lost 150 buses transport power. In other words, the government must invest more than 150 buses in public traffic to recover the transport of the city. But if do that, the traffic will be much more harder. And if the cars density increase to 1.5 times, the noise from cars could increase 3 DB. On this condition, the proceeds of cars in China had exceeded RMB 1000 billion yuan. According to the surrey, 90% of roads of Beijing which citys population is 2 million is saturated. 99 big intersections in Beijing are in traffic stoppage every day. Roads are urgent, parking lots are urgent, only cars are not urgent, they are peoples favorites.10 years ago, a sociologist Zheng Ye published his dissertation Criticism of Cars Civilization. He said: Cars did not accelerate traffic speed, but they polluted cities. The parking lots for them ate our parks, the expansion of road for them conquers our theatres, museums and grass. They broke the quiet of suburbs. Cars and environment.Most cars are in big cities, especially in China, so the contaminant in air of these cities is more than the cities in developed countries. Always the energy of cars is petrol Surrey shows that 74% of nitrogen and oxide in air is from cars in London 1990s. It contains CO, CO2, NOx, HC, DM, SO2, and so on. The end gas from cars not only pollute air but also produce more chemical smog to shut our eyes. The HC and NO in the end gas react with each other and release ozone, formaldehyde and peroxide, which is the kingpin of chemical smog. The smog wrap edifices and people breath hardly.The oil which blazes partially in engines releases HC, it contains hydrocarbon, formaldehyde, and so on. It hurts peoples eyes, larynges, and tracheas. Some kinds of compound above are poison and carcinogenic.CO2 is a kind of gas which could result in the moisture of the world increase. It is terrible for circumstances. So 55 countries had signed The treaty of controlling the discharge of CO2 in Tokyo 1997.CO is a kind of produce of engine. A few carbon atoms in the oil oxidize and become CO2 and CO. CO is mild and colorless, it can brook peoples blood system of people, and it is mortal the people whose heart is unhealthy. Excess CO can asphyxiate people, so someone had been killed by CO in the airtight garages or cars.Nitrogen and oxygen react with each other and release their compound. We call it NOx which is the cause of acid rain.Additionally, the lead in oil is a terrorist to health of people.Europe is the birthplace of industrial revolution. The people here had suffered air pollution in 19th century, especially in 1952. Strong smog had wraped all the buildings of London and had stay here for 5 days. 3000-4000people were killed by the smog. I will show some examples of smog disasters.1873, 1150 people were killed by chemical smog in UK.1909, 1000 people were killed by smog in Scotland.1930, 63 people were killed in Meuse.1948, 20 people were killed in the USA.1950, 22 people were killed in Poza Rica.1953, 170-260 people killed in New York.1954, because of smog, hundreds of factories and schools closed up in Los Angeles.1956, 1000 people were killed in London.1962, 750 people were killed in London.1965, 80 people were killed in New York.In western countries, the smog disasters had happened many times. So many people think smog as evil as devil. In China most contaminant is from cars, too. The strength of NOx of air was 18.4% in every city which have a population of 1-2 million in China. It was 20.5% in the cities which have a population of 2 million. In these cities, more and more peoples health is threatened by the air pollution. Some of them love cars, and some of them have cars, but cars hurt them as a bunch of red roses with thorns.Not only the end gas could pollute air but also the process of production could pollute circumstances, the process of oil production could pollute circumstances. In other words, cars are a nightmare of circumstances. The surrey show that the number of people who caught pulmonary disease increased by 5% every year. Most of them are babies and old men. We produced cars, but cars endanger peoples health. The convenience we reaped from the cars is less than we lost. Cars and energy.Cars eat much oil every day as eat our money. Nowadays the price of petrol hurt the people who have cars heavily. Some people predicted petrol will be as expensive as milk. It sound a joke, but it will be a fact soon. In 2002, there were 20.7 million cars in China, the output of oil of China is 160 million ton this year. China had to import 77 million ton oil to feed those cars. Cars eats 87% of all the oil of the world every year. There will be more cars in the future, and more and more oil will be consumed by cars. Only oil will be less and less in the world. Energy crisis will be the present which we give to our next generations.2. Cars and vanity of people.The multiplication of cars number and styles is the root of expansion of peoples vanity. MERCEDES-BENZ, MINI, PORSCHE, HUMMER, KIA, NISSAN, MASERATI, FERRARI, LAMBORGHINI, BENTLEY, AUDI, BMW, GM, TOYOTA, HONDA, FORD, MAYBACH, SPYKER, SAAB, ROVER, RENAULT, MITSUBISHI, LINCOLN and JAGUAR, all the Brands express different status of people who is sitting in the car. Cars become identifications and wealth tallies. In some big cities, many youngsters who go somewhere by bus always feel shame, because they feel they are empty-handed when they stand on the bus station platform. Consequently, more and more people are up to spend their lifetime in saving money to buy cars.Cars are conveyances, but more and more people look them as symbols which indicate wealth and status of people. All the advertisements express that their cars do that above for people. They encourage people to do something to intensify traffic stoppage. Your car can tell you what is your status. Today, cars had become a luxury, as if they are gazing us every minute and every second. If a car is a dream of people, when it comes true, there will be a gray bigger one in your head. 3. Phony cars civilizationThe symbol of the USA became a new industrial country is that its output of cars overtook Europe in 1950. The symbol of Japan became a modern industrial country is that its output of cars overtook the USA in 1970-1980. Cars had become a totem of people, as if a religion. Additionally, Cars hurt our in another way. Wealth was the level of differentiating a person is rich or poor, but cars broken this regulation. Cars announced to people: Yes, you are talented, but I am a car, you can not afford to me! And some cars said: You are wealthy! Yes! But I am a car, I dont want to live with you. Cars gave us new value consciousness and civilization, cars civilization challenges traditional culture to fight. Cars expressed the importance of them for people by their selves logic. Cars quicken peoples lusts and expressed the lusts are logic. It seems only cars civilization has right to give our life a definition. Maybe, several years letter, we will live in the cars civilization completely. We will know that cars arent the culture of people, but people are the culture of cars.Disaster shook peoples hearts. For solving these problems, England government constituted the law of air protection in 1956. German government did that in1959. in 1974, most countries in Europe constituted a united law about air protection which named ECER15 to define the criterion of end gas from cars. Then, the countries in Europe constituted NO2, NO3 and NO4 criterion in1996, 2000 and 2005. This behavior was useful for air protection.At the same time, experts began to invent some apparatuses to decrease the air pollution from cars. For example, they installed HCTS and EGR which are new apparatuses can make oil burn plenty in engines. So that cars will release less CO and HC into the air.And some experts believe that the cars with mixed energy will be a project to solve the crisis of energy. Electricity, oil, gas and alcohol will be the energy of cars. It is convenient and good for environment. The TOYOTA company had invent the first mixed energy car named Prius in 1997. The releasing amount of CO2 of it is only 104g/km. This technology is not very executable, but I think the dream of environment protection of people will come true one day. The air around us will be disinfected one day. When we want to use cars to accelerate our speed, we must know that Zhu Chongzhi discovered circumference without computers, architects built Tian An Men without the CAD software, and Xu Xiake went around China without cars. You see this, people can do many things well without those machines. I dont want to encourage people to cycle anywhere, I only want to encourage people to search your rational thinking. Cars are not wrong, only the attitude of us for cars is wrong. From the above, we know some people had woken from trance, they began to concern our cities and environment. I hope, more and more people will join us and do something to protect our live space. God created human, people created cars, we change our health for speed, it is a joke and it is stupid. More and more people hate living with these glacial machines. Wh
