Fewer cars, better lifeBeijing No. 71 Middle School Guo YanhuiFirst, lets look at the blackboard and find out what this is. (Draw a car). Yes, its a car. Please raise your hand if you have a car. Please raise your hand if you want to buy a car.Its true that having a car is convenient. My husband and I have a debate about whether buy a car or not. My home is far away from our working place which will take us about 50 minutes to get there. So he wants to buy a car. I want to go by bus because I think 50 minutes is OK if we get up earlier. We can save money. Its also safe and trouble free since the bus drivers are well trained. They are skillful and careful. He thought the child will suffer by taking bus or subway. However, I think maybe sometimes he/she will suffer. Everyone cant feel sweet without tasting some bitterness. Based on our different opinions, I choose this topic. And after thinking it over, I think its really valuable to share it with all of you.(Show picture 1traffic jam) You can see all the cars rush and just look like a very long dragon. Its traffic jam. Now it not only happens in the rush hour. Look at the pipe on the car. They are rubbish gas. One car may produce a little. How about hundreds of or thousands of cars everyday? Its pollution. Besides,. The price of the fuel or gasoline is rising because it cant be reproduced and its necessary in daily life and industry of China. (Show picture 2-the earth) We only have one earth and one hometown. We should try to make it better.Here my opinion comes:If you have a car, drive as little as you can. Please only drive when you think its necessary. Try to use other transportation more. Please affect others by your action. If you havent got a car, please dont buy unless its really necessary. For example, it you want to go from place A to B, taking bus20 minutes, driving a car5 minutes. If you are not in a hurry, please go by bus.Ill explain more about why we should do this.The first reason is pollution.We all know that pollution is quite serious in China now, especially in big cities like Beijing. You may say, “there are lots of reasons for pollution, such as heavy industry.” Thats true. We can do little to that. But we really can do something to reduce pollution from cars. You know every car has a pipe to get rid of rubbish gas. Suppose one car in one day will get rid of as much rubbish gas as the air in a ball. For 2 cars, two balls. How about hundreds or thousands of cars? How about for a year? How huge it will be! Although the earth-our mother-has the function to clear itself up, it cant suffer too much.I get the news from newspaper-“cancer, stoke, top killers for Chinese.” And in the city, cancer is the first killer. Can you guess which cancer is the top 1 killer in cancers family? Yes, lung cancer. Now in TIP, we do an exercise in the morning everydaybreathe in English, breath out English. We feel fun to do that. But in the city, when we take a deep breathe, we breathe in polluted air with harmful items in it and we breathe out the polluted air but with some harmful things left inside us. Everyday we do this “breathe in and breathe out” thousands of times.I want to explain more about the rubbish gas. It contains CO, HC, PD and more harmful items. For CO, when we drive the car, the fuel or gasoline in it will fire. One kilogram of fuel or gasoline will spend 15 kilograms of fresh air (15kg) and produce 150-200 grams (150-200) CO. Its like this: Fuel or gasoline Fresh air CO 1kg + 15kg = 150-200g + CO is a kind of item which you cant smell it or taste it out. You cant feel it, but it exists. It can stay in the air for 2-3 years. You may ask how harmful it can be. Imagine, this is a stere with 4g CO in it. The person in it will die in 30 minutes. Besides, CO also can affect babies and make the baby have low IQ or be disabled. Of course its also harmful for old people and all of us. How terrible it is! So sometimes, Im wondering maybe our human beings will kill ourselves at last if we dont take actions. Then remember, drive less, less pollution.The second reason is because of this (show picture1)traffic jam. Have you suffered this before? Whats your feeling? In these years, the number of cars grows rapidly. We want to buy a car just because we want to be convenient. But we have fewer roads compared to the increase of car numbers, so every day traffic jam happens. Its really a suffering. Various kinds of cars move slowly or even cant move for a long time. Everyone wants to be convenient, but actually no one can be. The problem will get even worse if everyone tries to drive more and buy more cars. Fortunately, our government makes the price for taking bus 4 jiao 10 kilometers and 2 yuan for subway. Its cheaper and even faster. Its really convenient. If more and more people are willing to take the bus, subway or the ways, the traffic jam certainly can be less and less. Then everybody can be really convenient. Well. You may think,”I know the problem is serious. But if I dont drive or drive little, the traffic jam and pollution will not disappear.” Thats true. But what if everyone thinks in this way? For example, our city is much cleaner because most of us know we shouldnt drop litter on the street. Maybe from very beginning, little people care. Our city is dirty at that time. Then gradually, we all care about that. Now our children are also affected by us. They dont drop litter, either. The people affect each other. The same will happen on the car issue. Today one of you learns that Id better drive little. Then when you stay with your family members or friends, you can affect them by your action or words. Most of us are teachers, so we also can affect our students. Suppose one of you affect 2, then they affect 4, gradually, the change will be great. Maybe I can make it clearer by an example. Once a wise man won a prize from a king. Then the king asked what he wanted. The wise man drew a square with 100 small boxes in it and said,” Please put 1 grain of rice in the first box, then 4 in second 2 grains of rice, the third one 4, the fourth one 16, the fifth one 256 ” The king was very happy at first, but later he found he had to give all the rice in his country to the wise man. You are like a grain of rice, you affect 2, 2 affect 4, 4 affect 8, 8 affect 16. Then gradually the change in our society will be huge. So believe yourself. Every one of us can make a change to the
