例文：Cars and Air Pollution
Too many cars have created a lot of serious problems in our world. Besides congestion，accidents and fast fuel consumption，cars are responsible for a good part of air pollution in big cities. All the time，they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful，causing disease and even death. Last winter，car fumes formed heavy smog over Beijing，making the sky gloomy for weeks and deteriorating people“s health.
One possible solution is to design and develop clean cars and clean fuels. In Tsinghua University，campus buses are driven by electricity. In Beijing some of the public buses begin to run on natural gas，which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones.
Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough，most people will not private cars. And the total number of cars in big cities will reduce greatly. On the whole，the elimination of air pollution needs the co-efforts from the government，the public and the environments. This problem will be solved only with the help of science and technology.
A. Write a letter to your local English-language newpaper giving your view on a discussion that has arisen as a result of an article they published entitled“Why Do We Need English？”
B. Your letter must be writen of about 200 words，excluding the addresses，etc. No.47，Haidian Road Haidian District Beijing，100086 August 18，1999 The Editor Local English Daily Wuhua Building Beijing，100781 Dear Sir：
I have been following with great interest the discussion inspired by Mr Wang Li“s article”Why Do We Need English？“published in the Local English Daily of 20th May，1999.
The one aspect of the English language that most of your correspondents seem to be unaware of is its widespread use as the international language of diplomacy，commerce and technology. It is the language of the United Nations and its agencies as well as of many other international bodies. We would be foolish to confine our vision to our national borders only. We are still，after all，dependent on other countries for technical and industrial assistance. How can we hope to be economically and technologically independent if we are not able to communicate in these areas outside our own country？
English must be taught in all our schools，not only for the above reasons but also so that our students can go abroad to learn the techniques our nation so urgently needs. We also need representatives who can command respect at the international conference tables of the world. And if English is the common language of communications for world diplomacy，economics and defence，then let us be as fluent and proficient in it as possible，for the sake of our own country“s advancement and prestige. Yours sincerely，Li Xiaohua

例文：A Matter of Approach
Two secondary school teahers I remember show how different people can be though engaged in the same profession.
Mrs Wang，my philosophy teacher，sent us to sleep less than ten minutes when she started talking in class. When a head nodded，she would point at the dozing student and made threatening remarks. She said that she was bored teaching us. Some students in her eyes had no desire to learn. But the other teacher Mr Li always had bright eyes in a smiling face and encouraging words which showed that he loved Chinese history he was teaching and wanted us to love it too.
When it came to their attitudes to their students，they were different too. After Mrs Wang finished her day“s lessens she felt that she had finished her job. Once when I asked her a question outside class about a term，she continued with preparation to leave and said that I could bring my question to class next week. Before I knew it she had put her keys into her handbag and walked out of the door. In the history class，however，a question even after the bell would still be given attention to by Mr Li. He would rush to the board in a last minute attempt to clear up. Often he was seen with a number of students standing outside the classroom，discussing the day”s assignment.
Their methods of teaching were not like as well. Mrs Wang stuck to the textbook and trained us how to memorize minute facts. However Mr Li brought in films，maps，slides，tapes，anything that would help us learn. Once the whole class went to see the“film Lin Zexu”in order to better understand the history of the Optium War from 1840 to 1842. Owing to these contrasts，I do not think I can forget either of my past teachers.
