1989年1月六级作文题及范文

Directions: The Problem of Human Population 范文： It has been estimated that a thousand years ago there were less than 400 million people on earth. However, in the recent thousand years human population has increased nearly 20 times. Nowadays the world population has reached more than 7000 million. The population explosion has caused many problems. Generally, they come down to four major ones. First, a lot of people can't get employment, which is a universal problem in the world. Second, in developing countries there are not enough shelters for too many people and so people are not properly housed and even are exposed to the elements. Third, in underdeveloped countries a lot of people suffer from hunger because of food shortage, which in turn causes many other problems, malnutrition, disease, etc. Fourth, there are not enough schools for so many people and so a lot of people are illiterate. Therefore, to eliminate these problems, human beings should take effective measures to control population. 1990年1月六级作文题及范文

Directions: 问题：城市交通拥护解决方案：（solution） 1. 建造（lay down）更多道路 优点：降低街道拥护程度加速车流（flow of traffic） 缺点：占地过多 2.开辟（open up）更多公共汽车线路 优点：减少自行车与小汽车 缺点：对部分人可能造成不方便 结论：两者结合 How to Solve the Problem of Heavy Traffic

范文： The urban traffic is getting increasingly crowded nowadays in China. The roads are pakced with cars, bicylces and pedestrians and traffic jams, bus delays and traffic accidents are a common scene. Then how to solve this problem? Some suggest to lay down more roads to make the traffic less crowded and speed up the flow of traffic. Others believe that we should open up more public bus routes, so that more people will take the public buses instead of travelling by cars and bicycles. Though above two views sound reasonable, they have their own drawbacks. The fomer may take up much land which could be used for farms and houses. The latter may cause inconvenience for those who are used to travelling by car or bicycles. I think the best answer to the traffic problem is a combination of the two. More roads can be built to hold more traffic and meanwhile more public bus routes can be opened up to those who prefer to use the public transportation. 1990年6月六级作文题及范文

Though the government has spent a large sum of money on housing, the investment has produced little financial return and a housing shortage still persists. Two generations sharing one room and newly-married couples finding it difficult to have a house of their own are still common cases. Housing shortage is a problem that requires and urgent solution.

People's attitudes towards the solution to the housing problem are different. Some suggest to build more high-rise apartmentsothers believe to develop underground housing areas. I am in favour of the former opinion. For one thing, it is cheaper to build above gound than below. For another, living underground for a long time will do harm to people's health. Above all, people are unwilling to live unerground with artificial lighting and they prefer to live above ground to enjoy the sunshine. Although there may be some other ways to solve the housing shortage problem, I believe to build more high-rise apartments is one of the promising solutions to the housing problem.

Besides, scientists are making a thorough study of genes and they will manage to cure cancer by adjusting the arrangement of genes. They are also making efforts to control pollution and population. Furthermore, all the governments in the world are concerned about these problems and they have taken measures to solve these problems. Therefore, we have every reason to be sure that human beings will conquer nature but they will never be conquered.

范文： The graph shows the changing rate of car accidents in Walton city in 1990. The first two months of 1990 showed an increasing trend. The rate rose to 32 in March but fell to 26 in June. From June on the rate was rising again and reached the peak point 39 in August. After August the rate began to decline, and eventually dropped to the lowest point 16 at the end of the year.

The highest rate in August was due to unfavorable weather conditions. Humidity and high temperature make drivers impatient, which easily leads to car accidents. The high rate in the first half of 1990 was also caused by the bad weather condition. In Walton City the excessive rain comes at early spring. The rain made road slippery, which often resulted in car accidents. This year the pattern is expected to change. The city government has raised fund to improve the road condition. Two new roads will be finished at the beginning of this year and are expected to open to traffic soon. Furthermore, the new road regulation provides that in summer every car must be air-conditioned. With all these precautions, I'm sure that the rate of car accidents will be much lower this year.

Film Is Giving Way to TV

范文：

Nowadays there are fewer and fewer cinema-goers and the cinema is slack. However, there are more and more TV viewers. There are many reasons for this social phenomenon, but in general, they come down to three major ones.

First, film tickets are too expensive, while it doesn't cost much to watch TV at home. Besides, it is time-consuming and inconvenient to go to the cinema. Nevertheless, it is very convenient and comfortable to watch TV at home. You needn't go out but just need to turn on the television. Most important of all, if you don't like the film you'll have to sit through itbut if you don't like one programme on TV, you can shift to another.

However, some people still go to the cinema. They usually go to the cinema for the purpose of social contact. Young people go dating there. Other people go to the cinema as an activity. For example, schools often organize children to go to the cinema. Sometimes employees also go to the cinema with the film tickets presented by their institutions.

Looking Forward to the Twenty-first Century

范文：

The new century is approaching. It can be expected that there will be a breakthrough in life sceience and space science in the 21st century.

First, scientists will conquer incurable diseases through the transformation of genes. With the same technology they can breed new species of animals and even human life in the laboratory. Most important of all, they can decelerate aging and prolong life.

Besides, permanent stations will be set up in the moon or other planets or stars so that scientists can make a thorough study of the moon and other planets or star. Most probably life will be found in other stars in universe or the planets or stars suitable for the human existence will be discovered.

However, the scientific development will also bring about some social problems. How should we regard from an ethical perspective the one who is bred through the gene technology in the laboratory. How can the police identify the criminal from a group of people with the same DNA?

It is quite natural that we will meet problems in the scientific and social development. Therefore, we should be prepared to meet new challenges.

范文：

Nowadays, motorcycles are popular around us. They have be come an important means of transport in Chinese cities. Compared with the bike and the car, the motorcycle has its own advantages.

First, it is quite flexible. When there is a traffic jam, it can go through the cars that are held up in the street. Besides, it doesn't consume much petrol. Most important of all, it can carry another person at the back.

But every coin has two sides. The negative aspects are also apparent. To begin with, it's very complicated to get qualified for riding a motorcycle. You'll have to go through a series of procedures to get a riding license. Furthermore, the maintenance is expensive. Worst of all, it costs a big sum of money to pay for the license plate, especially in Shanghai.

In conclusion, it has both favorable and unfavorable aspects. However, if the authorities concerned simplify the procedures and reduce the cost of the license plate, the motorcycle will be accepted by more people.

Directions: For this part, you are allowed 30 minutes to write a composition on topic My View on Opportunity. You must base your composition on the following instructions (given in Chinese):

有些人认为机会是极少的，另一些人则认为人人都有某种机会。你的看法如何？写出你的观点，说明你的理由并举例。在你的文章结尾处不要忘记写出你的结论。

范文：

Different people have different views on opportunity. It is held that there are few opportunities. But it is also held that there re opportunities everywhere.

Those who hold the first opinion think that there are too many people and so there is always an intense competition for limited opportunities. In contrast, those who hold the second view think that if one is not prepared, he can hardly have any opportunitieshowever, if one is prepared, he can have a lot of opportunities.

As to me, I agtee with the latter opinion. Admittedly, there is really an intense competition for limited opportunities, but this is not to say that one can't create opportunities himself. In most cases opportunities are created by people themselves. For example, many people lost their jobs in recent years. Some people wait for opportunities in vain. However, others create opportunities themselves and get self-employed. Eventually they become employers themselves.

Therefore, to some extent, one can take his destiny into his own hands.

We Need to Broaden Our Knowledge

范文：

Knowledge is power, especially scientific and technological knowledge. Science and technology are the motive power of the social development. Without them human society could never have developed from primitive society to modern society. Therefore, to conquer and transform nature, we must master scientific knowledge.

However, social knowledge is also essential. Without it we can not understand society and don't know the law of the social development. As a result we are unable to govern society. Therefore, besides scientific knowledge we need to master social science, philosophy, politics, history, aesthetics, etc, so that we can know society from all perspectives and form a correct world outlook.

To meet new challenges in he 21st century, we university students should lose no time to acquire as much knowledge as possible so that we will become qualified successors of the socialist cause.

The Career I Pursue

范文：

In China young people usually want to be engineers, doctors, businessmen, etc. and few want to be teachers. Unlike most young people I decide to be a teacher. There are many reasons for my personal preference but generally they come down to three major ones.

First, I was born in a teacher's family and so I was greatly influenced by my father. Second, I find that education is important because it is the basis of science and technology and if a country's education is backward, its science and technology will never be advanced. Third, teachers are needed in our country, especially in the countryside.

However, it is not easy to be a qualified teacher. A qualified teacher must have a good command of his specialty. Besides, he should be responsible and devoted to the educational cause. Most important of all, he should be patriotic. To be a qualified teacher in the future I must lose no time to acquire as much knowledge as possible. 'Furthermore I must know the history of our country so as to cultivate patriotism.

范文：

Nowadays ther are a lot of false advertisements in society. They have caused many harms to society. Generally, their harms can be listed as follows.

First, they exaggerate the functions of the goods they advertise and mislead consumers. Second , some advertisements contain obscene contents and bring about spiritual pollution. Third, they seriously damage the credit of businesses because the shops which sell those goods will be distrusted and even considered the conspirators of those advertisers by consumers.

Personally, I am usually vigilant against any advertisements and so I have never been taken in. However, some people are credulous and are easily taken in. Therefore, in my opinion, effective measures must be taken to ban false advertisements and protect consumers' interests. First, all the advertisements must be strictly censored by the authorities concerned before they are published. Besides, severe unishment must be inflicted on those who publish illegal advertisements.

In conclusion, false advertisements must be eliminated in our society.

Different people have different views on firecrackers. Some people think that firecrackers should be banned because they endanger people's lives and social security. However, others hold that firecrackers houldn't be banned because they will drive evil spirits and bring luck.

As to me, I am in favor of the first idea. The reasons are as follows. First, addmittedly, letting off firecrackers will create an auspicious atmosphere, but it will not really bring luck to let off firecrackers. Besides, it is dangerous to let off firecrackers. It was reported that letting off firecrackers causes a lot of accidents, fire, injury, and even death every year.

However,it is our traditional custom to celebrate an important occasion by letting off firecrackers.How can we let off firecrackers whithoug causing accidents? The possible solution is that the substitute for the firecracker should be invented so that we can celebrate an important occasion whitout causing accidents.
