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, malnutrition2, disease, etc. Fourth, there are not enough schools for so many people and so a lot of people are illiterate3. Therefore, to eliminate these problems, human beings should take effective measures to control population.
范文: The urban traffic is getting increasingly crowded nowadays in China. The roads are pakced with cars, bicylces and pedestrians4 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.
范文: The shortage of housing is one of the most serious problems facing many big citeis in China. 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 apartments; others 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 unwilling5 to live unerground with artificial lighting6 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 promising7 solutions to the housing problem.
范文: Nowadays humanity is faced with a lot of troublesome problems: energy crisis, cancer, pollution, population explosion, etc. They are threatening the survival of humanity. Therefore, some people are pessimistic about the future of humanity. They are pessimistic because they think that limited energy on earth will be exhausted8 soon; incurable9 diseases are threatening more people's lives; pollution is worsening the environment; population explosion will make food shortage even more serious. Actually they needn't worry too much about these problems. Scientists will have developed new energy resources by the time oil and coal are used up. Besides, scientists are making a thorough study of genes10 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.
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 inconvenient11 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 it; but 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.
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 transformation12 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 ethical13 perspective the one who is bred through the gene1 technology in the laboratory. How can the police identify the criminal from a group of people with the same DNA14? 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 qualified15 for riding a motorcycle. You'll have to go through a series of procedures to get a riding license16. 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.
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 opportunities; however, 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.
