The World is Thirsty for Water
The world is not only hungry, it is also thirsty for water. This may seem strange to you, since nearly 70 percent of the earth's surface is covered with water. But about 97 pement of this huge amount is seawater, or salt water. Man can only drink and use the other 3 percent——the fresh water that comes from rivers, lakes, underground, and other sources.
The amount of fresh water will not be enough for us. First, we cannot use all of the fresh water, because some of it is in the form of icebergs and glaciers, or deep underground. Second, some of it is being polluted. Third, our need for water is increasing rapidly——almost day by day. Only if we take steps to deal with these problems now can we avoid a serious worldwide water shortage in the future.
One of the first steps we should take is to develop ways of reusing water. Today, in most large cities, water is used only once and then discharged into a sewer system. From there it goes to the sea or runs into underground storage tanks. But it is possible to pipe water that has been used to a purifying plant. There it can be used again. Another way is to make use of seawater by removing the salt. This is called desalinization, and it is already in use in many parts of the world.

10. Water Shortage
No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected people’s daily life and hindered the development of the global economy.
A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. What’s worse, pollution and waste of fresh water aggravate the situation.
In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable for us to expect a brighter future.
Air Pollution
Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.
However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
Environmental Protection
Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.
Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.
Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve(保存) our natural resources and recycle(再循环) our products. We are sure that we can have a better and cleaner place in the future.
Direction: For this part you are allowed 30 minutes to write a composition on the to pic Cars and Air Pollution. You should write no less than 120 words and base your com position on the outline below:
1.私家轿车越来越多，有些问题随之产生
2.比较明显的大问题有......
3.我对这种现象的看法
Car and Air Pollution
Too many cars have created a lot of serious problems in our world. Besides co ngestion, 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 t he atmosphere. These gases are very harmful, causing disease and even death.
One possible solution is to design and develop clean cars and clean fuels. In Sh anghai, 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 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 buy private cars. And the total num ber of cars in big cities will reduce greatly.
On the whole, the elimination of air pollution needs the collective efforts from t he government, the public and the environmentalists.
Directions:For this part, you are allowed 30 minutes to write a composition on the topic: Pollution: An Increasing Concern in China You should write at least120 words following the outline below in Chinese.
1. 中国的污染的现状
2. 造成污染的原因
3. 解决的办法
Pollution: An Increasing Concern in China
It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.
Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.
To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. What’s more, the media should play an important role in implanting a sense of environmental consciousness into people’s mind.
If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

1. 绿色校园的重要性，
2. 什么样的校园是绿色的？

On the Importance of Campus Construction
Campus is the place where university students spend most of their daily life through the four-year’s study. Hence, campus construction is of vital importance not only to the physical development of students but to their mental health as well.
Concerning campus construction, it doesn’t exclusively involve green environment
preservation and protection, such as planting more trees and flowers, which makes campus an ecological and natural resort, but advocating green products. For example, students are encouraged to avoid using disposable plastic containers in campus dining hall and recycle wasted batteries and other electrical products properly. In addition to the environmentally friendly practice, we shall make every effort to improve the moral standard and ethical level of university students in order to create a civilized atmosphere for the sake of students’ mental health. For example, students will be severely punished in case of cheating in exams and plagiarizing in academic papers.
As a university student, not only shall we increase our awareness of the importance of green environment in campus but also we take prompt action to purify the campus atmosphere and make it more harmonious.
Creating a Green Campus
In recent years, extravagance and waste have become increasingly serious in some of the university campus. We can see that papers, bottles and cans are thrown away after use; food is wasted just because of its poor taste; clothes are discarded simply owing to their old fashion. As a consequence, people in mounting numbers put great emphasis on creating a green campus.
There are at least two criteria to distinguish what is green campus. On the one hand, natural resources must be conserved and made full use of, for example, we, as college students, should take the wise use of papers and second-hand textbooks into account. On the other hand, education to build up thrift habits must be promoted by relevant departments and professionals at various levels.
Accordingly, it is necessary for us to take effective steps. For one thing, university authorities should respond with the demand for more rigid conservation of our natural resources, such as water, electricity, and so on. For another, we should enhance the awareness of college students that creating a green campus is of utmost significance to both our society and ourselves.
I am the part of the Green Campus
The Olympic Games was hold in our country last year. “Green and Environment-protecting ” is one of the Three Themes of it. Our government has made a great effort in order to protect the environment, build more green project to keep the ecological balance, push the recycling economy, and protects the water resource.
As a university student, we should play an active role in the actions aimed at the realization of green and environment-protecting homeland. We will start it from ourselves, our classmates, our friends and other people around us. We can stop cars running through our campus streets. And in the bathrooms, we will never leave the water running on after using. We will never throw things everywhere without thinking, They are wrong. These things are taking place everyday everywhere in our school. So, let's begin to act! Don't talk loudly in public places. Turn off the water tap after using it. After washing the clothes, use it to flash the toilet.Go to school by bike or by bus instead of by private car. Save your pocket money and contribute to environmental protection organizations. Collect waste paper or bottles for recycling. Plant more trees and flowers.
We can start from every little thing around us to truly realize the green campus. Publicize the theme of green and environment-protecting, and let us really reach the “Green and Environment-prot ecting” goal in our generation. This is the responsibility of everyone who loves life and peace.
To Create Green Campus
Recently, more and more colleges have realized the great importance of creating green campus, and it has become a new trend throughout the whole country.
Then, what does it mean when we refer to green campus? On one hand, the environmental protection is essential and undeniable, which is the premise to this concept. On the other hand, it is far from enough to meet the overall goals of green campus to simply maintain green environment. Instead, it also requires the construction of active cultural atmosphere among all the staff and students by our mutual efforts.
Therefore, in order to create green campus, first, it is necessary that everyone consider themselves as the host of our campus and be aware of the inspirations green house has brought to us. More importantly, actions need to be taken to achieve the aims. Last but not least, we can spread the spirit to a wider area to call upon more people to join this promising project.

一\Limiting The Use of Disposable Plastic Bags
1.一次性塑料袋曾被广泛的使用
2.造成的问题
3.限制使用的意义
Disposable plastic bags were once widely used in China. When we went shopping at supermarkets and departments stores, shopping assistants often provided free plastic bags for our convenience. For a while, life without them seemed unimaginable for most of us.
However, disposable plastic bags do bring severe damage to our environment. Costumers usually threw them away after use, and because they are thin and hard to decompose, these plastic products will exist for a long time. This is an immediate threat to our earth and water. Nowadays, the government has passed relevant regulations for limiting the use of disposable plastic bags: they are not free any more. In some shopping places, in order to invoke the public awareness of environmental protection, plastic bags are offered in a much higher price. As a result, people are changing their behavior: paper and clothing bags that vanished for a long time come back to our daily life. It is true that by limiting its usage, everyone in this society contributes some effort to the improvement of the environment.

•Limiting the Use of Disposal Bags
•These days disposal products often hit the headlines of newspapers and have been brought into focus of the public. Indeed, it is widely accepted that they have gained increasing popularity among people in all walks of life. Taking a look around you, you can find examples too numerous to list: When you walk on the street, you can see plastic bags flying over your head; When you ramble along the river, you can find plastic bottles floating on the water; When you stroll in the park with your lover, you can notice waste paper thrown everywhere.
• Among the most important reasons often cited by people is the quickening pace of modern life. They are often too busy to wash dirty dishes or glasses, as a result they can do nothing but use disposal products. Also playing a part is the improvement of people's life. As a result of the policy of opening and reform, an increasing number of people are much richer than before and can afford disposal products. (原因)
• Admittedly, they might benefit us in a short term. Unfortunately, they will do us harm in more than one way. The major harm is (that) they are sure to pollute the environment. To make matters worse, they are likely to have potential harm to public health. To illustrate this point, I can think of
no better example than HP, the river through S. As a result of disposal products in it, the water has caused some diseases in the local people. (影响)
• To sum up, for the factors mentioned before, we can safely reach the conclusion that the prevalence of disposale products is bound to cause a chain of undesirable effects. In view of the present situation, it is high time that the government tried every means to protect the environment. Only in this way, can we have a bright future.

2. 使用一次性塑料袋带来的问题
3. 限制使用一次性塑料袋的意义
For many years we have been using disposal plastic bags when we are shopping on the market, and most often these bags are offered by the shops for free. This, undoubtedly, has brought us great convenience in our daily life.
However, its disadvantages are also very apparent, and I’ll just venture to explore two aspects. For one thing, the plastic bags are mostly indecomposable in the natural state so that with the increasing use of these bags, it will not only seriously bring about the so-called “white pollution” to the environment, it can also cost us a lot to have them decompose completely so as to minimize their damage to the environment. For another, the production of plastic bags are often not strictly supervised, so a large proportion of the bags don’t meet the requirements for healthy products, which means the more we use them, the more likely we are to suffer in health.
The negative effects of the plastic bags are far serious than w hat I’ve mentioned above, so it’s high time the government issued strict laws and measures to stop using the bags. By so doing, we can save a lot of money from producing these bags as well as return a cleaner earth to ourselves and the later generations.。
