第8题

In the year 2000, the world is going to have a population of about 8 billion. Most scienti

sts agree that the most severe problem is food supply.

Who is going to feed all these people？ Where is the food going to come from？ Are we going to have enough food？ Are we going to produce more artificial foods？

One way of improving the situation is for people to eat less meat. Why？ Because it takes 4 kilos of grain protein (蛋白质) to produce half a kilo of meat protein.Clearly, there is not going to be sufficient meat protein for 8 billion people. Therefore, it will also be necessary to change eating habits because meat is the main part of many people's food today.

A possible solution to this latter problem is the soybean (大豆). The soybean plant produces beans which have a very high fat and protein content. Scientists can now make these look and taste like real meat. They can also make many other artificial products such as soybean milk, for example, which has a taste of milk and can be used in cooking in very much the same ways as cow's milk. In fact, one woman in the United States fed her family only on soybeans for a year! She gave them soybean beef, soybean chicken, soybean mi]k, and sometimes just soybeans. Possibly, we are all going to eat soybeans in the future and finally give up meat completely from our tables.

What is the main subject of the passage？

A．A solution to man's food problem.

B．A solution to the population problem.

C．Advantages of soybean.

D．How to develop good eating habits.

第9题

People all over the world today are beginning to hear and learn more and more about the pr

oblem of pollution. Pollution is caused either by man's release of completely new and often artificial (人造) substances into the environment, or by releasing greatly increased amounts of a natural substance (物质), such as oil from oil tankers into the sea.

Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments Would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed off drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us no only to buy thing we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by curing out unnecessary buying, excess use and careless disposal (处理) of the products we use in our daily lives.

The main cause of pollution is ______.

A．the release of artificial or natural substances into the environment

B．the production of new industrial goods

C．increased amounts of a natural substance

D．our ever-increasing population

第10题

Our environment is getting worse and worse with the increase of the world population, whic

h affects the environment in two ways. Firstly, the limited energy resources will be used up much faster. Secondly, the increasing population creates more pollution, another severe problem that needs to be solved: Both problems are long-term ones because actions taken now show their results slowly over many years. They are also urgent because delays in action can lead to great suffering and social problems. The question seems to be difficult to handle for most people. However, a person can be a protector of environment in everyday life if he takes actions to save the environment right now. With the development of technology, cars make transportation easier and quicker than before, but we can't ignore the disadvantages brought to us by more and more cars in use. For example, we are consuming gasoline(汽油), which is a non-renewable (无法更新的)resource, and will soon be gone. Moreover, the exhausted gas from cars pollutes our air, and our health is therefore threatened by air pollution, which has a big potential effect on our daily life. So we can consider walking, taking buses, carpooling(合用汽车) instead of driving cars alone. This seems to be a very slow process that can't be so effective if it's taken by a single person. But when more and more people become aware of the importance and positively take it as their personal responsibilities, the condition of the air will be improved to a great extent.

According to the writer, the main problem to our environment today is______.

A．the increase of population

B．the limited energy resources

C．the more serious air pollution

D．the development of technology
