Life in 2060

  Let us suppose it is now about A.D. 2060. Let’s make believe (假装;虚构) it is about sixty years from now. Of course, things have changed and life is very different.

  Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment (娱乐) of young and old.

  What are people eating now? People are still eating food. They haven’t yet started to take on heir (继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.

  Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.

  Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.

  People are now largely vegetarians (素食者). You see, as the number of people increases, the number of animal decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.

  Such would be our life in 2060.

The sea has always interested man. From it he can get food, minerals, and treasure.    1   But he could not go far beneath its surface.

    2   However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

  A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases.   3   He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea.   4  

When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜水夫病). The bends can cause a diver to double up in pain.    5  

A.His body is under great pressure.

B.Scientists are trying to find more about the sea.

C.For thousands of years, he could sail on it.

D.They can even kill him.

E. He can wear a diving suit and have air pumped to him from above.

F. The water pressure can cause a diver to breathe with difficulty.

G. Man wants to explore deep into the sea.

  Trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought and floods.

  Unfortunately, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.

  Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

  Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

  This does not only mean that the villagers? sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.

63. The purpose that the writer wrote this article for is ____ .

 A. to tell people that trees are very useful to man

 B. to warn people not to cut down trees any more

 C. to warn that man mustn't destroy forests any more

 D. to explain how trees help to prevent drought and floods

64. In the writer's opinion, ____ , or the forests slowly disappear.

 A. measure must be taken                      B. people shouldn't draw benefit from the tree

 C. government must realize the serious results      D. unless trees never be cut down

65. According to the article we know it is ____ to prevent the forests from slowly disappearing.

 A. necessary but impossible                    B. necessary but difficult

 C. impossible and unimportant                  D. difficult and impossible

66. In the last two paragraphs the writer wanted to make it clear that ____ .

 A. where there are no trees, the soil becomes hard and poor

 B. where there are many trees, there are fewer floods

 C. where there are no trees, the land might become desert slowly

 D. floods will make the land become desert

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

  Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

  For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

 

1.The author’s attitude towards the use of natural resources is _________.

    A. positive         B. uninterested     C. optimistic           D. critical

2.According to the author, the greatest mistake of our forefathers was that _________.

  A. they had no idea about scientific forestry

  B. they had little or no sense of environmental protection

  C. they were not aware of the importance of nature study

  D. they had no idea of how to make good use of raw materials

3.To avoid repeating the mistakes of our forefathers, the author suggests that _________.

  A. we plant more trees

  B. natural sciences be taught to everybody

  C. environmental education be directed toward everyone

  D. we return to nature

4.How can you understand the underlined sentence in the last paragraph?

A. Our living space on the earth is getting smaller and smaller.

B. Our living space should be measured in cubic volume.

C. We need to take some measures to protect space.

D. We must preserve good living conditions for both birds and animals.
