题目列表(包括答案和解析)
Will life in the future be better, worse or the same as now? Futurologists(未来学家)predict that life will probably be very different in 2050.
First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms(全息图), which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.
Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.
In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.
In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day.
Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.

In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn’t want to copy the USA’s example. We’re planting more and more trees. We’ve built the " Great Green Wall" of trees across northern part of our country.The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. Great Green Walls will make the world better.

Most earthquakes occur within the upper 15 miles of the earth’s surface, but earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much.
The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set (坚立架), it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir was not strong, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic (地震的) sea waves, or tsunamis (海啸). These are often called tidal waves, but the name is incorrect. They had nothing to do with tides. In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them “tsunamis” meaning “harbor waves”, because they reach a sizable (相当大的) height only in harbors.
Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An earthquake warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground: There is no way to stop the oncoming wave.
【小题1】Which of the following can NOT be concluded from the passage?
| A.The number of earthquakes is closely related to the depth. |
| B.Roughly the same number of earthquakes occur each year. |
| C.Earthquakes are impossible at depths over 460 miles. |
| D.Earthquakes are most likely to occur near the surface. |

| A.their high speed |
| B.the wide shores |
| C.their silent movements |
| D.their long wave length |
| A.help reduce fear |
| B.find ways to stop them |
| C.be warned early enough |
| D.develop warning systems |
| A.two | B.five | C.four | D.three |

The next great land area that man hopes to control is the moon. In size it is nearly equal to the area of North and South America. However, it presents a hostile (不友好的) environment. Temperatures range +120 to -150 degrees Centigrade (摄氏). There is no air, and no water.
Today there is considerable scientific speculation (思索) about living on the moon. When man will begin life on the moon surface is still not determined. But experts believe that settlement will take place in three steps. First, there will be increasing periods of exploration with temporary shelters (临时住所). These periods will be followed by longer stays with housing under the surface of the moon and daily necessities brought by the settlers themselves from the earth. Finally, settlements that are self-supporting will be founded.
The main job of the early settlers will be to stay alive. They will have to plant crops under huge domes (圆顶屋) to produce food and oxygen and find water sources. After this is done, the settlers will have time to explore the possibilities of commercial (商业的) development and to make discoveries important to science. The characteristics of the moon that make it bad for human staying alive may make it ideal for certain kinds of manufacturing (制造业). Operations requiring a vacuum (真空) or extreme cold are examples. Therefore, industrial diamonds might be produced on the moon.
64. The area of the moon is _________.
A. about the same as that of North and South America
B. larger than that of North and South America
C. hardly equal to that of North and South America
D. far smaller than that of North and South America
65. According to this passage, the settlement of the moon ________.
A.will soon be realized
B.can be done under the moon surface
C.is being experimented by many scientists
D. sounds entirely impossible
66. To stay alive on the moon, the early settlers must first of all be able to ________.
A. develop commerce
B. get enough food, oxygen and water
C. make discoveries important
D. explore the possibilities of industrial development
67. Though the environment on the moon is bad for human staying alive, it is very good for ________.
A. making such things as industrial diamonds
B. all kinds of manufactured goods
C. medical operations
D. commercial development
