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. 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. 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 . Operations requiring a vacuum (真空) or extreme cold are examples. Therefore, industrial diamonds might be produced on the moon.
1.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
2.To stay alive on the moon, first of all the early settlers must be able to ______.
A. get enough food, oxygen and water
B. develop commerce
C. make discoveries important
D. explore the possibilities of industrial development
3.Though the environment on the moon is bad for human staying alive, it is very good for ________.
A. all kinds of manufactured goods
B. commercial development
C. making such things as industrial diamonds
D. medical operations

The ocean bottom，a region nearly 2.5 times greater than the total land area of the Earth， is even today largely unexplored. Until about a century ago，the deep-ocean floor was completely inaccessible and hidden beneath waters averaging over 3，600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface，the deep-ocean bottom is a strange environment to humans，in some ways as forbidding and remote as the outer space.
Although researchers have taken samples of deep-ocean rocks for over a century，the first detailed global study of the ocean bottom did not actually start until 1968，with the beginning of the National Science Foundation's Deep Sea Drilling Project ( DSDP). Using techniques first developed for the offshore oil and gas industry，the DSDP's drill ship，the Glomar Challenger，was able to maintain a steady position on the ocean's surface and drill in very deep waters，taking samples of rock from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year-research program that ended in November 1983. During this time，it sailed 600，000 kilometers and took almost
20，000samples of rocks around the world. Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the future. Today，largely on the strength of evidence gathered during the Glomar Challenger's voyages，nearly all earth scientists agree on the theories of plate tectonics (构造学) and continental drift that explains many of the geological processes.
The samples of rocks drilled by the Glomar Challenger have also provided a climatic record stretching back hundreds of millions of years. The information of past climatic changes can be used to predict future climates.
1.The underlined word" inaccessible" in Line 3 means .
A. unrecognizable B. unreachable C. unusable D. unreasonable
2.Why does the author mention "outer space" in the first paragraph?
A.The Earth's climate millions of years ago was similar to that in outer space.
B.It is similar to the ocean floor in being strange to the humans.
C.Rock formations in outer space are similar to those found on the ocean floor.
D.Techniques used by scientists to explore outer space were similar to those used in ocean exploration.
3.Which of the following is TRUE of the Glomar Challenger?
A. It is a type of submarine. B. It is an ongoing project.
C. It has gone on over 100 voyages. D. It made its first DSDP voyage in 1968.
4.The Deep Sea Drilling Project was significant because it was .
A.an attempt to find new sources of oil and gas
B.the first extensive exploration of the ocean bottom
C.made up of geologists from all over the world
D.supported entirely by the gas and oil industry
5.Which is NOT mentioned in the passage as being a result of the Deep Sea Drilling Project?
A.Geologists were able to determine the Earth's appearance millions of years ago.
B.Two geological theories became more widely accepted by scientists.
C.Geologists observed forms of life never before seen.
D.Information was revealed about the Earth's past climatic changes.

In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren’t alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too.
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked “at what age does youth end?”most of these old people had no answer. Several replied, “Well, perhaps at age 80.”
What accounts for this ability to survive to such old age, and to survive so well？First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why？What else would I do？”he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel(血管) system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
1.The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 ____.
A．become weak and hopeless
B．are too old to work in the fields
C．benefit from physical work
D．are still working in the fields
2.What is the main way of life for all of these long-lived people?
A．Retiring from their lives as farmers.
B．Having been married for 90 years.
C．Hard physical work.
D．Having no intentions.
3.Which of the following factors isn’t helpful to people’s health and long life?
A．Clean mountain air. B．Daily hard work.
C． Good genes D． Stress and pressure.

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock. During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House building becomes a great challenge to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.
1.What did people begin to consider as electricity was no longer cheap?
A．The climate of their areas
B．The building materials for their houses
C．The fashions for their houses
D．The energy for their houses
2.People in some areas gain a source of heat by _________.
A．keeping their livestock downstairs
B．protecting their livestock from the cold
C．sharing their houses only with their cows
D．living on the second floor with their livestock
3.The underlined words “natural law” in the third paragraph refer to the fact that ________.
A．heat raises the temperature in the houses
B．heat goes in the upward direction
C．heat goes up if temperature is raised
D．heat increases the temperature of rocks
4.From the passage, we can conclude that _______ .
A．people will no longer consider building materials in the future
B．almost all people will move into the houses heated by large rocks
C．energy-saving buildings will become more popular in the future
D．energy engineers will devote themselves only to modern technology
5.What is the main idea of the passage?
A．Energy-saving house building
B．House building is a great challenge
C．How to live in energy-saving houses
D．Energy-saving houses’ bright future
