The reason for believing that future man will be different is that he_______.
A is always
B hopes for a change
C never stops changing
D will live a different life
About 2000 years ago, the world 24 was probably about 250 million.It reached a billion in 1850.By 1930 the population was two billion.It is 25 three and a half billion.It is expected to double by the year 2000.If the population continues to grow at the same 26 , there would be 25 billion people in the world a hundred years from now.
Man has been using the earth’s 27 more and more rapidly over the years.Some of them are almost gone.Now many people believe that man’s greatest 28 is how to control the growth of this population.The materials in the world will not support the human population in time to come if the present rate of increase continues.29 there is over crowding in the cities and hunger in some countries.Can man’s rate of increase continue？
Many people believe that human survival (幸存者) in the future 30 on the answer to the question.

In ancient times, man settled near rivers or on fiver banks and built up large empires.
Water is Nature’s most precious gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world rivers mean life and wealth. They feed and clothe the nations around them.
Water is also a source of energy and power. Man constructs huge dams across the river to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.
Man uses water each day. His main source of water comes from reservoirs, which in turn get their water from the rivers.
Rivers also bring down soil and minerals from the mountains and deposit them on the plains building up rich fiver deltas for raising plants and crops. Fresh water life in rivers or in lakes fed by them provide man with food.
In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.
Rivers have run on this earth long before man. Man’s future ability to live is uncertain, but rivers will flow on forever.
Rivers have been important to man ______.
A．since the last century
B．for a very long time
C．since a few hundred years ago
D．since a few years ago

How can we get rid of garbage (垃圾) ？ Do we have enough energy sources to meet our future energy needs？
These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.
For a long time, people buried garbage or dumped (倾倒) it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas, but they are chemically similar to these fossil(化石) fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source.
Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.
Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.
What two problems can man solve by burning garbage？
A．The shortage of energy and air pollution.
B．The shortage of energy and the land to hold garbage.
C．Air pollution and the shortage of fossil fuel.
D．Air pollution and the shortage of land to hold garbage.
I believe in people, in sheer, unadulterated humanity. I believe in listening to what people have to say, in helping them to achieve the things which they want and the things which they need. Naturally, there are people who behave like beasts, who kill, who cheat, who lie and who destroy. But without a belief in man and a faith in his possibilities for the future, there can be no hope for the future, but only bitterness that the past has gone. I believe we must, each of us, make a philosophy by which we can live. There are people who make a philosophy out of believing in nothing. They say there is no truth, that goodness is simply cleverness in disguising your own selfishness. They say that life is simply the short gap in between an unpleasant birth and an inevitable death. There are others who say that man is born into evil and sinfulness and that life is a process of purification through suffering and that death is the reward for having suffered.
I believe these philosophies are false. The most important thing in life is the way it is lived, and there is no such thing as an abstract happiness, an abstract goodness or morality, or an abstract anything, except in terms of the person who believes and who acts. There is only the single human being who lives and who, through every moment of his own personal living experience, is being happy or unhappy, noble or base, wise or unwise, or simply existing.
The question is: How can these individual moments of human experience be filled with the richness of a philosophy which can sustain the individual in his own life？ Unless we give part of ourselves away, unless we can live with other people and understand them and help them, we are missing the most essential part of our own human lives.
There are as many roads to the attainment of wisdom and goodness as there are people who undertake to walk them. There are as many solid truths on which we can stand as there are people who can search them out and who will stand on them. There are as many ideas and ideals as there are men of good will who will hold them in their minds and act them in their lives.
A. listening to people's opinions
B. revolutionary changes
C. being happy or unhappy
D. the way it is lived
E. we give part of ourselves away
F. many roads to the attainment of wisdom
G. as a short gap between birth and death
We are living in a periods of
Will he need bones of steel and powerful muscles to resist rocket thrust，the lungs of a glass blower，a mighty heart，the calmness of an acrobat，unconscious death urges，or a schizophrenic(患精神分裂症的)drove toward isolation？ Popular ideas of a spaceman tend to be funny composites of fiction and fact.
A more realistic portrait emerges from the young science of bioastronautics，the newest and strangest of medical disciplines.The astronaut may be described as a young man of high intelligence who is normal to an abnormal degree.On earth he may well have been a high diver，high jumper，pole vaulter，or acrobat.He must be highly motivated，carefully trained，and he must want to come back.
His heart and lungs must be healthy but need not be exceptionally developed，for his cabin will be pressurized.Huge muscles may actually be disadvantageous，for he will have almost no way to get exercise，and he will find that the strength of a year old child is adequate in the weightlessness of space.A firm body and a short， strong neck will help him to withstand(抗拒;经得起……)the tremendous forces encountered at take off.Most important physically，his digestive system must be one that will not be upset by weightlessness;he must not be subject to motion sickness.
() 41.All the following are popular beliefs about the future spaceman EXCEPT that .
A.faced with isolation，he is brave enough and not liable to go mad

Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform. some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal
A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform. tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
These modern and potential computer uses are possible because of the silicon microchip.
These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
What is the purpose of the passage？
A．To tell the readers what computers will look like in the future.
B．To show the close relations between man and computers.
C．To tell the readers how important silicon microchips are.
D．To talk about the possible future uses of computers.
