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.
Most people ______.
A．are left-handed
B．are right-handed
C．can use both hands equally well
D．never use left hands
Some of the computer experiments now going inspire imagination of the future. For example, scientists are working in devices that can electronically perform. some sight and hearing functions, which could make easier for the blind and deaf. They are also working on artificial arms and legs that respond to the electric impulses (脉冲) produced by the human brain. Scientists hope that someday a person who has lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized effects in movies, and real-life training machines now being used by the U. S. Army are causing some people to predict new educational uses for computers. Computers could someday be used to imitate travel to other planets, to explore the ocean floor or to look inside an atom.
Experiment with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals (终端) . Cars, too, might be equipped with computers to help drivers find their way around or to communicate with home and office computers.
Many people, including handicapped (残废的) 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.
Which of the following would be the most appropriate title for the passage？
A．Futurists and Computers
B．A Look at Future Uses of Computers
C．Computer Experiments
D．Scientists and Computers
In the author's opinion,______.
A. it is true that life in America is much faster than that in any other city
B. people living outside big cities are lazy and miserable
C. most American people enjoy living in the suburbs of big cities
D. those who are busy are not necessarily unfriendly
People who hold the opposite opinion(mainly men)have an answer to this. They say that men have more responsibility than women; a married man is expected to earn money to support his family and to make the important decision, and therefore it is right for men to be paid more. There are some people who hold even stronger opinion than this and are against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full time job, they will be unable to do the things. Women are best at making a comfortable home and bringing up children. They will have to give up their present position in society.
This is exactly what they want to give up, the women who disagree say. They want to escape from the limited place which society expects them to fill, and to have freedom to choose between a job and home life, or mixture of the two. Women have the right of equal pay and equal opportunities.
These women have expressed their opinions forcefully by using the famous saying, "All men are created equal. " They point out that the meaning of this sentence is "all human beings are created equal."
The women use the phrase "equal pay for equal work" to demand that ______.
A．women's work shouldn't be harder than men's
B．men should be paid less than women
C．people doing harder work should earn more
D．men and women should be paid the same amount of money for the same work
People may be the most interesting show in a large city. Stroll through busy streets and see what everybody else is doing. (79) You will probably see people from all over the world; you will certainly see people of every age, size, and shape, and you' II get a free fashion show, too. Window - shopping is also a safe sport -- if the stores are closed.
Check the listings in your neighborhood paper. Local colleges or schools often welcome the public to hear an interesting speaker or a good debate. The film or concert series at the local public library probably won't cost you a penny. Be sure to check commercial advertisements too. A flea market can provide hours of pleasant browsing. Perhaps you can find a free cooking or crafts demonstration in a department store.
Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may save some money, too, since these places often set aside one or two free admission days at slow times during the week. Pretend that you are a tourist from time to time, and get to know your city all over again including the indispensable sights that people travel miles to see. If you feel like taking an interesting walk, find a free walking tour, or plan one yourself. You will see your city in a new perspective once you know more about its history or its architectural treasures. With imagination and a spirit of adventure you can quite easily find good entertainment at no cost at all.
Which of the following statements is NOT true？
A．There are many kinds of amusements you can enjoy with spending no money.
B．The film shown at the local public library is often free of charge.
C．Local colleges often hold meetings to debate the issues people are interested in.
D．You should be a tourist if you want to know more about the city you live in.

When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people olden became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
We should take good care of our eyes ______.
A．only when we can see well
B．only when we cannot see perfectly
C．even if we can see dell
D．only when we realize how important our eyes are

People who are near-sighted can only see things that are very close to their eyes.' Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
