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.
The fishes are about 1.5 meters long and look like carps(鲤鱼). There will be a detector intheir bodies. They canfind the sources of pollutionin the water, and then the robot fisheswilleat part of it. Unlike other robots, they don’t need to be controlled by people faraway. Therobots all have an eight-hour battery. They can “swim” in the sea freely and send backinformation to people on the beach. After their batteries die, they will return by themselves.
There are five robot fishes altogether now.Each costs about 29,000 dollars. They are partof a three-year project between engineering company BMT Group and Essex University insoutheastern England.
“We designed the fishes creatively. We hopethe robot fishes can find the changes in the seawater and report back the information,” said Professor Huof Essex University. His team isdeveloping the fishes.
What will the robots do if they find the pollution in the water？
A.They will eat part of it.
B.They will stop working.
C.They will tell people where they are.
D.They will take it out to the beach.
How longcan a battery in their bodies work each time？A.For five hours
B.For eight hours.
C.For twelve hours.
D.For one day.
How much do the five robot fishes cost altogether？ A.$14, 500.
B.$29,000.
C.$145,000.
D.$1,450, 000.
Which of the following is TRUE？ The robot fishes ____.A.can eat anything in the water
B.need to be controlled by people
C.are 1.5 meters long andthey look like sharks
D.cango back to the beach when the batteries run down
What can we learn from the passage？ The robot fishes____.A.have worked around the world
B.can’t take out the trash in the water
C.will helppeopledetect the pollution in the water
D.help to find other fishes in the rivers, lakes and seas

Social scientists are, of course, extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have been developed. As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory. The controversy is often referred to as " nature/nurture".
Two who support the" nature" side of the conflict believe that our personalities and behavior. patterns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, characteristics, and behavior. is central to this theory. Taken to an extreme, this theory maintains that our behavior. is predetermined to such a degree that we are almost completely governed by our instincts.
Proponents of the " nurture" theory, or as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior. is almost completely shaped by their surroundings. The behaviorists view of the human being is quite mechanistic; they maintain that, like machines, humans respond to environmental stimulus as the basis of their behavior.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior. lies somewhere between these two extremes. That the controversy will continue for a long time is certain.
Which of the following statements would supporters of the" nature" theory agree with？
A．A person's instincts have little effect on his actions.
B．Environment is important in determining a person's behavior. and personality.
C．Biological reasons have a strong influence on how we act.
D．The behaviorists' view correctly explains how we act.
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.
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 often 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 (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out of the other eye. You will find the object's relation to the background (背景) 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 cannot see perfectly
B．only when we can see well
C．even if we can see well
D．only when we realize how important our eyes are
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.

根据内容回答下列各题.
Not long ago, there lived in Auckland a working family who dreamed about a house of their own. Anyone then could read in the newspapers about the building companies who offered to put people into a new house 51 only a $1,000 deposit. Of course, the remainder had to be paid off with interest over a period of twenty years or so.
The worker and his wife hopefully went to one of these companies 52 this wonderful offer. And the man in the office said．“Yes, sure. You bring along $1,000 and we can 53 you with a new house.” So the worker and his wife had to work hard and in twelve months’ time they returned to the building man with $1,000. But the man in the office said, “Look, I’m sorry, 54 we’ll need $1,500 now. Costs have gone up since we saw you last, you know.”
The couple thought it over and decided it would not take very long to save the extra $500 if they worked hard. In six moths they worked 55 overtime and saved the $500 in spite of the high rent they had to pay for their flat. Back to the building man they 56 with their $1,500. But to their surprise he 57 the deposit was now $3,000. Now somewhat wiser, the worker said, “And the next time, I dare say we’ll find the deposit rising once more. How have we 58 save the extra $1,500？” “Well”, said the man, “I think we can stabilize the situation for about twelve months. By the time you come with $3,000, we will have had the house 59 for you.
The couple left, sad at heart as they saw their dream house 60 . By the time they had saved the extra $1.500, no doubt the deposit would have become still higher, maybe $5,000, then $10,000 and then…!

Hemingway's style. of writing is striking. His sentences are short, his words simple, yet they are often filled with emotion. A careful reading can show us, furthermore, that he is a master of the pause. That is, if we look closely, we see how the action of his stories continues during the silences, during the times his characters say nothing. This action is often full of meaning. There are times when the most powerful effect comes from restraint (适度). Such times occur often in Hemingway's fiction. He perfected the art of expressing emotion with few words.
The word "stamina" in the last line of paragraph 1 can most probably be replaced by______.
A．money
B．time
C．energy
D．weapon
As our van pulled up to the ranch (牧场) to start a three-month program for troubled boys, we passed a cowboy on his horse. Bill was the owner of the ranch. We made eye contact through the dusty window and he winked (挤眼睛) at me and touched the brim of his cowboy hat in welcome.
All summer long Bill and his ranch-hands taught us to ride horses, chop wood, and round up cattle. We started to understand the value of working with our hands. Knowing how important it was for boys like me to know that someone believed in them, he trusted us to do the job and do it right. We never let him down.
The last day at the ranch, Bill pulled me aside and praised me for the work I had done-not only on the ranch, but also on myself. He told me if I ever needed anything I could count on him.
Four years later, I took him up on that offer. I called him up and asked for a job. I told him how his confidence in me had given me the courage to change my life. He offered me a job on the spot. I’m proud to say that each summer I’m the one in the ranch to open the gate for a van full of young men who need someone to believe in them, so they can learn to believe in themselves.
The author’s first impression of Bill was probably his _________.
A．seriousness
B．friendliness
C．authority
D．generosity
"If your computer is down, just write me out a ticket."
"I can't write you out a ticket. The computer is the only one allowed to do so."
I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do？'
"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."
"So when it goes down, you go down with it."
"That's good, sir. '
"How long will the computer be down？" I wanted to know.
"I have no idea. There's no way we can find out without asking the computer."
After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes？ They're still flying, aren't they？"
"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.
By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people started to cry and still others kicked their luggage.
The best title for the article is______.
A．When the Computer Is Down
B．How to buy a ticket
C．The Computer of the Airport
D．Asking the Computer
