The most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”
“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 drinking coffee and 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. Sometimes it’s down for 10 minutes, sometimes for two hours. There’s no way we can find out without asking the computer, and since it’s down it won’t answer us.”
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 couldn’t tell without asking the computer.”
“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington, ” I suggested.
“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”
“Is there any other airline flying to Washington within the next few hours?”
“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 went white, some people started to cry and still others kicked their luggage.The best title for the article is _______.

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.
Whatever it takes for us to reduce pressure is important to our emotional health, and crying seems to work well. A study has found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendlier and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don’t even know we’re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying-holding back tears of anger, pain or suffering-can be bad for physical health, studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don’t fight it. It’s a natural-and healthy-emotional response.It can be inferred from the text that ___.
| A．there are two ways to keep healthy |
| B．crying does more good to health than laughing |
| C．laughing plays a more important role than crying |
| D．emotional health has a close relationship to physical health |
According to the author, which of the following statements is true?
| A．Crying is the best way to help from others. |
| B．Fighting back tears may cause some health problems. |
| C．We will never know our deep feeing unless we cry. |
| D．We must cry if we want to reduce pressure. |
What might be the most suitable title for the text?

Biomass energy(生物能)，often forgotten as a promising alternative(替代物) to oil, received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta, Georgia, late in April, 1990. Nearly 1,700 scientists, businessmen, and policy-makers, one-quarter from the foreign nations, gathered for a week to discuss various means of squeezing usable energy out of trees, crops, manure, seaweed, algae, and urban waste. Biomass in the United States contributes 2.5 percent of the total supply, but this amount can be doubled by 2000 and then doubled again by the year 2010.
Eight percent of Sweden’s energy supply, for example, is presently coming from wood bark and pulp remainings. Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow and birch.
Brazil is frequently pointed to as a nation with a major successful investment(投资) in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol(酒精) mixture, replacing 10 percent of its previous oil supply. Brazilian representatives(代表) at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost government programs.In Line 2, the phrase “received its day in the sun” most probably means “___”.
| A．come to the public mind |
| B．had its turn in the sun light |
| C．was regarded as a solar energy |
| D．came from the energy of the sun |
Of the total supply in 2010, biomass in the U.S. will be ___ .

Computers are very important to modern life. Many people think that in the future computers will be used in lots of everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be no more books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy food. Most telephone calls will be made by computers, too.
Some people are glad about these new ways of shopping and communicating. Others do not think that computers will replace our old ways.
Let’s look at books, for example. Some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won’t need to turn lots of pages and paper will be saved. Computerized(计算机化) books will be used more and more.
Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won’t change these two habits.In paragraph 1 it is thought people will use computers for ___.

Strange stones of Costa Rica
One of the strangest mysteries in archacology was discovered in the Diquis River Delta, in southern Costa Rica. Since the 1930s, hundreds of stone balls have been found. They range in size from a few centimeters to over two metres in diameter.
Who made these perfect spheres(球体) and how they made them remains a mystery. Some researchers believe the stones were made by extreme heating followed by cooling. People could have polished the spheres with sand or leather. The ancient Costa Ricans had no written language so there is no written record of just how they made the spheres.
Almost all are made of granite (花岗岩), a hard stone created by volcanoes. The granite quarries(采石场) were 25 to 30 miles away from the largest stones, which weigh more than 10 tons each. Nobody knows how people moved them..
Many of the stones have been found near the remains of houses or graves. Some believed that the stones contained hidden treasures and a few have been smashed but nothing has been found inside. Despite these losses, the National Museum of Costa Rica has recorded 130 spheres. However, many stones are not included because they have been removed from their original sites and used as ornaments(装饰) in homes, gardens and churches. Clearly, there are also many stones that lie undiscovered.The stones were discovered ___ .

Many animal and plant species have become extinct and many more are in critical danger. Finding ways to protect the earth’s wildlife and protect the natural world they inhabit is now more important than ever.
Now many animals remain threatened with extinction as a result of human activity.
The dodo is a classic example of how humans caused damage to the earth’s wildlife. The flightless dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fallen fruit from the island’s trees and lived safely until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs and monkeys. The population of dodos rapidly decreased and the last one was killed in 1681.
The rhino(犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa, Europe and Asia, most rhinos now live in protected natural parks and reserves. Their numbers have rapidly decreased in the last 50 years, and the animal remains constantly threatened by hunters.
The last 100years has seen a 95% reduction in the numbers of remaining tigers to between 5,000 and 7,000 and the Bali, Javan, and Daspian tigers are already extinct. The South China tiger is close to disappearing, with only 20 to 30 still alive. Like the rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicine. These items are traded illegally along with tiger skins.
The World Wildlife Fund is actively involved in many areas of the world fighting to protect the natural habitats of endangered animals from further damage and curb the activities of hunters. Our own efforts at home and in the workplace can also make a difference. By reducing waste and pollution, saving water, wood, and energy, and reusing and recycling whenever possible, we can reduce the possibility of even more animals being lost, never to return.The purpose of this passage is to ___.
| A．call on us to protect the earth’s wildlife |
| B．let us know about the animal world |
| C．tell us many animals are in great danger |
| D．tell us why many animals are becoming extinct |
The common reason why many animals are facing extinction is that ___ .
| A．they are too easily controlled by humans |
| B．they can be made into highly prized medicine |
| C．they can provide people with delicious meal |
| D．humans kill them for their own interests |
Which of the following statements about the dodo is TRUE according to the passage?
| A．It was native to the Island of Mauritius and could fly very well. |
| B．It struggled to survive until human arrived in 1505. |
| C．Its population decreased only because pigs and monkeys were introduced. |
| D．It was possible for humans to find a dodo before 1681. |
The underlined word “curb” in the last paragraph is closest in meaning to “___”.
| A．improve |
| B．limit |
| C．cancel |
| D．criticize |
