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(備用) 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.

A. When the Computer Is Down             B. The Most Frightening Words

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

What does “these two killers” in the second paragraph refer to ?

A. Gene technology and another treatment of the two diseases.

B. The two murderers who killed the cloned baby

C. The two diseases of cancer and heart disease

D. Hereditary diseases and cancer

What’s the main idea of the third paragraph?

A.  How gene technology can be applied in the field of treating hereditary diseases.

B.  Gene technology can be used to clone human babies.

C.  Gene technology can help people to give birth of a baby.

D.  Gene technology can help the English imperial family out

In what way gene technology can help to treat hereditary diseases?

A. Using gene technology, people with hereditary diseases can have more living days.

B. Using gene technology, scientist finds the wrong gene and corrects it.

C. Using gene technology, human babies can be cloned.

D. Doctors can cure cancer and heart disease with the help of gene technology.

What is the main purpose of writing this passage?

A. Expressing the writer’s idea that gene technology will benefit people

B. Telling people the advantages of gene technology

C. Telling the readers that gene technology will not benefit people

D. Explaining that gene technology will also do harm to the humanity

Sometime early in the next century, human beings will move to Mars．They will live there for about a year, and then will be replaced with another group of pioneers．Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth．

We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures．These resemblances have caused many people to consider a centuries-long project: to terraform Mars．Terraforming means altering a planet’s surface so that Earth’s life forms can survive there．This concept, previously found only in science fiction is now being seriously considered by scientists．

Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth．But it will take at least 300 years．

Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt．The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support．Our very existence and numbers are threatening many other species．We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate．Currently terraforming Earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places．

Small as the possibility of such a project is, it is not impossible．Even if earth-bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth．

The future existence of all the people in our world may very well depend upon our ability to terraform Mars．

What would be the best title for this passage?

      A．Terraforming Mars．       B．Saving the Earth．

      C．Travelling to Mars．       D．A Newly-found Place．

What does the underlined word “altering” mean in the second paragraph?

      A．Warming．         B．Changing．         C．Planting．          D．Building．

According to the passage the main purpose of terraforming Mars is to _____．

      A．do some scientific research work   

       B．find out its similarity to Earth

      C．a(chǎn)void the dying away of many other species   

       D．find on Mars living place for the increasing human beings

The main reason for causing many people to consider terraforming Mars is that _____．

       A．there are some resemblances between Earth and Mars

       B．terraforming Mars is theoretically simple

       C．we have had some experience with terraforming our own planet: Earth    

       D．the development of science and technology is very rapid
