Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.

The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.

The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.

Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecules. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

49. What is the text mainly about?

A. The terrible conditions in the Antarctic. B. A special fish living in freezing waters.

C. The ice shelf around Antarctic. D. Protection of the Antarctic cod.

50. Why can the Antarctic cod live at the freezing temperature?

A. The seawater has a temperature of -1.88℃.

B. It loves to live in the ice-salt mixture.

C. A special protein keeps it from freezing.

D. Its blood has a temperature lower than -2.05℃.

51. What does the underlined word “it” in Paragraph 5 refer to?

A. A type of ice-salt mixture. B. A newly found protein.

C. Fish blood. D. Sugar molecule.

52. What does “glycol” in the underlined word “glycoprotein” in the last paragraph mean?

A. sugar B. ice C. blood D. molecule

Sometime in the next century, the familiar early-newspaper on the front porch (门廊) will disappear. And instead of reading your newspaper, it will read to you. You’ll get up and turn on the computer newspaper just like switching on the TV. An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You’ll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events.

Most of the technology is available now, but convincing more people that they don’t need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of traditional newspapers unavoidable.

Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 to 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry.

1. Which of the following is NOT an advantage of computer newspapers?

A. They are cheaper than traditional newspapers.

B. They are more convenient to read.

C. You can choose the kind of voice you want to hear.

D. You can easily save information for future use.

2. Which of the following is a reason why it will take a long time to complete the changeover?

A. The technology is impossible now.

B. Computer newspapers are too expensive.

C. The popularization of computers needs a long time.

D. Traditional newspapers are easier to read.

3. It can be inferred that journalists are against computer newspapers because _______.

A. they don’t know how to use computers

B. they think computer newspapers take too much time to read

C. they think the new technology is bad

D. they have been trained to write for traditional newspapers

4. We can infer from the passage that _______.

A. all technological changes are good

B. new technologies don’t always replace old ones

C. new technologies will eventually replace old ones

D. traditional newspapers are here to stay for another century

5. What is the best title of the passage?

A. Computer newspapers are well liked.

B. Newspapers of the future will be on the computer.

C. Newspapers are out of fashion.

D. New communications technology.

Do you think it is ever a good idea for a teenager to have a credit card?

My kids watch closely as I swipe the card through the register．They’ve seen me do it hundreds, thousands of times．Cool．They are itching to swipe it through the machine themselves． When we walk out of the store with our groceries or pet food, or whatever, it’s almost as though money has not changed hands, painless, easy．

So it shouldn’t be shocking to discover that teenagers are becoming card carrying consumers in their own right．The question is, should they?

While some argue it’s best to teach kids how to use a credit card while still living under the family roof, not everyone agrees． Dave Ramsey, financial expert says getting a credit card for your teenager is actually, “an excellent way to teach him or her to be financially irresponsible．”

Now parents are required to co-sign on credit cards for children under 21．“If their name is on the credit card, then the parent may say, ‘Hey, my name is on this．Don’t get me into trouble,” says Mary Beth Pinto, a marketing professor．“When parents were the co-obligors（共同借贷人），the children caused less debt．If the parents are the co-obligors, the tendency is that the parents were explaining how to use the cards．” Still, Pinto believes parents should start the process much earlier．“Yes, there has to be teaching going on and it has to start when they’re younger． You’re not going to get rid of credit cards．They are here to stay． You have to have them． You can’t fight progress,” Pinto said．

Ramsey, however, disagrees．“Throwing teens into a pool of （credit）sharks is a sure way to guarantee a life-time of heartache,” he said．“You can make online purchases and rent a car with a credit card．Of course, you must have money in your bank account before you can make a purchase with a credit card．But paying for things with money is what you are supposed to do．”

1.The author mentioned her experience in Para 2 mainly to______．

A． prove the convenience of using credit cards

B． tell what impression credit cards leave on kids

C． give advice on using credit cards wisely

D． explain the pleasure credit cards bring to customers

2.The underlined word in Para 2 can be replaced by __________．

A． eager B． afraid C． embarrassed D． thankful

3.What’s Ramsey’s attitude towards teens’ using credit cards?

A． He feels it is worth a try

B． He is very supportive

C． He is strongly against it

D． He considers it as a pleasant experience

4.Pinto will most likely agree that __________．

A． parents should let teens own their credit cards earlier

B． you shouldn’t be in control of credit cards

C． it is never good for anyone to get a credit card

D． learning to use credit cards is practical

You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the back of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can resist massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

1.What does the author say about the black box?

A. It ensures the normal functioning of an airplane.

B. The idea for its design comes from a comic book.

C. Its ability to resist disasters is incredible.

D. It is an indispensable device on an airplane.

2. What information could be found from the black box on the Yemeni airliner?

A. Data for analyzing the cause of the crash.

B. The total number of passengers on board.

C. The scene of the crash and extent of the damage.

D. Homing signals sent by the pilot before the crash.

3.Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. Too much space was needed for its installation.

C. The early models often got damaged in the crash.

D. The early models didn't provide the needed data.

4. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

A. To distinguish them from the colour of the plane.

B. To caution people to handle them with care.

C. To make them easily identifiable.

D. To conform to international standards.

5.What do we know about the black boxes from Air France Flight 447?

A. There is still a good chance of their being recovered.

B. There is an urgent need for them to be reconstructed.

C. They have stopped sending homing signals.

D. They were destroyed somewhere near Brazil.
