３１ｓｔ Ｏｃｔｏｂｅｒ —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.
Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.
They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.
Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”
New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.
“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”
The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.
Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”
If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.

C. To make a film about the Arctic exploration.
D. To make people interested in what they are doing.
4.It can be inferred from the passage that ________.
A. ice in the Arctic will disappear in ten years
B. the exploration will last for half a year
C. Hadow spent two years developing a kind of radar, which is about 100 kilograms
D. if there is snow on ice, satellites can’t measure the ice thickness accurately enough

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.
