WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.

The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.

“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.

That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).

Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.

“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.

“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”

In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.

Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.

1.What was the US Geological Survey intended to do?

A. To determine whether the polar bear was in danger.

B. To measure how fast the sea ice melts in the Arctic.

C. To check the predictions of the computer models.

D. To find out the exact number of the polar bear.

2.What causes the polar bears to disappear by 2050?

A. The pollution of the Arctic region. B. The sea ice melting at high speed

C. Fewer food sources being left. D. The temperature getting colder.

3.The key to preventing polar bears dying out seems to _______________.

A. help young polar bears to survive the cold winter

B. have large number of seals living in the oceans

C. make sure there is enough sea ice in the Arctic

D. provide chances for adult polar bears to reproduce

It’s as important to live well as it is to study well, I think. I went to bed no later than 11:30 pm. It put me in the right mood for the next day. I didn’t follow a special diet (饮食), but I did make sure I ate a nutritious breakfast each day.

The person who plays well, studies well. Having a lot of schoolwork doesn’t mean having to give up on every other activity. I played basketball or took a walk to relax when I felt tired. Time out is not a waste of time but helps you study more efficiently.

Besides taking the big exam, you have other choices for college. I took the independent enrollment (自主招生) exam held by Peking University and some other students even prepared to study abroad. Pay attention to any relevant information you can find, whether it’s from school, the news media or another source.

Online shoppers would rather receive an offer for a product or service than make their own offer ₃ according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的）process that seemingly can give consumers more confidence to drive a hard bargain_,said Don Conlon ，Professor of Management in MSU’s Broad College of Business.

But the study found that participants who made their own offers were less successful in sealing the deal and ，when they were successful_? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy，and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer ” Conlon said. ^u People tend to be happier when they’re in the receiver role. ”

Online spending in the United States is expected to jump 45 percent in the next four years， from $ 226 billion this year to $ 327 billion in 2017，according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o£ shoppers. Conlon^’s study is ，obviously, a rare exception.

Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ，which provides offers. Using these two models ，Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ，but they also secured more deals in that receiver role. Further ，when they had to make the bids ，they were left more mentally taxed and regretful.

From an industry perspective，putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products₃ ” Conlon said，“you may want to be the one making the offers. ” However, when selling single items, such as an antique car， accepting bids may be a better option since that typically drives up the price, he said.

About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.

We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was

wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.

The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures in front taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood of the scene so that they looked as if they were at the water’s edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!

Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film "stars"!

1.Who is the author?

A．A cameraman.

B．A film director.

C．A crowd-scene actor.

D．A workman for scene setting.

2.What made the author feel cold?

A．The heavy snowfall.

B．The man-made scene.

C．The low temperature.

D．The film being shown.

3.What would happen in the "three minutes" mentioned in the last paragraph?

A．A new scene would be filmed.

B．More stars would act in the film.

C．The author would leave the studio.

D．The next scene would be prepared.
