Temperatures at Hudson Bay have risen by one half degree Fahrenheit every decade since 1950. Winter ice on the bay melts three weeks earlier than it did just 25 years ago, which means three fewer weeks of polar bear mealtime. Result: Polar bears are 10 percent thinner and produce 10 percent fewer cubs than they did 20 years ago. And though climatologists hotly debate the causes behind Earth's Arctic meltdown, "these changes are startling and unexpected," says James McCarthy, co-leader of the United Nations Intergovernmental Panel on Climate Change.
The plight of polar bears is just the tip to the iceberg when it comes to mounting evidence of global warming. "There's definitely a stark contrast with the way things were at the start of the 20th century," says atmospheric scientist Leonard Druyan, of Columbia University. Recent data show the volume of Arctic sea ice has shrunk 20 percent since the 1950s; glaciers around the world are melting at rapidly increasing rates. Rivers and lakes in North America, Asia, and Europe now freeze about nine days later and thaw 10 days earlier than they did a century ago.
Most scientists believe the only effective strategy to halt global warming is to drastically reduce emissions of powerful air pollutants like carbon dioxide, which accounts for two-thirds of all greenhouse gases. In the last 150 years, the surging use of fossil fuels—coal, oil, and natural gas—has released 270 billion tons of carbon into the air in the form. of carbon dioxide. Fortunately, oceans, plants, and soils absorb more than half of all atmospheric carbon dioxide—without them world temperatures might have already soared at an alarming rate.
By saying "Spring is usually prime food time for 1,200 polar bears"(Line 1, Para. 1), the author means that ______.
A．spring is usually a good time for polar bears to carry out their mating rituals
B．the polar bears usually eat a lot in the spring
C．spring is generally a good time to hunt polar bears
D．polar bears usually hibernate in the spring

听力原文： The quest for success always begins with a target. As Yogi Bear once said, "You've got to be very careful if you don't know where you're going, because you might not get there." Too many people wander through life like sleepwalkers. Each day they follow familiar routines, never asking, "What am I doing with my life？" And they don't know what they are doing because they lack goals.
Goal-setting is a focusing of the will to move in a certain direction. Begin with a clear conception of what you want. Write clown your goals and date them—putting them into words and clarifying them. Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute goal-setting that yields the true sense of satisfaction we all need.
It's important to visualize yourself accomplishing your goal. While losers visualize the penalties of failure, winners visualize the rewards of success. I've seen it among athletes, entrepreneurs and public speakers.
I've done it myself. I was terrified of air travel. I had read too many articles describing crash scenes and imagined these scenes vividly. Friends quoted statistics contrasting air and highway safety, but it made no difference. I had the opportunity to fly on a private plane with friends to a resort. I didn't want to miss out on a great vacation. So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing. When the day arrived, I was eager to go. To everyone's surprise, I got on the plane and flew. I loved every minute of it, and I still use the techniques I employed that day.

W: Thanks.
M: OK, I'll show you. Let's start with the lower level. See？ Here？ You arrive by taxi or bus or whatever here, on the right, can you see？ That's the bus terminal. And you go ill through the main entrance. (23)You could go to the Water World first but I think you'd better skip that as you're short of time.
W: I can see the cable cars.
M: OK, walk past the cable car terminal, at tile bottom of the plan, (24)and bear right past the Waterfall Gardens. Actually, have a look in, there are ducks and other birds in the pool there--it's very pretty. Then you'll see some steps up on the left. Follow that path and you'll come to tile Centenary Garden which is a good place to stop and take pictures if you've got your camera.
W: What's the next place？
M: Then carry on until you're almost at the Children Zoo. It takes quite a long time to walk around. But I do recommend the "touch and feed" section opposite, as I said. (25)The Fun Fair is very interesting, but it's great fun for older children.

听力原文：W: Why are you doing going through all these newspapers？
M: Oh, you know, I've just come back from New York. I'm trying to find a house for my family to live in. But I've got to go through all these advertisements here and just can't find anything good. What shall I do？
W: Well, what do you and your family really want？
M: All we need is a comfortable three-bedroom house.
W: Why don't you take this. It's in the city center and has three bedrooms, a bathroom, a modern kitchen, a lounge, and a dining-room. The price is reasonable.
M: But look here. It's near the railway station, too noisy. And my wife prefers a quiet place. She can't bear any noise.
W: Well, I know of a four-bedroom house in the suburbs. It's got a garden and a garage.
M: That sounds good. Is there shopping nearby？
W: I think so, but I'm not sure.
M: Would it be very far from our company？
W: About 20 minutes' drive. Another important point is, there are a lot of trees around the house and the air is always fresh. By the way, it is much cheaper than that in the city center.
M: That's very nice. I'll talk it over with my wife.
(23)
A．Reading newspapers.
B．Reading advertisements.
