If you want to cook something quickly, you heat it from both sides.That's what's happening to the West Antarctic ice sheet(南极洲西部冰盖).A new study reveals that the area under the ice sheet is far hotter than previously thought, fed by an unexpected flow of geothermal energy (地热能).While the CO2 we send out heats the atmosphere above the continent, earth is melting its ice from below.

If you were to drill (钻)deep at some place on the continents, you would find that the temperature increases about 25℃ for every kilometer deep into the hole on average.Scientists call this the geothermal gradient (地热梯度).Until recently, no one had drilled deeply enough through the West Antarctic ice to determine the geothermal gradient underground.For the new study, researchers drilled all the way through the ice and into the mud.They found that the geothermal gradient was about 200℃,which is several times the global average on continents.Few predicted this result, although it had been showed that the earth below the West Antarctic ice is unusually hot.

Even with the new discovery, though,we still don't know exactly where the heat is coming from.One interesting possibility is volcanoes, which are under the ice.As recently as 2013, scientists were still discovering volcanoes under the ice in the area, and there may be many more.

Some people say that these volcanoes, rather than man?made climate change, are responsible for melting the area's ice.While it's true that heat coming from within the earth, including heat related to volcanoes, makes the melting faster, it is just one contributor to the loss of the West Antarctic ice sheet-not the main cause.Today's study could help us understand how the whole system, including global warming, is melting the ice.

1.What's happening to the West Antarctic ice sheet?

A. The ice sheet is getting hotter and hotter.

B. It is heated from below rather than from above.

C. The ice sheet is producing a new kind of energy.

D. It is melting from both sides.

2.What can be learned from the second paragraph?

A. It was the first time that researchers had tried to measure geothermal gradients.

B. The geothermal gradient showed where the heat came from.

C. The result was beyond the researchers' expectations.

D. Researchers never knew the earth under the West Antarctic ice was hot.

3.The author would probably agree that ________.

A. the new discovery is unhelpful without a certain conclusion

B. no volcano has been found to support the

researchers' idea

C. volcanoes are the most important reason for the melting of the ice

D. global warming is surely one reason for the melting of the ice

4.What's the main idea of the passage?

A. The West Antarctic ice sheet is in danger.

B. Researchers are trying to stop global warming.

C. The West Antarctic ice sheet's melting will bring terrible consequences.

D. It has been known how to stop the melting of the West Antarctic ice sheet.

What is your favorite color? Do you like yellow, orange and red? 1.Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference as well as the effect that colors have on human beings. 2. If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

3. A yellow room makes most people more cheerful and more relaxed than a dark green one. And a red dress brings warmth and cheer to the saddest winter day. 4. A black bridge over the Thames River near London, used to be the scene of more suicides (自杀) than any other bridge in the area—until it was repainted green. The number of suicide attempts fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

5. it is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

A. On the other hand, black is depressing.

B. They tell us, among those facts, that we don’t choose our favorite color as we grow up—we are born with our preference.

C. The rooms are painted in different colours as you like.

D. If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.

E. Light and bright colors make people not only happier but more active.

F. Life is like a picture or a poem, full of different colours.

G. Colors do influence our moods. There is no doubt about it.
