If you want to cook something quickly, you heat it from both sides.That's what's happening to the West Antarctic ice sheet(南極洲西部冰蓋)．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?zé)崮?．While the CO2 we send out heats the atmosphere above the continent, earth is melting its ice from below.

If you were to drill (鉆)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?zé)崽荻?．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.

Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers（低頭族）.

Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated the damage phubbing can bring is real.

Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

1.For what purpose does the author give the example of a cartoon in Paragragh2?

A. To inform people of the bad effects of phubbing.

B. To advertise the cartoon made by students.

C. To indicate the world will finally be destroyed by phubbers.

D. To warn doctors against using cell phones while treating patients.

2.Which of the following is NOT a risk a phubber may have?

A. His social skills could be affected.

B. His neck and eyesight will be gradually harmed.

C. He will cause the destruction of the world.

D. He might get separated from his friends and family.

3.Which of the following may be the author’s attitude towards phubbing?

A. Supportive. B. Negative.

C. Optimistic. D. Objective.

4.What may the passage talk about next?

A. Advice on how to use a cell phone. B. People addicted to phubbing.

C. Results of phubbing. D. Measures to reduce the risks of phubbing.

A person, like a commodity（商品）, needs packaging. But going too far is absolutely undesirable. A little exaggeration(夸張) will do no harm when it shows the person's unique qualities to their advantages. To show personal attractiveness in a casual and natural way, it is important for one to have a clear knowledge of oneself. A skilled packager knows how to add art to nature without any signs of embellishment so that the person so packaged is not a commodity, but a human being, lively and lovely.

A young person, especially a female, shining with beauty and full of life, has all the favor granted. Youth however, comes and goes in a flash. Packaging for the middle-aged is primarily to hide the marks made by years. If you still enjoy life enough to keep self-confidence and work at pioneering work, you are unique in your natural qualities, and your attractiveness and grace will remain. Elderly people are beautiful if their river of life has been, through plains, mountains and jungles, running its course as it should. You have really lived your life, which now arrives at a self - satisfied stage of quietness and calmness with no interest in fame or wealth. There is no need to make use of hair dyeing. The snow-capped mountain itself is a beautiful scene of fairyland. Let your looks change from young to old in step with the natural ageing process so as to keep in harmony with nature, for harmony itself is beauty, while the other way round will only end in unpleasantness. To be in the company of the elderly is like reading a thick book of good edition, which attracts one so much that one is unwilling to part with it. As long as one finds where one stands, one knows how to package oneself, just as a commodity sets up its brand by the right packaging.

1.The underlined word in the first paragraph is closest to the word ______ in meaning.

A. decoration B. clarification

C. movement D. identification

2.It can be concluded from the text that ______.

A. people should be packaged at all ages

B. people should be packaged in a special way

C. elderly people also care about packaging

D. proper packaging makes people attractive

3.For the middle-aged, attractiveness ______ .

A. hardly exists B. is the strongest

C. comes from the inside D. comes from the appearance

4.According to the author, if you want to keep in harmony with nature, you should ______.

A. dye your hair B. make up at a young age

C. follow the ageing process D. give up fame and wealth

5.The underlined sentence means that elderly people ______.

A. are usually packaged like a finely-made book

B. experience a lot and have rich knowledge of life

C. do a lot of traveling and can give you much information

D. enjoy reading thick books about beautiful nature and fairyland
