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 us 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 manmade 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.

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

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.

Even in the fanciest pizza restaurant, you will never feel weird if you ask for a box to take your leftovers (剩饭）home. In Italy, that will soon apply everywhere, with a new law that encourages restaurants to give people doggy bags, although in Italy it's called a "family bag."

The new law is designed to reduce food waste and open doors to companies wishing to donate wasted food. Family bags were made to avoid embarrassment at asking for leftovers, turning it from begging into good behavior.

In the U.S., taking uneaten food home is normal. In the U.K. it is fairly common. To the south, though, this practice is rare. In Spain and Italy, people might take the bones from their meat and give them to their dogs, but culturally, it's not the done thing. Also, there aren't often many leftovers, as dishes are sized according to how much people will actually eat and are rarely too big to finish unless you over-order.

In France, the laws are tougher. Last year, the French began to forbid supermarkets to throw away food. They must either give it away to charity, or make it available to be used as animal feed and compost(堆肥），If they fail to follow the law, they will be fined.

Perhaps Italy's new law is right. Food waste is now attracting international attention, but the only way to really stop it lies in whether individuals are willing to change their ways. If it becomes socially unacceptable to waste food, or to serve a huge portion in restaurants, then we have a chance.

1.What does the underlined word “weird” in paragraph 1 probably mean?

A. Difficult.　　 B. Strange

C. Relaxed.　　 D. Disappointed.

2.Why do the Spanish seldom take leftovers home from restaurants?

A. They don’t bother to do it.

B. It is their custom to eat food up.

C. It is not acceptable in their culture.

D. They usually order small portions.

3.According to the author, how can we reduce food waste?

A. By introducing stricter laws.

B. By donating food to the needy.

C. By restaurants only serving small portions.

D. By everyone taking action and saying no to it.

4.What’s the text mainly about?

A. Way of reducing food waste.

B. Italy’s plans to use family bags.

C. How doggy bags come into being.

D. The increasingly serious food waste.

高二英语单项填空困难题查看答案及解析

If you see a group of people dancing and singing on the street or in the railway station, you don’t need to feel surprised. They are a flash mob. Don’t be confused by their name. Actually, a flash mob, organized with the help of the Internet or other digital communications networks, is a group of people who assemble suddenly in a public place, do something unusual for a period of time, such as exchanging books, coming together to look at the sky, waving their hands and shouting something at the top of their lungs for 30 seconds, and then quickly disappear before the police can arrive.

Bill Wasik, senior editor of Harper’s Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob assembled on June 3, 2003 at Macy’s department store involving 100 people gathering on Macy’s Department Store. Following this, about 200 people flooded the lobby of the Hyatt hotel, applauding in one voice for fifteen seconds, and next participants pretending to be tourists on a bus trip invaded a shoe boutique in Soho. A later mob saw hundreds of people in Central Park making bird noises.

Wasik claimed that he created flash mobs as a social experiment designed to tease hipsters（追逐时尚的人）, and highlight the cultural atmosphere of agreement and of being part of “the next big thing”.

Many Web logs, chat rooms and Web groups are devoted to the craze. Though flash mobs were originally regarded as pointless, the concept has already developed for the benefit of political and social events. Flash mobbing takes advantage of the efficiency of communicating information on Websites and by email, and protesters can similarly use the “on and off” concept to be involved in political events. Such flash mob gatherings can sometimes shock or frighten people who are not aware of what is taking place. They also have enormous economic potential, such as using flash mobs to advertise a product.

The flash mob is now becoming more and more popular. People use it to do many things. For example, in 2009, hundreds of Michael Jackson’s fans took part in a flash mob to remember him, gathering outside the railway station in Liverpool, singing and dancing Michael’s famous song Beat It together. In another example, some people took part in a flash mob to warn people against negative words. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

1.The purpose of flash mobs created by Wasik is to __________.

A. make flash mobs a social experiment with political, social and economic potential

B. give people an opportunity to assemble and perform some distraction

C. make fun of hipsters and emphasize the cultural atmosphere of agreement and participation

D. make communicating information efficient and help people create a memory

D. they assembled in the department store and applauded together for 15 seconds

3.Which of the following could most possibly be a flash mob according to the passage?

A. Sixteen people get together quickly on the square and do jumping and singing and leave there suddenly.

C. Some tourists plan for months and go mountaineering on the first day of Horse Year.

4.Which of the following might be the best title of the passage?
