A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.Which of the following statements is TRUE according to the passage?
| A．It has long been expected oxygen sensors exist in mice’s skin. |
| B．People have to surf the Internet to read detailed findings. |
| C．It has been proved that these findings help treat lung diseases. |
| D．Johnson believes that Oxygen sensors also exist in human skin. |
One of the functions of the molecules mentioned above is _______.
| A． increasing level of oxygen | B．improving athletes’ performance |
| C．detecting oxygen | D．carrying oxygen around the body |
What is Johnson’s attitude to the application of the findings to the athletes’ training?
| A． Hesitating | B．Doubting | C．Positive | D．Negative |
The best title of the passage may be _______.
| A． Humans Might Sense Oxygen Through Skin |
| B．Frogs And Mice Are Distant Relatives |
| C．First Known Animal Breathes Through Skin |
| D．Great Findings Benefits Athletes A Lot |
The long, lonely voyage of the Japanese ghost ship is over.
A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year’s tsunami (海啸), sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed to shipping and the coastline on Thursday.
The cutter’s guns tore holes in the 164-foot Ryou-Un Maru, and then it began to take on water and lean to one side. In about four hours, the ship disappeared into the sea, said Chief Petty Officer Kip Wadlow.
The ship had no lights or communications system, and its tank was able to carry more than 7,570 liters of diesel fuel. Officials, however, didn’t know exactly how much fuel was aboard.
“It’s less risky than it would be running into shore or running into other ships,” coast guard spokesman Paul Webb said.
The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it is safer to sink the ship than let the fuel evaporate and pollute the sea environment.
Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of refrigerators, washing machines, televisions, roofs and fishing nets heading toward North America since last March when a magnitude-9.0 earthquake struck Japan.
As the coast guard was ready to fire on the vessel, a Canadian fishing vessel, the 19-meter Bernice C, claimed the rights to save the ghost ship in international waters.
Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it.
Then the Canadian boat left, and once it was about 10 kilometers from the Japanese vessel, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition (弹药)twice that size.
State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant, to see if Alaska residents, seafood or wild animals could be affected.The plan to fire on the Japanese ghost ship was paused because ____________.
| A．the ghost ship was beyond the reach of the Coast Guard’s guns |
| B．state officials worried the ghost ship might give out radiation |
| C．the shells were not powerful enough to sink the ghost ship |
| D．a Canadian fishing boat wanted to save the ghost ship |
What’s the right order of the events related to the ship of Ryou-Un Maru?
a. Its long, lonely voyage came to an end.
b. The US Coast Guard sank it into the sea.
c. The ship began to float across the Pacific Ocean.
d. A big tsunami was caused by great earthquakes.
e. Bernice C claimed rights to save the ghost ship.
| A．d, c, e, b, a | B．a, b, d, c, e | C．c, e, d, a, b | D．b, a, d, c, e |
Which of the following could be the best title for the passage?
| A．Japanese ghost ship arriving at US |
| B．Tsunami garbage heading to US |
| C．Japanese ghost ship polluting the Pacific |
| D．Cannon fire sinking Japanese ghost ship |
●Ms Tan, you’ve referred to your new novel as your eighth book.
That’s because it took me six or seven attempts at a second novel before I started and completed this one.
●Why do you think you had so many false starts?
I would say that my reasons were wrong. I was trying to prove that I wasn’t just a mother-daughter storyteller, or I was trying to prove that I didn’t just have to write about things that were strictly Chinese or Chinese-American. Those were never the right reasons for writing those early stories. And I could never come up with other better reasons for continuing them.
●What kept you going on this book?
This book was different because it was based on my mother’s real life. The reason for writing it became more personal and emotional. After The Joy Luck Club came out, my mother was always explaining to people that she wasn’t any of the mothers in that book. And at one point she said to me, “Next book tells my true story.” And then she started telling me things I never knew before. She also told me many, many stories, because my mother doesn’t generalize(笼统地表达). The book really grew out of that.
●Have you ever visited China?
Yes. I’ve been there twice: about three years ago and then again last November, both times with my mother and my husband.
●Was it difficult to understand the Chinese-American dialect(方言) without sounding like a parody(拙劣的模仿)?
No, because it’s the language I’ve heard all my life from my mother. She speaks English as it’s direct translation from Chinese. But it’s more than that. Her language also has more imagery than English.
●Can you think of an example?
Somebody might say to me, “Don’t work so hard. You’ll kill yourself.” My mother will say to me，“Why do you press all your brains out on this page for someone else？” So it’s very vivid. That’s the way she talks.
●Have many readers told you that the Chinese mother in your book reminded them of the typical Jewish (有癖好的) mother?
Many people have told me that. I think the mother-daughter relationship is very intense(紧张) in both cases. Culturally there is an acceptance that mothers have the power to tell their children, especially their daughters, how to conduct their lives --- not simply up until the time they are 18, but for the rest of their lives. However, when children grow up in a different culture from their parents’，they tend to keep more secrets from their parents. The children think, “They just wouldn’t understand that I had to do this.” And that can really create a gap, and it can grow as the number of secrets grows.Based on the questions in this interview, what do you think Ms Tan’ s profession is?
| A．A journalist. | B．A story-writer. | C．An interviewer. | D．An interviewee. |
What’ s TRUE about Tan’ s second book?
| A．It’ s about her real life in America. |
| B．The name of the book is The Joy Luck Club. |
| C．It is the result of many times of carefull thought. |
| D．It includes many works of her mother. |
Which question is NOT answered in the interview?
| A．How does she think of her mother’ s language? |
| B．How many books does she plan to write? |
| C．When did she visit China? |
| D．How is generation gap created? |
We can infer that________.
| A．Tan’ s mother is a good storyteller |
| B．Tan plans to write another book about her mother |
| C．Tan plans to return to China |
| D．Tan’ s mother is hard to communicate with because of personality |
The last paragraph mainly talks about________.
| A．how to keep secrets from parents |
| B．how to deal with the mother-daughter relationship |
| C．how to conduct the lives |
| D．how the generation gap comes about |
Every few years, two groups carry out a study of how many Americans wash their hands after using the toilet. These groups are the American Society for Microbiology and the American Cleaning Institute, formerly the Soap and Detergent Association.
There was good news in the latest study. Researchers found that eighty-five percent of adults washed their hands in public restrooms last month. That was the most since the studies began in 1996.
Researchers visited restrooms at a baseball park in Atlanta and a science museum and aquarium(水族馆) in Chicago. They also visited two train stations in New York City and a large farmers’ market in San Francisco. In all, they observed about six thousand adults, with females and males equal in number.
The researchers found that seventy-seven percent of men and ninety-three percent of women washed their hands. That was up from sixty-six percent of men and eighty-eight percent of women in the last study three years ago.
The lowest rate of hand washing among men was at Turner Field, home of the Atlanta Braves baseball team. Only sixty-five percent of men washed their hands, compared to all but two percent of women.
Chicago and San Francisco had the most hand washers—eighty-nine percent of adults. Atlanta followed at eighty-two percent. New York had the lowest rate, at seventy-nine percent of the adults observed at Grand Central Station and Penn Station.
The findings of the observational study conflicted(不一致) with the findings of a separate telephone survey of about one thousand people. Ninety-six percent of them said they always washed their hands after using public restrooms.
Almost nine out of ten also said they always washed after using the bathroom at home.
Hand washing can help prevent the spread of many different infections.
To clean your hands well, wet them first and rub in soap for at least twenty seconds, including between the fingers and under the nails. Then wash under running water. In a public restroom, if you dry your hands with a paper towel, you should also use the towel to shut off the water and open the door.
Hand washing is also important when preparing food and after changing a baby’s diaper(尿布). You should also wash if you cough or sneeze into your hands.According to the latest study, about ____ women washed their hands after using public bathroom.
| A．1,980 | B．2,310 | C．2,640 | D．2,790 |
Which of the following shows the right order of washing hands correctly?
a. Wash your hands under running water.
b. Rub your hands in soap for not less than twenty seconds.
c. Wet your hands.
d. Dry your hands with a paper towel.
e. Open the door, using a paper towel.
f. Shut off the water with a paper towel.
| A．cbdaef | B．cdabfe | C．cbadfe | D．cdabef |
Which of the following can be the best title for the passage?
| A．Hand washing is up in public restrooms in the US |
| B．Americans like washing their hands so much |
| C．Adults have their hands washed in public restrooms |
| D．Why hand washing never enjoys popularity in the US |
A couple of years ago, before a trip to China, Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.
“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,” said Davis.
Known as the “Iron Hammer” for her punishing spikes(扣球), Lang made it possible for China to dominate in the sport in the early 1980s. She was a key player on China’s 1984 Olympic gold medal winning team.
When the US team arrived for the Olympics, Lang, 48, who is from Beijing, had to take a different route to avoid a crowd of reporters and fans.
Then came the greatest moment to Lang：while the US team was playing in a packed gym, at least 8,000 Chinese fans unfurled an American flag.
“That really says it all,” Davis said. “They look at her as an icon(偶像)．I’m sure it’s hard for them to see her coaching another country, but they love her so deeply that her success is their success.”
The loyalty of the Chinese fans was tested on Friday, when China lost a match to the US.
“It’s a pity that China lost the match, but I’m still glad that Lang Ping’s team won, since she is the pride of China’s volleyball,” said Liu Chengli, a spectator. “We also cheered for Lang’s victory.”
Lang said she just tried to stay professional when the two teams meet. “It doesn’t matter if we play China or any other team. It’s the same.” Lang said.
Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players, said a US volleyball player Lindsey Berg.
“It’s such an honor to be here and play for our coach here in China,” she said. “The amount of support that the Chinese give to her and us has been tremendous. The whole event has been unbelievable.”What’s the passage mainly about?
| A．Staying professional. | B．Cheering for the Iron Hammer. |
| C．A match between China and the US. | D．Lang Ping’s career as a coach. |
Lang Ping avoided meeting the reporters and fans probably because she ________.
| A．was afraid to be questioned about her strategy |
| B．didn’t want to be paid much attention to |
| C．disliked to be with her fans |
| D．didn’t want to disturb public order |
What does the underlined word “unfurled” exactly mean?
| A．destroyed completely | B．tore into pieces |
| C．spread out to the wind | D．rolled up |
What does Lang Ping mean by saying “It doesn’t matter if we play China or any other team.”？
| A．American Volleyball Team will beat any team. |
| B．Chinese Volleyball Team is the same as other teams. |
| C．She just tried to stay professional. |
| D．The results of each match will be the same. |
What impressed the US team players most?

Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.Paying students who show improvement in tests __________.
| A．has been done in most American schools |
| B．is becoming a growing practice in the USA |
| C．is not very popular with teachers |
| D．only aims at high scores at school |
According to the text, Robert Schaefer _____________.
| A．is a very excellent teacher |
| B．thinks highly of paying students |
| C．thinks students will show improvement in study in the future |
| D．thinks people should make a careful plan for the paying program |
From the last paragraph we can see __________.
| A．EBCWRU has got great success in its paying program |
| B．not all the students in EUCWRU have made progress in all subjects |
| C．only students who study math can get paid |
| D．EBCWRU will go on with the paying program |
The text is mainly written to _____________.
| A．persuade teachers to give students more prizes |
| B．tell people how to become an excellent student |
| C．introduce something about American paying students program |
| D．explain the advantages of American paying students program |
Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.
A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.
One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.
The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).What’s the main idea of the first paragraph?
| A．Explaining why there is a lack of rain at times. |
| B．Introducing several different patterns of rainfall. |
| C．Telling us how to avoid problems caused by rain. |
| D．Giving the idea that there are ways to manage rain water. |
According to the second paragraph, “Rain Gardens" are likely to _____.
| A．harm the environment in the short run |
| B．become popular over the next few years |
| C．be turned down by most new developments |
| D．be too expensive for common people to accept |
We can learn from the third paragraph that _____.
| A．floods are often the results of small rains |
| B．a heavy rain is less difficult for plants to absorb |
| C．the rain garden helps send rainwater back into the air |
| D．larger amounts of rainwater flow straight off in city environments |
According to the last paragraph, what does the rain garden help to clean?
| A．The plants | B．The ground. | C．The water. | D．The street. |
As Apple tries to maintain its growth and success in China, the world's largest smart-phone market is becoming even more critical. Apple's shares(股份) fell sharply as the company's earnings for the holiday quarter through December disappointed investors.
The sales of the iPhone, which include both the iPhone 5 and older models, came in at the low end of analysts' expectations, while the company's income plan for the second quarter was below analysts' forecasts, though Apple is known to give conservative (保守的) forecasts.
Some analysts have said that for Apple to regain its growth, the company needs a more aggressive strategy(进攻型策略) for markets, or more specifically for China, where the market for smart phones has been expanding more rapidly than anywhere else. In China, demand is particularly great for inexpensive phones that run on Android(安卓) operating system, sold by many Chinese phone makers as well as South Korea's Samsung Electronics Co.
But Apple says it's already enjoying strong growth in China. "We saw big growth in iPhones," Chief Executive Tim Cook said. He said that the company has been quickly expanding its sales channels in China, including the number of Apple stores. "This isn't nearly what we need, we're not even close to that, but we're making great progress.” he said.
In China, a big missing piece for Apple is China Mobile Ltd. , the biggest local telecom carrier that doesn't yet sell the iPhone. Earlier this month, Mr. Cook met China Mobile Chairman Xi Guohua in Beijing and discussed cooperation, stirring hopes that the world's largest mobile carrier may soon start offering the iPhone.
Earlier this month, the Wall Street Journal reported that Apple is working on a lower-end iPhone that could launch as early as this year. But one possible challenge for Apple in China is that low-priced Android-based phones are getting better in terms of quality. A report from CLSA in late November showed that many smart-phones sold at about1,000 yuan ($160) came with higher- resolution screens, better cameras and more powerful processors than phones at that price did a year earlier.Apple's shares dropped sharply because in December______________.
| A．the iPhone wasn't popular in China |
| B．its product quality was widely criticized |
| C．the earnings for the holiday quarter was disappointing |
| D．the investors were not satisfied with Apple's management |
What can we learn from the passage?
| A．Apple tends to offer a lower sales forecast. |
| B．China Mobile Ltd began to team up with Apple. |
| C．Cook is pessimistic about what Apple did in China. |
| D．Apple didn't take measures to develop Chinese market. |
The author uses the report from CLSA to prove _____.
| A．their prices are actually lower than a year earlier |
| B．Apple in China has ability to deal with any problem |
| C．low-ended Android-based phones are progressing fast |
| D．the promotion of lower-end iPhone will face a challenge |
The main purpose of the passage is to show the readers ______________.
| A．Apple's high popularity in China |
| B．the challenge Apple faces in China |
| C．the approaching failure Apple will suffer in China |
| D．Apple's aggressive strategy in its market expansion |
Dave Bruno works as an online marketing manager. Several years ago, one weekend Bruno and his family did a major house cleanup and then donated several bags of unneeded items to the local Goodwill store. “After all were done, I looked around and realized that I still had too much stuff”, says Bruno, “It occurred to me that maybe I wanted to lead a simple life but in reality I behaved differently.” That realization prompted the 39-year-old father of three to try an experiment, “The 100Thing Challenge”.
With the goal of breaking free of what he calls a “bad habit of consumerism（消费主义）, Bruno was determined to live for one year with just 100 personal items. He cut down his possessions to 94 items, including a Bible, laptop, guitar, wedding ring, car and clothes. He created some guidelines for the experiment since his wife and daughters did not participate, familyshared and household items did not count as personal items. He also grouped together some basic things such as underwear and socks. Bruno began blogging about his new lifestyle and eventually wrote a book, The 100 Thing Challenge: How I Got Rid of Almost Everything, Remade My Life, and Regained My Soul.
Since completing the experiment, Bruno has continued to live by the motto: reduce, refuse, and rearrange and maintains just 110 personal things. “ Nearly three years of living with a minimal amount of personal possessions, I’m no longer in the habit of consuming for the sake of consumption (消费),” he wrote in his blog last week, “That has freed me up for all sorts of better endeavors (活动) than shopping—like spending time with family and writing a book and planning for business opportunities.”
Bruno’s project has also inspired others to live minimally, many of whom post their own 100 Thing Challenge updates on YouTube. “The reality is that the 100 Thing Challenge is surprisinglyeasy”, says Bruno, “I’m not saying there were no challenges or disappointments. I miss some things, but not that much. Frankly, it’s far easier to live with less stuff than with excessive trash.”What does the underlined sentence mean in Paragraph 1?
| A．Bruno regretted to have an easy life. |
| B．Bruno had a special behavior in reality, |
| C．Bruno and his family led a happy life. |
| D．Bruno would have liked a life with fewer items. |
The things were included in Bruno’s 94 items EXCEPT____________.
| A．socks | B．a Bible | C．cookers | D．a wedding ring |
What is the best title for the passage?
| A．Live with 100 Things |
| B．Defeat 100 Challenges in Life |
| C．Survive by Your Motto |
| D．Consume for Consumption’s Sake |

In a generous display of maturity and sympathy, one Jewish boy made his first deed as a man in his faith a great act of charity.
Joshua Neidorf, a 13-year-old boy from Los Angeles, donated most of his birthday money to Operation Mend, a program that reconstructs the faces of severely burned U. S. veterans（退伍老兵）.
The young man decided to donate his money after getting to know Army Sgt. Louis Dahlman, who was undergoing a series of reconstruction surgeries（手术）at UCLA （University of California at Los Angeles） thanks to Operation Mend. The Neidorfs had signed up to be Dahlman’s “buddy family”, spending time with him whenever he visited Los Angeles for a surgery.
“I just love knowing that it’s going somewhere...to help the people who save our lives and keep us safe every day,” said Neidorf. His mother added, “It makes me feel like our world is going in a good direction with this next generation.”
In all, Neidorf gave $13,000 to Operation Mend. He also encouraged his friends to donate to the cause. He is the organization’s youngest donor so far.
Operation Mend is a privately funded program that works in partnership with the UCLA Medical Center. Ron Katz, a board member at the hospital, started the program in 2006 after seeing a TV programme about Aaron Mankin, a veteran who had gone through dozens of surgeries after a fight in Iraq which completely burned off his face.
Mankin ended up being Operation Mend’s first patient, starting the first of 20 reconstructive facial surgeries at UCLA in Sept. 2007. In a 2011 interview, Katz shared how his experience of helping Mankin made him realize the need to establish a more permanent program.
“My wife and I soon realized that there were dozens of Aarons out there,” Katz said. “They deserve the best that we offer them.”Neidorf decided to help veterans because ________.
| A．he benefited from Operation Mend | B．he was afraid of burned faces |
| C．he thought they deserved help | D．he didn’t know how to spend money |

Two magazines recently listed the best cities to live in. Here are two of the cities listed as “the world’s best.”
SAN JOSE, COSTA RICA The city has comfortable weather all year round (15°C to 26°C ). Housing is not very expensive in San Jose. Also, many of the city’s older neighborhoods are very beautiful and have small hotels and cafés(咖啡馆). Beautiful mountains are around the city. You can visit them easily from San Jose. So lots of people go sightseeing there every year. But air pollution is a problem in the city center.
HONG KONG, CHINA This lively city—once a small fishing village—is today an international business center. It is an interesting mixof East and West, old and new.

Dickson Despommier, a public health professor at Columbia University in New York City developed an idea with his students nine years ago. They imagined people in cities growing crops inside a tall building. Tomatoes could grow on one floor of the skyscraper(摩天大楼), potatoes on the next, small animals and fish on the floor above.
This vertical(垂直的) farm, or "farmscraper", could have space for restaurants and other places that serve food, like schools or hospitals. They could serve foods that are truly locally grown.
But why would anyone want to build a farm indoors in a city? Dickson Despommier believes it will become necessary. The world needs to find places to produce enough food to feed the growing population. Space, he says, is an all-important issue.
The professor also points to the problems of traditional farms. They use a lot of freshwater. Their fertilizer and animal waste can pollute water resources. And their growing seasons can be limited.
But inside the vertical farm, crops could grow all year. And there would be no wind to blow away soil. Farmers would not have to worry about too much or too little rain, or about hot summers, freezing winters or insects. And without insects there would be no need for chemicals to kill them.
Farm machines that .use fossil fuels, like tractors, would not be needed either. And water could be recycled for drinking. "The vertical farm reuses everything, so there is no waste," says Professor Despommier.
Even buildings could be saved. Old buildings could become new farms and provide jobs.
The professor has been actively proposing the idea to cities as far away as Dubai and Canada. But so far it exists only in plans and drawings, and a model at the Museum of Science and Industry in Chicago.
Critics say building a farmscraper would cost too much, especially considering the price of land in many cities. Dickson Despommier estimates the cost at about twenty to thirty million dollars.
But he says the building would not have to be very tall. And his graduate students have found many empty lots and unused buildings in New York City that could provide space.According to the passage the purpose of proposing the idea of a farm scraper is to .

Special Bridges Help Animals Cross the Road
—Reported by Sheila Carrick
Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear (灰熊) and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Ecopassages ” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These ecopassages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lions used the passage.
Builders of ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders (火蜥蜴) and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass!The writer uses the example of “ocelots” to show that _______.
| A．wild animals have become more dangerous |
| B．the driving conditions have improved greatly |
| C．the measure for protecting wildlife fails to work |
| D．an increasing number of animals are killed in road accidents |
From the news story, we know an ecopassage is ________.
| A．an underground path for cars |
| B．a fence built for the safety of the area |
| C．a bridge for animals to get over a river |
| D．a path for animals to cross the road |
When the writer says that animals seem “to be catching on”, he means ________.
| A．animals begin to realize the dangers on the road |
| B．animals begin to learn to use ecopassages |
| C．animals are crossing the road in groups |
| D．animals are increasing in number |
The writer asks visitors and drivers to look around when traveling because ________.
| A．wild animals may attack cars |
| B．wild animals may block the road |
| C．they may see wild animals in the park |
| D．they may see wild animals on ecopassages |
In the UK, a group of campaigners(活动家)have declared the last Saturday in November as National Buy Nothing Day. “Our message is clear: shop less, live more!” says organizer Michael Smith. “The challenge is to try simple living for a day. Spend time with family and friends, rather than spending money on them. Anyone can take part, provided they spend a day without spending.”
On Buy Nothing Day, they take to the streets to tackle consumers(消费者). They dress as pigs to symbolize greed(贪婪). They offer to cut up credit cards and hand out shopping bags with the words “another useless thing I don’t need” written on the side. Some hold street parties to show shoppers that it is possible to have fun without spending money. Others go into shops and put notes saying “don’t buy me” inside clothes and shoes.
Some protestors(抗议者) are working against powerful forces. Many retailers(零售商) and manufacturers depend on Christmas sales for most of their profits. Around two thirds of GDP in the West is made up of consumer spending. If this drops, many people will lose their jobs. At least that will make it easier for them to buy nothing.
And there is also the risk that the campaigners will be seen as killjoys, who want to stop people enjoying themselves. “There’s a fun side to this,” says Michael Smith. “To some it’s a protest, but it’s also a street party. We’re not saying that people are bad because they go shopping, but we need get the message across for people to consume wisely. And after we’re finished, we’ll probably go for a drink.”Why do a group of people in the UK choose Saturday as National Buy Nothing Day?
| A．Because they have enough food at their homes. |
| B．Because it is the season for shopping. |
| C．Because they have run out of money at that time. |
| D．Because it’s popular to live a simple life. |
In order to persuade people to stop shopping, the campaigners _____.
| A．stop people going out |
| B．have different ways to make it |
| C．offer goods to people freely |
| D．play tricks on consumers |
The underlined word “killjoys” in the last paragraph refers to people who _____.
| A．ruin the happiness and fun of others |
| B．get money from shopkeepers |
| C．bring happiness to others |
| D．take no interest in shopping |
The campaigners started National Buy Nothing Day for the purpose of _____.
| A．persuading people to kill time in a different way |
| B．persuading people to save money |
| C．persuading people to have more parties |
| D．persuading people to spend money wisely |
