第二部分阅读理解（满分40分）阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
21．（6分）It’s truly amazing when we get to cover news of people who single-handedly create something truly significant. Jadav Payeng, a man in his mid-fifties, has changed a sandbar（沙洲）in the middle of a river in Assam, India, into a huge forest. His work of the past 30 years is being recognized by tourists and
film-makers, the world over.
Mulai, a Jadav is known among locals, started work on the land in 19080. A scheme was launched at that time by the social forestry department of the district, involving the planting of trees on only 200 hectares. The project was completed after 5 years and all the laborers left, except Mulai. Dedicated to the forest, he stayed on and single-handedly looked after the trees, continuing to plant more of them. Eventually, the forest expanded to 550 hectares. This is perhaps the world’s biggest forest in the middle of a river. Mulai says there’s potential to extend this even further to 1,000 hectares. Inspired, the department has planned to launch another plantation program this year.
The forest is named “Mulai Kathoni” by the local people, meaning Mulai’s forest. It is home to several thousands of varieties of trees. Bamboo alone covers about 300 hectares. And it’s not just the plants, there’s wildlife living in there too. There are about four tigers, three rhinos and more than a hundred deer, rabbits and apes. There are innumerable varieties of birds who call this place home, as well. A herd of about 100 elephants visit the place every year for six months.
Mulai lives in a small hut near the forest, with his wife, two sons and a daughter. He makes a living by selling cow and buffalo milk. I suppose people such as Mulai are an inspiration to the entire world. If one man can build a forest, it’s amazing to think what we can achiev e if we work together.
1、Why did Mulai stay in Assam after 1983?
A．To raise his family. B．To plant more trees.
C．To build a home on the sandbar. D．To protect the animals.
2、Which words can best describe Mulai according to paragraph 2?
A．Wise, far-sighted. B．Lucky, creative
C．Devoted, ambitious. D．Modest, easy-going.
3、What may be the best title for the text?
A．Wildlife in Mulai’s Forest
B．India Starts a Plantation Program
C．More Efforts to Protect Our Forests.
D．Indian Man Plants a Whole Forest Alone.
22．（8分）For months fish that live in dark caves in Mexico go without food. They have gone far longer- thousands of years-without light, evolving to lose their eyes and skin pigments（色素）.Now researchers have discovered these strange creatures have another oddity. They survive their food-scarce environment, the fish have evolved extreme ways of turning nutrients into energy. These features create symptoms like large blood sugar swings that, in humans, are predictors of type 2 diabetes. But in the fish these changes are adaptations, not a disease. These cave fish lead log and healthy lives.
Understanding how the fish remain healthy in spite of these symptoms may lead to new approaches for treating diabetes in people, says Cliff Tabin, a geneticist at Harvard Medical School. He and his colleagues are beginning to get clues about how cave fish survive the symptoms.
In humans and other mammals, one of the first signs of type 2 diabetes risk is poor control of Wood sugar (glucose). This happens because cells resist insulin, the hormone that signals cells to take in glucose from the bloodstream. If the problems continue, they progress into full-blown diabetes. The illness kills 3.4 million people worldwide every year, but current treatments often do not work.
The cave fish has, apparently, figured out another solution. The fish were washed from rivers into caves about a million years ago. It was a big change. Rivers were full of food but caves have only what is washed in by seasonal floods.
Because cave fish go many months without food, researchers assumed they evolved a metabolism(新陈代谢）that efficiently stores the calories in a similar way animals store fat before winter. To test that idea, they compared the cave fish with the river fish raised under same conditions in the lab. They found the cave fish do store more visceral fat than river fish. But the cave fish also had much larger, fatty livers, which resembled diabetes-linked fatty liver disease in humans. “But you don’t see destruction of the liver in these guys.” Tabin says. “It’s very curious.”
Cave fish researchers are now working to find out how the fish do it. “The only piece of total evidence is that the metabolic rate is lower in the cave fish than in their river fish relatives.” says Alex Keene of Florida Atlantic University. "There might be something about slow energy use in cells that protects against diabetes." he says, “Finding that something will, like fishing, require some patience.”
1、What interests researchers most in the cave fish is that .
A．they have evolved to lose their eyes and skin pigments
B．they have evolved ways of turning nutrients into energy
C．they have experienced no symptoms of diabetes in humans
D．they have survived from symptoms of diabetes in humans
2、It can be learned from Paragraph 3 that .
A．insulin disturbs the control of blood sugar
B．insulin takes in glucose from the bloodstream
C．insulin prevents the rise of blood sugar
D．insulin lends to progress into full-blown diabetes
3、Researchers study the metabolism in the cave fish mainly by .
A．testing the efficiency of storing fat inside them
B．comparing their fat amount with that in the river fish
C．comparing their fatty livers with those of humans
D．observing their livers storing fat with no destruction
4、It can be concluded that the features of the cave fish .
A．have enabled researchers to find out new ways to treat diabetes
B．have inspired researchers about new treatments for diabetes
C．have brought in many new ideas about how to treat diabetes
D．will be used as a treatment for diabetes in the near future
23．（8分）Formal Afternoon Teas
A pot of tea, a plate of finger sandwiches and a selection of pastries and scones: In America, this wonderful way to w ile away the afternoon is commonly, though mistakenly, known as “high tea.” In Britain, where it originated, “high tea” is simply an old-fashioned name for the evening meal; it’s also called “meal tea.” The light, elegant, scone-centric meal served at fanc y hotels is called “low tea” or “afternoon tea”.

When she was thirteen, she was surfing the Internet on a regular basis, but she couldn't find anywhere for teenagers to meet and talk. And one day she thought, "If I had my own website, I'd make it a really interesting site for teenagers."
Consequently, when Ashley was sixteen, she started her own website called GooseHead. She had no idea how big a success it would be, but three years later, the site was the most successful teen site in the USA! It was getting 100,000 hits every day, and Ashley had about 30 employees.
After a few years, the website closed down. Then Ashley, who lived in Los Angeles, was asked to write a book called The GooseHead Guide to Life. The book is about how to design a website and start a business.
It begins with a section called"All About Ashley", where Ashley tell readers what it's like to be the boss of a company when you' re only sixteen—not always easy!
In her book, Ashley talks about the problems that teenagers have today plus the importance of friendship. She also focuses on being independent. "Learn to love your friends but not rely on them. I did that by creating GooseHead on my own."
Ashley says that The GooseHead Guide to Life is not a book of teenage advice."It isn't a book that's going to tell you what to do. I hope you can work that out yourself," she says."I just want to provide a little inspiration to teenagers. Maybe after reading my story, you'll start your own website! But perhaps you' ve got a better idea? Well, if I were you, I'd just do it, whatever it is. Maybe it won't work—but maybe it will."
1、Why did Ashley start GooseHead?
A．To promote the sale of her book.
B．To update her mother's computer.
C．To teach teenagers how to use the Internet.
D．To create a platform for teenagers to communicate.
2、Where can you find the information that best shows the success of Ashley’s website?
A．In Paragraph 1. B．In Paragraph 2. C．In Paragraph 3. D．In Paragraph 4.
3、What do we know about The GooseHead Guide to Life?
A．It serves to fuel teenagers' motivation.
B．It is meant to give teenagers tips.
C．It advises teenagers to depend on friends.
D．It is about ways to be boss of a company.
4、What does Ashley inspire teenagers to do？
A．Follow their dream.
B．Start their own website.
C．Buy a copy of her book.
D．Be a model for others.
25．（10分）In China，chain restaurants especially the big multinational ones are cool．Going to Starbucks，for example，is a status symbol．It not only says，"I'm rich enough to buy this overpriced coffee，"but also，"I'm cosmopolitan （见多识广的）enough to be part of globalization．"
Where I come from in the UK，however，chains are neither fashionable nor gourmet（美食的）．Chains are where you go on New Y ear's Day when nowhere else is open，or when you are 5 years old and your parents can't stand hearing，"I'm hungry!"any longer．In my own case （with regards to McDonald's），a chain is where you are taken on your first"date"．Even at the age of 13，I knew to give the guy the"let's just be friends"phone call the next day．
In the UK，independent cafes and restaurants are making a comeback on the fashion scene．Nowadays，a Londoner who says"let's meet for a coffee at Monmouth"（an independent cafe）is much cooler than one who says"let's go to Starbucks"．Even if Monmouth's coffee is a little more expensive，there's a satisfaction in knowing your pounds aren't going straight to the big corporations．Of course，there are chain stores all over the UK；you can't go five minutes without spotting a Costa Coffee．But numbers do not add up to good taste．
I do，however，have a confession （坦白）．After moving to China I had moments when all the rice and Kung Pao Chicken became too much．I，too，have retreated to McDonald's．
1、Many Chinese people like to go to multinational chain restaurants because ______ ．
A．the restaurants give customers a taste of foreign culture
B．the restaurants offer different food and drinks from other restaurants
C．they believe that eating there will show their wealth and social status
D．these restaurants are perfect places for a romantic date
2、Which of the following statements is TRUE？______
A．The author has grown tired of Chinese food．
B．Branches of Monmouth's cafe can be found all over the UK．
C．Most independent stores are closed on New Year's Day in the UK．
D．It is cool in the UK to take your first date to a chain restaurant．
3、We can infer from the article that ______ ．
A．the author doesn't like food from Pizza Hut
B．the author doesn't like to follow fashion trends
C．many Britons think that numbers mean poor quality
D．many Britons don't like big corporations
