Some weightloss camps, which are rare in China just a few years ago，have multiplied in Beijing, Qingdao, Shenzhen，and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these, 90 million—about 7 percent—are obese(极肥胖的)．
Experts say the obesity epidemic(流行病) is spreading to children, though more slowly than in adults. The obesity, they say, will do harm to the health of China’ s citizens and economy.“We're seeing a very large number of teenagers who are quite heavy and aren't moving much，” said Barry Popkin, a nutrition(营养) professor. Popkin carries out an ongoing healthandnutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight “quite quickly.” In just ten years China‘s childhood obesity rate has doubled，with the greatest gains coming in urban areas.“In big cities it's a big problem.”
Some experts blame the extra fat on a range of factors, many of them tied to China’ s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in meats, fish, eggs, dairy products, fats and sugars than ever before. In addition，kids—especially city dwellers—are more sedentary today and spend more time indoors in front of homework, television，computer games, and the Internet.
Shuwen Ng，a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features.
China’ s childhood obesity rate stillfall behind that of the United States, where some 15 percent of kids are said to be obese. But the longterm effects are equally serious.

What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.
1．Digital money
We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.
You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.
2．Bionic(能力超人的)eye
It's no longer something only in a scifi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.
Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a highresolution(高清晰度的) version could be just a few years away.
3．Selfdriving cars
Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a selfdriving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.
Many vehicle companies are now planning selfdriving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road，” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.
【小题1】The underlined word “distracted” in the article is closest in meaning to “________”．
| A．directed | B．discouraged |
| C．attacked | D．disturbed |
| A．optimistic | B．pessimistic |
| C．doubtful | D．cautious |
| A．Learning Kit | B．Campus Trends |
| C．Entertainment | D．Technology |

IT’S never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of coping with the cold.
But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite (冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits, according to the study. Some plants, such as oak trees, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions of years of evolution. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat of climate change.
【小题1】What is the article mainly about?
| A．Why plants are not afraid of the winter chill. |
| B．The ways that plants survive cold weather. |
| C．Changes in plants’ water transport system in winter. |
| D．How plants evolve to keep up with climate change. |
| A．it produces more living tissues to stay alive |
| B．its leaves quickly fall out and its roots begin to die |
| C．lots of air bubbles form in its water transport system |
| D．its water transport system could be blocked in the spring |
| A．By dropping their leaves before winter. |
| B．By narrowing their water transport cells. |
| C．By widening their water transport cells. |
| D．By leaving only the seeds alive and growing from the seeds in the spring. |
| A．Plants may not be able to adapt to the increasingly cold climate. |
| B．Human activities might have a great impact on the pace of plants’ evolution. |
| C．Plants may not be able to evolve fast enough to adapt to human-caused climate change. |
| D．The strategies plants develop are not good enough to protect them against cold. |

Today just as technology changed the face of industry, farms have undergone an “agricultural revolution”. On the farm of today, machines provide almost all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.
【小题1】According to the passage, computers can NOT help farmers decide _______.
| A．what livestock to raise |
| B．whether to plant a certain kind of crop |
| C．how much money they can earn from their products |
| D．when to sell their products |
| A．Farmers in the future will depend totally on computers. |
| B．Both computers and robots have been in use on today’s farms. |
| C．Farmers mainly use machines on their farms at present. |
| D．Students at agricultural colleges must take computer classes because they can do nothing without the help of computers on today’s farms. |
| A．all farm work | B．milking cows |
| C．most of the farm work | D．some farm work |
| A．Computer, Farmers’ Best Friend |
| B．The Agricultural Revolution |
| C．Farmers in The Future |
| D．Computers and Robots |

A smart phone (智能手机) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (导航) units to form one multi-use device. Many modem smart phones also include touch screens and web browsers (浏览器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
【小题1】People prefer a smart phone to a common one, because the latter only can help us ______.
| A．check emails | B．send messages | C．find the destination | D．watch a video |
| A．devotion | B．contribution | C．addiction | D．emotion |
| A．People spend as average of two hours and 40 minutes each day using smart phones. |
| B．The film hasn’t been put on in the cinema. |
| C．The film is written by an actor named Charlene Deguzman. |
| D．The film has already been viewed more than 105 million times in the first few days. |
| A．encouraged | B．depressed | C．proud | D．satisfied |

The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”. But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?
Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.
The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing (引证) older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your friend who is slow to learn that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays against funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.
In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem (自尊). The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”
Those with low self-esteem didn’t feel better after the forced self-affirmation (自我肯定). In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think of positive thoughts.
The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic viewpoint. Call it the power of negative thinking.
【小题1】The first paragraph is written _________.
| A．to raise an argument about positive thinking |
| B．to introduce the power of positive thinking |
| C．to encourage people to have positive thoughts |
| D．to introduce the $11 billion self-help industry |
| A．positive thinking is not as powerful as negative thinking |
| B．encouraging positive thinking may actually discourage people |
| C．happy people can think positively while unhappy people can’t |
| D．getting people to think positively can strengthen their confidence |
| A．You are pointing out the mistakes he has made. |
| B．You are reminding him that he is not intelligent. |
| C．You are not taking his mistakes seriously enough. |
| D．You are showing he has great potential in spite of faults. |
| A．negative feelings must be got rid of |
| B．there’s no point in thinking positively |
| C．it doesn’t make sense to think negatively |
| D．negative thinking is not always negative |

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
【小题1】The biggest difficulty in operating on the damaged brain is that _______.
| A．the time is too short for doctors |
| B．the patients are often too nervous |
| C．the damage is extremely hard to fix |
| D．the blood-cooling machine might break down |
| A．taking the blood out of the brain |
| B．trying the operation on monkeys first |
| C．having the blood go through a machine |
| D．lowering the brain' s temperature |
| A．can last as long as 30 minutes |
| B．can keep the brain' s blood warm |
| C．can keep the patient' s brain healthy |
| D．can help monkeys do different jobs |
| A．a,b,c,d | B．c,a,b,d | C．c, b, d, a | D．b, c, d, a |

When author Nicholas Carr began researching his book on whether the Internet is ruining our minds，he restricted his online access and email.His new book argues the latest technology renders us less capable of deep thinking.Carr found himself so distracted(分心的) that he couldn’t work on the book while staying as connected.After first feeling confused by his sudden lack of online connection，he was able to stay focused on one task for a long period within several weeks.
Reading on the Internet has changed how we use our brains.Facing a lot of texts，video，music and links to other web pages and blogs，our minds have become used to skimming and scanning information.As a result，we have developed sharper skills at making fast decisions，particularly visual ones，Carr wrote.
But now most of us seldom read books or long articles that would help us focus.We are becoming more like librarians—able to find information quickly and see clearly the best nuggets(有价值的资料)．That lack of focus hinders(阻碍) our longterm memory，leading many of us to feel distracted，he wrote.
“What we are losing is a whole other set of mental skills，which require not the shifting of our focus but the maintaining of our focus，” Carr said，adding that for centuries books protected our brains from distraction and focused our minds on one topic at a time.
But with devices such as Apple’s iPad becoming common，Carr predicts books also will change.“New forms of reading always require new forms of writing，” he said.Carr has a suggestion for those who feel web surfing has left them incapable of concentration—slow down，turn off the Internet and practice the skills of contemplation(沉思) and reflection.“It is pretty clear from the brain science that if you don’t exercise particular cognitive skills，you are going to lose them，” he said.“If you are constantly distracted，you are not going to think in the same way that you would think if you paid attention.”
【小题1】What topic is Nicholas Carr’s new book mainly concentrating on?
| A．Whether there is any need for us to surf the Internet. |
| B．How the Internet changes our way of thinking. |
| C．What we should do when we are surfing the Internet. |
| D．Whether our minds are being influenced by the Internet. |
| A．Anxious. | B．Relaxed. |
| C．Concentrated. | D．Puzzled. |
| A．prevents | B．causes |
| C．protects | D．sharpens |
| A．They should read more books besides surfing the Internet. |
| B．They should often slow down their pace of modern living. |
| C．They should often get away from the disturbing of the Internet. |
| D．They should spend more time thinking while surfing the Internet. |
