There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles（肌肉）. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen（氧气）we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.

Officials in a remote Russian city have drawn up a list of practical tips for locals on how to survive encounters (相遇) with bears, after growing numbers have wandered into the streets in search of food.
Officials in the city of Syktyvkar drew up the guidelines to guide the local people, after several bears were caught sight of in the city, going hungry after a heat wave shriveled their usual diet of nuts and berries.
The guide warns that city people there should stay calm and stand still if they meet with a bear. “Speak to the bear in a firm voice” and “Don’t turn your back on it,” it adds. In the worst case, if the bear attacks, the person should also be ready to attack, the guide says. “Shout angrily at it and look it straight in the eye,” the guide advises. “Bears have started coming into the areas where people live more and more often,” the city officials said in a statement. “Any encounter with a bear is unsafe for humans, so our task is to do all we can to prevent such accidents.”
In September, a bear attacked a 25-year-old man in a central street of the city, wounding him in the neck before he managed to run away, police said. “Three or four people who met with brown bears have been recorded recently,” the head of the hunting department in the regional agriculture organization, Alexander said.
Officials have asked police to patrol (巡逻) streets close to wooded areas in the evenings.

| C．get along well with bears | D．drive hungry bears away |
The underlined word “shriveled” in Paragraph 2 probably means _____.

Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned．Sites such as Facebook, Twitter and Bebo are said to shorten attention spans （幅度）, encourage instant satisfaction and make children more self-centered．
Warnings from neuroscientist （神经系统科学家） Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day．But they will strike a chord （弦） with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens．
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts．A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves．But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good．
Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain．Computer games and fast-paced TV shows were also a factor, she said．"My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment．" "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said．
Psychologists have also argued that digital technology is changing the way we think．They point out that students no longer need to plan their term papers before starting to write—thanks to word processors they can edit as they go along．
A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen．Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven．Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning．
Sue Palmer, author of Toxic Childhood, said: "We are seeing children's brain development damaged because they don't engage in the activity they have engaged in for thousands of years．I'm not against technology and computers．But before they start social networking, they need to learn to make real relationships with people．"According to the passage, social networking websites might _____．
| A．make young users more selfish |
| B．lengthen young users' attention span |
| C．encourage young users constant satisfaction |
| D．help young users communicate better with their families |
A neuroscientist may worry that sites like Facebook may ______．
| A．help children learn to make real relationships with people in society |
| B．encourage students not to plan their term papers before starting to write |
| C．disturb those whose social lives depend on surfing their favorite websites |
| D．make real conversation in real time give way to easier and faster screen dialogue |
From the passage we can infer that _____
| A．Baroness Tarot agrees websites cause small children's small attention span |
| B．Jane Healy believes computer games can do good to children's reasoning |
| C．Susan Greenfield's warnings have been brought to wide public attention |
| D．Sue Palmer's book Toxic Childhood discusses the development of networking |

Grandpa Nybakken loved life—especially when he could play a trick on somebody. At those times, his large Norwegian frame shook with laughter while he pretended innocent surprise, exclaiming, “Oh, forevermore!” But on a cold Saturday in downtown Chicago, Grandpa felt that God played a trick on him, and grandpa wasn’t laughing.
Grandpa worked as a carpenter. On this particular day, he was building some boxes for the clothes his church was sending to an orphanage abroad. On his way home, he reached into his shirt pocket to find his glasses, but they were gone. He remembered putting them there that morning, so he drove back to the church．His search proved fruitless.
Suddenly, he realized what had happened. The glasses had slipped out of his pocket unnoticed and fallen into one of the boxes, which he had nailed shut. His brand new glasses were heading for China!
The Great Depression was at its height, and Grandpa had six children. He had spent twenty dollars for those glasses that very morning.
“It’s not fair,” he told God as he drove home in frustration. “I’ve been very faithful in giving of my time and money to your work, and now this.”
Several months later, the director of the orphanage was on vacation in the United States．He wanted to visit all the churches that supported him, so he came to speak on Sunday night at my grandfather’s small church in Chicago．Grandpa and his family sat in their usual seats among the small congregation（教堂会众）.
“But most of all,” he said, “I must thank you for the glasses you sent last year.”
“Even if I had the money, there was simply no way of replacing those glasses．Along with not being able to see well, I experienced headaches every day, so my co-workers and I were much in prayer about this．Then your boxes arrived．When my staff removed the covers, they found a pair of glasses lying on the top.” After a long pause, he continued, “Folks, when I tried on the glasses, it was as though they had been custom-made just for me! I want to thank you for being a part of that!”
The people listened, happy for the amazing glasses．But the director surely must have confused their church with another, they thought, there were no glasses on their list of items to be sent overseas.
But sitting quietly in the back, with tears streaming down his face, an ordinary carpenter realized the Master Carpenter had used him in an extraordinary way.Which of the following is NOT true about Grandpa Nybakken according to the passage?
| A．He was an outgoing man and held an active attitude towards life. |
| B．He had a large family to support. |
| C．He was a carpenter working in the church |
| D．He was a loyal Christian. |
The people in the church but Grandpa felt confused at what the director said because ________.
| A．Grandpa didn’t tell the director that he was the owner of the glasses |
| B．the director wanted to return the glasses even though he liked it |
| C．the director could not get such glasses in their own country |
| D．the glasses were not included in the donation list |
Who does “the Master Carpenter” in the last paragraph probably refer to?
| A．Grandpa’s master． | B．One of Grandpa’s friends． |
| C．Grandpa’s co-worker. | D．God． |
Which can be the best title of the passage?
| A．Grandfather’s life | B．The Helpful Donation |
