The Boy Made It!  One Sunday, Nicholas,a teenager, went skiing at Sugarloaf Mountain in Maine．In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area．Unable to see far,he accidentally turned off the path．Before he knew it,Nicholas was lost,all alone!He didn't have food,water,a phone,or other supplies．He was getting colder by the minute．

    Nicholas had no idea where he was．He tried not to panic．He thought about all of the survival shows he had watched on TV．It was time to put the tips he had learned to use．

    He decided to stop skiing．There was a better chance of someone finding him if he stayed put．The first thing he did was to find shelter from the freezing wind and snow．If he didn't,his body temperature would get very low,which could quickly kill him．

    Using his skis,Nicholas built a snow cave．He gathered a huge mass of snow and dug out a hole in the middle．Then he piled branches on top of himself,like a blanket,to stay as warm as he could．

    By that evening,Nicholas was really hungry．He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water．Not knowing how much longer he could last,Nicholas did the only thing he could—he huddled(蜷缩)in his cave and slept．

    The next day,Nicholas went out to look for help,but he couldn't find anyone．He followed his tracks and returned to the snow cave,because without shelter,he could die that night．On Tuesday,Nicholas went out again to find help．He had walked for about a mile when a volunteer searcher found him．After two days stuck in the snow,Nicholas was saved．

Nicholas might not have survived this snowstorm had it not been for TV．He had often watched Grylls' survival show —-Man vs．Wild． That's where he learned the tips that saved his life．In each episode(一期节目) of Man vs．Wild, Grylls is abandoned in a wild area and has to find his way out．

    When Grylls heard about Nicholas' amazing deeds,he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive．

    Buttons are found on all sorts of clothing. They are usually small and round and made of metal or plastic. They fasten, or connect, one piece of clothing to another. They make sure your clothes don't fall off. When we are speaking or writing m English, buttons can be just as useful.

    Men or women often wear button-down clothes to the office. Button-down as an adjective means to be conservative（保守的）or traditional. People who are described as buttoned-down stay close as possible to the normal way of dressing and behaving. They don't wear crazy clothing or do unusual things. People and events can both be described as buttoned-down.

    If someone is buttoned-up, he or she seems very business-like. In personal relationships, a buttoned-up person is cold and standoffish, meaning they physically and emotionally keep away from others. Buttoned-up people are not warm or friendly. And they do not share their inner thoughts and feelings with others.

    In the expression “button up”, button is a verb. It means to stop talking. Now, let's say you find yourself buttonholed in a conversation at a party. The person just keeps talking and talking and talking! Finally, you can't take it any longer. You tell the person to button it! This is a direct, but unacceptable way of saying “stop talking”. Button you lip is another equally rude but effective to stop a person who talks too much.

    Another kind of difficult person is someone who pushes your buttons. To push someone's buttons means to know exactly how to get that person angry or upset. People who like to push other people s buttons usually do it for selfish reasons. First they find a person's weak point. Then they use it to upset him.

    A latest research led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Hou. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analyzed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we're also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors, "explained Prof Hou.

    Last year marked the 100th anniversary of the end of World War I. There were events around the world in memory of those who died in the conflict. We have picked out three of them inEuropean countries. Let's take a look.

    Belgium

    In a park, the famous Belgian artist Koen Vanmechelen had an exhibition called Coming World, Remember Me. The work consisted of 600,000 individual(个别的) clay sculptures, one for each person killed during the World War. In the center of the exhibition was a big egg made of clay, symbolizing a new world.

    UK

    In a small town called Aldridge, almost 100 houses in one street were covered with 24,000 poppies and statues of soldiers. They stood for the men from the area who had been' killed in the war. The flowers were chosen because of a poem written by the Canadian doctor John McCrea in 1915. They made people think of fields of blood.

    France

    The British artist Guy Denning arrived in La Feuille, a small town in the northwest of France, to stick life-size drawings of soldiers who never came back home. Armed with glue and a brush, Denning stuck his drawings carefully on walls. Before long 112 men, mainly young adults, were brought back to mind, if not to life.

    Did you ever have to say "no" to somebody? Such as a classmate who asks to go to lunch with you? New research suggests that, at least socially, a rejection (拒绝) should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.

    Gili Freedman is doing some related research at Dartmouth College. For her research, she asked over 1,000 people to respond to different examples of social rejection. In one example, the researchers asked people for their reaction (反应）after a person named Taylor asked to join a co-worker who went out to lunch every Friday. And Taylor was told "no". But in some cases, the person rejecting Taylor offered an apology. In other cases, the people doing the rejection did not say they were sorry. People were asked how they would feel if they were being turned down, just as Taylor was. Most said they would be more hurt by a rejection with an apology than a rejection without an apology.

    Freedman said the reason is that apologies make people feel like they need to say that the rejection was okay— even when they felt like it was not okay. Rejection without an apology lets them express their feelings of disappointment, hurt or anger more easily. Freedman also said that an apology often makes the person doing the rejection feel better—even as it makes the person being rejected feel worse.

    Her research deals only with social communication. A business situation might be very different. "If a manager rejects a job interviewee or a boss must tell an employee that he or she is being fired from a job," Freedman said, "reactions to apologies may be different."
