A New Strategy to Overcome Breast Cancer Post-menopausal(绝经后的)women who walk for an hour a day can cut their chance of breast cancer significantly, a study has suggested. The report, which followed 73 , 000 women for 17 years, found walking for at least seven hours a week lowered the risk of the disease. The American Cancer Society team said this was the first time reduced risk was specifically linked to walking. UK experts said it was more evidence that lifestyle influenced cancer risk. A recent poll for the charity Ramblers found a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers. This study, published in Cancer Epidemiology, Biomarkers & Prevention, followed 73, 615 women out of 97, 785 aged 50 -74 who had been recruited by the American Cancer Society between 1992 and 1993, so it could monitor the incidence of cancer in the group. They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking, swimming and aerobics(有氧运动)and how much time they spent sitting watching television or reading. They completed the same questionnaires at two-year intervals between 1997 and 2009. Of the women, 47% said walking was their only recreational activity. Those who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those who walked three or fewer hours per week. Dr. Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta, Georgia, who led the study, said, “Given that more than 60% of women report some daily walking, promoting walking as a healthy leisure-time activity, could be an effective strategy for increasing physical activity amongst post-menopausal women. We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women. “ “More strenuous(紧张的)and longer activities lowered the risk even more. “ Baroness Delyth Morgan, chief executive of Breast Cancer Campaign, said, “ This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer, and even small changes incorporated into our normal day-to-day activity can make a difference. “ She added, “We know that the best weapon to overcome breast cancer is’the ability to stop it occurring in the first place. The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer. “

When Our Words Collide “Wanna buy a body?“ That was the opening line of more than a few phone calls I got from freelance(自由职业)photographers when I was a photo editor at U. S. News. Like many in the mainstream press, I wanted to separate the world of photographers into “ them“ , who trade in pictures of bodies or chase celebrities, and ’’us“ , the serious news people. But after 16 years in that role, I came to wonder whether the two worlds were easily distinguishable. Working in the reputable world of journalism, I assigned photographers to cover other people ’ s nightmares. I justified invading moments of grief, under the guise(借口)of the reader’ s right to know. I didn’ t ask photographers to trespass(冒犯)or to stalk(跟踪), but I didn’ t have to. 1 worked with pros(同行)who did what others did, talking their way into situations or shooting from behind police lines to get pictures I was after. And I wasn’ t alone. In the aftermath of a car crash or some other hideous incident when ordinary people are hurt or killed, you rarely see photographers pushing past rescue workers to capture the blood and gore(血腥场面). But you are likely to see local newspaper and television photographers on the scene—and fast. How can we justify our behavior? Journalists are taught to separate doing the job from worrying about the consequence of publishing what they record. Repeatedly, they are reminded of a news-business dictum(格言): leave your conscience in the office. You get the picture of the footage; the decision whether to print or air it comes later. A victim may lie bleeding, unconscious, or dead;your job is to record the image. You put away your emotions and document the scene. We act this way partly because we know that the pictures can have important meaning. Photographs can change deplorable(凄惨的)situations by mobilizing public outrage or increase public understanding. However, disastrous events often bring out the worst in photographers and photo editors. In the first minutes and hours after a disaster occurs, photo agencies buy pictures. Often an agency buys a picture from a local newspaper or an amateur photographer and put it up for bid by major magazines. The most keenly sought “exclusives“ command tens of thousands of dollars through bidding contests. Many people believe that journalists need to change the way they do things, and it’ s our pictures that annoy people the most. Readers may not believe, as we do, that there is a distinction between sober-minded us and sleazy(低级庸俗的)“them“. In too many cases, by our choices of images as well as how we get them, we prove our readers right.

The Storyteller 1 Steven Spielberg has always had one goal: to tell as many interesting stories to as many people as possible. The son of a computer scientist and a pianist, Spielberg spent his early childhood in New Jersey and then Arizona. Some of his childhood memories became the inspiration for his filmmaking. 2 Even decades later, Spielberg says he has vivid memories of his earliest years, which are the origins of some of his most successful films. He believes that E. T. is the result of the difficult years leading up to his parent s 1966 divorce. He commented, “ It is really about a young boy who was in search of some stability in his life. “ Close Encounters of the Third Kind was inspired by times when the four-year-old Steven and his father would search the skies for meteors(流星). His mother remembers, “ He was scared of just about everything. When trees brushed against the house, he would jump into my bad. And that’ s just the kind of scary stuff he would put in films like Poltergeist. “ 3 Spielberg was 11 when he first got his hands on his dad’ s movie camera and began shooting short flicks(电影)about flying saucers(飞碟)and World War TJ battles. These homemade movies gave him a way to escape his fears. From the very beginning, he had a creative imagination. With his talent for scary storytelling, he could terrify his three younger sisters. It also made it easier for him to make friendships. On Boy Scout camping trips, when night fell, young Steven became the center of attention. “ Steven would start telling his ghost stories, “says Richard Y. Hoffman. Jr. , leader of Troop 294, “and everyone would suddenly get quiet so that they could all hear. “ 4 Spielberg moved to California with his father and went to high school there, but his grades were so bad that he barely graduated. Both UCLA and USC film schools rejected him, so he entered California State University at Long Beach because it was close to Hollywood. Spielberg was determined to make movies, and he managed to get an unpaid, non-credit internship(实习)in Hollywood. Soon he was given a contract, and he dropped out of college. He never looked back. 5 Now, many years later, Spielberg is still telling stories with as much passion as when he was a boy. Ask him where he gets his ideas, and Spielberg will shrug. “The process for me is mostly intuitive, “ he says. “There are films that I feel that I need to make. And it’ s for a variety of reasons, for personal reasons, or because I just want to have fun. Or maybe because the subject matter is cool, and I think that my kids will like it. “ A.

How We Form First Impression We all have first impression of someone we just met. But why? Why do we form an opinion about someone without really knowing anything about him or her—aside perhaps from a few remarks or readily observable traits? The answer is related to how your brain allows you to be aware of the world. Your brain is so sensitive in picking up facial traits. Even very minor difference in how a person’ s eyes, ears, nose, or mouth are placed in relation to each other makes you see him or her as different. In fact, your brain continuously processes incoming sensory information—the sights and sounds of your world. These incoming signals are compared against a host of “memories “stored in the brain areas called the cortex(皮质)system to determine what these new signals “mean“. If you see someone you know and like at school, your brain says “ familiar and safe“. If you see someone new it says, “new and potentially threatening“. Then your brain starts to match features of this stranger with other ““known“memories. The height, weight, dress, ethnicity, gestures, and tone of voice are all matched up. The more unfamiliar the characteristics are, the more your brain may say, “This is new, I don’t like this person“. Or else, “!’ m intrigued(好奇的)“. Or your brain may perceive a new face but familiar clothes, ethnicity, gestures—like your other friends; so your brain says, “I like this person“. But these preliminary “impressions“can be dead wrong. When we stereotype people, we use a less mature form of thinking(not unlike the immature thinking of a very young child)that makes simplistic and categorical impressions of others. Rather than learn about the depth and breadth of people—their history, interest values, strengths, and true character—we categorize them as jocks(骗子), peeks(反常的人), or freaks(怪人). However, if we resist initial stereotypical impressions, we have a chance to be aware of what a person is truly like. If we spend time with a person, hear about his or her life, hopes, dreams, and become aware of the person’ s character, we use a different, more mature style of thinking—and the most complex areas of our cortex, which allow us to be humane.

Wrongly Convicted Man and His Accuser Tell Their Story NEW YORK, NY, January 5, 2010. St. Martin’ s Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “ account of violence, rage, redemption(救赎), and ultimately forgiveness. “ The story began in 1987, in Burlington, North Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally. 【B1】______When the police asked her if she could identify the assailant(袭击者)from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup. Based on her convincing eyewitness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cotton’ s lawyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole. 【B2】______Jennifer Thompson looked at both men face to face, and once again said that Ronald Cotton was the one who raped her. Eleven years later, DNA evidence completely exonerated(证明......清白)Cotton and just as unequivocally (明确地)convicted Poole, who confessed to the crime.【B3】______“The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, who hurt me, who took my spirit away, who robbed me of my soul, “ she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent. “ 【B4】______Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which they have subtitled “Our memoir of injustice and redemption“. Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly, 【B5】______“ A. Jennifer Thompson decided to meet Cotton and apologize to him personally. B. Many criminals are sent to prison on the basis of accurate testimony by eyewitnesses. C. I cannot begin to imagine what would have happened had my mistaken identification occurred in a capital case. D. Another trial was held. E. Thompson was shocked and devastated. F. During the attack, she made an effort to memorize every detail of his face, looking for scars, tattoos(纹身), or other identifying marks.

US economist Martin Schmidt suggests a tax on fast food【C5】______to people ’ s cars. “ We tax cigarettes partly because of their health cost, “ Schmidt said. “Similarly, leading a lazy lifestyle will end【C6】______costing taxpayers more. US political scientist Eric Oliver said his first instinct was to laugh at these gas and fast food arguments. But such【C7】______are getting attention. At the US Obesity Society’ s annual meeting, one person【C8】______obesity with car accident deaths, and another correlated obesity with suicides. No one asked whether there was really a cause-and-effect relationship. “The funny thing was that everyone took it【C9】______, “ Oliver said. In a 1960s study, children were【C10】______drawings of children with disabilities and without them , and a drawing of an obese child. They were asked【C11】______they would want for a friend? The obese child was picked last. Three researchers recently repeated the study【C12】______college students. Once again, 【C13】______ no one, not even obese people, liked the obese person. But, researchers say, getting【C14】______is not like quitting smoking. People struggle to stop smoking, and, in the end, many succeed. Obesity is different. Science has shown that they have limited personal control over their weight. Genes also【C15】______a part.
