单选题In Sports, Red is the Winning Color When opponents of a game are equally matched, the team dressed in red is more likely to win, according to a new study. British anthropologists Russell Hill and Robert Barton of the University of Durham reached that conclusion by studying the outcomes of one-on-one boxing, tae kwon do, Greco-Roman-wresting, and freestyle-wrestling matches at the 2004 Summer Olympics in Athens, Greece. In each event Olympic staff randomly assigned red or blue clothing or body protection to competitors. When otherwise equally matched with their opponent in fitness and skill, athletes wearing red were more likely to win the bout. "Where there was a large point difference—presumably because one contestant was far superior to the other color had no effect on the outcome," Barton said, "Where there was a small point difference, the effect of color was sufficient to tip the balance." In equally matched bouts, the preponderance of red wins was great enough that it could not he attributed to chance, the anthropologists say. Hill and Barton found similar results in a review of the colors worn at the Euro 2004 international soccer tournament. Their report will be published in tomorrow"s issue of the journal Nature. Joanna Setchell, a primate researcher at the University of Cambridge in England, has found similar results in nature. Her work with the large African monkeys known as mandrills shows that red coloration gives males an advantage when it comes to mating. The finding that red also has an advantage in human sporting events does not surprise her, adding that "the idea of the study is very clever." Hill and Barton got the idea for their study out of a mutual interest in the evolution of sexual signals in primates— "red seems to be the color, across species, that signals male dominance and testosterone levels," Barton said. For example, studies by Setchell, the Cambridge primate researcher, show that dominant male mandrills have increased red coloration in their faces and rumps. Another study by other scientists shows that red plastic rings experimentally placed on the legs of male zebra finches increase the birds" dominance. Barton said he and Hill speculated that there might be a similar effect in humans. And if so, it could be apparent in sporting contests. The pair say their results indicate that sexual selection may have influenced the evolution of humans" response to color. Setchell, the primatologist, agrees. "As Hill and Barton say, humans redden when we are angry and pale when we"re scared. These are very important signals to other individuals," she said. The advantage of red may be intuitively known, judging from the prevalence of red uniforms in sports— "though it is clearly not very widely appreciated, on a conscious level at least," Barton said. He adds that the finding of red"s advantage might have implications for regulations that govern sporting attire. In the Olympic matches he surveyed for the new study, for example, it is possible some medal winners may have reached the pedestal with an unintended advantage. "That is the implication, though we cannot say that it made the difference in any one specific case," Barton said. Meanwhile, Setchell noted tongue in cheek that a red advantage may not be limited to sports. "Going by the recent election results, red is indeed quite successful," she said.

单选题Trying to Find a Partner One of the most striking findings of a recent poll in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to start a family with. Why are many finding it increasingly difficult to start and sustain intimate relationships? Does modern life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for economic security or status. A man doesn't expect his spouse to be in sole charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence. In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soulmate (心上人) was constrained (限制) by geography, social convention and family tradition. Although it was never explicit, many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster (牡蛎), you surely have a better chance of finding a pearl. But it seems that the old conventions have been replaced by an even tighter constraint: the tyranny of choice. The expectations of partners are inflated (提高) to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression. We think that a relationship can be perfect. If it isn't, it is disposable. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Of course, this is complicated by realities. The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership.

单选题{{B}}第三篇{{/B}} {{B}}Knitting{{/B}} My mother knew how to knit, but she never taught me. She assumed, as did many women of her generation, that knitting was no longer a skill worth passing down from mother to daughter. A combination of feminism, consumerism and household gadgetry made many women feel that such homely accomplishments were now obsolete. My grandmother still knitted, though, and every Christmas she made a pair of socks for my mother and me~ of red wool. They were the ones we wore under our ice skates, when it was really important to have warm feet. Knitting is a nervous habit that happens to be productive. It helped me quit smoking by giving my hands something else to do. It is wonderful for depression because no matter what else happens, you are creating something beautiful. Time spent in front of the television or just siting is no longer time wasted. I love breathing life into the patterns. It's true magic, finding a neglected, dog-eared old book with the perfect snowflake design, buying the same Germantown knitting worsted my grandmother used, in the exact blue to match my daughter's eyes, taking it on the brain with me every day for two months, working feverishly to get it done by Christmas, staying up late after the stockings are filled to sew in the sleeves and weave in the ends. Knitting has taught me patience. I know that if I just keep going, even if it takes months, there Will be a reward and take out the stitches between and start over again. People often ask if I would do it for money, and the answer is always a definite no. In the first place, you could not pay me enough for the hours I put into a sweater. But more important this is an activity 1 keep separate from such considerations. I knit to recover my children and other people I live in warmth and color. I knit to give them earthly that money could never buy. Knitting gives my life an alternative rhythm to the daily deadline. By day I can write about Northern Ireland or the New York City Police Department and get paid for it, but on the time train home, surrounded by people with laptops, I stage my little rebellion. I take out my old knitting bag and join the centuries of women who have knitted for love.

单选题Outside-the-classroom Learning Makes a Big Difference Putting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky. When you consider the fact that the money is supposed to be given to children in need of medical care, you might call the idea crazy. Most student leaders don"t want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon"s operations officer for two years. Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining. At large universities like Fangmeyer"s, which has more than 40,000 students, the students first of all want to find a way to "belong in their own corner of campus". Katie Rowley, a Wisconsin senior, confirms the survey"s findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends." All of this talk of friendship, however, does not mean that students aren"t thinking about their resumes. "I think that a lot of people do join to "fatten up their resume"," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles." But without passion student leaders can have a difficult time trying to weather the storms that come. For example, in April, several student organizations at Wisconsin teamed up for an event designed to educate students about homelessness and poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, and dealing with the university"s complicated bureaucracy. "Outside—of the classroom learning really makes a big difference," Fangmeyer said.
