单选题Too Polite for Words A Japanese colleague the other day was talking about a meeting with a man whom she abruptly described using the English word "jerk". I thought she was toning clown her Japanese for my benefit,so I asked her how to say "jerk" in Japanese. "There's no such word,"she answered helplessly. "We have to use "jerk'". Heaven knows it's not as if there are no jerks in Japan. But the Japanese language is just not made for sniping at people. At first,I thought maybe my Japanese teachers had been too polite to teach me the real lingo,so I watched to see what Japanese drivers would say to each other after a car accident. It turned out that they say.-"I'm sorry. "Gradually I came to realize that there is perhaps no language so ill suited to invective as Japanese. Linguistically,these guys are wimps. Take the vicious Japanese insult "kisama, "which is deeply offensive. It means : "your honorable self. "That's right. Instead of using all kinds of dirty words, the Japanese insult each other by frowning and growling:"Your honorable self. " Likewise,a nasty expression for a woman is "ama,"another term not to try with the nice woman at the sushi restaurant. But literally it means "nun". Sure, sarcasm may be intended, but still most women would probably prefer to be characterized as a nun than as a female dog. Since people are least inhibited when they are shaking their fists at each other,insults offer a window into a culture. I've been interested in such terms ever since I arrived in Cairo a dozen years ago to study Arabic and discovered that my name was a curse. "Nick" sounds very much like the imperative of an extremely vulgar verb for sex. I would introduce myself in Arabic,and my new acquaintance would flee in horror. There's no such danger in Japanese. There are explicit terms for sex and for body parts, crude as well as clinical, but they are descriptive rather than insulting. There is one exception. One of the meanest things one Japanese child can say to another is:"Omaeno kaachan debeso. "That means. "Your mom's belly button sticks out. "This has no deep Freudian meaning;it simply means that your mother is rude and ugly.

单选题 Walking to Exercise the Brain Do you think sitting and studying all the time will improve your grades? Think again. Getting some exercise may help, too. New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise. Previous research had shown that mice learn, remember, and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don't. Their brain cells also make more connections. Neuroscientists from the University at Urbana-Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked 1 mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing. Adults who were physically fit were faster at the arrow task, and their answers were just as ac curate as their less-fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions. In a second study, 15 elderly people who completed a 6-month aerobic-training course were faster at attention tasks compared with 14 seniors who just did stretching and toning exercises for the same amount of time. So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for your grandparents. The effects of exercising on the brains of younger people haven't been studied yet. Still, it can't hurt to take occasional study breaks and go for a walk or run around with your friends. You might even do better in school. Whatever you do, though, don't try to read and walk at the same time. You could end up hurting yourself!

单选题下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} Sleep{{/B}} We all know that the normal human daily cycle of activity is of some 7---8 hours' sleep alternating with some 16--17 hours' wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The case, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls insistently for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 am one week, 8 am to 4 pm the next, and 4 pm to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another4, so that much of his time is spent neither working nor sleeping very efficiently. One answer would seem to be longer periods on each shift, a month, or even three months. Recent research by Bonjer of the Netherlands, however, has shown that people on such systems will revert to their normal habits of sleep and wakefulness during the weekends and that this is quite enough to destroy any adaptation to night work built up during the week. The only real solution appears to be to hand over the night shift to a corps of permanent night workers whose nocturnal wakefulness may persist through all weekends and holidays. An interesting study of the domestic life and health of night-shift workers was carded out by Brown. She found a high incidence of disturbed sleep, digestive disorder and domestic disruption among those on alternating day and night shifts, but no abnormal occurrence of these symptoms among those on permanent night work.

单选题 Happiness Happiness is becoming a huge area in psychological research and even in government policy, with the UK government exploring a "happiness index". It's tough, though, to define exactly what happiness is, and what makes us happy. There are two broad ways of looking at happiness: short-term happiness (a great cookie, a boodle of wine) and long-term happiness (financial security, achieving your goals). Both types of happiness are valid, and important. The problem is, they're often in competition. Let's say you've got a goal of losing 50 pounds this year. You know you'd be happier and healthier if you weren't carrying that extra weight. To achieve long-term happiness, you need to go on a diet. In the short-term, though, it's not that easy. A chocolate cake, or a large glass of wine, might seem like just the thing to cheer you up at the end of a long day—or to celebrate with friends. It's the same with lots of other goals. If you've got a tendency to {{U}}prioritize{{/U}} long-term happiness at the expense of day-to-day pleasures, you should start looking for some small ways to bring a little joy back into your life. I'm not suggesting that you go our and get drunk every night, or that you stuff with cake. There are plenty of other ways to enjoy yourself. Don't pin all your hopes of happiness on some far-off future, though. There's no point working a 60-hour week and making yourself thoroughly miserable in the belief that things will be prefect as soon as you're making a six-figure salary.

单选题The Race into Space American millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space and looking back at earth is one of the most rewarding experiences a human being can have." This kind of experience isn"t cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when I didn"t have any money," he told reporters. On April 30, 2002, Mark Shuttleworth became the world"s second space tourist. Shuttleworth is a South African businessman. At the age of twenty-eight, he also paid $20 million for the eight-day trip. Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn"t exist yet. Many of the customers are persons who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it"s so expensive, only very rich people can go into space. They want space travel to be available to more people. That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga, for $2 million. However, space flight is still very dangerous. Bill Readdy is NASA"s deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this it may take time before space tourism really takes off. You might be able to go up, but will you come down?

单选题How to Read Books A number of recent books have reworked subjects, forms and writing techniques. Today's children read stories about divorce, death, drugs, air pollution, political extremism and violence. Relying on the magic of the illustrator, all kinds of books are being published. Before they know how to read, babies can play with books made of cloth or books made to take in the bath. Later on, they are given picture books that may be cubical(立方形的) or triangular, outsized or very small. They also like work-books which come with watercolours and paintbrushes, and comic books(漫画册) filled with details where they have to spot a figure hidden among thousands of others. Not that the traditional children's books are being neglected. There are still storybooks where the pages pop up(跳起) when they are opened, to make a forest or a castle. Among the latest ideas are interactive stories where readers choose the plot(情节) or ending they want, and books on CD, which are very popular in rich industrialized countries. The public has enthusiastically greeted the wealth of creativity displayed by publishers. "Previously, giving a child a book was often seen as improper," says Canadian author Marie-France Hebert. Her books, published by a French-language publisher, sell like not cakes in hundreds of thousands of copies. "There's real appetite for reading these days and I try to get across to children the passion for reading which is food for the mind and the passion for reading which is food for the mind and the heart, like a medicine or a vitamin. /
