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.
