While this undoubtedly helps shortterm memory.” 譯為“許多人認(rèn)為反復(fù)是記憶的最好方式。 DAll in the memory… Many people plain that their memory is bad, especially as they get older. Phone numbers, names, facts we studied only a few days ago — life would be so much easier if we could remember them all effortlessly. So how can we improve our memory? Many people think that repeating things is the best way to remember them. While this undoubtedly helps shortterm memory (remembering a telephone number for a few seconds, for example), psychologists (心理學(xué)家) doubt whether it can help you to remember things for very long. The British psychologist E. C. Stanford seemed to prove this point when he tested himself on five prayers (祈禱文) that he had read aloud every morning for 25 years. He found that he could remember no more than three words of some of them! More helpful, especially for remembering numbers, is grouping the information. The following numbers would be impossible for most of us to remember: 1492178919931848. But look at them in chunks, and it bees much easier: 1492 1789 1993 1848. So what about “memory training”? We’ve all heard about people who can memorize packs of cards by heart — how is this done and can anyone learn how to do it? According to experts, there are many ways of training your memory. Many of them involve forming a mental picture of the things to be memorized. One method, which may be useful in learning foreign languages, is to create a picture in your mind connected to a word you want to remember. Another method is to invent a story that includes all the things you want to remember. In experiments, people were asked to remember up to 120 words using this skill。選項(xiàng)D譯為“我們需要睡多少時(shí)間”，針對(duì)這個(gè)觀點(diǎn)在第一段結(jié)尾處提出問題，只是在第二段進(jìn)行解答，后面沒有圍繞該觀點(diǎn)展開講解，選項(xiàng)D為以偏概全，故D選項(xiàng)排除。選項(xiàng)B譯為“我們?nèi)绾文軌蛩酶谩保诘箶?shù)第二段中講到的是如何能夠讓清醒的狀態(tài)（不睡眠）保持更持久，故排除選項(xiàng)B。所以縱觀全文作者是在突出睡眠時(shí)間選擇。29. What is probably the best title of the passage?A. To Sleep or Not to Sleep?B. How can We Sleep Longer?C. To Work or Not to Work?D. How Much can We Sleep?【正確答案】A 【解題思路】本題考查主旨題。選項(xiàng)C文中沒有提及，屬于無(wú)中生有，故選項(xiàng)C排除。通過文中第三段第三句：“believes people’s sleep needs are different.”無(wú)法判斷人們的睡眠是否充足，因?yàn)槊總€(gè)人的需求不同，選項(xiàng)A太過絕對(duì)，故排除A。故正確答案為選項(xiàng)C。 C In the days before electricity, people don’t worry much about sleep. They usually went to bed a couple of hours after sunset（日落）and woke at sunrise. After all, there wasn’t much to do in those days after the sun went down. But then came the electric light bulb（電燈泡）. And now we have satellite television, the Internet, 24hour convenience stores, and longer hours at work. How much can we sleep? How much should we sleep? Like it or not ,many of us are sleeping less on average（平均）. In 1910, most Americans slept 9 hours a night. That dropped to hours by 1975. In 2002, a study by the National Sleep Foundation found that the average American got only hours. The news is even worse for people who work the night shift. They sleep an average of just 5 hours. Are we sleeping enough? Not if you believe in the old rule of eight hours of rest, eight hours of work, and eight hours of play. On the other hand, Norman Stanly, a British scientist who studies sleep, believes people’s sleep needs are different. Some people need as many as 11 hours, but others need as few as three. How much do you really need? “To find out,” he says, “simply sleep until you wake naturally, without the help of an alarm clock. That’s your sleep need.” Meanwhile, other scientists and researchers are searching for new ways to keep us awake longer. Some are developing chemicals（化學(xué)藥品）that are safer and more powerful than caffeine , the chemical found in coffee and tea. One experimental drug, CX717, kept laboratory monkeys working happily for 36 hours. Further developments may allow people to safely stay awake for several days straight. One group of researchers is studying a gene（基因）found in some fruit flies that lets them get by on onethird the usual amount of sleep. Another group is even working on an electric switch that immediately wakes up a sleeping brain. The meanings of this research are huge. On the one hand, this could lead to a world where we work longer and longer hours with less and less sleep. On the other hand, if we needed less sleep, we
