问题     The typical picture of a corporate highflier is someone who survives on very little sleep. He or she rises when it is still dark, works late and is still answering emails at two o’ clock in the morning. Such people do exist, of course. The late British Prime Minister Margaret Thatcher, for example, was famous for operating on a few hours’ sleep. Some entrepreneurs and Wall Street traders seem to follow suit.
    But if you think you need to do the same thing to get ahead, think again. A growing body of research is finding that, on the contrary, those who get a good night’s sleep are usually more productive at work. That’s because sleep doesn’t just rest the brain, say medical specialists. It allows the brain to perform vital maintenance and restoration tasks. Brains that get too little sleep simply cannot perform as well as those that are rested. "There’s no doubt that sleep deprivation affects job performance," says the Detroit Medical Center’s Safwan Badr. "The evidence is compelling that when you do not get enough sleep ... you are not as productive."
    Investors should also take heed: Numerous studies have found that those running on too little sleep tend to make poorer investment decisions and take needless risks as well. Charles Czeisler, a sleep specialist at Brigham & Women’s Hospital in Boston, agrees. "Missing a night’s sleep degrades our neurobehavioral performance"—that is, our mental acuity—"by the equivalent to being legally drunk," he says. And, he warns, this doesn’t only apply if you miss one night’s sleep completely; you’ll see similar effects if you simply sleep too little each night over time.
    For the first time, new research has attempted to put some numbers on the link between more Zzzs and more Benjamins. Matthew Gibson, graduate researcher in the economics department of the University of California, San Diego, compared wage data with sleep times recorded in the U.S. Census Bureau’s American Time Use Survey. His conclusion: For those who are sleeping too little, "a onehour increase in longrun average sleep increases wages by 16%, equivalent to more than a year of schooling."
    Adults need eight hours of sleep on average, experts say. There is some variation between individuals. But when we are tired, we find it much harder to think innovatively and to make creative leaps, say researchers. We find it harder to adapt our thinking to new information or to learn new lessons. Consider: At England’s Loughborough University in 1999, researchers Yvonne Harrison tested the effects of sleep deprivation on a small group of healthy young participants. They were given complex business-situation tasks in the form of a game, as well as some critical reading tasks. Those who went short on sleep were able to keep up with the reading, they found. But when it came to the complex game, "their play collapsed," they Reported.
[A] agrees that sleep deprivation brings bad effects to investment.
[B] holds that adults need an average of 8 hours’ sleep.
[C] believes that lack of sleep diminishes your performance.
[D] thinks it is difficult for people lacking sleep to take up creative work.
[E] points out the relation between sleep time and American dollars.
[F] is well known for very little sleep.
[G] maintains that sleep can rest the brain, and let the brain do other important tasks.

选项

答案A

解析 根据题干关键词Charles Czeisler定位到第三段。通过Charles Czeisler说的话很难判断出他的观点,如“一晚上没睡会将我们的神经行为表现(即灵敏度)降低到法定醉酒的水平”“不仅是整晚没睡会出现这样的情况,如果长期以来一直睡眠过少也会产生类似的影响”。但是该段开始就指出它的主题——睡眠对投资(者)的影响,即“睡眠时间过少的人做的投资决定也更差,同时还会承担不必要的风险”,而Charles Czeisler也同意这种观点,故A项“同意睡眠不足会给投资带来的不好影响”为正确答案。
