问题      Sleep is a funny thing. We’re taught that we should get seven or eight hours a night, but a lot of us get by just fine on less, and some of us actually sleep too much. A study out of the University of Buffalo last month reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke — probably as a result of an underlying disorder that keeps them from snoozing (睡) soundly.
     Doctors have their own special sleep problems. Residents (住院医生) are famously sleep deprived. When I was training to become a neurosurgeon, it was not unusual to work 40 hours in a row without rest. Most of us took k in stride, confident we could still deliver the highest quality of medical care. Maybe we shouldn’t have been so sum of ourselves. An article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person’s motor performance is comparable to that of someone who is legally intoxicated. Curiously, surgeons who believe that operating under the influence is grounds for dismissal often don’t think twice about operating without enough deep.
     "I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, which runs a website where residents can post anonymous anecdotes. Some are terrifying. "I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly face planted into the wound."
     "Practically every surgical resident I know has fallen asleep at the wheel driving home from work," writes another. "I know of three who have hit parked cats. Another hit a ’Jersey barrier’ on the New Jersey Turnpike, going 65 m. p. h." "Your own patients have become the enemy," writes a third, bemuse they are "the one thing that stands between you and a few hours of sleep."
     Agrawal’s organization is supporting the Patient and Physician Safety and Protection Act of 2001, introduced last November by Representative John Conyers Jr. of Michigan. Its key provisions, modeled on New York State’s regulations, include an 80-hour workweek and a 24-hour work-shift limit. Most doctors, however, resist such interference. Dr. Charles Binkley, a senior surgery resident at the University of Michigan, agrees that something needs to be done but believes "doctors should be hound by their conscience, not by the government."
     The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you’re worried about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more-rested staffers are available. Doctors, for their part, have to give up their pose of infallibility (不出错) and get the rest they need.  
What can we learn from Paragraph 1?
选项 A、People who sleep less than 8 hours a day are more prone to illness.
B、Poor sleep quality may be a sign of physical disorder.
C、Stroke is often associated with sleep.
D、Too much sleep can be as harmful as lack of deep.
答案B
解析 本题为推理题，问“第一段暗含了什么意思”。第一段最后一句话提到“... people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke—probably as a result of an underlying disorder that keeps them from snoozing(睡)soundly.”，意思是那些每天习惯睡八个小时以上但仍然感觉疲劳的人死于中风的危险是普通人的三倍，这也许这是一种潜在的紊乱导致的结果，正是这种紊乱才让他们难以安睡。由此句可以看出潜在的紊乱可能导致人们睡眠质量不高，虽然睡眠时间长，但仍然感到疲惫。因此B项“睡眠质量不高可能是身体紊乱的征兆”为正确项。
