Birds are literally half-asleep--with one brain hemisphere alert and the other sleeping, according to a new study of sleeping ducks.
Earlier Studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird flocks led researchers to predict extra alertness in the more vulnerable, end-of-the-row sleepers. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.
Also, birds dozing (打盹) at the end of the line resorted to single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 16 birds through the positions in a four-duck row, the researchers found outer birds half-asleep during 32 percent of dozing time versus about 12 percent for birds in internal spots.
"We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness simultaneously in different regions of the brain," the researchers say.
The results provide the best evidence for a long-standing supposition that single- hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the. lockout side could be widespread, he predicts. He's seen it in a pair of birds' dozing side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half-sleeping might be, it's only been found in birds and such water mammals (哺乳动物) as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds' half-brain sleep "is just the tip of the iceberg (冰山) ". He speculates that more examples may turn up when we take a closer look at other species.
A new study on birds' sleep has revealed that ______
A．half-brain sleep is found in all kinds of birds
B．half-brain sleep is characterized by accelerated brain waves

It doesn't matter when or how long a person sleeps, but everyone needs some rest to stay alive. That's what all doctors' thought, until they heard about Jercy Page. Jercy Page, it was said, never slept. Could this be true.'？ The doctors decided to see this strange man by themselves.
Jercy Page was ninety years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Jercy Page sleeping. Actually, he did not even own a bed. He never needed one.
The only rest that Jercy Page got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition. Page remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason？ No one could be sure.
The main idea of this passage is that ______.
A．large numbers of people do not need sleep
B．a person was found who actually didn't need any sleep
C．everyone needs some sleep to stay alive
D．people can live longer by trying not to sleep

There must be few questions on which responsible opinion is so utterly divided as on that of how much sleep we ought to have. There are some who think we can leave the body to regulate these matters for itself. "The answer is easy," says Dr. A. Burton. "With the tight amount of sleep you should wake up fresh and alert five minutes before the alarm tings." If he is right many people must be under sleeping, including myself. But we must remember that some people have a greater inertia than others. This is not meant rudely. They switch on Slowly, and they are reluctant to switch off. They are alert at bedtime and sleepy when it is time to get up, and this may have nothing to do with how fatigued their bodies are, or how much sleep they must take to lose their fatigue.
Other people feel sure that the present trend is towards too little sleep. To quote one medical opinion, "Thousands of people drift through life suffering from the effects of too little sleep; the reason is not that they can't sleep. Like advancing colonists, we do seem to be grasping ever more of the land of sleep for our waking needs, pushing the boundary back and reaching, apparently, for a point in our evolution where we will sleep no more. This in itself, of course, need not be a bad thing. What could be disastrous, however, is that we should press too quickly towards this goal, sacrificing sleep only to gain more time in which to jeopardize our civilization by actions and decisions made weak by fatigue.
Then, to complete the picture, there are those who believe that most people are persuaded to sleep too much. Dr. H. Roberts, writing in Every Man in Health, asserts it may safely be stated also. It would be a pity to retard our development by holding back those people who are gifted enough to work and play well with less than the average amount of sleep, if indeed it does them no harm. If one of the trends of evolution is that more of the life span is to be spent in gainful waking activity, then surely these people are in the van of this advance.

B．among many issues the right amount of sleep is the least controversial
C．people are now moving towards solving many controversial issues
D．the right amount of sleep is a topic of much controversy among doctors
