If you’re training for a marathon, a proper plan for water intake （摄入） is important. Of course, there’s the risk of dehydration （脱水）. But athletes now know they can also get into trouble by drinking to much . To much water intake can lower levels of sodium （钠） in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.

Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.

One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.

Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water.

B 

　Two experts did some experiments on two groups of people — one who tended to sleep less than the

people around them and the other group more.

According to their report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men automatically began to cut down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.

　　 In general, these “short sleepers” appeared with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them had a strong urge to appear “acceptable” or “outstanding” to their friends and associates.

　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering them. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.

　　The experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.

　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.

All in all, proper time of sleeping should be admired, not too long, neither too short.

According to the report, ______.

　 A. many “short sleepers” need less sleep just by nature

　 B. many “short sleepers” are obliged to reduce sleep time by work

　 C. long sleepers sleep a longer period of time during the day

　 D. many “long sleepers” formed sleeping habit during childhood

Many “short sleepers” are likely to hold the view that ______.

　 A. sleep is a very efficient escape from the reality

　 B. sleep is just an item which should be denied by them

   C. sleep might be a disturbing thing for their daily business

　 D. sleep is the best way to deal with psychological troubles

It is stated in the forth paragraph that “short sleepers” ______.

　 A. are ideally energetic under the pressures of life

　 B. often ignore the ill effect of not enough sleep

　 C. do not know how to relax themselves properly

　 D. are more unlikely to run into mental problems

Which of the following is nearest to the meaning of “… were a bit concerned ” in the fifth Para?

　 A. appeared troubled                     B. became energetic

C. felt dissatisfied                       D. were much depressed

Which of the following is NOT correct according to the passage?

　 A. If one sleeps improperly, his performance suffers and his memory is weakened

　 B. The sleep patterns of short sleepers are the same as those shown by “long sleepers”

　 C. Long and short sleepers differ in their attitudes towards sleep

　 D. Short sleepers may have been better off if they have more rest
