    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 too much. Too 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 .

    56. The author of this passage is primarily concerned with            .

     A. the signs and treatment for dehydration

     B. the long distance runners who need help

     C. how to manage water intake during a marathon

     D. a 28-year-old woman who died after a Boston Marathon

    57. Why do runners have to weigh themselves before and after a run ?

     A. They can improve their performance in a run.

     B. They can learn how much salt there is in the blood.

     C. They can know the quantity of water they’ve lost during a run.

     D. They can decide what kind of water they should take during a run.

    58. What conclusion can we draw from the passage ?

     A. Taking much salt during a run can avoid selling in the body.

     B. Either too much or too little of water intake is harmful.

     C. A rich meal is helpful to our performance in a run.

     D. We should take enough salt during a run.

    59．According the passage, which of the following statements is correct ?

     A. Too much water intake→blood sodium levels ↓→dehydration.

     B. Too much water intake→blood salt levels ↓→hyponatremia .

     C. No water intake→blood sodium levels↑→hyponatremia .

     D. No water intake →blood salt levels ↓→hyponatrenmia .

    Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

             So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?

             Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”

             What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

    1. What surprised the scientists a few years ago?

    A. Fatigue toxins could hardly be found in a laborer’s blood.

    B. Albert Einstein didn’t feel worn after a day’s work.

    C. The brain could work for many hours without fatigue.

    D. A mental worker’s blood was filled with fatigue toxins.

    2.According to the author, which of the following can make sitting workers tired?

    A. Challenging mental work.                           B. Unpleasant emotions.

    C. Endless tasks.                                                D. Physical labor.

    3.What’s the author’s attitude towards the scientists’ idea?

    A. He agrees with them.                                  B. He doubts them.

    C. He argues against them.                             D. He hesitates to accept them.

    4. We can infer from the passage that in order to stay energetic, sitting workers need to ___________.

    A. have some good food.                           B. enjoy their work

    C. exercise regularly                                  D. discover fatigue toxins

    In Japan, “what’s your type?” is much more than small talk; it can be a more important question in everything from matchmaking to getting a job. By type, the Japanese mean blood type, and no amount of scientific debunking (揭穿) can kill a widely held belief that blood tells all.

    In the year that just ended, four of Japan’s top 10 best-sellers were about how blood type determines personality, according to Japan’s largest book distributor, Tohan Co. Taku Kabeya, chief editor at Bungeisha, thinks the appeal comes from having one’s self-image confirmed; readers discover the definition of their blood type and “It’s like ‘Yes, that’s me!’“

    As defined by the books, type As are sensitive perfectionists but overanxious; type Bs am cheerful but weird and selfish; Os are curious, generous but stubborn; and Abs are arty but mysterious and unpredictable. All that may sound like a horoscope(占星), but the public doesn’t seem to care. Nowadays matchmaking agencies provide blood-type compatibility (兼容性) tests, and some companies make decisions about assignments based on employees’ blood types. Children at some kindergartens are divided up by blood type, and the women’s softball team that won gold at the Beijing Olympics used the theory to customize each player’s training.

    Blood types, determined by the proteins in the blood, have nothing to do with personality, said Satoru Kikuchi, associate professor of psychology at Shinshu University. “It’s simply false science, “he said, “The idea encourages people to judge others by the blood types, without trying to understand them as human beings. It’s like racism.” This use of blood-typing has disreputable (名声不好的) roots. The theory was imported from Nazi race ideologues (空谈家) and adopted by Japan’s militarist government in the 1930s to breed better soldiers. The idea was abandoned years later and the craze faded. It resurfaced in the 1970s, however, as Masahiko Nomi, a supporter with no medical background, gave the theory mass appeal. His son, Toshitaka now promotes it through a private group, the Human Science ABO Center, saying it’s not intended to rank or judge people but to smooth relationships and help make the best of one’s talents.

    1. That many Japan’s best-sellers were about blood type implies ____________.

    A. this topic is used by many people in small talks

    B. Japanese attach great importance to blood type

    C. people don’t want to have confirmed self-image

    D. the definition of blood type leads to arguments

    2. According to the passage, ________ may face more pressure while performing a task.

    A. type As   B. type Bs    C. type Os    D. type ABs

    3. Kikuchi compared blood type determinism to racism because ______________.

    A. both blood type and race are determined by the proteins in the blood

    B. neither blood type nor race is related to our character and personality

    C. both of them judge people without considering their individualities

    D. blood type determinism believes human abilities are decided by race

    4. Who introduced the blood type theory to Japan?

    A. Nazis from Germany.                                  B. Japan’s militarist government.

    C. A supporter called Masahiko Nomi.         D. Human Science ABO Center.
