     If you're training for a marathon , a proper plan for water intake (攝入) is important. Of course,
there's the risk of dehydration (脫水).But athletes now know they can also get into trouble by drinking
too much. Too much water intake can lower levels of sodium (鈉) 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 .
1.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
2. 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.
3.What conclusion can we draw from the passage ?
A. Taking much salt during a run can avoid swelling 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.
4. 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 .

If you are a 30-plus plain Jane, or if you are not a local fresh graduate, get ready for the embarrassment(尷尬) in the job market. And you are just one of the millions to face discrimination（歧視）.
About 85 percent of the 3,424 people covered by a survey in 10 big cities, including Beijing and Shanghai, said discrimination in work and employment（就業(yè)） did exist. Also, the survey results given on Friday showed that 58 percent thought the problem to be severe（嚴重）.
Appearance, height and gender are the most discriminative categories（范疇）, the Beijing Morning Post reported.
Some requirements could be funny. The newspaper said Beijing citizen Zhang Meng, who had more than 10 years’ driving experience, failed to get a job because his possible employers considered his name to be “unlucky”.
“Meng”, they said, literally(字面上)means “rush” in Chinese, which made him more accident prone（傾向）than others.
Employers discriminate against people from certain regions or areas, such as Central China’s Henan Province, because of the bad impression they have about them. Beijing citizens, too, have their share of bad luck because they are generally considered lazy.
Cai Dingjian, a professor from China University of Political Science and Law, who headed the survey, said such requirements, which are not connected with the job itself, violate（侵犯）people’s equal right to look for a career. “It violates basic human rights,” he said to the newspaper.
Cai said governments should pay attention to such discriminations because they exist not only in companies, but are also practiced by them. One example is that civil servants(公務(wù)員) are usually required to have a pleasant personality.
