Tears came into this mother's eyes when she talked about waking up her son. Every morning, her ten-year-old boy puts up one finger with his eyes still closed, begging for one more minute to sleep. Why is he so sleepy? Because, like thousands of student "early birds" in China, he has to get up before 6 a.m. every morning. School students usually need eight to ten hours' sleep a night. But in Shanghai, it's reported that 90% of the students do not get enough sleep. And studies show that without a good night's sleep, students seem to be weaker than they should be. Many become near-sighted as a result. Li Ming, a student at Qinghua High School, said that he usually goes to bed after 11 p.m. But when he has exams coming up, he can stay up as late as midnight. This "night bird" lifestyle has made many students nod off in class. Li Ming said that it is during afternoon classes that he feel most sleepy. "My parents are usually happy to see me studying so late," he said. "They think I work very hard and they make me cups of coffee." However, not all parents are happy about this. "My daughter gets up so early. She looks tired and it really hurts me." said one of the parents. Why don't so many students get enough sleep? Now many members of society began to think about it. Why did the ten-year-old boy's mother talk about waking up her son with tears in her eyes? A) Because her son's lack of sleep hurt her but she had to wake him up. B) Because her son wasn't good at lessons. C) Because she thought her son was too lazy. D) Because her son was badly ill.

(Question)
Anyone can try to lead a group, but not every individual is cut out for leadership. The better leaders possess a few qualities that can mean the difference between the success and failure of the group. These aret he qualities the leader of higher rank will look for when choosing a leader for a group, or when evaluating the performance of a leader. They're also the qualities team members want in a group leader, and appreciate when they find them. Take Responsibility Group leaders might share tasks around a group as necessary, but eventually a group leader needs to be able to accept that responsibility lies on her shoulders. That means that if things go wrong in a group project, she's the one who must accept the consequences and work out what mistakes were made. The group leader won't always have the power to control everything group members do, but she should be ready to admit any mistakes the group has made as a result of her leadership. Concern for Members The group leader has a commitment to the task or project at hand, but perhaps more importantly, he has a real concern for each and every person who is part of his group. This means getting to know the strengths, weaknesses and goals of team members, as well as making time to build the group through collective activities. The group leader should make sure that everyone is included, even if an individual is new to a group. Good Listener The group leader needs to be able to listen to the suggestions, complaints and ideas of group members. Not only will this allow complaints to be addressed and potentially suitable ideas to be put into practice, but a leader who listens will also encourage group members to share their concerns and thoughts,creating an atmosphere of free speech and productivity. A good leader should always be able to _ . A) tell when things go wrong in a group project. B) control everything group members do. C) make group members admit their mistakes. D) recognize any mistakes as his own.

Ques: Over the years, Americans have become used to salt.Most people have no idea how much salt they consume-on average, about 9 to 12 gram per person per day, according to the American Heart Association.That's twice the amount recommended by the government. A new study last week showed eating even a little less salt could greatly help the heart.The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease. Researchers also found that the benefits would be greatest for African Americans and women.As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr.Kirsten Bibbins-Domingo, an epidemiologist at the University of California, San Francisco.Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%.A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%. They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. However, other scientists say such a campaign is an experiment with the health of millions of people. Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure.But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. "Salt has other biological effects. Calling for reductions in the national diet could have good effects, as well as harmful results. There is not enough evidence either way,"said Michael Alderman. What can we learn from the passage? A) Most Americans take more salt than advised. B) African women eat more salt than Americans. C) One's origin determines how much salt he can eat. D) Good health is just on the basis of having less salt.
