There was once a professor of medicine, who was very strict with the students. Whenever he took the chair on the exam committee, the students would be in fear, because he was seldom pleased with the answers they gave. A student would be lucky enough if he or she could receive a good mark from him. At the end of the term, the students of medicine would take their exam again. Now a student was a little nervous as he knew it would not be so easy to get through the exam at all. The professor began to ask. The student was required to describe a certain illness, his description of which turned out to be OK. Then the professor asked about the cure for illness, and the student, too, answered just as right. "Good," said the professor, "and how much will you give the patient?" "A full spoon," answered the student. "Now you may go out and wait for what you can get," said the professor. At the same time the committee discussed carefully the answers the student had given. Suddenly the student noticed that there was something wrong with his last answer. "A full spoon is too much," he thought to himself. Anxiously he opened the door of the room and cried, "Mr Professor, I've made a mistake! A full spoon is too much for the patient. He can take only five drops." "I'm sorry, sir," said the professor coldly, "But it is too late. Your patient has died." Which of the following is NOT true? A) The patient will be in danger if he's taken as much as a full spoon. B) The doctor will be in trouble if he's given the patient a full spoon. C) Since one spoon is less than five drops, the patient will be all right soon if he takes only one full spoon at a time. D) If the patient wants to remain safe, he should take no more than five drops at a time.

Q: Sitting for more than three hours a day can decrease a person's life expectancy by two years, even if her or she is physically active and gets rid of dangerous habit like smoking ,according to a study. Watching TV for more than two hours a day can worsen that problem, decreasing life expectancy by another 1.4 years. The analysis comes just two years after Australian researchers found that people who said they watched TV for more than four hours a day were 46% more likely to die of any cause than people who said they spent less than two hours a day watching TV. Those watching TV more than four hours a day were also 80% more likely to die of cardiovascular disease. "Long-sitting behavior is something we need to take note of beyond telling people to get 30 minutes of activity a day ," said Peter T. Katzmarzyk, one of the lead researchers. But while the evidence of illnesses is increasing, it remains difficult for many people to find time to get on their feet, especially if they do desk jobs. "Try to stand as much as you can," Dr Katzmarzyk said. "Typically when you are on the telephone you can stand and use the speakerphone. Instead of e-mailing someone in the office, just get up and so to talk to them." However , Dr Katzmarzyk added, standing shouldn't be alternative to exercising, but an alternative to sitting . "Several studies show that when you're sitting , your leg muscles are completely inactive," he said . "When you're sitting and completely inactive, this is when you run into trouble managing blood sugar." The researchers draw the conclusion of the effect of long-sitting behavior by _ . A) making comparisons B) listing figures C) giving examples D) classifying facts

Q: When it came to role models, Diana Ortiz said her mother, Marcia Dominguez, was the "hero". Ms. Dominguez came to the United States from Cuba in 1979. She went to college and got a job as a social worker --- all the while raising three children in America mostly on her own. "It was always school first," Diana said, "My mom had us in a straight line. If we got out of line, she corrected us. She was a perfect woman. She was beautiful, she had the education and she had everything --- but the illness took over. When I was 11, it frightened me to see how quickly my mother's health was ruined by cancer. A week before I turned 14, my mother died at age 50. I had tried to prepare myself, but on the first morning I woke up without my mother, the sense of loss was painful." Diana had not seen her father for five years, who refused to provide for her. Diana then entered the city's foster care system. She has spent about four years in foster homes. Despite Diana's hard teenage years, the values her mother had planted in her mind inspired her to go after higher education. Since August 2010, she has been a fulltime student majoring in law. A public organization offers her tuition but she has part-time jobs to help people like her and earn more life experience. Her goal is a job in the Federal Bureau of Investigation. For now, Diana works 20 hours a week as a cashier at Marshalls, earning $7.25 an hour. In November, she moved into her own public housing studio apartment on the Lower East Side. She pays $236 a month in rent. Although she is out of foster care, Diana has been speaking at workshops for foster youths. She emphasizes that nothing should get in the way of their success, not the trials of their lives or what they may have lost. "I tell the young who have the similar experience like me, 'Why are you going to let what happened to you affect you in the long run?' " Diana said. " 'Why are you going to sit there and feel sorry for yourself? You're wasting precious time.' It is a message my mother would approve of. My...
