单选题Mr. Black was young and able. The boss liked him. Last month he was sent to China on business. Before he went back from China, he decided to boy something for Tony, the son of his boss. At first he didn't know what to buy for the boy. Suddenly he remembered that the buy liked birds very much, so he went to the bird market. He was glad to find that there were so many kinds of birds there. He bought four beautiful birds, then he told the boy about it on the telephone. As soon as Mr. Black returned to London by air, he went to Tony with the four birds. But on his way to the boss's home, one of them flew out of the cage (笼子) and there were only three birds left in it. Then Mr. Black bought a local (当地的) bird to take the place of the missing Chinese one. Tony of course was very happy when he saw the birds. But soon he found one of them was different from the other three. He asked, "It's a local bird, isn't it, Mr. Black?" "Yes, it is." Mr. Black answered, "It's an interpreter ( 译员 )./

单选题{{B}}Text 2{{/B}} Sleep is a funny thing. We're taught that we should get seven or eight hours a night, but a lot of us get by just fine on less, and some of us actually sleep too much. A study out of the University of Buffalo reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke--probably as a result of an underlying disorder that keeps them from sleeping soundly. Doctors have their own special sleep problems. Residents are famously short of sleep. It is not unusual for them to work 40 hours in a row without rest. They are not in the least worried about it, confident they can still deliver the highest quality of medical care. But an article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person s motor performance is comparable to that of someone who is drunk. Curiously, surgeons who believe that operating under the influence of alcohol is grounds for sacking often don't think twice about operating without enough sleep. "I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, Which runs a website for residents. Some are terrifying. "I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly planted my face into the wound." "Practically every surgical resident I know has fallen asleep at the wheel driving home from work." writes another. "I know of three who have hit parked cars. Another hit a ' Jersey gate' on the New Jersey Expressway, going 105km/h." "Your own patients have become the enemy," writes a third, because they are "the one thing that stands between you and a few hours of sleep." The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worded about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more rested staffers are available.

单选题However important we may regard school life to be, the fact cannot be denied that children spend more time at home than in the classrooms. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of school personnel or they can consciously or unconsciously hinder and thwart curricula objectives. Administrators have been aware of the need to keep parents apprised of the newer methods used in Schools. Many principals have conducted workshops explaining such matters as reading readiness programs, manuscript writing, and developmental mathematics. Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The many interviews carried on during the year as well as new ways of reporting pupils' progress, can significantly aid in achieving a harmonious interplay between school and home. To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural parental interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip, and engaging in scores of other activities that have a mathematical basis. If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics and, at the same time, enjoying the work. Too often, however, teachers' conferences with parents are devoted to petty accounts of children's misdemeanors, complaints about laziness and poor work habits, and suggestions for penalties and rewards at home. What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents' minds for the best utilization of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters' capacities.
