单选题Any corporation can"t be set up because they don"t want to make profits.

单选题Sometimes, people simply do not realize they are being ill mannered. Take Ted, for example. He prides himself on speaking his mind, and has something to say on everything. But his frankness is often extremely embarrassing. He is incapable of saying, "I thought that last advertising campaign had a lot of good ideas in it, but perhaps next time we could give the copy more vitality (活力)." Instead, he would say, "That campaign was a disaster. A child of three could have done better!" The fact that he is often right does not help. Other employees dislike his manner even more, but he is too insensitive to notice. Another character among the list of ill-mannered employees is Sally, who seems to regard just being at work as a severe punishment. Everything is done unwillingly. Asking her to do a task beyond her basic job description is often not worth the trouble. It will be done, but only half-heartedly. Fergus is just the opposite. He shows an over-familiarity to his boss. When an important visitor is shown into the manager"s office, Fergus cannot take the hint and leave. Instead he will attempt to take part in the conversation, declaring, "You can talk in front of me. Henry and I don"t have many secrets, do we?" Over the years Fergus has fallen behind his former equal. But he seeks to maintain the same close relationship that he imagines existed in their younger days.

单选题Cycle-cross is a cross-country bicycle racing in open and usually quite rough country with riders often forced to dismount and carry their bicycles. The sport, originated early in the 20th century in France, but became prominent in the 1950s (the British Cycle-Cross Association was founded in 1954). Originally as a European sport, cycle-cross became popular throughout Western Europe and in the United States . World championships were initiated in 1925; by 1950 these were recognized by the Union Cyclist International (International Cyclists" Union). After 1967 amateur and professional classes were officially separated in competition. The 24-kilometre cycle-cross course, often involving laps, is usually completed in 60 minutes. A course typically includes obstacles such as ditches, mud, fallen trees, streams, flight of stairs, fences and gates; artificial hurdles are added to insufficiently challenging natural courses. Cycle-cross races are usually held from September to March, adding winter weather hazards to the challenge. There is a massed start with the field assembling not more than two abreast. Helpers are often stationed around the course with spare bicycles in case the original machine encounters mechanical difficulties or becomes too weighted down by mud picked up to the course.

单选题 (A) When you learn a foreign language you must learn more than just the words and the grammar. To communicate successfully in speech, you must also learn the non-verbal language, or "body language" of that culture. "Body language" is a term used to describe facial expressions, gestures, and other movements of the body that send messages. This means of communication is so important that we may actually say more with our movements than we do with words. Unconsciously, everyone understands the importance of body language. That's why we stand on tiptoe (脚尖) in a crowded room to see a speaker's face and hands, even though we may be able to hear him very clearly. For some messages, words are not enough. Speaking a foreign language is sometimes difficult because we may not understand the non-verbal signals of another culture, or they may mean something very different from what they mean in our culture. For example, nodding the head up and down is a gesture that may communicate a different message in different parts of the world. In North America it means "I agree. " In the Middle East nodding the head down means "I agree" and up means "I disagree. " In a conversation among Japanese it often simply means "I'm listening. " One Japanese student in the U.S. learned the difference the hard way. While speaking with a salesman the student nodded his head politely to show that he was paying attention. The next day the salesman brought a new washing machine to the student's apartment. Eye contact is also meaningful, but it, too, can mean different things in different countries. In some Spanish-speaking countries, children show respect to an older person by not looking directly into the person's eyes during a conversation. In other cultures, looking into a person's eyes is expected. For example, if you don't do it in the U.S., people may think you are afraid or angry. In the Middle East, direct eye contact during a conversation is more continuous than in many other parts of the world. People who are not used to this may feel uncomfortable.

单选题(A) When doctors need information about what dose of medicine to prescribe, they usually consult a fat blue book called the Physicians" Desk Reference, or PDR. But the doses recommended in the PDR may be too high for many people and may cause bad reactions, ranging from dizziness (头晕) and nausea(恶心)all the way to death, according to an article published last month in the journal Postgraduate Medicine. For many drugs, smaller doses would work just as well, with far less risk of bad reactions, said the author, Jay Cohen, an associate professor at the University of California. "Side effects drive a lot of people out of treatment that they need," Dr. Cohen said. "People often gave up trying to treat their illnesses when they found that the cure was worse than the disease. But if doctors were to individualize doses for each patient, more people might take their medicine. " Dr. Cohen said he became aware of the problem because he met many patients who suffered from side effects even though they had taken what were supposedly the correct doses of medicine. When Dr. Cohen consulted medical journals and textbooks, he discovered studies showing that many patients were helped by smaller than usual amounts of medicine. And many of his own patients did better with reduced doses. Dosing guidelines generally tend to be too high because they are based on studies conducted with limited numbers of patients by drug companies when they are seeking approval for new products, Dr. Cohen said. For those studies to run efficiently, doses need to be high enough to show as quickly as possible that the drug works. But later, after the drug is approved, far more people take it, sometimes along with other drugs, and individual differences begin to show up. That information does not always make it into the PDR, Dr. Cohen said. Dr. Cohen cautioned that patients should not try to change doses of prescription on their own. He said they needed to work with doctors to adjust the doses safely.

单选题Some people say that seals are the fairies of the sea and should not be killed. The seals are the cleverest creatures that have ever been found in the sea. "In the Kingdom of the Seals" is an English fairy story by Donald A. Mackenzie, which tells of a seal hunter who wounds a seal. The seal swims away with the hunter"s knife still in its back. That evening a stranger on a black horse calls at the home of the seal hunter and takes him to the edge of a cliff. Suddenly the seal hunter finds himself falling. He falls to the bottom of the sea. The stranger changes into a seal and leads him towards a huge underwater palace. Inside the palace he sees an old grey seal lying on a bed in terrible pain. Beside the bed is a knife, which the hunter recognizes as his own. He is ashamed of his cruelty and begs forgiveness of the old seal. Soon the wound is healed when the seal hunter lays his hand on it and wishes. The old seal regains his strength straight away. The seal hunter promises never to hunt seals again. Then he is led back to dry land. When he gets home he finds his pockets are filled with pearls. In reality, true seals are earless. There are 18 species of careless seals. Fur seals are not true seals. Fur seals feed mainly on a small type of shrimp. When diving for food seals have been known to reach depth of 300 meters, but throughout the breading season of several weeks, male seals do not eat or drink.
