You will hear the conversation ONLY ONCE.You now have 1 minute to read Questions 1 to 10./I（分数：10.00）(1).Psychologists say there are two different kinds of loneliness.（分数

28、：1.00）A.正确B.错误 解析：听力原文1-10 Most people feel lonely sometimes, but it usually lasts only between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Psychologists are studying this complex phenonme

29、non in an attempt to better understand long-term loneliness. These researchers have already indentified three different types of loneliness. The first kind of loneliness is temporary, This is the most common type. It usually disappears quickly and does not require any special attention. The second k

30、ind, situational loneliness, is a natural result of a particular situation, for example, a divorce, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. Si

31、tuational loneliness is easy to understand and to predict. The third kind of loneliness is the most severe. Unlike the second type, chronic loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close t

32、o others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition. Psychologists agree that one important factor in loneliness is a persons social contacts, i. e. , friends, family members, coworkers, etc. We depend on various people for

33、different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that the number of social contacts we have is not the only reason for loneliness. It is more i

34、mportant how many social contacts we think or expect we should have. In other words, though lonely people may have many social contacts, they sometimes feel they should have more. They question their own popularity. Most researchers agree that the loneliest people are between the ages of 18 and 25,

35、so a group of psychologists decided to study a group of college freshmen. They found that more than 50 percent of the freshmen were situationally lonely at the beginning of the semester as a result of their new circumstances but had adjusted after a few months. Thirteen percent were still lonely aft

36、er seven months due to shyness and fear. They felt very uncomfortable meeting new people, even though they understood that their fear was not rational The situationally lonely freshmen overcame their loneliness by making new friends, but the chronically lonely remained unhappy because they were afra

37、id to do so. Psychologists are trying to find ways to help habitually lonely people for two reasons. First of all, they are unhappy and unable to socialize. Secondly, researchers have found a connection between chronic loneliness and serious illnesses such as heart disease. While temporary and situa

38、tional loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition.(2).All kinds of loneliness last only a short time.（分数：1.00）A.正确B.错误 解析：(3).Temporary loneliness is very serious.（分数：1.00）A.正确B.错误 解析：(4).Divorce sometimes causes loneline

41、u now have 15 seconds read Questions 11 to 14./I（分数：4.00）(1).What role do most people in the manufacturing trades play?（分数：1.00）A.Designers.B.Supervisors.C.Assistants.D.Employees. 解析：听力原文11-14 Manufacturing includes all occupations that are involved in making products by hand or by machine. These pr

42、oducts range from simple plastic or wooden objects, such as clothespins or toothpicks, to highly complicated electronic computers. Manufactured goods also vary in size, from microscopic electronic parts to giant aircraft carriers and supertankers. About two-thirds of the workers in manufacturing act

43、ually make products. These employees include craft-workers, skilled and semiskilled workers, and unskilled laborers. Craft-workers are highly skilled in such trades as tool designing, tool and die making, and tailoring. Many craft-workers supervise other employees. Skilled workers, who include engra

44、vers, machinists, printers, and welders, use special job skills to make items or to operate machinery. Semiskilled workers include machine operators and assistants to skilled workers. Many semiskilled occupations require workers to repeat the same task again and again. Unskilled laborers perform job

45、s that require no special skills, such as sorting, packing, or moving materials. Most employees in manufacturing work in factories or shops. Common working conditions include high levels of dust, heat, or noise. Some factory jobs require great strength or standing for long periods. Many scientists,

46、engineers, and technicians also work in manufacturing. Scientists perform laboratory testes and other research to develop new products and improve old ones. Engineers design and test airplanes, automobiles, household appliances, machine parts, and countless other products. They also design production equipment and improved manufacturing techniques. Some technicians assist scientists and engineers. Others plan or su
