单选题Throughout the history of the arts, the nature of creativity has remained constant to artists. No matter what objects they select, artists are to bring forth new forces and forms that cause change—to find poetry where no one has ever seen or experienced it before. Landscape (风景) is another unchanging element of art. It can be found from ancient times through the 17th-century Dutch painters to the 19th-century romanticists and impressionists. In the 1970s Alfred Leslie, one of the new American realists, continued this practice. Leslie sought out the same place where Thomas Cole, a romanticist, had produced paintings of the same scene a century and a half before. Unlike Cole who insists on a feeling of loneliness and the idea of finding peace in nature, Ledge paints what he actually sees. In his paintings, there is no particular change in motion, and he includes ordinary things like the highway in the background. He also takes advantage of the latest developments of color photography (摄影术) to help both the eye and the memory when he improves his painting back in his workroom. Besides, all art begs the age-old question: What is real? Each generation of artists has shown their understanding of reality in one form or another. The impressionists saw reality in brief emotional effects, the realists in everyday subjects and in forest scenes, and the Cro-Magnon cave people in their naturalistic drawings of the animals in the ancient forests. To sum up, understanding reality is a necessary struggle for artists of all periods. Over thousands of years the function of the arts has remained relatively constant. Past or present, Eastern or Western, the arts are a basic part of our immediate experience. Many and different are the faces of art, and together they express the basic need and hope of human beings.

单选题Do you ever feel sick, confused, or very tired after a long plane ride? If you were fly-ing east to west or west to east, the problem could have been jet lag. (45) Jet lag happens when your body's time clock becomes confused. Crossing several time zones may make you feel very tired. You may become confused because you are tired. In fact, you may become so confused that you won't be able to do your work. You might get headaches and feel that you have problems eating and sleeping. These are all symptoms of jet lag. However, if you feel tired after flying from north to south or south to north, you do not have jet lag. Maybe you feel tired from the tiredness and work of getting ready for the trip. You will feel better after you get some sleep. The symptoms that you feel during a flight, such as thirst and motion sickness, are not jet lag either. They are caused by the air pressure in the plane. When you travel north or south, you do not cross time zones. So you do not have true jet lag.

单选题Industrial psychology is the application of various psychological techniques to the selection and training of industrial workers and to the promotion of efficient working conditions and techniques, as well as individual job satisfaction. The selection of workers for particular jobs is essentially a problem of discovering the special aptitudes and techniques, and personality characteristics needed for the job and of devising tests to determine whether candidates have such aptitudes and characteristics. The development of tests of this kind has long been a field of psychological research. Once the worker is on the job and has been trained, the fundamental aim of the industrial psychologist is to find ways in which a particular job can best be accomplished with a minimum of effort and a maximum of individual satisfaction. The psychologist's function, therefore, differs from that of the so-called efficiency expert, who places primary emphasis on increased production. Psychological techniques used to lessen the effort involved in a given job include a detailed study of the motion required to do the .job, the equipment used, and the conditions under which the job is performed. After making such a study, the industrial psychologist often determines that the job in question may be accomplished with less effort by changing the routine motions of the work itself, changing or moving the tools, improving the working Conditions, or a combination of several of these methods. Industrial psychologists have also studied the effects of fatigue on workers to determine the length of working time that yields the greatest productivity. In some cases such studies have proven that total production on particular jobs could be increased by reducing the number of working hours or by increasing the number of rest periods, or "breaks", during the day. Industrial psychologists may also suggest less direct requirements for general improvement of job performance, such as establishing a better line of communication between employees and management.

单选题After 20 years of marriage, a husband may still not understand his wife. How is it that she is never at a 1 for words? How can she recall the names of a couple they met on holiday years ago? Now we know 2 to tell him: it"s her brain. Although there are obviously cultural reasons for the differences in emotions and behavior, recent breakthrough research reveals that the root of many puzzling differences between men and women may 3 in the head, Men"s and women"s brains 4 much in common, but they are definitely not the same 5 size, structure or insight. Broadly speaking, a woman"s brain, like her body, is ten to fifteen percent smaller than a man"s, 6 the regions dedicated to language may be more densely packed with brain cells. Girls generally speak earlier and read faster. The reason may be 7 females use both sides of the brain when they read. In 8 , males rely only on the left side. At every age, women"s memories top men"s. They have a greater ability to associate names with faces than men do, and they are 9 at recalling list. The events people remember best are those that an emotion is attached to. Since women use more of their right brains, which process emotions, they may do this automatically. While we don"t yet know what all these findings imply, one thing is 10 : male and female brains do the same things, but they do them differently.
