单选题Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labour through your work you may say that you' re "hot". That' s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as, "Get up, John] Yon' 11 be late for work again!" The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can' t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won' t change your cycle, but you' 11 get upstream and work better at your low point. Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

单选题Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the country’s resources which can be combined with other resources to produce the goods and services required by the community. 　　Though the size of the workforce relies greatly on the size of the total population, there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural increase, i. e. the number of births greatly exceeds the number of deaths, then as a total population increases the proportion in the workforce declines. 　　Sometimes a population is described as aging, which means that the birth rate is either falling or growing very slowly ,and as people retire from the workforce there are unadequate numbers of young people entering it to take place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid in- crease in births or a falling birth rate. 　　The age distribution of the population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the work force, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes or hotels, finance must be available for that purpose. If the size of the workforce is small relative to the total population, then the government tax receipts are relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.

单选题 The principal technique in current use for teaching reading at the intermediate stage, a stage occurring between a beginning stage and an advanced stage, is that of graded readers. It is generally accepted that the achievement of fluency and that of a wider coverage of the language are desirable aims, and most teachers strive to obtain a large quantity of reading matter, often distinguishing between intensive and extensive reading. Two sources of difficulty exist: first, it is extremely difficult, in practice, for the teacher to meet the needs of each individual learner at the various different times that individuals actually become intermediate learners. Classwork presupposes that all learners progress from one stage to another at the same moment, which is not true. To try and get over this problem there is currently a wave of interest in individualization, that is, in providing within a common framework the opportunity for each individual learner to learn at least partly at his own rate; In reading, this is promoted by the provision of numbers of separate materials lots of small books ,or leaflets, or cards -- which become longer and more complex. (Reading kits are a case in point. ) This trend is certain to increase. The second difficulty is that the grading of reading materials has often proved inadequate ,in two senses: (a) by being self-defeating, so that "simplified" texts have frequently been "simplified" out of all sensible meaning; and (b) by the fact that many learners find vocabulary graded materials unappetizing: not that they can't learn from them, but that they won't. What is now being realized is that the grading of reading materials, and above all the choice of texts, must reflect not only characteristics of the language (vocabulary, grammar, etc. ) but also characteristics of the learner. What he is willing to read and what he is interested to read are products of his sex, age-group, level of education, degree of intellectuality, personal interests, etc. Reading materials are increasingly being designed to fit both the learner's level of proficiency in English and his reading interests. In doing so, they are providing the learner with the means of developing further command of the linguistic meanings of writing, enabling him to grasp informational and logical meaning, and perhaps starting him on the understanding of rhetorical and implicational meanings.

单选题If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are ageing unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties. Contraction of front and side parts—as cells die of—was observed in some subjects in their thirties, but it was still not evident in some sixty-and seventy- year-olds. Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa"s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain ceils need. "The best way to maintain good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don"t rely on pocket calculators. "
