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 everyone has a daily energy cycle.During the hours when you labor 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 tem-perature is at its peak (顶峰). 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 (自言自语) as: "Get up, John. You'll be late for work again. " The possible explanation to the trouble is that John is at his temperature-an-ener-gy peak in the evening. (80) Much family quarrelling ends when husbands and wives real-ize 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. Dr. Kleitman believes that habit can help. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually stay-ing up later than you want. 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'll get up steam (振作精神) and work better at your low point.Get off to a slow start which saves your energy. Get up with a leisurely yawn (打哈欠) 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. When-ever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

单选题All over the world mention of the British education suggests a picture of the "public school", and it suggests in particular the names of certain very famous institutions—Eton, Oxford and Cambridge; but people do not always realize what place these situations occupy in the whole educational system. Oxford and Cambridge are universities each having about 12,000 students out of a total of over 250,000 students at all British universities. Eton is a public school, and the best known of the public schools, which, in spite of their names, are not really public at all, but independent and private secondary schools taking boys from the age of thirteen to eighteen. The public schools in reality form a very small part of the school system of secondary education of Great Britain; only about one out of forty English boys goes to a public school, and one out of 1500 to Eton. Apart from the so-called public schools there is a complete system of state primary and secondary education, which resembles in its general form the state education in most other countries. All children must, by law, receive full-time education between the ages of five and sixteen. Any child may attend, without paying fees, a school provided by the public authorities, and the great majority attend such schools. They may continue, still without paying fees, until they are eighteen. The public schools, although unimportant numerically , have been England"s most peculiar and characteristic to educational methods, and they have an immense influence on the whole of English educational practice and on the English social structure.
