单选题Happy hours are not necessarily happy, nor do they last for an hour, but they have become a part of the ritual of the office worker and businessman. On weekdays in pubs and bars throughout America, there is the late afternoon happy hour. The time may vary from place to place, but usually it is held from four to seven. After the workday is finished, office workers in large cities and small towns take a relaxing pause and do not go directly home. They head off instead for the nearest bar or pub to be with friends, co-workers and colleagues. Within minutes the pub is filled to capacity with businessmen and secretaries, office clerks and stock executives. They gather around the bar like birds around a fountain or forest animals around a watering hole and chat about the trifles of office life or matters more personal. This is their desert garden, the place to relieve the day"s stress at the office. At these happy hours, social binding occurs between people who share the same workplace or similar professions. They may chat about each other or talk about a planned project that has yet to meet a deadline. In this sense, these places become extensions of the workplace and constitute a good portion of one"s social life.

单选题Communication is the sending of information or news from one person to another. If human beings could not communicate with one another, each person would have to learn everything for himself. Although animals as well as men can communicate, so far as we know, they can express only the simple emotions like pain, joy, fear, hunger, anger and love. Some animals have a more advanced form of language using sounds, and others use a wide range of sounds and face movements, but we still have much to learn about these animal languages. Speech is the most important means of communication between people. But it is not the only one. Nor is it the oldest. We use facial expressions, gestures and hand movements to express our feelings and to send signals to other people. Animals use this "body language" a great deal. The sign language used by deaf people is an example of communication without speech, while blind people communicate largely through touch and hearing.

单选题 There are great careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in a great area at a glance, people who perhaps know too much about any one field. There is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgments. And these "generalists" are particularly needed for positions in administration, where it is their job to see that other people do the work, where they have to plan for other people, to organize other people's work, to begin it and judge it. The specialist understands one field; his concern is with technique and tools. He is a "trained" man; and his educational background is properly technical or professional. The generalist- and especially the administrator- deals with people; his concern is with leadership, with planning, and with direction giving. He is an "educated" man; and the humanities fire his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in a particular field. Any organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly. Your first job may turn out to be the right job for you--but this is a pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.

单选题Many people believe the glare from snow causes snow blindness. Yet, dark glasses or not they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of "snow light". The United States Army has now determined that the glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of a snow-covered area. So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscle aches. Nature balances this annoyance by producing more and more liquid which covers the eyeballs. The liquid covers the eyeballs in increasing quantity until vision blurs. And the result is total, even though temporary, snowblindness. Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark-colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching through the snow-blanketed landscape. By focusing their attention on one object at a time, the man can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white area is overcome.
