When your parents advise you to get an education in order to raise your income, they tell you only half the truth. What they really mean is to get just enough education to provide manpower for your society, but not so much that you prove an embarrassment to your society. Get a high school diploma, at least. Without that, you will be occupationally dead unless your name happens to be George Bernard Shaw or Thomas Alva Edison, and you can successfully dropout in grade school. Get a college degree, if possible. With a B.A., you are on the launching pad. But now you have to start to put on the brakes. If you go for a master's degree, make sure it is an M.B.A., and is famous law of diminishing returns begins to take effect. Do you know, for instance, that long-haul truck drivers earn more per year than full professors? Yes, the average 1977 salary for those truckers was $24000, while the full professors managed to earn just $23030. A Ph.D. is the highest degree you can get. Except for a few specialized fields such as physics or chemistry where the degree can quickly be turned to industrial or commercial purposes, if you pursue such a degree in any other field, you will face a dim future, there are more Ph.D.s unemployed or underemployed in this country than any other part of the world. If you become a doctor of philosophy in English or history or anthropology or political science or languages or-worst of all-in philosophy, you run the risk of becoming overeducated for our national demands. Not for our needs, mind you, but for our demands.Thousands of Ph.D.s are selling shoes, driving cars, waiting on table, and endlessly filling out applications month after month. They may also take a job in some high school or backwater college that pays much less than the janitor earns. You can equate the level of income with the level of education only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.

Many people believe that the glare (眩目的光) from snow causes snow blindness. Yet, dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snow blindness, when exposed to several hours of snow sight.The United States Army has now determined that glare from snow does not cause snow blindness in troops in a snow-covered country. Rather, a mans eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain (地带，地域). 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 muscles ache. Nature balances this irritation by producing more and more fluid which covers the eyeballs. The fluid covers the eyeball in increasing quantity until vision is obscured, and the result is total, even though temporary, snow blindness.Experiments led to 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 scouring (急速搜寻) the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.

What are the specific traits that will assist executives to climb the ladder of success? Opinions vary widely. Given approximately equal qualifications and circumstances, some claim the success factor is largely a matter of luck being in the right place at the right time. Others speak of an almost crazy devotion to work, combined with a degree of ruthlessness (无情，冷酷). One expert maintains that its undoubtedly a matter of how much education your mother had.To be successful, executives must possess four basic skills:First, drive. Business success takes an unusual amount of energy. A successful executive almost by definition is a striver. He will get tense when he is not striving.Second, people sense. Some say being able to judge people is more important than a high IQ. The skill can be instinctual (本能的), but in most cases it is painstakingly learned.Third, communications ability. Different executives make themselves understood in different ways. Some transmit ideas best face to face; others are masters of the telephone call; still others are persuasive writers. One way or another, they all communicate clearly.Fourth, calm under pressure. No businessman will get very far if he breaks down.

Park and monument officials in Washington, D.C., have recently expressed alarm at the increased vandalism to the city's stone and marble memorials. Visitors from all parts of the United States and the world seem to want to take parts of the monuments home with them.These souvenir collectors chip off pieces of stone when the guards are not looking.

Monument officials are concerned not only that various sites are being defaced(损伤外观), but also that many are in danger of being structurally damaged and weakened.There are not enough guards to protect against random vandalism of this sort. Officials feel that only through increased awareness of the real cost to 奥鹏华中师范大学平时在线作业the nation will tourists stop damaging our public monuments.
