According to a survey, which was based on the responses of over 188,000 students, today’s traditional-age college freshmen are "more materialistic and less altruistic (利他主义的)" than at any time in the 17 years of the poll. Not surprisingly in these hard times, the students’ major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That’s no surprise, either. A friend of mine (a sales representative from a chemical company) was making twice the salary of her college instructors during her first year on the job even before she completed her two-year associate degree. While it’s true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions, be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More importantly, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who go on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is ta]king on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong" From the long-term point of view, that’s what education really ought to be about. The students’ criteria for selecting majors today have much to do with ______.
Flying the Hypert Skies A little airplane has given new meaning to the term "going hyper. " The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. That’s about 5,000 miles per hour. At this speed, you’d get around the world -- flying along the equator (赤道) -- in less than 5 hours. The Hyper-X is an unmanned,experimental aircraft just 12 feet long. It achieves hypersonic (超音速的) speed using a special sort of engine known as a scramjet. It may sound like something from a comic book,but engineers have been experimenting with scramjets since the 1960s. For an engine to burn fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet (紧急刹车) engine goes as fast as a rocket, but it doesn’t have to carry its own oxygen supply. A scramjet’s special design allows it to obtain oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion (燃烧) flames. However, a scramjet engine works properly only at speeds greater than five times the speed of sound. A booster rocket carried the Hyper-X to an altitude of about 100,000 feet for its test flight. The aircraft’s record-beating flight lasted just 11 seconds. Although the little plane’s self-powered flight lasted only 11 seconds, that brief journey on March 27 makes a major milestone on the way to a new breed of very fast airplanes, comments Werner J. A. Dahm of the University of Michigan in Ann Arbor. In the future, engineers predict, airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink of space. Such hypersonic jets could potentially carry passengers anywhere in the world in just a few hours. Out of the three experimental Hyper-X aircrafts built for NASA, only one is now left. The agency has plans for another 11-second hypersonic flight, this time at 10 times the speed of the sound. The Hyper-X broke the record because
