• Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound experience in the summer of 1980, when he participated in the NASA-AS-EE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point, was assigned to the Marshall Space Flight Center"s propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seals could have led to destructive results for the astronauts who relied on them."I worked a bit with NASA engineers," says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic analysis. "At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall, summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status.It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1978. Over the next nine years he reapplied repeatedly, and was finally accepted in 1987. Since then he has participated in three space missions. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000.Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes link with our colleges and universities," Voss explains. "There"s an exchange of information and an exchange of perspectives that is very important."For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom. "Why was the hydraulic fuel pump seal important for the space shuttle？
  A．Because previous seals all failed.B．Because it was very complex in running the space program.C．Because great care has to be taken of the hydraulic fuel pump sealing.D．Because any crack in the seals would cause disastrous results for the astronauts.

• Are burgers and fries a product of the profound social changes of the past 50 years, or were they to a large extent responsible for them？ The author of this diatribe against multinational restaurant brands opts for the latter explanation. "There is nothing inevitable about the fast food nation that surrounds us", he concludes. "The triumph of McDonald"s and its imitators was by no means pre-ordained". But it happened nevertheless and in his view, it is to be blamed for many of the evils of modern America and their global spread. The emergence of the corporate colossus, followed inexorably by its deionization, is a familiar pattern in American business history.The modern phenomenon of fast food originated in California just before the Second World War. Its first manifestation was kerb service, with meals delivered to motorists by handsome young carhops. Richard and Maurice McDonald, who ran a drive-in burger bar in San Bernardino near Los Angeles, became tired of having constantly to replace their carhops and wash up crockery and dishes. In 1948 they decided to make customers serve themselves, while restricting the menu to items that could be prepared by unskilled cooks and eaten without plates, knives or forks.The McDonald brothers were soon bought out by the entrepreneurial Ray Kroc, who franchised their name and techniques so successfully that there is now scarcely a comer of the world that is free from their trademark golden arches, invariably spawning a cluster of rival chains selling hamburgers, pizzas, or fried chicken, handed out by smiling teenagers willing to accept minimal pay. They are cheap, cheerful, popular, and children love them. So just what is Mr. Schlosser"s beef？ Apart from his nutritional reservations—too much fat, salt and sugar—he proves how. as the chains expanded, they were able to dictate terms to the suppliers of potatoes and ground beef, their staple ingredients. This caused an upheaval in agribusiness, as a few large suppliers quickly forced less efficient producers out of the market. The drive to keep down costs and increase the speed of production led to the employment of cheap unskilled labor and. to the widespread toleration of dangerous and unhygienic practices among growers and processors, which regulatory bodies have failed to police.Mr. Schlosser, who is a skillful and persuasive investigative reporter, sees all this as a damaging corruption of the free market. He is especially angered by promotional techniques aimed at impressionable children. A 1997 giveaway of Teenie Beanie Babies increased the sale of McDonalds" Happy Meals from 10m a week to 10m a day. And a survey found that 96% of American schoolchildren could identify Ronald McDonald, the chain"s mascot. Only Santa Claus scored higher.From the example of McDonald the author concludes that______.
  A．the fast food is the great social change of the past 50 yearsB．the success of multinational brands was destinedC．the corporate deionization contributed to some social changesD．McDonald is popular in America
