单选题{{B}}Text 3{{/B}} Astronaut Jim Voss has enjoyed many memorable moments in his career, including three spaceflights and one space walk. But he recalls with special fondness a decidedly earthbound (为地球引力所束缚的) experience in the summer of 1980 when he participated in the NASA-ASEE 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 seal 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(热力学的) 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 a 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."

单选题{{B}}Text 3{{/B}} One of the earliest changes experienced by newly modernizing countries is the reduction of infectious disease through the diffusion of public health technology. Public health technology lowers the death rate, especially among infants and children, causing rapid population growth. Since most of the people of less developed nations live in rural areas that cannot absorb the increased population, unemployment presses people off the land. They tend to migrate into urban areas where newly developing industry and commerce and modern consumer goods and services offer hope for employment and a better life. Unfortunately, the opportunities are more apparent than real; and often the transition is more painful than pleasant. In the courses of the transition from agrarian life to modern urban living, the family undergoes major changes in function, structure, relations, and style. Functionally the family changes from a production unit to a consumption unit. No longer is there need for a large multi-worker household to operate the family's farm interests, and the extended family household changes to the one containing only a core nuclear family. In the city children become economic liabilities rather than economic assets, and eventually families have fewer of them. {{U}}{{B}}Wives lose their functions as producers and maintainers of the labor force{{/B}}{{/U}} and become free to pursue extra household activities. The modern economy forces work outside the home away from kinfolk. Not only the father but also the mother is forced into the marketplace or factory to obtain enough money for the family to survive in a pecuniary economy. Without the extended family household, no one remains at home to supervise children, so they are left on their own. They may be sent into the streets to earn money. Daily life becomes filled with more secondary than primary relations. There is an erosion of family control over individual members. Scarce urban housing forces overcrowding in both dwelling and neighborhood. Dense structures with common halls, stairways, and utilities cause more intensive contact with neighbors than in rural villages. Loss of rural courtyards, over rooms, and large family areas drives group activities such as cooking, eating, and sitting into small rooms or city streets. More positively, household furnishings change as families are able to acquire the high-status accoutrements of modern living such as kerosene burners for cooking ( replacing dung cakes) and beds (instead of mats).

单选题{{B}}Text 1{{/B}} It was fifteen past nine as Marie hurried into the office building where she was going to work. Her bus had inched along through heavy morning traffic, making her a few minutes late for her very first job. She decided to start out half an hour earlier the next day. Once inside the lobby, she had to stand at the elevators and wait several minutes before she could get on one going to the sixth floor. When she finally reached the office marked "Smith Enterprises", she knocked at the door nervously and waited. There was no reply. She tapped on the door again, but still there was no answer. From inside the next office, she could hear the sound of voices, so she opened the door and went in. Although she was sure it was the same office she had been in two weeks before when she had the interview with Mr. Smith, it looked quite different now. In fact, it hardly looked like an office at all. The employees were just standing around chatting and smoking. In the front of the room, somebody must have just told a good joke, she thought, because there was a loud burst of laughter as she came in. For a moment she had thought they were laughing at her. Then one of the men looked at his watch, clapped his hands and said something to the others. Quickly they all went to their desks and, in a matter of seconds, everyone was hard at work. No one paid any attention to Made. Finally she went up to the man who was sitting at the desk nearest to the door and explained that this was her first day in the office. Hardly looking up from his work, he told her to have a seat and wait for Mr. Smith, who would arrive at any moment. Then Made realized that the day's work in the office began just before Mr. Smith arrived. Later she found out that he lived in Connecticut and came into Manhattan on the same train every morning, arriving in the office at 9:35,so that his staff knew exactly when to start working.
