单选题Directions: There are 10 blanks in the following passage. For each numbered blank, there are 4 choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center. Older female managers are {{U}}(51) {{/U}} that working under the {{U}}(52) {{/U}} of younger female managers can be particularly {{U}}(53) {{/U}}. While older women generally have long accepted the {{U}}(54) {{/U}} of working for younger men, some are having difficulty in coming to grips with the idea that younger women are occupying more and more {{U}}(55) {{/U}} positions. Today, nearly 1.5 million women under the age of thirty-five hold managerial jobs, up from 322,000 in the early 1970s. On one hand, this {{U}}(56) {{/U}} signals improvement in the status of career-minded women. On the other hand, it can stifle progression and lead to dissatisfaction. Older women tend to be deferential (恭敬的，恭顺的) with coworkers and maternal with supervisors. Such {{U}}(57) {{/U}} can infuriate young female executives and can {{U}}(58) {{/U}} stressful working conditions. Conflict often arises because older workers frequently feel that they wow how things ought to be {{U}}(59) {{/U}}. Their advice is sought in some cases, but most of the time they are perceived as a {{U}}(60) {{/U}} of the "problem" by younger, career-oriented female managers.

单选题 The concept of the family is difficult to define. Part of the difficulty is that in everyday language, the term family is used to describe a number of relationships. These range from the biological, nuclear family of mother, father, and child and siblings, to the more extended family which includes several generations of blood relatives or relatives through marriage, to close and intimate friends, even to humankind, or the "family of man." The wide variation in everyday usage is less apparent in formal definitions, but even here there is a lack of consensus. Formal definitions do not always fit informal definitions. The U.S. Bureau of the Census, which collects information used by social scientists, defines family as "a group of two or more person related by blood, marriage, or adoption and residing together in a household." A household is comprised of "all persons who occupy a housing unit, that is, a house, an apartment, or other group of rooms, or a single room that constitutes separate living quarters." This definition considers the family in terms of only its structure and legal status, not the qualities of the relationship or its functions or activities. The Census Bureau thus would accept as a family two legally related people who hated each other and were just living together for their mutual economic advantage. Their definition also includes sexual and nonsexual relations; married women and men living together in sexual unions are families, but so are brothers and sisters living together in nonsexual unions. Many social scientists often distinguish between the family of origin and the family of procreation (生殖，生产). Most of us are simultaneously members of two families: the family of origin, into which we are born and of which we are always considered a member, even if we leave it, and the family of procreation, which we join as adults for the purpose of procreation and rearing children. Some social scientists also distinguish marriage from family and see the two as independent of one another. They argue that the family can exist regardless of whether the couple is married. They see marriage as a public ceremony which joins together two kinship groups and in so doing lays out some important rights over children, domestic authority, and sexual matters. Marriage is also the ritual through which children are made legitimate in the eyes of the parents and the society. Marriage therefore is a social ceremony, whereas family need not be.

单选题{{B}}Passage Three{{/B}} For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic (国家主义的). Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U. S. had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms (隐约出现) as humanity's next great terra incognita (未探明之地). And with growing emphasis on international cooperation in large space ventures, it is clear that imperatives (需要，必要) other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across inter- planetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
