Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu.

| 第5题：It has been said that management is a science and that leadership is an art. Management is comprised of concrete, measurable skills: planning, organizing, directing, and controlling. Thumb through any management textbook and you’ll see specific models, formulas, procedures, or techniques for monitoring andControlling performance Output.Controlling productivity through adherence to standards is the stock-in-trade of the effective manager. It’s not always an easy task, and talented managers should be given the credit they deserve in helping their organizations succee D、No organization can survive for very long, let alone earn any sort of substantial profits, without sound management.But management alone is not enough in today’s marketplace. It is the right balance, a combination of efficient management and leadership, that every organization is seeking. Just what is the new model of leadership for the 21st century It revolves around five abstract qualities. Managers may possess some or all of these abilities to one degree or another, but these skills are distinct from the particular qualities that define management. To better understand how leadership and management differ, let’s review the five leadership competencies. Self-mastery is the foundation upon which a leader’s credibility is built and from which a leader’s image will evolve. Self-mastery involves awareness, acknowledgment, and acceptance. It’s about discovering the qualities that make you special and unique. It’s about your own talents and abilities--your personal areas of excellence.Effective leaders create opportunities to showcase their natural abilities. They uncover their potential talents by continually stretching themselves and pushing themselves to their limits.At the same time, however, the successful leader acknowledges his or her limitations. To achieve true self-mastery you must accept yourself, including your faults, totally and unconditionally. Vision is in many ways the heart and soul of leadership. While the manager must deal with issues and produce results on a day-to-day basis, a leader must focus on both the present and the future. The manager’s concern is today; the leader has a vision for tomorrow.But simply having a vision is not enough: you must make others believe in it, too. Put your plans for the future before the eyes and ears of the people around you. When other people begin to buy into your vision and make it their own, good things start to happen—and happen quickly. Leaders turn their vision into reality by constantly letting others know what’s in it for them. "Personal power" is the ability to influence and persuade others. It is not to be confused with “position power”. Position power is embedded in hierarchical, organizational structure. Personal power is earne D、You do not necessarily need to have direct authority over others to display personal power. In fact, in the most successful companies, leadership exists at all levels.Develop personal power by being dependable, following through on commitments, and demonstrating concern for the welfare of others. People will recognize your personal power and look to you for direction. Empowerment completes the set of leadership skills.Although it has become a buzz word in the 90’s, leaders have been aware of the concept of empowerment throughout the ages.Empowerment is the process by which a leader enables other individuals to successfully complete a certain job or task. It is a technique that allows you to delegate responsibility for tasks throughout your organization, even at the lowest levels.As a leader, it is in your interest to nurture and develop individuals who will one day take your place, so make empowerment a top priority.Empowerment involves three critical ingredients: skills, confidence, and authority.Evaluate your followers’ skills and provide training to improve or enhance their abilities. Instill confidence in others and raise th |

| 第7题：W—12是一种严重危害谷物生长的病毒，每年要造成谷物的大量减产。科学家们发现，把一种从W—12中提取的基因，植入易受其感染的谷物基因中，可以使该谷物产生对W—12的抗体，从而大大减少损失。 以下各项如果为真，都能加强上述结论，除了： A．经验证明，在同一块土地上相继种植两种谷物，如果第一种谷物不易感染某种病毒，则第二种谷物通常也如此。 B．病毒的感染能力越强，则其繁衍越强；反之，则越弱。 C．植物通过基因变异获得的抗体会传给后代。 D．植物通过基因变异获得对某种病毒的抗体的同时，会增加对其他某些病毒的抵抗力。 E．植物通过基因变异获得对某种病毒的抗体的同时，会改变其某些生长特性。 |

Is it an inescapable fact that the older you get, the {{U}} (23) {{/U}} you remember Well, sort of.But as time goes by, we tend to blame age {{U}} (24) {{/U}} problems that are not necessarily age-relateD、 "When a teenager can’t find her keys, she thinks it’s because she’s distracted or disorganized," says Paul Gold "A、70-year-old blames her {{U}} (25) {{/U}}." In fact, the 70-year-old may have been {{U}} (26) {{/U}} things for decades. In healthy people, memory doesn’t worsen as {{U}} (27) {{/U}} as many of us think. "As we {{U}} (28) {{/U}} , the memory mechanism isn’t {{U}} (29) {{/U}}," says psychologist FergusCraik. "It’s just inefficient."

| 第9题：Over the past century, all kinds of unfairness and discrimination have been condemned or made illegal.But one insidious form continues to thrive: alphabetism. This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames begin with a letter in the lower half of the alphabet. It has long been known that a taxi firm calledAAAA、cars has a big advantage over Zodiac cars when customers thumb through their phone directories. Less well known is the advantage thatAdamAbbott has in life over Zoe Zysman.English names are fairly evenly spread between the halves of the alphabet. Yet a suspiciously large number of top people have surnames beginning with letters betweenA、and K. Thus theAmerican president and vice-president have surnames starting withB、andC、respectively; and 26 of GeorgeBush’s predecessors (including his father) had surnames in the first half of the alphabet against just 16 in the second half.Even more striking, six of the seven heads of government of the G7 rich countries are alphabetically advantagedBerlusconi,Blair,Bush,Chirac,Chretien and Koizumi). The world’s three top central bankers (Greenspan,Duisenberg and Hayami) are all close to the top of the alphabet, even if one of them really uses Japanese characters.As are the world’s five richest men (Gates,Buffett,Allen,Ellison andAlbrecht). Can this merely be coincidence One theory, dreamt up in all the spare time enjoyed by the alphabetically disadvantaged, is that the lot sets in early.At the start of the first year in infant school, teachers seat pupils alphabetically from the front, to make it easier to remember their names. So short-sighted Zysman junior gets stuck in the back row, and is rarely asked the improving questions posed by those insensitive teachers.At the time the alphabetically disadvantaged may think they have had a lucky escape. Yet the result may be worse qualifications, because they get less individual attention, as well as less confidence in speaking publicly. The humiliation continues.At university graduation ceremonies, theABCs proudly get their awards first; by the time they reach the Zysmans most people are literally having a ZZZ. Shortlists for job interviews, election ballot papers, lists of conference speakers and attendees: all tend to be drawn up alphabetically, and their recipients lose interest as they plough through them. What can we infer from the first three paragraphs A、In bothEast and West, names are essential to success. B、The alphabet is to blame for the failure of Zoe Zysman. C、Customers often pay a lot of attention to companies’ names. D、Some form of discrimination is too subtle to recognize. |
