单选题 For most of us, the work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, traveling to and from work. What we do there largely determines our standard of living and to a considerable extent the status we are accorded by our fellow citizens as well. It is sometimes said that because leisure has become more important the indignities and injustices of work can be pushed into a comer, that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustration and humiliations by concentrating their hopes on the other parts of their lives. I reject that as a counsel of despair. For the foreseeable future the material and psychological rewards which work can provide, and the conditions in which work is done, will continue to play a vital part in determining the satisfaction that lie can offer. Yet only a small minority can control the pace at which they work or the conditions in which their work is done; only for a small minority does work offer scope for creativity, imagination, or initiative. Inequality at work and in work is still one of the cruelest and most glaring forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial life, many of which arise directly or indirectly from the frustrations created by inequality at work, unless we tackle it head-on. Still less can we hope to create a decent and humane society. The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning; they are able to exercise responsibility; they have a considerable degree of control over their own and others' working lives. Most important of all, they have opportunity to initiate. By contrast, for most manual workers, and for a growing number of white-collar workers, work is a boring, dull, even painful experience. They spend all their working lives in conditions which would be regarded as intolerable—for themselves—by those who take the decisions which let such conditions continue. The majority have little control over their work; it provides them with no opportunity for personal development. Often production is so designed that workers are simply part of the technology. In offices, many jobs are so routine that workers justifiably feel themselves to be mere cogs in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated from their work and their firm, whether it is in public or in private ownership.

单选题Discoveries in science and technology are thought by "untaught minds" to come in blinding flashes or as the result of dramatic accidents. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. He experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error Innovation is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score. The point is that the players who score most are the ones who take most shots at the goal and so it goes with innovation in any field of activity. The prime difference between innovators and others is one of approach. Everybody gets ideas, but innovators work consciously on theirs, and they follow them through until they prove practicable or otherwise. What ordinary people see as fanciful abstractions, professional innovators see as solid possibilities. "Creative thinking may mean simply the realization that there"s no particular virtue in doing things the way they have always been done," wrote Rudolph Flesch, a language authority, this accounts for our reaction to seemingly simple innovations like plastic garbage bags and suitcases on wheels that make life more convenient: "How come nobody thought of that before?" The creative approach begins with the proposition that nothing is as it appears. Innovators will not accept that there is only one way to do anything. Faced with getting from A to B, the average person will automatically set out on the best-known and apparently simplest route. The innovators will search for alternate courses, which may prove easier in the long run and are bound to be more interesting and challenging even if they lead to dead ends. Highly creative individuals really do march to a different drummer.

In order to solve these problems, some planners believe we should limit the size of our cities, perhaps by restricting population, or perhaps by offering {{U}} {{U}} 17 {{/U}} {{/U}}jobs in the provinces. Others believe that cities cannot be limited in size and that the problems must be solved in a {{U}} {{U}} 18 {{/U}} {{/U}}of ways—by creating green areas, building {{U}} {{U}} 19 {{/U}} {{/U}}houses for everybody, stopping factory pollution, {{U}} {{U}} 20 {{/U}} {{/U}}motor transport, and so on.
