单选题In every major city in America, commuters are spending more and more time in their cars fighting traffic. The Texas Transportation Institute recently reported that the average commuter spends an extra 46 hours--more than a full workweek--each year caught in traffic. A major source of the congestion is freight trucks. One large truck takes up the space of almost four cars, and the average truck is becoming longer, with more use of double-and triple-trailers. Increases in truck volume, obviously, add to commuting problems, and according to the U. S. Department of Transportation, freight volume is expected to increase by two-thirds over the next 20 years. One proposed solution--building new roads--is expensive and politically contentious. But there's another way: greater use of freight rail. One freight train can carry the cargo of 500 trucks, and one intermodal train can carry nearly 300 truck trailers. Trucking companies and railroads already are forming intermodal partnerships that combine the best of both kinds of transportation. In an urban area like New York, shifting 25% of freight from trucks to freight trains by the year 2025 would reduce drivers' commuting time by 52.9 hours. In addition, such a shift would save $734 per household in annual congestion costs. Shifting freight from road to rail also helps the environment. Freight rail is more fuel-efficient per ton-mile than trucks. And it reduces drivers' fuel consumption by decreasing the time they spend idling in traffic. By 2025, commuters in New York could save 254 gallons of fuel with a 25% shift of freight from truck to rail. Air pollution levels also would improve with an increase in the use of freight rail. For instance, that same 25% shift to rail by 2025 would decrease air pollutants New York by as much as 79,500 tons. To carry out these changes, the freight rail industry will need more capacity, but that depends on return on investments. Because railroads are not meeting their cost of capital, government policymakers may want to consider investment incentives to help meet the growing demand for freight rail. This would enable freight railroads to provide convenient, on-time, quality service to shippers and boost their share of freight transport. It is hard to imagine a less costly or more effective strategy for reducing traffic congestion.

单选题In old days, when a glimpse of stocking was looked upon as something far too shocking to distract the serious work of an office, secretaries were men. Then came the first World War and the male secretaries were replaced by women. A man's secretary became his personal servant, charged with remembering his wife's birthday and buying her presents; taking his suits to the dry-cleaners; telling lies on the telephone to keep people he did not wish to speak to at bay and, of course, typing and filing and taking shorthand. Now all this may be changing again. The microchip and high technology is sweeping the British office, taking with it much of the routine clerical work that secretaries did. "Once office technology takes over generally, the status of the job will rise again because it will involve only the high-powered work and then men will want to do it again." That was said by one of the executives (male) of one of the biggest secretarial agencies in this country. What he has predicted is already under way in the US. One girl described to me a recent temporary job placing men in secretarial jobs in San Francisco. She noted that all the men she dealt with appeared to be gay so possibly that it was just a new twist to the old story. Over here, though, there are men coming onto the job market as secretaries. Classically, girls have learned shorthand and typing and gone into a company to seek their fortune from the bottom-and that's what happened to John Bowman. Although he joined a national grocery chain as secretary to its first woman senior manager, he has since been promoted to an administration job. "I filled in the application form and said I could do audio/typing, and in fact I was the only applicant. The girls were reluctant to work for this young, glamorous new woman with all this power in the firm." "I did typing at school, and then a commercial course. I just thought it would be useful finding a job. I never got any funny treatment from the girls, though I admit I've never met another male secretary. But then I joined the Post Office as a clerk and carelessly played with the typewriter, and wrote letters, and thought that after all secretaries were getting a good ￡21,000 a year more than clerks like me. There was a shortage at that time, you see." "It was simpler working for a woman than for a man. I found she made decisions, she told everybody what she thought, and there was none of that male bitchiness, or that stuff 'ring this number for me dear, ' which men go in for. " "Don't forget, we were a team-that's how I feel about it-not boss and servant but two people doing different things for the same purpose. Once high technology has made the job of secretary less routine, will there be male takeover? Men should beware of thinking that they can walk right into the better jobs. There are a lot of women secretaries who will do the job as well, as they are as efficient and well-trained to cope with word processors and computers as men.

单选题{{B}}Passage 2{{/B}} My parents' house had an attic, the darkest and strangest part of the building, reach- able only by placing a stepladder beneath the trapdoor, and filled with unidentifiable articles too important to be thrown out with the trash but no longer suitable to have at hand. This mysterious space was the memory of the place. After many years all the things deposited in it became, one by one, lost to consciousness. But they were still there, we knew, safely and comfortably stored in the tissues of the house. These days most of us live in smaller, more modern houses or in apartments, and at- tics have vanished. Even the deep closets in which we used to pile things up for temporary forgetting are rarely designed into new homes. Everything now is out in the open, openly acknowledged and displayed, and whenever we grow tired of a memory, an old chair, a trunkful of old letters, they are cast into the dump for burning. This has seemed a healthier way to live, except maybe for the smoke everything out to be looked at, nothing strange hidden under the roof, nothing forgotten because of no place left in impenetrable darkness to forget. Openness is the new lifestyle, no undisclosed belongings, no private secrets. Candor is the rule in architecture. The house is a machine for living, and what kind of machine would hide away its worn-out, deserted parts? But it is in our nature as human beings to clutter, and we long for places set aside, reserved for storage. We tend to accumulate and outgrow possessions at the same time, and it is an endlessly discomforting mental task to keep sorting out the, ones to get rid of. We might, we think, remember them later and find a use for then, and if they are gone for good, off to the dump, this is a source of nervousness. I think it may be one of the reasons we drum our fingers so much these days. We might take a lesson here from what has been learned about our brains in this century. We thought we discovered, first off, the attic, although its existence has been mentioned from time to time by all the people we used to call great writers. What we really found was the trapdoor and a stepladder, and off we clambered, shining flashlights into the corners, vacuuming the dust out of bureau drawers, puzzling over the names of objects, tossing them down to the floor below, and finally paying around fifty dollars an hour to have them cast away for burning.

单选题As children get older, self-discipline should take the place of imposed discipline. Constrains become internalized and children begin to weigh from within the validity of their promptings(敦促). But their tendency to be self-critical, to develop a code of their own, depends on the extent to which they must have kept critical company. The dialogue within reflects the dialogue without that is why discussion is so important during adolescence. Those in authority over children will, therefore, attempt to get children to do what is sensible by appealing to their common sense instead of ordering them around or appealing to their own status. They will not say, "I'm your father and I'm telling you not to smoke," but will point out the dangers involved. It is a further question, however, whether a child's acceptance of good reasons should be the criterion for his action. If a parent explains to a child why it is stupid and wrong to put objects on railway lines, and yet sees him doing so, will he stand aside and reflect that the boy is learning to choose? Parents must weigh their own fundamental principles against what is instructive for their children. Example, of course, is crucial. Parents and others must provide a pattern out of which the child can eventually develop his own style of self-regulation. This is not likely to happen unless exercise of authority is rationalized and sensitively adapted to age, to persons , and to the tasks in hand. For the young will tightly rebel against the irrational expression of a traditional status. In brief, teachers and parents must learn to be in authority without being authoritarian.
