单选题As many as one in four U.S. workers may be chronically angry on the job, with angry employees also more likely to be bored, have low energy and feel "stuck" in their posts, according to a report Tuesday. Employees are most likely to be angered by a boss or supervisor by a fellow employee or by others in the workplace not being productive, by tight deadlines or by heavy workloads, said Donald Gibson, a professor at the Yale School of Management. "A turbulent economic environment that has produced, on the one hand, productivity and growth and, on the other, wrenching change and uncertainty, has buffeted the workplace," the report said. "While a majority of employees are responding to these conditions with reports of workplace satisfaction there remain a substantial portion who are dissatisfied, even angry, at work," it added. "Most visibly, anger is linked to workplace aggression, which appears to be increasing: We are weekly confronted with stories of workers taking aggressive, even violent, action particularly against supervisors." The survey found that 25 percent of those contacted said they were at least somewhat angry at work on a continuing basis. Angry employees tend to have less energy and interest in the job, and tend also to be bored, according to Gibson. And angry employees tend to feel "stuck" in the job. The study did not speculate on what percentage of angry workers are likely to resort to violence. It did find that they feel less loyal to an employer. There have been a number of workplace shootings in the United States over the years, most recently rampages in Georgia and Alabama which left 12 dead.

单选题Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of PhDs. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter of expert guessing. Last week a well-rounded study was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless. The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph.D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates. Discussing the study last week, Dr. Tucker said the project was initiated because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph.D. programs were capable of competing the requirement for the degree. Attrition at the Ph.D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of highly trained specialists and college teachers could be reduced by persuading the dropouts to return to graduate schools to complete the Ph.D. "The results of our research," Dr. Tucker concluded, "did not support these opinions." 1. Lack of motivation was the principal reason for dropping out. 2. Most dropouts went as far in their doctoral program as was consistent with their levels of ability or their specialities. 3. Most dropouts are now engaged in work consistent with their education and motivation. Nearly 75 per cent of the dropouts said there was no academic reason for their decision, but those who mentioned academic reason cited failure to pass the qualifying examination, uncompleted research and failure to pass language exams. Among the single most important personal reasons identified by dropouts for non-completion of their Ph.D. program, lack of finances was marked by 19 per cent. As an indication of how well the dropouts were doing, a chart showed 2% in humanities were receiving $20,000 and more annually while none of the Ph. D."s with that background reached this figure. The Ph. D."s shone in the $7,500 to $15,000 bracket with 78% at that level against 50% for the dropouts. This may also be an indication of the fact that top salaries in the academic fields, where Ph. D."s tend to rise to the highest salaries, are still lagging behind other fields. As to the possibility of getting dropouts back on campus, the outlook was glum. The main condition which would have to prevail for at least 25% of the dropouts who might consider returning to graduate school would be to guarantee that they would retain their present level of income and in some cases their present job.

单选题{{B}}Directions:{{/B}} Answer all the questions based on the information in the passages below.{{B}}Passage One{{/B}} Early that June Pins XII secretly addressed the Sacred College of Cardinals on the extermination of the Jews. "Every word we address to the competent authority on this subject, and all our public utterances," he said in explanation of his reluctance to express more open condemnation, "have to be carefully weighed and measured by us in the interest of the victims themselves, lest, contrary to our intentions, we make their situation worse and harder to bear." He did not add that another reason for proceeding cautiously was that he regarded Bolshevism as a far greater danger than Nazism.The position of the Holy Sea was deplorable but it was an offense of omission rather than commission. The Church, under the Pope's guidance, had already saved the lives of more Jews than all other churches, religious institutions, and rescue organizations combined, and was presently hiding thousands of Jews in monasteries, convents, and Vatican City itself. The record of the Allies was far more shameful. The British and Americans, despite lofty pronouncements, had not only avoided taking any meaningful action but gave sanctuary to few persecuted Jews. The Moscow Declaration of that year—signed by Roosevelt, Churchill, and Stalin—methodically listed Hitler's victims as Polish, Italian, French, Dutch, Belgian, Norwegian, Soviet, and Cretan. The curious omission of Jews (a policy emulated by the U. S. Office of War Information) was protested vehemently but uselessly by the World Jewish Congress. By the simple expedient of converting the Jews of Poland into Poles, and so on, the Final Solution was lost in the Big Three's general classification of Nazi terrorism.Contrasting with their reluctance to face the issue of systematic Jewish extermination was the forthrightness and courage of the Danes, who defied German occupation by transporting to Sweden almost every one of their 6,500 Jews; of the Finns, allies of Hitler, who saved all but four of their 4,000 Jews; and of the Japanese, another ally, who provided refuge in Manchuria for some 5,000 wandering European Jews in recognition of financial aid given by the Jewish firm of Kuhn, Loeb & Company during the Russian-Japanese War of 1904～1905.

单选题Many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance were determined by technologists, artisans, designers, inventors, and engineers using nonscientific modes of thought. Many features and qualities of the objects that a technologist thinks about can't be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process. In the development of Western technology, it has been nonverbal thinking, by and large, that has fixed the outlines and filled in the details, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them. The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of non-verbal thinking on the machine by continually using an intuitive sense of rightness and fitness. What would be the shape of the combustion chamber? Where should be the valves placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary. Design courses, then, should be an essential element in engineering curricula. Nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed, to entail "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools. If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to en- counter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.
