单选题 There are great careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in a great area at a glance, people who perhaps know too much about any one field. There is, in other words, a demand for people Who are capable of seeing the forest rather than the trees, of making general judgments. And these "generalists" are particularly needed for positions in administration, where it is their job to see that other people do the work, where they have to plan for other people, to organize other people' s work, to begin it and judge it. The specialist understands one field; his concern is with technique and tools. He is a "trained" man; and his educational background is properly technical or professional. The generalist-and especially the administrator-deals with people; his concern is with leadership, with planning, and with direction giving. He is an "educated" man; and the humanities are his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in a particular field. Any organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly. Your first job may turn out to be the right job for you-but this is a pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.

单选题The history of modern pollution problems shows that most have resulted from negligence and ignorance. We have an appalling tendency to interfere with nature before all of the possible consequences of our actions have been studied in depth. We produce and distribute radioactive substances, synthetic chemicals and many other potent compounds before fully comprehending their effects on living organisms. Our education is dangerously incomplete. It will be argued that the purpose of science is to move into unknown territory, to explore, and to discover. It can be said that similar risks have been taken before, and that these risks are necessary to technological progress. These arguments overlook an important element. In the past, risks taken in the name of scientific progress were restricted to a small place and brief period of time. The effects of the processes we now strive to master are neither localized nor brief. Air pollution covers vast urban areas. Ocean pollutants have been discovered in nearly every part of the world. Synthetic chemicals spread over huge stretches of forest and farmland may remain in the soil for decades and years to come. Radioactive pollutants will be found in the biosphere for generations. The size and persistence of these problems have grown with the expanding power of modern science. One might also argue that the hazards of modern pollutants are small compared with the dangers associated with other human activity. No estimate of the actual harm done by smog, fallout, or chemical residues can obscure the reality that the risks are being taken before being fully understood. The importance of these issues lies in the failure of science to predict and control human intervention into natural processes. The true measure of the danger is represented by the hazards we will encounter if we enter the new age of technology without first evaluating our responsibility to environment.

单选题Teaching children to read well from the start is the most important task of elementary schools. But relying on educators to approach this task correctly can be a great mistake. Many schools continue to employ instructional methods that have been proven ineffective. The staying power of the "look-say" or "whole-word" method of teaching beginning reading is perhaps the most flagrant example of this failure to instruct effectively. The whole-word approach to reading stresses the meaning of words over the meaning of letters, thinking over decoding, developing a sight vocabulary of familiar words over developing the ability to unlock the pronunciation of unfamiliar words. It fits in with the serf-directed, "learning how to learn" activities recommended by advocates of "open" classrooms and with the concept that children have to be developmentally ready to begin reading. Before 1963, no major publisher put out anything but these "Run- Spot-Run" readers. However, in 1955, Rudolf Flesch touched off what has been called "the great debate" in beginning reading. In his best-seller Why Johnny Can't Read, Flesch indicted(控诉)the nation's public schools for miseducating students by using the look-say method. He said-and mere scholarly studies by Jeane Chall and Rovert Dykstra later confirmed-that another approach to beginning reading, founded on phonics(声学), is far superior. Systematic phonics first teaches children to associate letters and letter combinations with sounds; it then teaches them how to blend these sounds together to make words. Rather than building up a relatively limited vocabulary of memorized words, it imparts a code by which the pronunciations of the vast majority of the most common words in the English language can be learned. Phonics does not devalue the importance of thinking about the meaning of words and sentences; it simply recognizes that decoding is the logical and necessary first step.
