{{B}}Directions:{{/B}}
Read the following text carefully and then translate the underlined segments intoChinese.
Your translation should be written clearly onANSWER SHEET 2.
(46) {{U}}A、recent phenomenon in present-day science and technology is the increasing trend towards "directed" or "programmed" research; i.e. research whose scope and objectives are predetermined by private or government organizations rather than researchers themselves.{{/U}}Any scientist working for such organizations and investigating in a given field therefore tends to do so in accordance with a plan or program designed beforehanD、
At the beginning of the century, however, the situation was quite different.At that time there were no industrial research organizations in the modern sense: the laboratory unit consisted of a few scientists at the most, assisted by one or two technicians. 47) {{U}}Nevertheless, the scientist, often working with inadequate equipment in unsuitable rooms, was free to choose any subject for investigation he liked, since there was no predetermined program to which he had to conform.{{/U}}
48) {{U}}As the century developed, the increasing magnitude and complexity of the problems to be solved made it impossible, in many cases, for the individual scientist to deal with the huge mass of new data, techniques and equipment that were required for carrying out research accurately and efficiently.{{/U}} The increasing scale and scope of the experiments needed to test new hypotheses and develop new techniques and industrial processes led to the setting up of research groups or teams using highly-complicated equipment in elaborately-designed laboratories. 49) {{U}}Owing to the large sums of money involved, it was then felt essential to direct these human and material resources into specific channels with clearly-defined objectives.{{/U}} In this way it was considered that the quickest and most practical results could be obtaineD、This, then, was programmed (programmatic) research,
One of the effects of this organized and standardized investigation is to cause the scientist to become increasingly involved in applied research (development), especially in the branches of science which seem most likely to have industrial applications. Private industry and even government departments tend to concentrate on immediate results and show comparatively little interest in long-range investigations. 50) {{U}}In consequence, there is a steady shift of scientists from the pure to the applied field, where there are more jobs available, frequently more highly-paid and with better technical facilities than jobs connected with pure research in a university.{{/U}}
Owing to the interdependence between pure and applied science, it is easy to see that this system, if extended too far, carries considerable dangers for the future of science--and not only pure science, but applied science as well. (409 words)

7题:Do students learn from programmed instruction The research leaves us in no doubt of this. They do, indeed, learn. 46. Many kinds of students learn -- college, high school, secondary, primary, preschool, adult, professional, skilled labor, clerical employees, military, deaf, retarded imprisoned- every kind of students that programs have been tried on. Using programs, these students are able to learn mathematics and science at different levels, foreign languages,English language correctness, spelling, electronics, computer science, psychology, statistics, business skills, reading skills, instrument flying rules, and many other subjects; the limits of the topics which can be studied efficiently by means of programs are not yet known.
For each of the kinds of subject matter and the kinds of student mentioned above, experiments have demonstrated that a considerable amount of learning can be derived from programs; this learning has been measured either by comparing pre-and post-tests or the time and trials needed to reach a set criterion of performance. 47. But the question, how well do students learn from programs as compared to how well they learn from other kinds of instruction, we cannot answer quite confidently.
Experimental psychologists typically do not take very seriously the evaluative experiments in which learning from programs is compared with learning from conventional teaching. Such experiments are doubtlessly useful, they say, for school administrators or teachers to prove to themselves (or their boards of education) that programs work. 48. But whereas one can describe fairly well the characteristics of a program, can one describe the characteristics of a classroom teaching situation so that the result of the comparison will have any generality What kind of teacher is being compared to what kind of program Furthermore, these early evaluative experiments with programs are likely to suffer from the Hawthorne effect; that is to say, students are in the spotlight when testing something new, and are challenged to do well. 49. It is very hard to make allowance for this effect; therefore, the evaluative tests may be useful administratively, say many of the experiments, but do not contribute much to science, and should properly be kept for private use.
These objections are well taken.And yet, do they justify us in ignoring the evaluative studies The great strength of a program is that it permits the student to learn efficiently by himself. 50. Is it not therefore important to know how much and what kind of skills, concepts, insights, or attitudes he can learn by himself from a program as compared to what he can learn from a teacher Admittedly, this is a very difficult and complex research problem, but that should not keep us from trying to solve it.
