单选题 Specialization can be seen as a response to the problem of an increasing accumulation of scientific knowledge. By splitting up the subject matter into smaller units, one man could continue to handle the information and use it as the basis for further research. But specialization was only one of a series of related developments in science affecting the process of communication. Another was the growing professionalization of scientific activity. No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word 'amateur' does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialization in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur participation in science. The trend was naturally most obvious in those areas of science based especially on a mathematical or laboratory training, and can be illustrated in terms of the development of geology in the United Kingdom. A comparison of British geological publications over the last century and a half reveals not simply an increasing emphasis on the primacy of research, but also a changing definition of what constitutes an acceptable research paper. Thus, in the nineteenth century, local geological studies represented worthwhile research in their own right; but, in the twentieth century, local studies have increasingly become acceptable to professionals only if they incorporate, and reflect on, the wider geological picture. Amateurs, on the other hand, have continued to pursue local studies in the old way. The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the widespread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century. As a logical consequence of this development, separate journals have now appeared aimed mainly towards either professional or amateur readership. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way. Although the process of professionalization and specialization was already well under way in British geology during the nineteenth century, its full consequences were thus delayed until the twentieth century. In science generally, however, the nineteenth century must be reckoned as the crucial period for this change in the structure of science.

单选题Innovation, the effective recipe of progress, has always cost people their jobs. Over the past 30 years the digital revolution has 28 many of the mid-skill jobs that supported 20th-century middle-class life. Typists, ticket agents, bank tellers and many production-line jobs have been 29 with. For those who believe that technological progress has made the world a better place, such change is a natural part of rising 30 . Although innovation kills some jobs, it creates new and better ones, as a more productive society becomes richer and its wealthier inhabitants 31 more goods and services. A hundred years ago one in three American workers was employed on a farm. Today less than 2% of them produce far more food. The millions freed from the land were not delivered to joblessness, but found better-paid work as the economy grew more 32 . Today the pool of secretaries has 33 , but there are ever more computer programmers and web designers. Optimism remains the right starting-point, but for Workers the dislocating (扰乱的) effects of technology may make themselves evident faster than its benefit. Even if new jobs and 34 products emerge, in the short term income gaps will widen, causing huge social dislocation and perhaps even changing politics. Technology's impact will feel like a tornado, hitting the rich world first, but 35 sweeping through poorer countries too. Worse, it seems likely that this wave of technological 36 to the job market has only just started. From driverless cars to clever household devices, innovations that already exist could destroy jobs that have 37 been untouched. A. prosperity E. partition I. conversely M. demand B. dispensed F. eventually J. shrunk N. complicated C. inquire G. sophisticated K. fragile O. hitherto D. wonderful H. displaced L. disruption
