For about three centuries we have been doing science, trying science out, us

问题     For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human development long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.
    Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day these days on the issue of nuclear energy. Give it back, say some of the voices, it doesn’t really work, we’d tried it and it doesn’t work, go back three hundred years and start again on something else less chancy for the race of man. The principal discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty—Newtonian mechanics, for example—have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.
    Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today’s imagination.
    It is not just that there is more to do, there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves. [br] What can’t be inferred from the first paragraph?

选项 A、Many valuable items were produced in the past.
B、Man supports scientific progress unanimously.
C、Some held hostile attitude toward science in the past.
D、Three hundred years is not long enough in science.

答案 B

解析 细节题。第一段谈的是在过去的300年里,人们不断地研发、尝试和利用科学,以此建立起了现代文明,[A]符合文意;每一项的发明都需要一系列科学实验,每一种促进人类进步的新途径都需要长时间的验证讨论后方可达成一致,也就是说,人类在支持科学进步上并不是统一的,[B]与文意不符,故为答案;根据文中“…critical appraisal of the scientific method,”可柞出[C];根据第三句和第四句可推出[D]。
