【单选题】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 inter-living, 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.

Just thirty years ago we call it a biological revolution when the fantastic geometry of theDNA、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 imagining.
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.
WhatCANNOT be inferred from the first paragraphA．For three hundred years there have been people holding a hostile attitude toward science.

B、Scientific experiments in the past three hundred years have produced many valuable items.
C．Some people think three hundred years is not long enough to set back for critical appraisal of scientific methoD、
D．Modern civilization depends on science so man supports scientific progress unanimously.
