[A] The Need for Science[B] The Methods of Science[C] The Challenge of Unsolved Problems[D] The Specific Features of the Laws of Science[E] The Steps in Establishing a Scientific Theory[F] The Rapid Increase of Scientific KnowledgeIt is the business of the scientist to accumulate knowledge about the universe and all that is in it. and to find. if he is able. common factors which underlie and account for the facts that he knows. He chooses, when he can, the method of the "controlled experiment".41. ______.In the course of his inquiries the scientist may find what he thinks is one common explanation for an increasing number of facts. The explanation, if it seems consistently to fit the various facts, is called a hypothesis. If a hypothesis continues to stand the test of numerous experiments and remains unshaken, it becomes a law.42. ______.The "laws" of science differ from the "laws" of a country in two ways. First, a scientific law is liable at any time to need modifying. This happens when a fact is discovered which seems to contradict what the "law" would lead one to expect. The "law" may, in fact. have to be abandoned altogether. Second. a scientific "law" says, "This is likely to be the explanation", or "This accounts for the facts as far as we know them". But the "law" of the country says, "You must..." or "You must not..." The scientific "law" has no moral force; it is not binding on human behavior nor approved or opposed by human conscience.43. ______.The evidence as to the vastness of the universe and the complexity of its arrangements continues to grow at an amazing rate. The gap between what we know and all that can be known seems not to diminish, but rather to increase with every new discovery. Fresh unexplored regions are forever opening out. The rapidity of the growth of scientific knowledge, in the nineteenth and twentieth centuries, is apt to give students and teachers the impression that no sooner is a problem stated than the answer is forthcoming. A more detailed study of the history of science corrects the impression that fundamental discoveries are made with dramatic suddenness. Even in our present age no less than fifty years separate the discovery of radioactivity from the explosion of the first atomic bomb. The teacher, giving his brief accounts of scientific discovery, is apt to forget the long periods of misunderstanding, of false hypotheses and general uncertainty, which almost invariably precede the clear statement of scientific truth.44. ______.The vast mass of information which scientists have gained has provided the answer to the fundamental questions which, through the centuries, have puzzled and sometimes tortured the human mind. There are many such questions. The study of parasites has provided evidence that organisms which could be self-supporting have become parasites, but hardly any light has been shed on the problem of why they should have done so. What enables an organism to respond to the poisonous secretions of harmful bacteria and organize its resources to defend its life45. ______.To raise the standard of living in any country, two things are required, scientific knowledge, and a population sufficiently educated to understand how to apply it. Without the latter, the expected benefits will not come.Notes: ado 麻烦,忙乱。be binding on 对......有约束力。parasite 寄生虫。shed light on 使某事物更清楚些。 secretion 分泌物。 47
