阅读下面短文 根据所读内容在表格中的空白处填入恰当的单词。 注意:每个空格只填一个单词。 The word science is heard so often in modern times that almost everybody has an idea of its meaning. However its definition is difficult for many people. The meaning of the term is confusing but everyone should understand its meaning and objectives (目标). Just to make the explanation as simple as possible suppose science is defined as classified knowledge or facts. Even in the true science distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example hypotheses(假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion. The objectives of science are primarily the discovery and later the understanding of the unknown. Man cannot be satisfied with recognizing that secrets existing in nature of those questions are unanswerable; he must solve them. Toward that end specialists in the field of biology and related fields of interest are directing much of their time and energy. Actually two basic approaches lead to the discovery of new information. One aimed at satisfying curiosity is referred to as pure science. Sometimes practicalminded people miss the point of pure science in thinking only of its immediate application for economic rewards. However one should remember that the construction of the microscope had to come before the discovery of the cell. The scientists devoting their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied. The other is aimed at using knowledge for specific purposes-for instance improving health raising standards of living or creating new consumer products. In this case knowledge is put to economic use. Such an approach is referred to as applied science.
