In science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.
A useful theory, in addition to explaining past observations, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.
Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said; " Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house. " Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses.
In a way, any hypothesis is a leap into the unknown. It extends the scientist’s thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories. [br] Bricks are mentioned in the 3rd paragraph to indicate how______.
选项
A、mathematicians approach science
B、building a house is like performing experiments
C、science is more than a collection of facts
D、scientific experiments have led to improved technology
答案
C
解析
本题是细节题。根据关键词bricks在原文找到其定位原句,即第三段的“Science is built with facts just as a house is built with bricks…”(科学是由事实构成的,就像房屋是由砖建成的。但是事实堆积起来并不能成为科学,这比用砖块搭房子复杂得多。)因此说科学并不是简单的堆砌事实。所以可判断C正确。
