What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answer he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of this mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.
选项
4、The author quotes the case of Albert Einstein to illustrate _______.
A. that measurements are keys to success in science
B. that accuracy of mathematics
C. that the investigations are important in science
D. that the mathematical calculations may test his investigations
答案
C
解析
这是一道态度题。本题询问“作者引用爱因斯坦的例子是为了说明什么?”。通过阅读第二段我们发现,作者在引用爱因斯坦的例子之前谈到一句话,即“This is one reason that investigations are important in science.”。这句话表明,作者引用爱因斯坦的例子就是为了说明调查研究在科学领域的重要性。因此答案应该选择C。
