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
2、“The scientist, however, goes one step further…”. The author says this to show _______.
A. the importance of information
B. the importance of thinking
C. the difference between scientists and ordinary people
D. the difference between carpenters and people with other jobs
答案
C
解析
这是一道推断题。本题询问“文章中划线句子说明了什么?”。文章中划线句子有一个转折连词“however”,这表明划线部分将与前面内容形成对比。上句话中谈到You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. (知道如何去调查信息和挖掘信息对每一个人都很重要),这里所谈到的每一个人既包括普通人也包括科学家。而划线句子进一步谈到对于科学家而言则需更进一步。显而易见这是在将科学家和普通人做对比,说明他们之间的不同,因此正确答案应该选择C。
