问题 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 1、What makes a scientist according to the passage?
A. The tools he uses
B. The way he uses his tools
C. His way of learning
D. The various tools he uses
答案B
解析这是一道细节题。本题询问“文章认为如何成为一名科学家？”。本题的问题其实是文章第一句话的另一种表述，因此找到文章第一句话的答案，即找到了本题的答案。文章中第一话设问完后，紧接着就给出了答案，“It is not the tools a scientist uses but how he uses these tools that makes him a scientist.”，这句话表明如何使用工具是成为科学家的关键，因此本题的答案应该是选项B，即“他使用工具的方式”。
