Passage Two
What makes a person a scientist? Does he have ways or tools of learning that are different from tho of others? The answer is no. It is not the tools a scientist us but how he us the tools that makes him a scientist.(第6题) You will probably agree that knowing how to u a power saw（power saw，动力锯，I saw a saw sawing a saw.） is important to 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 f
urther; （第7题答案）he must be sure that he was a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large t of ideas about how the world works.（第8题）
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 t of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist obrves 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 his mathematics was later tested through investigation. （第ayer9题arrive at得出；test测试，题目中的build up是指确定。）Einstein's ideas were shown to be correct. A scientist us many tools for measurement. Then the measurements are ud to make mathematical calculations that may test his investigations.
