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 isn’t the tools a scientist uses but how he uses these tools which 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 investigation, 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 he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s 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 tim
e must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(实证) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正确性) of his mathematics was later tested through investigation. Einstein’s
ideas were proved to be correct. A scientist uses
many to
ols for measurements. Then the measurements are used to make mathematical calculations(计算) that may test his investigations What makes a scientist according to the passage?

| B．doesn’t allow any change even under different conditions |
| C．Can be used many times under different conditions |

I travel a lot, and I find out different "styles" of directions every time I ask "How can I get to the post office?"
Foreign tourists are often confused in Japan because most streets there don't have names; in Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."
In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."
People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's about five minutes from here." You say, "Yes, but how many miles away is it?" They don't know.
It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!When a tourist asks the Japanese the way to a certain place they usually________.
| A．refer to recognizable buildings and places |
| B．show him a map of the place |
| C．tell him the names of the streets |
| D．describe the place carefully |
What is the place where people measure distance in time?
| A．New York. | B．Kansas. |
| C．Los Angeles. | D．Iowa. |
People in Yucatan may give a tourist a wrong answer ________.
| A．so as to be polite | B．as a test |
| C．in order to save time | D．for fun |

| A．It's useful for travelers to know how to ask the way properly. |
| B．It's important for travelers to understand cultural differences. |
| C．People have similar understandings of politeness. |
| D．New Yorkers are generally friendly to visitors. |
