二、阅读理解

1、Laws have been written to govern the use of American National Flag, and to ensure proper respect for the flag. Custom has also governed the common practice in regard to its use. All the armed services have precise regulations on how to display the national flag. This may vary somewhat from the general rules. The national flag should be raised and lowered by hand. Do not raise the flag while it is folded. Unfold the flag first, and then hoist it quickly to the top of the flagpole. Lower it slowly and with dignity. Place no objects on or over the flag. Do not use the flag as part of a costume or athletic uniform. Do not print it upon cushions, handkerchiefs, paper napkins or boxes. A federal law provides that the trademark cannot be registered if it comprises the flag, or badgers of the US. When the flag is used to unveil a statue or monument, it shouldn't serve as a covering of the object to be unveiled. If it is displayed on such occasions, do not allow the flag to fall to the ground, but let it be

carried high up in the air to form a feature of the ceremony. Take every precaution to prevent the flag from soiled. It should not be allowed to touch the ground or floor, nor to brush against objects.

2、 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 makes 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 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 answers 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 his 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.

A：The tools he uses.

B：The way he uses his tools.

答案： A

(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 investigations are important in science

D：that the mathematical calculations may test his investigations

答案： C

(5)、What is the main idea of the passage? ________
