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 a tool 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 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 question 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 change the scientist observes in a demonstration must be explained by the change 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. Einstein's ideas are 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.
1."...knowing how to investigate, how to discover information, is important to everyone. " The author says this to show________.
A. the importance of information
B. the difference between carpenters and ordinary people
C. the difference between scientists and ordinary people
D. the importance of thinking
2.A sound scientific theory should be one that________.
A. works under one set of conditions at any time
B. leaves no room for improvement
C. does not allow any change even under different conditions
D. can be used for many purposes
3.Which of the following statements is NOT tree?

B. Tools which a scientist uses for measurements are used to make mathematical calculations that may test his investigations.
C. A scientist should know more about other branches of knowledge to arrive in his achievement.

高二英语阅读理解中等难度题查看答案及解析
Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is impelled(推进，敦促) by some unseen force to do the same thing repeatedly; thus a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation (形成) of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits as long as they live, and sometimes become ruined by them..
There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and thoroughness(周详).
Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons form habits which ought to have been avoided.
We ought to keep from all these old habits, and try to form such habits as will prove good for ourselves and others.

When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the guarantee, or any other records that might help, at the store of buying. In most cases, his action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction.
A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer’s favor, taking it as true that he or she has a just right.
Consumers should complain in person whenever possible, but if they can’t get to the place of purchase, it is acceptable to phone or write the complaint in a letter.
Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this can’t be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo does not work”.
The store manager may advice the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumer’s rights.
1.When a consumer finds that he or she bought has a fault in it, he or she should do first ________.
A. complain personally to the manager in a loud way
B. show something provable in written form to the store
C. threaten to take the matter to court
D. write a firm letter of complaint to the store
2.If a consumer wants a quick settlement of his problem, it’s better to complain to ________.
A. a shop assistant B. the producer
C. a public organization D. the store manager
3.The most effective complaint about what was bought can be made by ________.
A. showing the fault of it Lo the producer
B. saying firmly it is of poor quality
C. explaining exactly what is wrong with it
D. asking politely to change it
4.The passage tells us ________.
A. how to make the complaint have a better effect
B. how to settle a consumer’s complaint
C. how to avoid buying something wrong
D. how to deal with complaints from consumers
