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 file 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.
“...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

A sound scientific theory should be one that________.

A.works under one set of conditions at one time and also works under the same conditions at other times
B.leaves no room for improvement
C.does not allow any change even under different conditions
D.can be used for many purposes

What is the main idea of the passage?

A.Scientists are different from the ordinary people.
B.The theory of relativity.
C.Exactness is the secret of science.
D.Exactness and way of using tools is the key to the making of a scientist.

Robert Frost was one of America’s best known and most honored serious writers. But his fame came late in his life.
He was born in San Francisco, California in 1874. He lived in California during his early childhood. He was named after the chief Southern general in America’s Civil War. The general’s name was Robert Edward Lee. The poet was named Robert Lee Frost, because his father wanted to honor the general.
Someone once asked another American writer, Ernest Hemingway, how to become a writer. The best thing, he said, was to have an unhappy childhood. If this is true, Robert Frost’s childhood was unhappy enough to make him a very good writer. Robert Frost’s father was a reporter who wanted to be a politician. He often drank too much wine and became angry. Robert was the victim (受害者) of his anger.
Robert Frost finished high school in 1891. After high school, Robert’s grandfather offered to pay his costs at Dartmouth College. But Robert left the school after a few months. He did not like it. He spent the next few years working at different jobs. At one time, he worked in a factory. Later, he repaired shoes. He was a teacher. He was a reporter. Always, he wrote poetry.
Robert Frost attended Harvard University for two years. After that, he returned to the many jobs he held before. For a while, Frost tried to take care of a farm in the state of New Hampshire. He was not a successful farmer. And he continued to write poetry. He said that until 1930, he earned only about ten dollars a year from writing.
In 1912, he decided to try to make a new start. He took his family to Britain. The cost of living was low. In Britain, Frost found a publisher for his first book of poems. The book was called A Boy’s Will. When it appeared in 1913. Frost received high praise from British readers. Praise was something he had not received in his own country.
Ezra Pound, another American poet living in Britain, read the poems and liked them very much. He wrote a magazine article about Frost. He also helped get Frost’s second book of poems published in America. That book was called North of Boston.

A friend is better than fortune. A friend is worse than poison in some cases.
The two sentences above have opposite meanings and seem to be unreasonable, but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us into bad ways.
  My ideal friend is of course a good friend whose goodness is shown below — he has no bad habits, such as smoking and drinking. He lives in frugality (节俭). He studies hard so as not to waste his golden time. At home he honors his parents and loves his brothers; at school he respects his teachers and shares the feelings of his classmates. He treats those truly who are true to him. In a word, he has all the good characteristics that I don’t have. I can follow him as a model. With his help I can be free from all difficulties.
Indeed, if I have such a person as my friend, I shall never fear difficulty and I shall never know the existence of the word “failure”.

A.how to make friends with others

Nowadays, the increase in the prices of agricultural products is one of the greatest concerns of the people and the government. The government has announced a series of policies(政策) to prevent the prices from rising further. Rising housing prices is still a big concern for the people, but since farm products are needed every day, the increase in their prices has made life very difficult for them.
Many people may think the increase will help farmers. But have higher prices of farm products really benefited the farmers?
Take the increase in vegetable prices in the first half of this year for example. Though natural disasters such as droughts and spring frost did not cause the prices of farm products to increase greatly—in fact, prices of some products did not increase at all—vegetables have become dearer by as much as 20 percent compared to that of last year. This means only a small part (or even none) of the extra money that city people have paid to buy farm products has gone to the farmers. The extra cost actually has gone to middlemen.
As the fact shows, just increasing prices of farm products will have negative influence on the entire economy. On one hand, the price increase has created some abnormal phenomena, which hurts farmers’ interests. On the other hand, resources will enter the agriculture because of the high price of farm products, which would finally create negative effect on the whole economy.
In such a case, it would be better to leave the market to decide the prices instead of raising farm products’ prices to protect the interests of farmers. Actually, such a way will be better for farmers in the long run.
What does the author mainly want to tell us by writing the passage?

A.Farmers benefit a lot from the price increase.
B.Price increase has not helped farmers.
C.We should be sorry for farmers.
D.Price increase has a bad effect on economy.

Many people think the increase in the prices of farm products benefits ______ .

A. nobody B.the country C.middlemen D.farmers

The following statements are true EXCEPT ______ .

B.it is better for farmers to leave the market to decide the prices in the long run
C.natural disasters did not cause the prices of farm products to increase greatly
D.rising housing prices has made life very difficult for people

A.Negative. B.Indifferent.(漠不关心的)
C.Enthusiastic. D.Positive.

Parents have widely different views on the problem of pocket money. Four new fathers were asked this question and this is how they answered.
Ashish Khanna: Although many argue that pocket money helps develop children’s sense of value, I don’t agree. I wouldn’t give my child any pocket money. First of all, I never got pocket money and I seem to have a good value for money. If my child ever needed something and I felt it was a reasonable (合理的) request, I would buy it for him.
Sharad Sanghi: No, I wouldn’t give my child pocket money because I don’t want to create the perception (观念) of “her” money and “my” money. Besides, if I refuse to buy her something that I think is bad for her, she may buy it with her pocket money on the sly. In this way, I would lose control over my child’s requests. I feel it also encourages children to care more about money than anything else. I don’t want my child to start judging other children by the amount of money or pocket money they have.
Rakesh Shah: Yes, I would give my child pocket money because I feel that children should learn to spend money properly. I will give him a fixed amount every month and if he spends the money before the month is over, he will learn a lesson and not spend money so freely. He will learn what his limitations (限制) are and feel the difficulty when he has to pay for something that is over his own pocket.
Rajiv Patel: Yes, I would give my child pocket money because it is important that he learns to manage money. But I would not give it to him on a weekly or monthly basis. He would have to earn it. If he helped me finish some of my jobs or helped his mother with housework, I would reward him. This helps him realize that “money does not grow on trees” and it requires hard work to earn money.
Ashish Khanna may agree that _____.

A.he was given too much pocket money when young
B.he can take much control of his child by money
C.he will buy anything he thinks his child really needs
D.pocket money helps children develop a good value for money

The underlined phrase “on the sly” in Paragraph 3 is the closest in meaning to “_____”.

A.for free B.at a lower price
C.happily D.secretly

Who would give his child pocket money every month?

A.Ashish Khanna. B.Sharad Sanghi.
C.Rakesh Shah. D.Rajiv Patel.

What do Rakesh Shah and Rajiv Patel have in common?

A.They want their children to learn to manage money from an early age.
B.They ask their children to get pocket money by working.
C.They teach their children the difficulty of making money.
D.They allow their children to spend money freely.

People often use gestures to express our feelings, but the problem is that the gestures can be understood in different ways.
It is true that a smile means the same thing in any language. So does laughter or crying. Fear is another emotion(情感) that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like “he went pale and began to tremble” suggests that the man is either very afraid or he has just got a very big shock.
However, “he opened his eyes wide” is used to suggest anger in Chinese whereas in English it means surprise. In Chinese, surprise can be described in a phrase like “they stretched out their tongues!” “Stretching out your tongue” in English is an insulting(侮辱的, 无礼的)gesture or expresses strong dislike.
Even in the same culture, people differ in their ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people’s faces. Other studies show that older people usually find it easier to understand body language than younger people do.
Which of the following is TRUE according to the text?

A.We can easily understand what people’s gestures mean.
B.It is difficult to tell what people’s gestures really mean sometimes.
C.Gestures can be understood by most people but words are not.
D.Words can be better understood by older people.

People’s facial expressions may be misunderstood in different cultures because ______ .

A.people from different cultures have different meanings about some facial expressions
B.people speaking different languages have different facial expressions

From the passage, we can conclude(得出结论) that ______ .

A.words are often more difficult to understand than gestures
B.gestures can be more effectively used than words to express feelings
C.gestures can be used to express feelings
D.gestures are used as frequently as words to express feelings

The best title for this passage can be ______ .

A.Gestures B.Feelings
