“The reason behind the remarkable achievement is China's long tradition of caring for children both at home and in society," he said.

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(調(diào)查),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 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.
小題1:What makes a scientist according to the passage?
A.The tools he uses.B.His ways of learning.
C.The way he uses his tools.D.The various tools he use
小題2:“The scientist, however, goes one step further,” the author says this to show      。
A.the importance of information
B.the importance of thinking
C.the difference between scientists and ordinary people
D.the difference between carpenters and people with other jobs.
小題3:A sound scientific theory should be one that      .
A.does not only work under one set of conditions at one time, but 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
小題4:What is the main idea of the passage?
A.Scientists are different from ordinary people.
B.The theory of relativity.
C.Exactness is the core(核心)of science.
D.Exactness and way of using tools are the keys to the making of a scientist.

In this modern world, we rush around all day, doing things, talking, sending and reading message. We are always on, always connected, always thinking, always talking. There is no   36   for stillness.

April 22,2010 will be the 18th celebration of the annual Take Our Daugluers to Work Day (TOD), a project the National Ms.Foundation for Women of America (NFW) developed to expose girls to expanding opportunities for women in the workplace.
The program offers, millions of girls a first - hand view of the many career opportunities available in their futures.Now that women make up 46 peroent of the U.S.workforce, girls can find role models in every occupational field-from politics to molecular biology to professional athletics, to name just a few.TOD encourages girls to focus on their abilities and opportunities, not just their appearance.

Perhaps because the program had become so widespread and successful, TOD had been criticized for excluding boys.a(chǎn)nd it was expanded in 2003to include boys.The program’s official website states that the program was changed in order to provide both boys and girls with opportunities to explore careers at an age when they are more flexible in tenns of gender stereotyped roles."We should also show boys that becoming a child care provider is as acceptable a choice as becoming a police officer or CEO," added Sara K.Gould.executive director of the NFW.

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase(抹去) the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatryat Harvard Medical School. : “This could relieve a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity(特質(zhì)). They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist
53.The passage is mainly about            .
A.a(chǎn) new medical invention
B.a(chǎn) new research on the pill
C.a(chǎn) way of erasing painful memories
D.a(chǎn)n argument about the research on the pill
54.The drug tested on people can            .
A.cause the brain to fix memories     
B.stop people remembering bad experiences
C.prevent body producing certain chemicals
D.wipe out t he emotional effects of memories
55.We can infer from the passage that                  .
A.people doubt t he effects of the pills
B.the pill will stop people’s bad experiences
C.taking the pill will do harm to people’s health
D.the pill has probably been produced in America
56.Which of the following does Rebecca Dresser agree with?
A.Some memories can ruin people’s lives.
B.People want to get rid of bad memories.
C.Experiencing bad events  makes us different from others.  
D.The pill will reduce people’s sufferings from bad memories.

Everybody knows that words can carry messages. People communicate with words. Books, magazines, TV , radio and films all help us to know what is going on in the world and what people are thinking about.
Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you put up your hand in class, the teacher knows that you say something or ask a question. You shake your head, and people know you are saying “No”. You nod and people know you are saying “Yes”.
Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on doors tell you where to go in or out. Have you ever noticed there are a lot of signs around you and you receive messages from them all the time?

In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence--- as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch(關鍵時刻), we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instinct remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learned that violence never solves a problem but makes it even acute. The sheer horror, the bloodshed(流血), the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.
The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persuaded by their own kind because they advocate such apparently outrageous things as law enforcement(執(zhí)行). If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.
72. What is the best title for this passage?
A. Advocating Violence.            
B. Violence Can Do Nothing to Diminish Race Prejudice
C. Violence as a Legitimate Solution  
D. Violence: The Instinct of Human Race
73. Recorded history has taught us __________.
A. violence never solves anything   B. nothing
C. the bloodshed means nothing     D. everything
74. It can be inferred that truly reasonable men ________.
A. can’t get a hearing   B. are looked down upon 
C. are persecuted      D. have difficulty in advocating law enforcement
75. According to the author, the best way to solve race prejudice is ________.
A. law enforcement   B. knowledge  C. nonviolence   D. mopping up the violent mess
