Even after centuries of 【小题1】(science) research, no one knows for sure why human beings laugh.
Charles Darwin guessed that laughter, 【小题2】 begins in infants as young as three months old, served as a"reward"to parental care-giving. Laughter of infants sounded and felt so different from crying, and he believed that even prehistoric(史前的) parents must have regarded it 【小题3】 a sign of well-being. The parents enjoyed the laughter, which encouraged them 【小题4】(continue) caring for the child.
One of the most interesting things researchers have learned is the powerful healing effect of laughter. Well,actually they're re-learning it after centuries of neglect:in the Middle Ages, doctors "treated" their 【小题5】(patient) by telling them jokes.
Scientists 【小题6】(learn) a lot about laughter so far.You use 15 different muscles in your face to laugh. The sound of laughter is created when you breathe in deeply 【小题7】 then breathe out the air. The typical laugh is made up of pulses(节奏)of sound that are about 1/15th of a second long and 1/5th of a second apart.When tape-recorded and 【小题8】(play) backward,laughing sounds 【小题9】(virtual) the same as it does when it is played forward. 【小题10】 was also found that the most laughter took place when males were talking and females were listening, and the least took place when females were talking and males were listening.

   It is a familiar scene these days: employees taking newly laid-off co-workers out for a drink for comfort. But which side deserves more sympathy,the jobless or the still employed?On March 6,researchers at a conference at the University of Cambridge suggested it was the latter.

Brendan Burchell,a Cambridge sociologist,presented his analysis based on various surveys conducted across Europe. The data suggest that employed people who feel insecure in their jobs show similar levels of anxiety and depression as those who are unemployed. Although a newly jobless person's mental health may“bottom out”after about six months,and then may even begin to improve,the mental state of people who are continuously worried about losing their own job“just continues to get worse and worse”, Burchell says.

Psychologists support this theory by arguing that human beings feel more stressed during times of insecurity because they sense an immediate but invisible threat. Patients have been known to experience higher levels of anxiety, for example, while waiting for examination results than knowing what they are suffering from—even if the results are cancer. It's better to get the bad news and start doing something about it rather than wait with anxiety.  When the uncertainty continues, people stay in a nonstop“fight or flight”response, which leads to damaging stress.

But not every employee in insecure industries has such a discouraging view, Burchell says. In general, women get on better. While reporting higher levels of anxiety than men when directly questioned, women score lower in stress on the 12-item General Health Questionnaire, even when they have a job they feel insecure about losing.  As Burchell explains,“For women, most studies show that any job—it doesn't matter whether it is secure or insecure—gives psychological improvement over unemployment.”He supposes that the difference in men is that they tend to feel pressure not only to be employed, but also to be the primary breadwinners, and that more of a man's self-worth depends on his job.

【小题1】Why do researchers think the still employed deserve more sympathy?
A.They have to do more work since then.
B.They have no chance to find better jobs.
C.They have to work with inexperienced workers.
D.They constantly worry about losing their jobs.
【小题2】What is most likely to cause a“fight or flight”response?
A.Not having a paid job.
B.Poor job conditions.
C.Not knowing what will happen.
D.Pressure to work longer hours.
【小题3】What will the writer talk about following the last paragraph?
A.Advice on preparing for a job interview.
B.Advice on handling pressure from insecure industries.
C.Some knowledge of psychology.
D.Difference in men and women.
【小题4】What is the main idea of the passage?
A.Is it less stressful to get laid off than staying on?
B.Should more sympathy be given to the jobless?
C.Do employees bear more stress than ever before?
D.Do men or women show higher levels of anxiety?

Satellites(卫星) are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometers above the equator(赤道).Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae(天线)facing the earth.Sometimes, it moves away from its orbit(轨道),So there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10-12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired.Often,very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash(撞)into each other.
【小题1】Which of the following is NOT done by satellites according to the passage?
A.Sending information for weather forecast.
B.Taking photographs of the Earth.
C.Sending TV pictures.
D.Providing food for airplane pilots.
【小题2】What’s the speed the earth rotates at?
A.35,880 kilometers per hour.
B.335,880 kilometers per hour.
C.11,000 kilometers per hour.
D.110,000 kilometers per hour
【小题3】Why does the satellite move around the world at the same speed as the Earth rotates?
A.In order to take photographs.
B.In order to stay in a certain position in the orbit.
C.In order to move away from its orbit.
D.In order to send television pictures.
【小题4】What does the underlined word “This” in the 3rd paragraph refer to?
A.A satellite.
B.A little rocket.
C.A satellite seems to stay in the same place in the sky.
D.The satellite puts the rockets in the right position.

EQ is a way of 【小题1】(measure) how a person recognizes emotions in himself or herself and others , and makes these emotional states work better as a group or team. IQ is a value that 【小题2】(indicate) a person's ability to learn, understand, and apply information and skills in a meaningful way. The major 【小题3】(differ)between EQ and IQ is what part of a person's mental abilities they measure; understanding emotions or understanding information.

According to some 【小题4】(theory)of brain function, a high EQ means someone is self-confident ,self-aware, and able to handle difficult emotional experiences. It is often tied directly 【小题5】 the degree of success a person may have in the workplace and in 【小题6】(person)relationships. People with high EQs can often better recognize and control their own emotions, and recognize  emotional states of others 【小题7】(adjust)their behavior accordingly.

A person's IQ, on the other hand, measures concepts like logical reasoning and math skills rather than creative potential or emotional abilities. People with high IQs may be able to learn certain subjects very quickly and make connections between ideas 【小题8】 will be missed by others. They often have great academic success, 【小题9】 they may struggle to find classes that challenge them. The ability to acquire knowledge does not 【小题10】(necessary)mean people can recognize and manage their own emotional states , however.

   About ten men in every hundred suffer from color-blindness in some way. Women are luckier: only about one in two hundred is affected on this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color-blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green — a strange world indeed.

Color-blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in bright light and to tell the difference between colors. There are also millions of "rods", but these are used for seeing when it is near dark. They show us shapes but no color.

Some insects have favorite colors. Mosquitoes(蚊子) prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky.

With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

【小题1】What is the passage mainly about?
A.Colors and their surprising effects.
B.Women being luckier than men.
C.Danger caused by color-blindness.
D.Color-blindness.
【小题2】What can we know about the color-blind?
A.Not all of them have the same problem in recognizing colors.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.
【小题3】According to the passage, with the help of the cones, we can ______.
A.tell different shapes
B.see in weak light
C.kill mosquitoes
D.tell orange from yellow
【小题4】Which can we use to attract and kill mosquitoes?
A.Red light.
B.Yellow light.
C.Blue light.
D.Green light.

   "Creativity is the key to a brighter future, "say education and business experts. Here is how schools and parents can encourage this important skill in children.

If Dick Drew had listened to his boss in 1925, we might not have the product that we now think of as great importance: a new type of tape. Drew worked for the Minnesota Mining and Manufacturing Company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Drew improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their working time just thinking about and developing new ideas.

Creativity is not something one is just born with, nor is it necessarily a character of high intelligence. The fact that a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something.

Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can gain information but can't recognize ways to use it in new situations. They may know the rules correctly but they are unable to use them to work out practical problems.

It is important to give children choices. From the earliest age, children should be allowed to make decisions and understand their results. Even if it' choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should try to let them decide how to use their time or spend their money. This is because the most important character of creative people is a very strong desire to find a way out of trouble.

【小题1】What did the company where Drew once worked learn from its mistake?
A.It should encourage people to work a longer time.
B.People should be discouraged to think freely.
C.People will do better if they spend most of their working time developing new ideas.
D.It is necessary for people to spend some of their working time considering and developing new ideas.
【小题2】We can know from the passage that creativity _________.
A.something that most people are born with
B.something that has nothing to do with intelligence at all
C.a way of using what one has learned to work out new problems
D.something that is not important to the life in the future at all
【小题3】Why don't schools try to encourage creativity?
A.They don't attach importance to creativity education.
B.They don't want their students to make mistakes.
C.They pay no attention to examination marks.
D.They think it impossible to develop creativity in class.
【小题4】What should the parents do when their children decide how to spend their money?
A.Allow them to have a try.
B.Try to help them as much as possible.
C.Take no notice of whatever they do.
D.Order them to spend the least money.
