During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does.
In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one’s brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.

Recently, a student used his Personal Digital Assistant (PDA) to film a female teacher scolding and tearing the work of a classmate. The public discussion that the incident caused started on the Internet. However, when it came to the media’s attention, it quickly became a major topic in the education circles. The reactions so far suggest that the focus of the debate has been on one question: whom to blame?
Teachers who are anxious to defend their professional dignity have tried to put the blame on the students. They mentioned their right to privacy 隱私）and for this reason they requested the Ministry of Education (MOE) to prohibit PDAs in schools. On the other hand, some parents and students have taken a different position. They feel that the teacher is also at fault. Caught up in the war of words between both sides, people are no longer interested in the “truth” of the matter which seems now unimportant. It was left to newspapers to discover the central point of the controversial issue, by stressing the problems that are not always easily noticed in our educational system.
For those responsible for educating the young, this PDA incident conveys the message that “Times have changed”，a reality that must have been felt even more strongly by the female teacher when reflecting on this unpleasant experience. Different times call for different professional approaches in education. The ability to understand the students they are teaching has always been the quality of successful teachers. Despite some factors, the incident shows that the teacher lacks good qualities on her part. Besides, the rules under current system to deal with recalcitrant students need to be improved. Also, it is an example which shows the issue we are familiar with: what to do with new technology? With PDA, the new technology, the interaction (交流）between the teacher and students in classroom has been changed.
小題1:The author’s purpose in writing this passage is to______.
A．improve the teachers’ way of teaching
B．stress the using of PDA in the classroom
C．change the students’ behavior in the classroom
D．discuss the potential problems of educational system
小題2:The underlined word “recalcitrant” in paragraph 3 probably means______?
A．difficult to controlB．interested in nothing
C．unwilling to learnD．ready to obey rules
小題3:The writer’s attitude toward the PDA incident is______.
A．optimisticB．critical
C．uncertainD．a(chǎn)pproval
小題4:What might be the best title for the passage?
A．Whom to blame?
B．The PDA incident
C．Times have changed
D．What to do with new technology?

A child, who has once got interested in a tale, likes, as a rule, to have it retold in almost the same words, but this should not lead parents to treat printed fairy stories as formal texts. It is always much better to “tell” a story than just “read” it out of a book, and, if a parent can produce his own as an improvement on the printed text, according to his child’s actual situation, so much the better.
There is a charge made against some fairy tales, as they probably harm children by frightening them or leaving them sad feelings. To prove it, an experiment has been done to show that children who have heard terrible fairy stories often feel more uneasy than those who have not. As for fears, there are some cases where children get timid (膽怯的) by some fairy story. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition may weaken the pain of fear.
There are also people who object to fairy stories on the grounds that the stories are not objectively true, and that those giants, witches, two-headed dragons, magic carpets etc. do not really exist, so children should be taught to learn the reality by studying history, instead of being got fond of the strange side in fairy tales. Those, who prefer to create such stories, are so peculiar (奇怪的) that it is hard to argue with them. If their creative exaggeration (夸張) were sound, the world should be full of mad men attempting to fly from New York to Philadelphia on a stick or covering a telephone with kisses in the belief that it was their beloved girl-friend.
Not once is a fairy story ever declared to be a description of the real world, but not every child is clever enough to be aware of it. Parents should choose their children’s “bed-time” reading materials with much care. Only the fairy stories containing positive effect will make a clever and caring child with rich imagination.   
小題1:The author considers that a fairy story is more effective when it is ______.
A．repeated without any change
B．treated as no more than a joke
C．made some changes by parents
D．set in the present situation
小題2:According to the passage, when a child hears a terrible fairy story, ______.
A．he will get more interested
B．great fear can take place in him
C．he will like it to be repeated
D．a(chǎn)n experiment is being done
小題3:The word “sound” in Para.3 can be understood as ______.
A．fashionable B．forgettableC．a(chǎn)vailableD．believable
小題4:The author mentions “sticks” and “telephones” to prove that ______.
A．fairy stories are all made up
B．fairy tales lead to misunderstanding
C．children are cheated by old stories
D．there is more concern for children
小題5:One of the reasons why some people are not in favor of fairy tales is that ______.
A．they are made up far from the truth
B．they are so full of imagination
C．they are not interesting at all
D．they make history difficult to teach
小題6:It makes sense that parents choose fairy stories with ______ as “bed-time” reading materials..
A．formal printingsB．creative scenesC．positive effectD．terrible characters

Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed.
The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks.
Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models.
The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach.
“ We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships,” he said. “ To me, archeology is like search and rescue, but everyone has been dead for 5,000 years.”
The doctors are very excited about the potential for surgical robots to do things that humans can’t do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves.
小題1:What can we learn from the first paragraph?
A．The doctors carry out surgery using snake robots mainly for heart disease.
B．The doctors are very satisfied with the new snake robots during surgery.
C．Snake robots are completely free of human control today.
D．Other supplementary appliances will be added to snake robots.
小題2:Which of the following is true, according to the passage?
A．Snake robots are only used in the medical field.
B．Snake robots can reduce the patients’ medical costs.
C．Scientists are uncertain about the prospects for snake robots.
D．Scientists are forced to spend a lot of time researching snake robots.
小題3:How can snake robots work best, according to the passage?
A．When they carry tiny cameras, scissors and forceps.
B．When they are operated by experienced doctors.
C．When they are given a wireless function.
D．When they are designed for particular tasks.
小題4:Why do we know about Howie Choset, according to the passage?
A．He thought snake robots of different sizes can be used for different types of surgery.
B．He thought patients’ pain had been slightly reduced with the help of snake robots.
C．He also made snake robots for search, rescue and exploration.
D．He is very interested in researching ancient Egyptian ships.
小題5:The writers attitude towards the new technology is ______.
A．optimisticB．doubtful C．objective D．negative

To learn an instrument(樂器) such as the violin or accordion（手風琴）takes years. The job opportunities for musicians are scarce and competition is fierce. Then why are more people than ever before paying a lot of good cash to get their children the best music teaching they can afford?
The secret lies in the influence of music on the whole person. It has been found that learning a musical instrument actually increases a person’s IQ over time. Different instruments and different trypes of music have varying effect, with classical music and the string（弦樂） family coming out on top, potentially increasing you IQ by up to 12 points!
When is a good time to start learning music? Experts have found that even the fetus（胎兒）can benefit from listening to classical music. Surround yourself and your family with good music from the first. The Suzuki Piano Method teaches children from the age of 3 years piano, with two lessons per week. From preschool, children can learn to read music and play from sheet music. Progress in learning your instrument is directly proportional（成比例的）to the amount of practicing.
Is there such a thing as an unmusical child? Shinichi Suzuki proposes that music is the native home language of all human beings and therefore nobody can be “unmusical”. Of course there are exceptional talents, compared to which others may seem to be slower learners.
Is there any benefit for adults in starting an instrument? Apart from the purely relaxing aspect, yes. Learning an instrument can earn even adults additional IQ points, and as an added benefit in improves your health by reducing your stress levels. Your social life may benefit too, if you are prepared to come out of your box and join occasions such as Ceilidhs (musical get-togethers) or arrange house concerts. It has been established that people who play instruments tend to be more emotionally balanced and more patient with themselves, others and life in general.
So go ahead, sign up for that amateur orchestra, dust off your old trombone（長號）or take your first real six-string down from the attic（閣樓）; get out there and play!
小題1:Playing which of the following musical instruments can help increase a person’s IQ most?
A．The pianoB．The violinC．The tromboneD．The accordion
小題2:According to Shinichi Suzuki,             .
A．The progress in learning an instrument depends on natural gifts
B．It is too late for an adult to start an instrument

Living in a modern society with more and more out-of-date but still useful computers, many people have to face such a troubling problem: How to deal with those old computers? Some old ones are put away in homes. Many more are just thrown out with the rubbish.
Don’t worry! Some companies are coming up with new ways to cut the number of old computers. Sony, Dell, Hewlett-Packard and other companies now agree to take back some old computers.
In some countries, there are laws about what to do with old computers. By law, computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升級）.
While many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（組織）are working to solve this problem. They collect and repair old computers before sending them to schools, charities（慈善團體）and people who need them. In this way, we can turn one person's rubbish into someone else's useful things-and cut down on waste.
小題1:What do many people do with old computers?
A．They sell them to others.
B．They try to repair them.

Here in Alaska, the wolf almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, laws were passed to protect the wolves from sportsmen and people who catch the animals for their fur. So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally lives on animals in the deer family. People there also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the plant life there. When the deer can’t find enough food, they die.
If the wolves continue to kill large numbers of deer, the deer will disappear some day. And the wolves will, too. So we must change the life cycles there. If we killed more wolves, we would save them from starving. We also save deer and some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the United States government to send a team of scientists to study the problem. They believe it is necessary to kill wolves in some areas and to protect them in places where there is a small population.
小題1:In Alaska, laws have been passed to ____.
A．protect people from wolves and deer
B．protect wolves from becoming dangerous
C．protect wolves from dying out

小題2:Why is it that if wolves go on killing a good many deer the wolves will die out?
A．Because wolves will have no deer to kill.
B．Because people will kill them for punishment.
C．Because killing deer is dangerous.
D．Because wolves mainly live on deer.
小題3:In order to protect more deer from being killed, one way is to ____.
A．pass a lawB．keep deer away from wolves
C．kill more wolvesD．serve wolves more food

The common cold is the world's most widespread illness, which is a serious infection that man receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by touching directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in separate Arctic (北極的)areas, explorers have reported being free from colds until touching again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the trenches, cold and wet, seldom caught colds.
In the Second World War, prisoners at Auschwitz concentration camp, bare and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for a long time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to reduce the symptoms.
小題1:The writer thinks the cause of catching cold is due to_______.
A．touching anyone directly
B．touching anyone indirectly
C．cold weather
D．getting viruses from person to person
小題2:Arctic explorers may catch colds when___.
A．they are working in the separate Arctic areas
B．they are writing reports in terribly cold weather
C．they are free from work in the isolated Arctic regions
D．they are coming into touch again with the outside world
小題3:Volunteers taking part in the experiments in the Common Cold Research Unit___.
A．suffered a lotB．never caught colds
C．often caught coldsD．became very strong
小題4:The passage mainly discusses___.
A．the experiments on the common cold
B．the mistake about the common cold
C．the reason and the way people catch colds
D．the continued spread of common colds
