Before the early 1960’s people interested in the differing roles of the left and right hemispheres(半球) of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the “dichotic listening” procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented(回憶) in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear.
In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory(聽覺的) signal: music. When right-handed people listen to melodic patterns they report them better from the left ear.

SOUTHPORT, ENGLAND—A British teaching union famous for strange ideas has supported a plan to employ dogs as classroom assistants.
At the yearly conference of the Professional Association of Teachers in Southport, northwest England, one person suggested properly trained dogs be able to keep order in primary schools. They can round up lost children and protect those who experience unfortunate “accidents”. Wendy Dyble, a Sheetland Islands woman who teaches children up to age seven, made it clear to her fellow friends that she was not “barking mad”. They obviously believed her, supporting her idea by 16 votes to 13, with a total of 63 abstentions（棄權）.
She said big dogs could help round up children, keep them in line, lick up the milk they spill on the floor and provide the extra eyes that a teacher needs to keep order. “A big dog would also be helpful for stopping flights and look for lost property, like gym shoes or dolls,” Dyble said at the conference. “The dog will also be useful in sniffing out(find out) smells that children do not own up to,” she added. “It would be nice for the teacher not to have to go round sniffing each child to find the criminal.”
The idea was welcomed by the Dog Defense League but less by bigger teaching unions. A spokesman for Education Secretary, David Blunkett, who is blind, said his guide dog was always popular with pupils when he visited schools. The Professional Association of Teachers, with around 35,000 members, is the smallest teaching union in Britain. It has an honor for occasional strange ideas.
Earlier this week, its yearly conference here suggested stopping exams because they lead to stress and introducing selection at the age of 12 based on physical coordination（調整）and manual（手工的）skill.
小題1:According to the writer’s opinion, to employ dogs as classroom assistants ________.
A．is not a good idea
B．can improve the relation between children and animals
C．is beyond ordinary people’s imagination
D．can make some teachers lose jobs
小題2:What Dyble said at the conference ________.
A．gained some support from the members
B．frightened everyone present
C．interested everyone present
D．caused some trouble to trained dogs
小題3:The last paragraph of this passage ________.
A．has nothing to do with the topic of this passage
B．shows there are too many exams in British school
C．provides further facts about the teaching union
D．shows the writer’s anger to the union

The twentieth century saw greater changes than any century before: changes for the better,
changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology m the application of science m has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science -- a wider and deeper knowledge in all fields of learning; in applied science -- a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind.  The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said, “The web of our life is of a mingled yarn (紗線), good and ill together.” The above brief review of the application of only one part of human activities----- science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?
小題1:Which of the following best shows the structure of the passage?
A．B．C．D．
小題2:From the fourth paragraph, we can infer that________.
A．a great many nuclear weapons were actually used for war
B．a large number of nuclear weapons should have been used for war
C．the author is doubtful about the ruin of human beings by nuclear weapons
D．the author is anxious about the huge number of nuclear weapons on the earth
小題3:The underlined word "mingled" in the last paragraph most probably means________.
A．simpleB．mixedC．sadD．happy
小題4:What do you think the author is most likely to suggest if he continues to write?
A．Further application of science to war.
B．More reading of William Shakespeare.
C．Proper use of science in the new century.
D．Effective ways to separate the good from the ill.

Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a ＄10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak” with their teachers, their classmates, and their families. however, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”
小題1:The main purpose of the laptop program is to give each student a laptop to _______.
A．use for their schoolworkB．access the Internet

The United States will introduce a new and comprehensive(綜合的) exam for students who seek to study in American and other English-speaking countries, Xinhua News Agency reported from New York.
The exam, which stands for a great change from the current English level test, was disclosed by Theresa Chang Wei Jen, associate director of the International Service of the US College Board, America’s leading educational organization.
The Advanced Placement International English Language (APIEL) will be offered for the first time throughout the world on May 10, 2002, said Jen.
However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL(Test of English as a Foreign Language), the GRE(Graduate Record Examination), or the IELTS(International English Language Testing System).
“I have never heard of such a test and I would prefer the IELTS if I need another exam,” said Xu Jingyan, a graduating student from Beijing University of Aeronautics and Astronautics, who wants to study in England and has already taken the TOEFL.
Most of Xu’s classmates have never heard of the APIEL. “The APIEL is designed for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada, and Australia.” said Jen.
The APIEL has been adopted, said Jen, because the TOEFL can no longer accurately reflect the abilities of students of using the English language comprehensively in an academic environment. Xinhua reported that a fairly large number of foreign students who earned high scores in TOEFL exam turned out to be very ordinary educational performers after admission.
Compared with the TOEFL, the APIEL measures a student’s ability to read, write, speak and understand English through testing his or her skills in listening comprehension, speaking with accuracy(精確) and resourcefulness, and writing with clarity and fluency(流暢), Jen said.
小題1:The United States will introduce a new exam because _______.
A．more and more students want to get further education in the USA
B．the Chinese people pay special attention to English studies with China’s entry into the WTO
C．the already existing exam systems seem to be far from perfect
D．it will bring the US government quite a lot of money
小題2:Which of the following statements is TRUE according to the selection？
A．It will take quite a period of time for people to accept the APIEL.
B．The TOEFL is more popular with the Chinese than the IELTS.
C．A student will have to take the APIEL if he or she wants to study in English—speaking countries from 2002.
D．Chinese students will prefer the IELTS rather than the APIEL even in the future.
小題3:The underlined word current in the second paragraph means _______.
A．modern B．present C．standard D．formal
小題4:Please decide which of the following would be the best title for this news report.
A．The Key to English-speaking Countries
B．The Four Skills in Learning English
C．TOEFL, IELTS and GRE to be Out of Date
D．New Exam Designed for Students

A study involving 8,500 teenagers from all social backgrounds found that most of them are ignorant when it comes to money. The findings, the first in a series of reports from NatWest that has started a five-year research project into teenagers and money, arc particularly worrying as this generation of young people is likely to be burdened with greater debts man any before.
University tuition fees (學費) are currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.
In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £ 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £ 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £ 10.000. Average debts for graduates are £ 12，363.
Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they arc to become responsible, forward-planning adults who manage their finances confidently and effectively."
Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweathcr. aged 15. from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.
1. Which of the following can be found from the five-year research project?
A. Students understand personal finances differently.
B. University tuition fees in England have been rising.
C. Teenagers tend to overestimate their future earnings.
D. The students' payback ability has become a major issue.
2. The phrase "to raise the ceiling" in paragraph 2 probably means "______".
A. to raise the student loans      B. to improve the school facilities
C. to increase the upper limit of the tuition     D. to lift the school building roofs
3. According to Stephen Moir, students_______.
A. are too young 10 be exposed 10 financial issues
B. should learn 10 manage their finances well
C- should maintain a positive attitude when facing loans
D. benefit a lot from lessons on personal finance
4. What can we learn from the passage?
A. Many British teenagers do not know money matters well
B. Teenagers in Britain are heavily burdened with debts.
C. Financial planning is a required course at college.
D. Young people should become responsible adults.

The Best of Friends
The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image(印象)of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team.” They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商議) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall.” I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.”Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework ,I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments,” Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
小題1:What is the popular images of teenagers today?
A．They worry about schoolB．They dislike living with their parents
C．They have to be locked in to avoid troublesD．They quarrel a lot with other family members
小題2:  The study shows that teenagers don’t want to ___
A．share family responsibilityB．cause trouble in their families
C．go boating with their familyD．make family decisions
小題3: Compared with parents of 30 years age, today’s parents___.
A．go to clubs more often with their childrenB．are much stricter with their children
C．care less about their children’s lifeD．give their children more freedom
小題4: According to the author, teenage rebellion____.
A．may be a false beliefB．is common nowadays
C．existed only in the 1960sD．resulted from changes in families
小題5:What is the passage mainly about?
A．Negotiation in familyB．Education in family
C．Harmony in familyD．Teenage trouble in family

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part －drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (遠距離的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (螞蟻) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
小題1:Watchers doubted if any of the vehicles could finish the race because        .
A．they did not have any human guidance
B．the road was not familiar to the drivers
C．the distance was too long for the vehicles
D．the prize money was unattractive to the drivers
小題2:DARPA organized the race in order to         .
A．raise money for producing more robotic vehicles
B．push the development of vehicle industry
C．train more people to drive in the desert
D．improve the vehicles for future wars
小題3:From the passage we know “robotic vehicles” are a kind of machines that         .
A．can do effortlessly whatever tasks living thing can
B．can take part in a race across 142 miles with a time limit
C．can show off their ability to turn themselves upside down
D．can move from place to place without being driven by human beings
小題4:In the race, the greatest distance one robotic vehicle covered was          .
A．about eight miles B．six miles
C．almost two miles D．about one mile
小題5:In the last paragraph, the writer implies that there is a long way to go         .
A．for a robotic vehicle to finish a 142-mile race without any difficulties
B．for a little child who has just learned to walk to reach the cookie on the table
C．for a robotic vehicle to deal with a simple problem that a little child can solve
D．for a little child to understand the importance of wiping apple juice off its face
