Electrical devices（儀器）could soon use power make by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking . British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this , the device helps with the slowing sown movement of the leg.  The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device . Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers（起博器）. It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.
The developers hope the device will one day help developing countries. Nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag . But the bag requires the walker to carry a load of twenty to thirty kilograms.
小題1:The second paragraph mainly talks about       .
A．who developed the device
B．how the device works
C．several possible uses for the devices
D．how much electricity the device can produce
小題2:What is the disadvantage of the experimental version of the device?
A．It is too heavy for the walker to bear
B．It is too complex for people to use
C．It is too expensive for most people to afford
D．It will slow down one’s walking speed.
小題3:Compared with the device designed by Larry Rome ,this new device       .
A．produces power without adding more loads to the walker
B．can produce more power in a much shorter time
C．needs to be equipped with a battery
D．can help the walker walk faster
小題4:From the passage, we can learn that the electrical device can       .
A．help housewives operate the washing machine
B．make it much easier for us to go online
C．produce more electricity than that invented by Larry Rome
D．be applied to operate heart pacemakers
小題5:What would be the best title for the passage?

At the moment, there are two reliable ways to make electricity from sunlight. You can use a panel of solar cells to create the current directly, by liberating electrons from a semiconducting material such as silicon. Or you can concentrate the sun’s rays using mirrors, boil water with them, and employ the steam to drive a generator.
Both work. But both are expensive. Gang Chen of the Massachusetts Institute of Technology and Zhifeng Ren of Boston College therefore propose an alternative. They suggest that a phenomenon called the thermoelectric（熱電）effect might be used instead—and they have built a prototype（原型）to show that the idea is practical.
Thermoelectric devices are not new. They are used, for example, to capture waste heat from car engines. They work because certain materials generate an electrical potential difference within themselves if one part is hotter than another. That can be used to drive a current through an external circuit.
The reason thermoelectric materials have not, in the past, been applied successfully to the question of solar power is that to get a worthwhile current you have to have a significant temperature difference. (200℃ is considered a good starting point.) In a car engine, that is easy. For sunlight, however, it means concentrating the heat in some way. And if you are going to the trouble of building mirrors to do that, you might as well go down the steam-generation route, which is a much more efficient way of producing electricity. If the heat concentration could be done without all the equipment of mirrors, though, thermoelectricity’s inefficiency would be balanced by the cheapness of the equipment.
In their view, three things are needed to create a workable solar-thermoelectric device. The first is to make sure that most of the sunlight which falls on it is absorbed, rather than being reflected. The second is to choose a thermoelectric material which conducts heat badly but electricity well. The third is to be certain that the temperature gradient（梯度）which that badly conducting material creates is not wasted by poor design.
小題1:The following methods can be adopted to make electricity from sunlight EXCEPT         .
A．putting a panel of solar cells into use
B．concentrating sun’s rays with mirrors
C．creating a solar-thermoelectric device
D．building a practical solar prototype
小題2:Why was the application of thermoelectric materials a failure in the past?
A．Because it’s hard for them to build enough mirrors to make it work.
B．Because 200℃ was hard to reach at that time even in a car engine.
C．Because of the failure of having a significant temperature difference.
D．Because it was hard to focus the sun’s rays with equipment of mirrors.
小題3:Which of the following is the best title for this passage?
A．Thermoelectric Device --- the Best Method of All
B．A New Method of Making Electricity from Sunlight
C．How to Create a Workable Thermoelectric Device
D．Solar Power --- a New Energy Trend in the Future

Online Communication
In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.
But a story about online communication changed my mind.
An old man, who suffered a lot from Parkinson’s disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.
I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities（能力） that few other products can match.
E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn’t want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office.
Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing junk ads.
Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I’m sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting… even in the world of modern communication.
As I listen to the sound of the modem(調(diào)制解調(diào)器), I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.
小題1:What is the most probable meaning of the underlined word “junk” in paragraph6?
A．old and uselessB．New and usefulC．Short but valuableD．Long but clear
小題2:What does the writer think of online communication?
A．It should replace old-fashioned letters completely.
B．It is perfect and always does good to you.
C．It is extremely useful and convenient, but it may be inconvenient or even harmful.
D．It does more harm than good.
小題3:What caused the writer to become interested in E-mail and online communication?
A．The sound of the modem.B．His own illness.
C．The changing of his life.D．A sick old man’s experience.
小題4:According to the writer, traditional means of communication will never disappear because ________.
A．they are convenient and popular though they are slow
B．they help to keep the friendly relationship between people
C．most people cannot keep up with the development of technology
D．modern means of communication does too much harm
小題5:How did the sick old man keep in touch with his family members?
A．With the help of his computer.B．By writing letters with his pen.
C．By making telephone calls.D．By visiting them regularly.

If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.       knows this, but nobody would think of     the fact.
Yet there are many people who        to know that the memory works in the same way. When someone says that       has a good memory, he       means that he keeps his memory in practice     exercising it very     , either consciously or unconsciously. When someone else says that his memory is     , he means that he does not give it enough      to become strong. The position is exactly the same as that of       people, one of      exercises his arms and legs by playing ball, while the other       in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own      , But if he tells us that he has a poor memory,      of us think that his parents are to blame, or that he is just     , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,       all of us can improve our strength and our memory by the same means that      .
Have you ever       that people who cannot read or write usually have      memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
In a word, if you want to have a good memory, do practice       things。

It seems that many college graduates are unsure of what to do with their lives, so they jump back into the college scene by default(違約). But graduate school is costly, time consuming and requires a lot of in-depth study, and also parents will lay down more money and banks will supply more student loans.
However, there are some students who should be pursuing graduate degrees. Teachers, lawyers, doctors, professors and ministers are a few examples of those who will benefit from class work past a bachelor’s degree. Their professions call for additional courses and more specialization and therefore higher education is a must. Still, all students in general should not adopt the idea that graduate school is necessary for individuals who want to make more money. Working hard right after college can lead to promotions in the future. It seems that it does more good to network or internship（實習(xí)）with professionals while pursing a bachelor’s degree than it does to complete a master’s and distant oneself from the world of work.
If a student graduates with a four-year degree and immediately enters the work force , he will most likely start an entry-level pay. In a couple of years this employee will gain seniority and experience, therefore increasing their chance for pay rise. He will learn the information at his job-site that he did not learn in school. His bachelor’s degree loan can be immediately chipped away ,and his maturity level can increase as real work related responsibilities set in. But, if the student pursues a master’s degree, he may be able to demand more pay initially when he finally goes job hunting, but years of serious money making as well as work experience will already be lost.
Students should not shy from the workforce just because uncertainty follows graduation. Those who pursue a graduate degree just because they do not want to leave school and because they view the “real world” as scary should think again. Using graduate studies as a hiding place from the full-time job is a waste of time.
小題1:College graduates who go to work can _____ than those who pursue graduate degrees.
A．make more money in the futureB．a(chǎn)cquire more experience
C．get a better jobD．become more responsible
小題2:The underlined words “chipped away” can most possibly be replaced by_______.
A．given outB．set downC．thrown awayD．paid off
小題3:What would be the best title for the passage?
A．College graduates shouldn’t pursue graduate degrees
B．College graduates should think twice
C．How can college graduates make more money?
D．Students use graduate school to avoid reality

It is often said that man has become the enemy of our planet. This is no exaggeration(夸張), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外線)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（規(guī)模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.
小題1:Which of the following is a reason for the cutting and burning of forests?
A．To build houses for more population. B．To have land for agriculture.
C．To export trees to other countries.D．To build industrial plants.
小題2:The holes in the ozone layer are largely due to________.
A．man’s research activities B．the greenhouse effect
C．the ultraviolent D．harmful chemicals
小題3:Why don’t some countries care about the problem of the environment?
A．They don’t want to put their lives in danger.
B．They just don’t know how to solve the problem.
C．They haven’t realized the seriousness of the problem.
D．They don’t want to break their international commitment.
小題4:66. What is the author’s attitude towards the future of the environment?
A．Hopeful. B．Unconcerned C．Doubtful D．Objective

Today, there are many chances for those who wish to continue their education. However, nearly all require some break in one’s career in order to attend school full time.    　　
Part-time education, that is, attending school at night or for one weekend a month, tends to drag the process out over time and puts the completion of a degree program out of reach of many people. Additionally, such programs require a fixed time commitment which can also impact negatively on one’s career and family time. 
Of the many approaches to teaching and learning, however, perhaps the most flexible (靈活的) is that called distance learning. Distance learning is an educational method which allows the students the flexibility to study at his or her own pace to achieve the academic goals which are so necessary in today’s world. The time required to study may be set aside at the student’s convenience. Additionally, the student may enroll in distance learning courses from actually any place in the world, while continuing to pursue their chosen career. Individual assistance may be available via regular airmail, telephone, fax machine, teleconferencing and over the Internet.
Good distance learning programs are characterized by the inclusion of a subject evaluation tool with every subject, so a student doesn’t need to travel away from home to take a test. Another characteristic of a good distance learning program is the equivalence (等同) of the distance learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is employed. The individuality of the professor/student relationship is another characteristic of a good distance learning program. In the final analysis, a good distance learning program has a place not only for the individual student but also the company or business that wants to work in partnership with their employees for the educational benefit, professional development, and business growth of the organization. Supporting distance learning programs for their employees gives the business the advantage of retaining (留住) career-minded people while contributing to their personal and professional growth through education. 　　
小題1:According to the passage, which of the following is NOT a disadvantage of part time education?
A．It requires some break in one’s career. 　　
B．It tends to last too long for many people to complete a degree program.　　
C．It affects one’s career.　　
D．It gives the student less time to share with the family.
小題2: Which of the following is NOT an advantage of distance learning?  　
A．The student may choose his or her own pace.　
B．The student may study at his or her convenience.　　
C．They can pursue their chosen career while studying.　　
D．Individual assistance comes through regular airmail, telephone and fax machine.
小題3:What benefit will distance learning program bring to a business?   　　
A．Attracting more talented people.　　
B．Good image of the business.　　
C．Better cooperation with universities.　　
D．Further training of employees and business growth.
小題4: Good distance learning program have the following characteristics EXCEPT _______.    　　
A．distance learning course is the same as students taking courses on campus　
B．the diploma or degree should be the same as on campus study　　
C．professor-student relationship is strictly one to one all through the course　　
D．includes subject evaluation tool
小題5:What benefit will distance learning bring to an employee of a business?    　　
A．Higher salary.　　
B．Professional growth.　　
C．Good impression on the employer.　　
D．Good relationship with the employer.

More than 30 million kids buy school lunch each day. This year, many schools raised lunch prices to fight raising costs. Students pay about $2 a meal now. That is 27 cents more than last year. But they still get a good deal. The average cost for schools to produce one meal has gone up 30 cents, and is now $3. 
So, how do schools neither make money nor lose money? To start, the government pays for a small part of the difference. Schools have to make up the rest. Peggy Eller, a leader of school nutrition (營養(yǎng)) service in Hudson, Wisconsin, said her district is cutting costs by using fewer paper products and serving smaller portion(份額). Well, portion control is one key to healthful eating! 
The push for more healthful food has grown in recent years. One in five kids aged 6 to 19 is overweight. Being overweight can cause health problems. Many states passed laws that require schools to serve nutritious meals. 
Since 2004, more than 90% of all U.S. Schools have removed the fat from lunches. Foods high in fat, salt and sugar have been replaced by low-fat milk, fresh fruits and vegetables. These new items on lunch menus have encouraged kids to change their eating habits. “It makes easier to try new things at home, “said Savanna Mackey, a Florida fifth-grader.  
Students need healthful meals to grow strong and do well in school. “Rising prices won’t stand in the way,”says school nutritionist Jane Thornton. “We’ll just be more clever in how we do things.”
小題1:In the first paragraph, the author aims to tell us        .
A．the large number of kids buying school lunch
B．the average price of school lunch
C．the school's ways to deal with school lunch
D．the fact of school lunch's getting more expensive
小題2:Many school districts raised lunch prices because        .
A．there is less healthful food on the menus
B．the cost of food has gone up
C．kids often forget to bring lunch money
D．some school dining-halls are serving smaller portions
小題3:According to Paragraph 4, Savanna Mackey      .
A．doesn't like the new items on the lunch menus
B．a(chǎn)lways enjoys foods like fresh and vegetables
C．becomes interested in eating healthy food at home
D．prefers eating at school to eating at home
小題4:What can be inferred from the passage?
A．American schools solve the problem of high food prices by themselves.
B．American schools are very concerned about their students’ health.
C．Almost all schools are forced by the government to serve healthy foods.
D．American childhood overweight is mainly caused by the present lunch foods.

Have you ever seen any students whose trousers hang so low that you can see their underwear? What do you think of that? Fashionable? Some of today’s teenagers are big fans of such a look. But recently this trend has been at the center of an argument in Italian middle schools. The headmaster of a school in central Italy has asked students to stop wearing low-rise jeans that expose underwear and parts of the body. His request came after a class trip, when he saw one boy's baggy trousers slide to his feet. He pointed out that this way of dressing is not suitable for school. But in Italy, a nation that takes fashion very seriously, the suggestion caused a debate among parents, teachers and students. The issue is whether the headmaster's request will limit students' freedom— or whether dress in Italian schools is too casual. A parents' group praised the move in favor of good taste, while others advised schools to stop worrying about fashion and fix up old school buildings. “We do not want to kick fashion out,” the headmaster explained, “but extremes of fashion like this are not right in school.” Many other schools have now requested that their students also stop wearing such trousers. Most students have simply ignored the request. Ludovica Gaudio, 14, wore extremely low trousers exposing orange underwear in class. It was cold, so she wore a matching orange scarf. Another 14-year-old said she would probably respect the request, simply for practical reasons. “I don't really feel comfortable in those sort of jeans，” said Sarah Lattanzi, “in winter, when dressed like that, it's quite cold and I am afraid my stomach will ache.”
小題1:What led to the argument in Italian middle schools？______
A．Students' craze for fashions.B．Clothes that are too exposing.
C．Students' ignoring dress codes.（規(guī)則）D．Students' underwear.
小題2:Which of the following supports the headmaster's request?___
A．Fashion should be taken seriously.
B．Fashion should not be followed in school.
C．Students should have their freedom in choosing what they wear.
D．Students should be encouraged to have good taste in clothes.
小題3: The argument against the headmaster's request is that ______.
A．dress in Italian schools is too casual
B．fashion should not be followed in school
C．schools should pay attention to things more important than students' clothes
D．low-rise jeans can do harm to youngster's health
小題4:The purpose of this story is to ________
A．show Chinese students that wearing very fashionable clothes in school is under attack in other countries, too.
B．show that dress code is necessary even in a country like Italy
C．let us see that Italian students react differently to schools' requests.
D．tell us that a debate started in Italian middle schools over the way students dress in School
