The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, 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 isolated Arctic regions explorers have reported being free from colds until coming into contact 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(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奧斯維辛集中營), naked and starving, 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 long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty 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 the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this 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 suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(癥狀).
【小題1】The writer offered _______ examples to support his argument.

Researches at Johns Hopkins University's. Applied Physics laboratory ( APL) in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings.
Roho Sally has two long arms with human-like hands. She can use her fingers to pick up small objects .examine them in detail and do most things that human hands can do Each finger contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .
Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics Program. "The purpose of that program is to develop prosthetic arms that have all the capability of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "
It was a difficult job. Mr. McLoughlin says the device had to have many small motors to。 have the ability to do what a human hand does; It also needs to have human-like strength. The thumb was especially difficult because it permits the hand .to hold objects. And everything had. to fit into a space about the size of a human hand.
The next problem .he says .was to figure out how to control the artificial hand. " So we had to figure out how to make the connection between the brain and this arm.
For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses. The glasses permit the operator to see the robot's hands .even though they are far away.
Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is not ready for everyday application .but he predicts that within five years we will see some won- derful improvements.
【小題1】The underlined word " defuse" in Paragraph 2 is closest in meaning to "_________".
| A．remove | B．discover | C．equip | D．produce |
| A．They are expected to function as well as natural ones. |
| B．They have many large motors controlled by robots. |
| C．They have human-like strength to control the robot. |

Julie was preparing for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”
【小題1】Why does the author mention Kelly’s experience in the first paragraph?
| A．To inform us that mobile phones are useful. |
| B．To introduce the topic for discussion. |
| C．To warn us that we should be careful. |
| D．To tell us we should get phones ready for a trip. |

The energy crisis has made people aware of how the careless use of the earth’s energy has brought the whole world to the edge of disaster. The over-development of motor transport, with its increase of more cars, more traveling, has contributed to the near-destruction of our cities and the pollution not only of local air but also of the earth’s atmosphere.
Our present situation is unlike natural disasters of the past. Worldwide energy use has brought us to a state where long-range planning is vital. What we need is not a continuation of our present serious state, which endangers the future of our country, our children, and our earth, but a movement forward in order to work rapidly and effectively on planetary problems.
This country has been failing back under the continuing exposures of loss of morality and the revelation(揭露) that lawbreaking has reached into the highest place in the land. There is a strong demand for morality to turn for the better and for some devotion that is vast enough and yet personal enough to enlist the devotion of all. In the past it has been only in a way in defense of their own country and their own benefits that people have been able to devote themselves wholeheartedly.
This is the first time that we have been asked to defend ourselves and what we hold dear in cooperation with all the other people of this planet, who share with us the same endangered air and the same endangered oceans. There is a common need to reassess our present course, to change that course and to employ new methods through which the world can survive. This is a priceless opportunity.
To grasp it, we need a widespread understanding of nature if the crisis we and the world are facing is no passing inconvenience, no byproduct of the ambitions of the oil-producing countries, no environmentalists’ only fears, no byproduct of any present system of government. What we face is the result of the invention of the last four hundred years. What we need is a transformed life style. This new life style can flow directly from science and technology, but its acceptance depends on a sincere devotion to finding a higher quality of life for the world’s children and future generation.
【小題1】Which of the following has nearly destroyed our cities?
| A．The loss of beliefs and ideas. |
| B．More of law-breaking. |
| C．Natural disasters in many areas. |
| D．The rapid growth of motors. |
| A．seriousness of this crisis |
| B．ineffectiveness of laws |
| C．similarity of the past to the present |
| D．hopelessness of the situation |
| A．Disregard for law. | B．Lack of devotion. |
| C．Lack of understanding. | D．Destruction of cities. |
| A．make a recommendation for a transformed life style |
| B．limit ambitions of the people of the whole world |
| C．demand devotion to nature and future generation |
| D．encourage awareness of the decline of morality |

Koala bears as pets might be appealing to many of us. However, there are quite a few points to consider even before thinking of adopting one.
Koala bears are one of the most lovely Australian animals. In certain cases where the koala has been raised by hand, they have turned out to be quite affectionate pets. These people tied a piece of fur to a pillow and placed it beside a joey (a baby kola) as a substitute (替代物) for the mother koala. This trick seemed to work well with the baby koala. However, it is a known fact that human handling causes stress to koalas. In my personal opinion, this aspect clouds the fact that koala bears can be tamed (馴服).
In Australia the koala is a priority animal as far as conservation status assessment is concerned. It was hunted to near extinction (滅絕) for its fur. In fact the koala had been wiped out from South Australia in the 1920s. However, rehabilitation efforts have brought the animal back in the state. As for the Australia government, the koala is not a threatened animal, but the US government does list the koala as one.
Although they may live in 40 to 60 kinds of eucalyptus trees, they prefer only 10 to 14 specific kinds. Koalas sleep for most part of the day, which is about 16 to 18 hours, and for most of their waking hours all they do is eat. Koala bears eat the leaves of eucalyptus trees. A full-grown koala can eat almost 2 to 3 pounds of leaves in a day. Despite their slow movements and sweet look, koala bears can be vicious when hungry. Other than this, there are the stress caused to koalas due to human handling and the fights that start in koalas.
Almost everyone finds koalas lovely in the zoo. However, as far as having koala bears as pets is concerned, there are legal issues to consider. Other than that, being able to provide for its diet and habitat is another point that needs some attention before any law legalizing their adoption as pets is passed.
【小題1】What’s the author’s attitude towards people raising the koala?
| A．Optimistic. | B．Grateful. | C．Cautious. | D．Enthusiastic. |
| A．To get its fur. | B．To eat its meat. | C．To wipe it out. | D．To have it for fun. |
| A．fierce and dangerous | B．patient and friendly |
| C．a(chǎn)fraid and defensive | D．lovely and interesting |
| A．koala bears tend to live in groups |
| B．koala bear care can be very demanding |
| C．koala bears are not particular about their food |
| D．koala bears are the No. 1 threatened animal in the US |

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 |
| 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. |
| 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 |
| 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 |

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
The researchers considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
【小題1】What is the best title of the passage?
| A．The older a person is, the more stressed he feels. |
| B．The more lighthearted a person is, the happier he is. |
| C．The older a person is, the more clever he grows. |
| D．The older a person is, the happier he grows. |
| A．only when people get older, will they feel happier |
| B．older people usually have no worries in their life |
| C．stress levels among the youngest are the highest of all |
| D．older people are more likely to be thankful in life |
| A．When people get older, they can’t remember bad experiences. |
| B．When people get older, they have no young children to care about. |
| C．When people get older, they learn to adjust their feelings. |
| D．When people get older, they don’t care about their feelings. |
| A．A Gallup organization. |
| B．A popular science magazine. |
| C．A university in New York. |
| D．A research institution |
| A．Advice to the young people on how to keep happy. |
| B．Advice to the old people on how to live longer. |

How would you like to sleep with one half your brain asleep and the other half awake? Dolphins sleep this way. Recently, scientists at Indiana State University have discovered that ducks sleep this way too. They found that ducks sleep half awake so they can rest and watch for danger at the same time.
After putting their ducks in a row and videotaping them, some researchers found ducks on the end of each row spent more time asleep with one eye open, apparently looking for predators.
“The more the ducks felt threatened, the more they slept with one eye open,” said lead author Niels C. Rattenborg, a graduate student at Indiana State University, Terre Haute. “The unique aspect is not that they do it, but that they control it. When they sleep at the edge of a group, they tend to realize greater danger, so they spend more time sleeping with one half of their brain.” Ducks with one eye open were still awake enough to detect predators, said the authors of the study, which appears today in the journal Nature.
The researchers studied four groups of four ducks held in plastic boxes, which were arranged in a row. Ducks on the end were found to sleep with one eye open 31.8 per cent of the time, compared to 12.4 percent of the time for ducks in the central position.
Also, ducks in the central position did not open one eye more than the others, while ducks on each end kept the eye facing away from the group open 86.2 per cent of the time. Brain wave readings of the ducks showed that the half of the brain receiving signals from the closed eye indicated that half of the brain was sleeping. Signals from the half of the brain receiving signals from the open eye showed a state between fully awake and asleep.
【小題1】The under lined word “predator” is most likely to mean .
| A．a(chǎn)n animal that is likely to be friends with ducks |
| B．a(chǎn) human being who looks after and feeds ducks |
| C．a(chǎn) scientist who does research work on animals |
| D．a(chǎn)n animal that hunts, kills and eats other animals |
| A．they are looking for food |
| B．they are watching out for danger |
| C．they want to enjoy the scenery |
| D．they are unique in their sleeping habit |
| A．Ducks with one eye open at the edge can still enjoy a certain degree of sleep. |
| B．Ducks with less sense of duty usually choose to stay in the center of a row. |
| C．Ducks on the northern end of a row would keep their eye facing the south open. |
| D．A video tape recorder was the only electronic device used in the experiment. |
