In the computer age, most of us take a broadband(寬帶)Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “l(fā)ast mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纖電纜) promise to bring extremely fast Internet connections to more users.
Still, the “l(fā)ast mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (跡象), it may not be too long before an Internet connection simply follows you wherever you go.
小題1:The underlined part “a catch” (in Paragraph 2) probably means “_____”.
A.a(chǎn) rare challengeB.a(chǎn) desirable planC.a(chǎn)n efficient deviceD.a(chǎn) hidden problem
小題2:What can we know from the third paragraph?
A.Internet connection has not been popular in most cities.
B.Internet service providers care about rural(農(nóng)村的)customers.
C.Computer is popular in developing countries.
D.It is hard to bring Internet access to users in remote areas.
小題3:Paragraph 4 mainly tells us that technological advancements _____.
A.make TV and telephone available everywhere
B.bring great change to people’s everyday life
C.make it possible for more people to use the Internet
D.bring faster Internet connections to users
小題4:What may eventually settle the “l(fā)ast mile” problem?
A.The broadband connection’s getting faster.
B.More and more Internet users.
C.more and more Internet connections.
D.The rapid progress in cell phone technology.

Think about the last time you felt a negative emotion—like stress, anger, or frustration. What was going through your mind as you were going through that negativity? Was your mind cluttered with (充斥) different kinds of thoughts? Or was it paralyzed, unable to think?
The next time you find yourself in the middle of a very stressful time, or you feel angry or frustrated, stop. Yes, that’s right, stop. Whatever you’re doing, stop and sit for one minute. While you’re sitting there, completely immerse yourself in the negative emotion.
Allow that emotion to consume you. Allow yourself one minute to truly feel that emotion. Don’t cheat yourself here. Take the entire minute—but only one minute—to do nothing else but feel that emotion.
When the minute is over, ask yourself, “Am I willing to keep holding on to this negative emotion as I go through the rest of the day?”
Once you’ve allowed yourself to be totally immersed in the emotion and really feel it, you will be surprised to find that the emotion clears rather quickly.
If you feel you need to hold on to the emotion for a little longer, that is OK. Allow yourself another minute to feel the emotion.
When you feel you’ve had enough of the emotion, ask yourself if you’re willing to carry that negativity with you for the rest of the day. If not, take a deep breath. As you exhale, release all that negativity with your breath.
This exercise seems simple—almost too simple. But, it is very effective. By allowing that negative emotion the space to be truly felt, you are dealing with the emotion rather than stuffing it down and trying not to feel it. You are actually taking away the power of the emotion by giving it the space and attention it needs. When you immerse yourself in the emotion, and realize that it is only emotion, it loses its control. You can clear your head and proceed with your task.
小題1:What should you do when you are into negativity according to the article?
A.Listen to some music.
B.Ignore it and do something else.
C.Just do nothing and truly feel that emotion.
D.Think about it and try to deal with it immediately.
小題2:The underlined word “immerse” (Paragraph 2) most probably means _____.
A.break downB.get rid ofC.cut offD.throw into
小題3:What’s the best title of this text?
A.Clear Your Mental Space.
B.Deep Breath, Trouble Away.
C.Try to Avoid the Negative Emotion.
D.Keep Holding on to This Negative Emotion as Long as Possible.
小題4:The author’s opinion towards negative emotion is _____.
A.doubtfulB.optimisticC.frightenedD.confused

Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants. They have been monitoring(監(jiān)測) communications between animals that cannot be heard by human ears.
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (聽得見的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
小題1:Why some elephants’ call is called “secret language”?
A.Because it can’t be heard by human ears.
B.Because it can only be heard by female elephants.
C.Because people don’t know its meanings.
D.Because people haven’t studied it completely.
小題2:By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out             .
A.where the elephants usually go
B.what the elephants’ growls really mean
C.how mother elephants raise baby calves
D.how elephants protect their babies.
小題3:A pregnant elephant uses inaudible growls to           .
A.show the location where she is staying
B.a(chǎn)sk for help when she losses her way
C.scare away the enemy
D.let others know she will have a baby
小題4:What is the passage mainly about?
A.The elephants can speak like people.
B.The wild elephants’ ways to fight against enemies.
C.The “secret language” between elephants.
D.The special life of female elephants.

Do your children always sit still and watch TV? If so, you should be very alert!
Nowadays, children watch television for long hours. They often spend evenings watching their favorite programs on TV. Sometimes they might stay up late to watch TV. Their addiction to television results in their not having time to play or do exercise. They should go outside with friends or spend time reading books. Moreover, watching television too much is harmful to their eyesight.
Researchers claim that attention deficit disorders in children are a result of watching too much television. They say that watching television leads to a developmental disorder in the part of the brain which is responsible for language skills.

Are you a team person? Are you at your best as part of a small, tightly united group of dedicated workers? If so, the future may hold more for you than you think.
High technology, some predicted, would make team work a thing of the past. That’s happening in those areas of business and data processing where one person and a computer can replace a team of workers.
But, elsewhere, teamwork is very much alive. High technology has led to a new type of teamwork in a number of fields, including advertising, scientific research, engineering design, architecture and ocean exploration. Through computer networking, scientists, engineers and technicians at different locations---often thousands of miles apart---can work on the same project at once. They can exchange ideas, try out different designs and test their results.
Examples? An engineering team can now design and try out a robot system, a new manufacturing process, or an entire factory before it is built. An architectural team can do the same with a building or a bridge. A medical team can simulate (模擬) a dangerous operation before performing it on a patient.
Of course, computer–assisted team effort doesn’t end with investigation and simulation. It now usually continues into actual design, manufacturing and testing. “Computer–aided design (CAD) and computer–aided manufacture (CAM) are breaking down barriers between traditional design and manufacturing functions,” explains Dr. Prakash Rao, an engineering manager at General Electric. “Interdisciplinary teams and engineers follow a product from concept to production. Everything is interconnected like a network.”
Sometimes a computer–aided effort can extend beyond production. A team that produces robots may use them to explore space and ocean depth. For high–technology team work, the future seems limitless.
小題1:The underlined part “hold more” most probably means to          .
A.maintain more chancesB.give more rights
C.make more regulationsD.store more information
小題2:According to the passage, the writer believes that         .
A.teamwork requires more use of computers than that of human beings
B.teamwork will be completely replaced by computers
C.the concept of teamwork is still alive and no longer the same as the past
D.high technology would make teamwork a thing of the past
小題3:The examples given by the writer in Paragraph 4 serve           .
A.to prove high technology has a promising future
B.to explain his idea of new type of teamwork is reasonable
C.to show that it tends to be an end to teamwork soon
D.to indicate the computer—assisted team effort just means investigation and simulation.
小題4:Which of the following statements is NOT true according to the passage?
A.Many fields of science and technology are now using computers effectively.
B.No details are given in the passage about barriers between traditional design and manufacturing functions.
C.Experts from different fields have to cooperate to develop a product from concept to production.
D.High technology is nothing but a new type of teamwork plus CAD and CAM.
小題5:The author’s attitude to towards the introduction of the computer to teamwork is of         .
A.objectionB.indifferenceC.supportD.doubt

The rising sea waters caused by global warming have inspired a Russian architect to design a hotel that could be built on water as well as land.The eco-friendly “Ark” could be constructed in just a few months anywhere in the world, the designer says.   
It’s called “The Ark”,but looks more like a ship sitting upside down on the water.A new design by Russian architect A1exander Remizov challenges the tradition of land-based hotel and would provide a shelter in the future—should the world face a modern-day flood as described in the Bible
The building of the hotel could be fast and simple.“Prefabricated(預制裝配的)section could be put together in three to four months,” Remizov said. The versatile(萬能的)structure could be constructed in most corners of the earth, even in earthquake-prone areas.Constructing “The Ark"—which would include 14 000 square meters of living space???would cost roughly the same as building an energy-efficient house. The self-supporting structure would be built around a central post, connecting wind generators and heat pumps on its roof with the basement,where solar,wind,and thermal(熱量的)energy could be stored and turned into electricity. Remizov has designed the building without glass,choosing instead the lasting and self-cleaning foil(箔)that could defend itself against rough weather conditions.That foil would be fastened to metals,which would also collect rainwater.The building would also feature an indoor jungle, creating its microclimate.
小題1:What’s the purpose of designing “The Ark,?” 
A.To prevent flood happening.B.To draw the public’s attention
C.To secure people from flood.D.To attract more tourists.
小題2:Which of the following might be the shortest time to make the parts of "The Ark”?
A.14 months.B.3 months.C.4 months.D.7 months.
小題3:What is the main difference between the hotel designed by Ale Remizov and other hotels?
A.It can be built on water.B.It is energy-efficient.
C.It is eco-friendly.D.It has enough living space.
小題4:What characteristics will the new hotel have?
A.A climate with no rain will form around the hotel.
B.The material can protect the hotel from bad weather.
C.A power station will be built in the hotel.
D.Bricks will be used as the materials instead of glass.

While success is surely sweeter than failure, it seems failure is a far better teacher, and organizations that fail miserably often flourish (繁榮) more in the long run, according to a new study by Vinit Desai, assistant professor of management at the University of Colorado Denver Business School. Researchers have found that people missing their goals perform much better in the long run. That is because they gain more knowledge from their failures than their successes and the lessons are more likely to stay longer in their minds.
“We found that the knowledge gained from success was often fleeting while knowledge from failure stuck around for years,” said professor Desai, who led the study. “But companies often ignore failure. Managers may fire people or turn over the whole workforce while they should treat the failure as a learning opportunity.”
Prof Desai compared the flights of the space shuttle Atlantis and the Challenger. During the Atlantis flight last year, a piece of insulation (絕緣體) broke off and damaged the left solid rocket booster (助推火箭) but didn’t influence the program. There was little investigation. The Challenger was launched next and another piece of insulation broke off. This time the shuttle and its seven–person crew were destroyed. The disaster led to a major investigation resulting in 29 changes to prevent future disasters.
The difference in response in the two cases came down to this: Atlantis was considered a success and the Challenger a failure.
“Despite crowded skies, airlines are extremely reliable,” he said. “The number of failures is extremely small. And past researches have shown that older airlines, those with more experience in failure, have a lower number of accidents.”
Prof Desai doesn’t recommend finding out failure in order to learn. Instead, he advises organizations to analyze small failures to collect useful information rather than wait for major failures.
小題1: Why did experts pay little attention to the problem of Atlantis?
A.Because it worked perfectly.
B.Because the right booster was still OK.
C.Because nothing serious happened then.
D.Because fewer people died in the flight.
小題2:Fewer accidents happen to older airlines in that ________.
A.their planes couldn’t fly high in the sky
B.they gained much from experience in failure
C.their planes were often checked by the experts
D.they were unpopular among passengers
小題3:The passage is written mainly to ________.
A.show failure is a better teacher than success
B.explain why Challenger failed
C.introduce something about Prof Desai
D.tell managers how to achieve success
小題4: Which writing strategy is NOT used in developing the passage?
A.Giving definitions.
B.Making comparisons.
C.Analyzing causes.
D.Providing different examples.
