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.

One day, a teacher was speaking to a group of students about how to manage time. He gave such an interesting example that his students would never   26  .
He put a wide-mouth jar(罐) on the table. Then he    27  some rocks and carefully placed them into the jar, one at a time. When   28  rocks would fit inside, he   29  , “Is this jar full?”
Everyone in class shouted, “Yes.” “Really?” The teacher pulled out a bag of small stones. He put   30  small stones in and shook the jar. The small stones went   31  into the spaces between the big rocks. He then asked the group   32  , “Is this jar full?”
“Probably not,” one of them answered. “Good!” the teacher replied. He brought out a box of sand and   33  some sand on the jar and it went between the rocks and small stones. Again he asked the   34  question, “Is this jar full?
“No,” the class shouted. Once more the teacher said, “Good.” He poured a cup of water into the jar   35  it was full. The he asked, “What is the point here?” One student   36  his hand and said, “The point is that if you try really hard, you can   37  put more things in.”
“No,” the teacher replied, “that’s not the   38  . What I want to tell you is that if you don’t put the big rocks in first, you will never get others in at all.   39  are the ‘big rocks’ in your life?

Christmas Eve means a warm get-together with friends, a candlelight dinner, or perhaps a celebration at a pub for students. But, for Cai Yingjie, the night has a different meaning: helping beggars（乞丐）and the homeless(people without homes).
Cai, who is a student in journalism at Tsinghua, could be found at Beijing’s Wudaokou Light Railway Station that special evening. When she saw an old beggar, she took the cold, rough hands of the woman with her warm, clean hands, and gave the woman some warm bread and helped her put on a pair of new gloves.
The woman was surprised for a few seconds, then burst into tears, saying “for the first time I feel respected”.
Cai said, “A beggar’s life is very hard. That’s why I want to help them.”
Cai was one of 14 Tsinghua students spending Christmas Eve among the poor. They walked in the cold wind along the streets from 4 to 7 pm on Friday, visiting 15 beggars in Beijing’s Haidian District.
They brought bread and gloves with them, and stopped to greet beggars and offer them some of the warm food. Each beggar greeted them with a look of surprise.
“I know the activity can’t help much, but it’s meant to show our respect and care for beggars and the homeless who have been neglected for so long,” said Sun, head of the group. “And Christmas is a good time for that.”
小題1:What does Christmas Eve mean to the 14 Tsinghua students?

A．Taking 15 beggars to Tsinghua.

B．Getting together with friends.

C．Showing care to the beggars and the homeless.

D．Selling bread and gloves to the beggars.

小題2:What does the beggar mean by saying “for the first time I feel respected”?

A．The beggar has been waiting for Cai for long.

B．The beggar hasn’t been shown care for so long.

C．The beggar has been respecting Cai for a long time.

D．This is the first time the beggar has seen Tsinghua students.

小題3:What did each beggar feel when they received greetings?

A．Sad.	B．Amazed.
C．Frightened.	D．Proud.

小題4:The word “neglected” in the last passage means _______.

A．protected	B．found
C．taken care of	D．given no enough care

There were times it was only schoolchildren who felt sick before they got their grades. But now teachers in Germany are scared, too, as they are being graded by their students.
Many teachers are opposed to it. They don’t mind being evaluated(評價). But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users. On the website www.spickmich.deduring the past four months students have posted evaluation of 100,000 teachers.
The teachers are graded on categories such as “motivated”, “good instruction”, “easy examinations”, or even “sexy”. Many teachers think that their privacy has been violated.
The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction. Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers. On a grading scale of one to six, the teachers’ average grade is 2.7 and it has been improving lately. He often says the impression is that students are bullying（威嚇） their teachers. But there is also bullying of the students by teachers.
“Teachers must also learn to live with criticism,” he added. But still, the website is not totally immune from manipulation(操縱), as one teacher near the northern city of Hanover recently proved. He registered himself on the website as a student and then rated his own teaching colleagues highly. Within a few days, seven of his colleagues were listed in the top 10 ranking of Germany’s best teachers.
小題1:Many teachers are opposed to the website because_____.

A．their privacy has been violated	B．they are afraid of being assessed
C．their evaluations are unfair	D．the results are not satisfying

小題2:We can infer that the founder of the website intended to _____.

A．get the students to know their teachers better

B．conduct a survey on teachers’ performance

C．help the teachers to improve their teaching

D．change the teachers’ ways of giving instructions

小題3:From what the teacher in Hanover did, we can infer _____.

A．he intended to help his colleague

B．there was some disadvantage of the website

C．his colleagues were more popular than him

D．he wanted to know how he was evaluated

Every year in the first week of English class, some students inform me that writing is too hard. They never write, unless homework requires it. They find the writing process painful and difficult.
How awful it is to be able to speak in a language but not to write in it, especially with its rich vocabulary. Being able to speak but not write is like living in an enormous mansion and never leaving one small room. When I meet students who think they can’t write, I know, as a teacher my duty is to show them the rest of the rooms. My task is to build fluency and accuracy while providing the opportunity in any writing activity to enhance（增強）the moral and emotional development of my students.
One great way to do this is by having students write in a journal in class every day.
Writing ability is like strength training. Writing needs to be done just like exercise; just as muscles grow stronger with exercise, writing skills improve quickly with writing practice daily. I often see a rise in student confidence and performance after only a few weeks of journal writing.
Expressing oneself in writing is one of the most important skills I teach to strengthen the whole students. When my students practice journal writing, they are practicing for their future academic, political, and emotional lives. They build skills so that some say they might write a great novel, a piece of sorely needed legislation（法規(guī)）, or the perfect love letter. That they write in their journals every day puts them a step closer to fluency, eloquence（雄辯）and command of the language.
小題1:What is the purpose of the passage?

A．To encourage students to keep a journal every day.

B．To analyze students’ problems in learning languages.

C．To stress the importance of writing in language learning.

D．To introduce an effective way of improving students’ writing.

小題2:The underlined phrase “an enormous mansion” in Paragraph 2 refers to students’       .

A．writing opportunity	B．large house
C．large vocabulary	D．emotional life

小題3:In the author’s view, what can students benefit from the journal writing?

A．It is beneficial to students’ future career.

B．It can make students more emotional.

C．It is helpful to students’ homework.

D．It can enlarge students’ vocabulary.

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 challenge

B．a(chǎn) desirable plan

C．a(chǎn)n efficient device

D．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.

Motherhood may make women smarter and may help prevent dementia(癡呆) in old age by bathing the brain in protective hormones(荷爾蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s (早老癡呆癥). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy (懷孕) are protecting the brain, including estrogen (雌激素), which we know has many neuroprotective (保護神經(jīng)的) effects,” Kinsley said.  
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改變) to the brain.”
小題1:How do scientists know “Motherhood may make women smarter”?

A．Some researchers have told them.

B．Many women say so.

C．They know it by experimenting on rats.

D．They know it through their own experience.

小題2:What does the phrase “l(fā)itters of pups” mean in the second paragraph?

A．Baby rats.

B．Animals.

C．Old rats.

D．Grown-up rats.

小題3:What can protect the brain of a woman according to the passage?

A．Estrogen.	B．The hormones of pregnancy.
C．More exercise.	D．Taking care of children.

小題4:“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?

A．The experiments on the rats have nothing to do with humans.

B．The experiments on the rats are very important for animals.

C．The experiments on the rats are much the same on humans.

D．The experiments on the rats are much the same on other animals.

When people talk of a virus these days, chances are that they are talking about computer virus that have the power wipe out all the valuable work people may have stored in their computers. Imagine, the virus has the power to make military systems, giant banks, airports, hospitals and traffic system come to stop!
What does a computer virus do? It targets electronic objects that are programmed. The virus spreads through connections between these electronic objects. For virus spreading experts, e-mail is a favorite method of sending their destructive (破壞性的) weapon.
But scientists warn that this is not the worst that can happen. There is more. People are also connected through phones. The next virus may actually target mobile phones, especially those that are programmed to do many tasks apart from just communicating. It would then be easy for a virus to infect those programs and create major disorder.
For example, these virus may have the power to record your phone conversations and make others hear them. They create problems with your electronic money accounts, or they could create a mountain of telephone bills for calls you never made. And that would be a disaster. A report on this was published in the New Scientist recently. 
One way out would be to have simpler phones with not so many different functions. This would mean there would mean there would be fewer programs for the virus to attack. But mobile phone producers are in a fix. People on longer want an electronic item to perform just one task. They want more and more functions added. That would mean more software programs to make the mobile phone perform all those functions. And that means the possibility of more viruses.
小題1:It can be inferred from the passage that ______.

A．computer viruses are not so as destructive as mobile phone viruses

B．people should be careful when receiving e-mails

C．people find it difficult to use electronic equipment correctly

D．having electronic money accounts brings people a lot of convenience

小題2:Which of the following shows that your mobile phone is infected with a virus?

A．You can’t hear the person who answers the phone clearly

B．You can’t send e-mails with your mobile phone

C．your phone bill increases for unknown reasons

D．You can hear other people’s phone conversations

小題3:What does the underlined sentence in the last paragraph mean?

A．Mobile phone producers have made no progress.

B．Mobile phone producers are proud of their products.

C．Mobile phone producers are faced with a difficult situation.

D．Mobile phone producers refused to fight against virus.

小題4:For whom is the passage written?

A．Government officials	B．Virus spreading experts
C．Electronic scientists	D．Mobile phone users

You never see them, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潛水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to（易遭受）impact – from its original position in the landing wells (起落架艙). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft.
Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1, 2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
小題1:What information could be found from the black box on the Yemeni airliner?

A．Data for analyzing the cause of the crash.

B．The total number of passengers on board.

C．The scene of the crash and extent of the damage.

D．Homing signals sent by the pilot before the crash.

小題2:Why was the black box redesigned in 1965?

A．New materials became available by that time.

B．Too much space was needed for its installation.

C．The early models often got damaged in the crash.

D．The early models didn't provide the needed data.

小題3:Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

A．To distinguish them from the colour of the plane.

B．To caution people to handle them with care.

C．To make them easily identifiable.

D．To obey international standards

小題4:What do we know about the black boxes from Air France Flight 447?

A．There is still a good chance of their being recovered.

B．There is an urgent need for them to be reconstructed.

C．They have stopped sending homing signals.

D．They were destroyed somewhere near Brazil.

It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.
The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centers are set up. In their study, the researchers examined groups of nine-month-old babies in new South Wales and Britain.
And they came across astonishing results—it was found that infants had “social brains” and focused not just on their mothers but on social 1ife in groups as well,
“They communicate with more than one baby at once，and show jealousy and generousness，”said Professor Bradley．
He added，“They develop their own meanings through group interaction，they notice if a group member is behaving differently and they take on roles，such as leaders and followers．”
“A baby who has a depressed mother tends to be withdrawn(內(nèi)向的)，but put that same baby in a group of its peers(同齡人)and they behave and interact like any other baby．”
It was the first all-baby group study ever to be conducted．“Most studies of babies concentrate on the infant-mother relationship，assuming that is the single foundation for mental health．but babies are constantly involved with groups of people other than their mothers：fathers，siblings，grandparents and those taking care．Therefore。the ‘mother-baby approach’ needs to be combined with a‘ group approach’．”said Bradley．
Phoebe Christison ，a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west．said she often noticed what appeared．to be emotional attachments developed between toddlers．
She said，“Joel(10 months)and Isabella (11months)always like to hold hands when they sit in their high chairs and eat．And babies definitely show jealousy．They push and touch each other，and copy what the other is doing．”
小題1:A baby who has a depressed mother ____  ．

A．tends to be a follower

B．a(chǎn)lso enjoys group interaction

C．has poor social ability

D．pays more attention to its mother

小題2:What can be inferred from the result of this study?

A．Babies are affected by groups more than by their mothers．

B．There’s no need of child-care centers at a11．

C． Adults should include babies when having social activities．

D．The normal infant-mother bond alone isn’t enough for the good mental health for babies．

小題3:The underlined word “toddlers” in Para．8 can be replaced by_________

A．a(chǎn)dults

B．infants

C．peers

D．groups

小題4:The example given in the last paragraph proves that a baby________ .
