Young people can have problems with their minds. Some students become worried because they have to study very hard. Others have trouble getting on well with people like their parents and classmates.
Liu Wei, a Junior 2 student from Hefei, could not understand his teacher and was doing badly in his lessons. He became so worried about it that he started to cut his finger with a knife. Another student, 14-year-old Yan Fang from Guangzhou, was afraid of exams. She got very worried in the test, and when she looked at the exam papers, she couldn’t think of anything to write.
A recent report from Jiefang Daily says about 18% of Shanghai teenagers have mental (精神上的，心理上的)problems. Their troubles include being worried and very unhappy, and having problems in learning and getting on well with people. Many students who have problems won’t go for advice or help. Some think they will look stupid if they go to see a doctor. Others don’t want to talk about their secret.
Liang Yuezhu, an expert on teenagers from Beijing Aiding Hospital has the following advice for teenagers.
1). Talk to your parents or teachers often.
2). Take part in group activities and play sports.
3). Go to see a doctor if you feel unhappy or unwell.

Nowadays, a cellphone service is available to everyone, everywhere. Probably thousands of people have already been using it, but I just discovered it, so I'm going to claim it and also name it: Fake Foning.
The technology has been working well for me at the office, but there are infinite(無限的） applications. Virtually in any public space.
Say you work at a big university with lots of talky faculty members buzzing about. Now, say you need to use the restroom. The trip down the hall will take approximately one hour, because a person can't walk into those talky people without getting pulled aside for a question, a bit of gossip, a new read on a certain line of Paradise Lost.
So, a cellphone. Any cellphone. Just pick it up. Don't dial. Just hold that phone to your face and start talking. Walk confidently down the hall engaged in fake conversation, making sure to tailor both the topic and content to the person standing before you whom you are trying to avoid.
For standard colleague avoidance, I suggest fake chatting about fake business:
"Yes, I'm glad you called, because we really need to hammer out the details. What's that? Yes, I read Page 12, but if you look at the bottom of 4, I think you can see the problem begins right there."
Be engaged in your fake fone conversation. Make eye contact with the people passing, nod to them, gesture keen interest in talking to them at a later time, point to your phone, shrug and move on.
Shoppers should consider fake foning anytime they spot a talky neighbor in the produce department pinching (用手捏) unripe peaches. Without your phone at your face, you'd be in for a 20-minute speech on how terrible the world is.
One important caution about fake foning. The other day I was fake foning my way past a colleague, and he was actually following me to get my attention. I knew he wanted to ask about a project I had not yet finished. I was trying to buy myself some time, so I continued fake foning with my doctor. "So I don't need the operation? Oh, doctor, that is the best news."
And then: Brrrrrrng! Brrrrrmg! Brrrrrmg! My phone started ringing, right there while it was planted on my face. My colleague looked at me, and I at him, and naturally I gasped. "What is the matter with this thing?" I said, pulling the phone away to look at it, and then putting it back to my ear.
"Hello? Are you still there?"  Oops.
【小題1】According to the passage Fake Foning is _______________________.

A．a(chǎn) strategy to avoid people	B．a(chǎn) device newly produced
C．a(chǎn) service provided everywhere	D．a(chǎn) skill of communication

【小題2】In the author's opinion, in order to make fake foning look real one has to__________________.

【小題3】What does the last example show?

A．One effective way is to fake fone one's doctor.

B．One has to be careful while fake foning.

C．Fake foning may not cheat people.

【小題4】After his phone suddenly began ringing, the author___________________.

A．immediately started talking to the caller

B．immediately started talking to his colleague

If there is one thing I’m quite sure about, it is that in a hundred years from now we still be reading newspapers. Not those newspapers are a necessity. Even now some people get most of the news from the television or have the radio switched on in the background or in the car. Many buy a paper only on Saturday or Sunday. But for most people a newspaper has become a habit passed down from generation to generation.
The basic British character won’t change, and one of the characteristics of the British is that we don’t much like talking to each other when we get up. So what better way is there to keep yourself thinking in the morning than to wrap yourself in a newspaper?
Over the past couple of centuries, human beings have developed a close relationship with the newspaper. It has become as natural as breathing or enjoying the sun. And it is not just the British who love newspapers. On suburban trains in Calcutta, for instance, just one person in the whole car will buy a newspaper and read aloud the best bits to his fellow passengers, much to everybody’s enjoyment.
The nature of what is news may change. What essentially (本質(zhì)上) makes news is what affects our lives and the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic engineering. In the future I think there will be more coverage of scientific explanations of why we feel as we do, whether it’s love or depression. We develop a better understanding of how the brain operates and what our feelings really are.
It’s quite possible that in the next century newspaper will be transmitted electronically from the national equivalents of Fleet Street (倫敦的艦隊(duì)街，以報(bào)館集中而著稱) and printed out in our own homes. In fact, I’m pretty sure that that is how it will happen in future. You’ll be probably selecting from a menu, making up your own bespoke newspaper by picking out the things you want to read and say. You might even have an intelligent screening device (裝置) to do the job for you.
I think people have got it wrong when they talk about the competition between the different media. They actually have a relationship, feeding off each other. It was once predicted that television would kill off newspapers, which hasn’t happened. What is read on the printed page is more enduring (持久的) than pictures on a flickering screen or sound lost in the sky. And as for the Internet, it’s never really satisfying to read something just on a screen.
【小題1】The author of the passage is most probably from _______________.

A．Russia

B．India

C．Britain

D．America

【小題2】According to the passage, the future of newspapers ____________.

A．will be mainly connected with scientific research

B．will report more important political activities

A．a(chǎn) newspaper which dares to report the truth

B．a(chǎn) newspaper edited to one’s own interest

C．a(chǎn) newspaper edited and published for the public

D．a(chǎn) newspaper which only covers the life of family members

【小題4】Which of the following is TRUE according to the passage?

A．It was centuries ago that newspapers came into being .

B．Televisions have taken the place of newspapers .

C．The Internet will gradually take the place of newspapers.

D．The nature of news may remain the same over generations.

As anyone who has tried to lose weight knows, realistic goal-setting generally produces the best results. That’s partly because most people who set realistic goals actually work more efficiently, and put more effort, to achieve those goals.
What’s far less understood by scientists, however, are the potentially harmful effects of goal-setting. Newspapers convey daily accounts of goal-setting widespread in industries and businesses up and down both Wall Street and Main Street, yet there has been surprisingly little research on how the long-advocated practice of setting goals may have contributed to the current economic crisis, and immoral behavior in general.
“Goals are widely used and promoted as having really beneficial effects. And yet, the same motivation that can push people to put more effort in a constructive way could also motivate people to be more likely to engage in immoral behaviors,” says Maurice Schweitzer, an associate professor at Penn’s Wharton School. His paper, titled “Goals Gone Wild: The Systematic Side Effects of Over-Praised Goal Setting,” appears in the February issue of the Academy of Management Perspectives.
“It turns out there’s no financial benefit to just having a goal---you just get a psychological benefit” Schweitzer says. “But in many cases, goals have financial rewards that make them more powerful.”
A major example Schweitzer and his colleagues give is the 2004 breakdown of energy-trading giant Enron( 德國安然公司), where managers used financial rewards to motivate salesmen to meet specific goals. The problem, Schweitzer says, is that the actual trades were not profitable. 
Other studies have shown that burdening employees with unrealistic goals can force them to lie, cheat or steal. Such was the case in the early 1990s when Sears（西爾斯公司）placed a sales quota (銷售限額) on its auto repair staff. It inspired employees to overcharge for work and to complete unnecessary repairs on a companywide basis.
Schweitzer admits his research runs counter to a very large body of literature that praises the many benefits of goal-setting. Advocates of the practice have argued with his team’s use of such evidence as news accounts to support his conclusion that goal-setting is widely over-praised.
In a rebuttal (反駁) paper, Dr. Edwin Locke writes: “Goal-setting is not going away. Organizations cannot grow without being focused on their desired end results any more than an individual can grow without goals to provide a sense of purpose.”
But Schweitzer argues the “evidence” linking goal-setting and harmful behavior should be studied to help draw attention to issues that deserve attention and further investigation. “Even a few negative effects could be so large that they outweigh many positive effects,” he says.
The debate is likely to get heated on in future papers, and the practice of setting goals no doubt will continue. For now, though, the lesson seems to be to put more thought into setting goals.
“Goal-setting does help motivate people. My idea would be to combine that with careful management, a strong organizational culture, and make sure the goals that you use are going to be constructive and not significantly harmful to the organization,” Schweitzer says.
【小題1】What does Maurice Schweitzer want to show by mentioning the example of Enron?

D．a(chǎn)pplies to

【小題4】What is Edwin Locke’s argument against Schweitzer?

A．The practice of setting goals only helps people to develop.

B．Goal-setting is of no use motivating people to accomplish their tasks.

C．The positive effects of goal-setting outweigh its negative effects.

D．Studying goal-setting can contribute to successful business practices.

【小題5】According to the passage, the author tries to convey ___________.

A．the goals that most people set are unrealistic.

B．a(chǎn)ll people can improve their work quality by setting goals.

C．setting goals can provide people with a sense of purpose.

D．people should not ignore the negative effects of goal-setting.

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (學(xué)術(shù)界) outweigh any financial considerations.
　　Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects(前景) of a commercial return, and Lee’s is one of them.
　　The impact of a salary cut is probably less serious for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制藥的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual(智力的) opportunities.
　　Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (轉(zhuǎn)換) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary(包括各種學(xué)科的) team, manage budgets and negotiate(談判) contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”
【小題1】By “a one-way street” in the first paragraph, the author means ________.

A．university researchers know little about the commercial world

B．there is little exchange between industry and academia

C．few industrial scientists would quit to work in a university

D．few university professors are willing to do industrial research

【小題2】The word “deterrent” most probably refers to something that _____.

A．keeps someone from taking action

B．helps to move the traffic

C．a(chǎn)ttracts people’s attention

D．brings someone a financial burden

【小題3】What was Helen Lee’s major consideration when she changed her job in the middle of her career?

A．Flexible work hours.

B．Her research interests.

C．Her preference for the lifestyle on campus.

D．Prospects of academic accomplishments.

【小題4】Guy Grant chose to work as a researcher at Cambridge in order to ________.

A．do financially more rewarding work

B．raise his status in the academic world

C．enrich his experience in medical research

D．have better intellectual opportunities

【小題5】What contribution can industrial scientists make when they come to teach in a university?

A．Increase its graduates’ competitiveness in the job market

B．Develop its students’ potential in research.

C．Help it to obtain financial support from industry.

D．Adapt its research to practical applications.

By the mid-nineteenth century, the “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families of their own use. This had become possible because a new household convenience, the icebox, a precursors of modern refrigerator, had been invented.
Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.
But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium(獎(jiǎng)金) price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.
【小題1】What does the passage mainly discuss?

A．The influence of ice on the diet.

B．The development of refrigeration.

C．The transportation of goods to market.

D．Sources of ice in the nineteenth century.

【小題2】According to the passage, when did the word “icebox” become part of the language of the United States?

A．in 1803	B．sometime bore 1850
C．during the civil war	D．near the end of the nineteenth century.

【小題3】The phrase “forward-looking” in line 3 is closest in meaning to______.

A．progressive

B．popular

C．thrifty

D．well-established

【小題4】The author mentions “fish” in the passage because _____.

A．many fish dealers also sold ice.

B．fish was shipped in refrigerated freight cars.

C．fish dealers were among the early commercial users of ice

D．fish was not part of the ordinary person’s diet before the invention of the icebox.

When I was 13, my bedroom walls were covered with posters of the Monkees and Beatles. I wrote fan letters and daydreamed about meeting the objects of my affections. I begged my  parents to attend every rock concert and watch every TV show featuring my favorite celebrities; my friends and I discussed for hours all the things we would say and do when we met our favourite movie stars and pop singers. I drove my mother crazy ! But after a few years, my obsession stars faded as I matured and gained the confidence to socialize with “real” boys.
In the 35 years since I was a teenager, celebrity worship (崇拜) has increased among teens due to the explosion of television celebrity gossip shows, and instant access to celebrity news on the Internet. It’s no wonder that many teens are obsessed with stars when news programs are often filled with entertainment stories and the lives of celebrities.
Celebrity worship syndrome (綜合征) is now considered a personality disorder. While it is normal for teenagers to follow the lives of their favorite stars, parents should try to monitor everything their child finds interesting. Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family.  When teens talk a lot about celebrities and view them as just means of entertainment, this is considered normal celebrity worship. However, when a teenager is obsessed with a star and  often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star, this may be the time for concern. Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low self confidence and depression. Teens who are overly obsessed with stars often have damaged relationships with their parents.
【小題1】The first paragraph is intended to tell us________.

A．parents needn’t worry about celebrity worship

B．celebrity worship can cause serious problems

C．it’s normal for a teen to have celebrity worship

D．celebrity worship only exists among teens

【小題2】We can learn from the second paragraph that________.

A．the media greatly contributes to celebrity worship today

B．the author is surprised at celebrity worship

C．teens today are not so obsessed with celebrities

D．celebrities expose their lives too much

【小題3】Parents should become concerned when their children________.

A．talk a lot about celebrities with others

B．put up celebrity posters in their bedrooms

C．a(chǎn)sk to go to their favourite star’s concert

D．desire a close personal relationship with their favorite star

【小題4】The last paragraph implies that________.

A．parents should not care too much about a child’s celebrity worship

B．celebrity worship syndrome can be a serious problem if left overlooked

C．children can normally get out of celebrity worship when they are older

D．children with celebrity worship usually have high opinion of themselves

【小題5】What is most likely to be talked about in the paragraph following the passage?

A．The harm of celebrity worship syndrome.

B．More signs of celebrity worship syndrome.

C．What to do with children’s celebrity worship syndrome.

D．Who will suffer most from celebrity worship syndrome.

There is a famous story about British poet Samuel Taylor Coleridge. He was writing a poem when he was interrupted by a knock at the door.
This was an age before telephones. Someone was delivering a message. When Coleridge got back to his poem, he had lost his inspiration. His poetic mood had been broken by the knock on his door. His unfinished poem, which could otherwise have been a masterpiece, would now never be more than a fragment.
This story tells how unexpected communication can destroy an important thought, which bring us to the cellphone.
The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.
We have already entered a golden age of little white lies about our cellphones, and this is by and large（大體上）a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.
The notion of being unreachable is not a new concept—we have “Do Not Disturb” sign on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?
Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees（信徒）, myself usually included, can’t help at times wanting to throw their phone away, or curse the day they were invented.
But we don’t and won’t, and there really is no need. All that’s required to take back our private time is a general social recognition that we have the right to it. In other words, we have to develop a healthy contempt(輕視) for the rings of our own phones.
A cellphone call deserves no greater priority(優(yōu)先考慮的事) than a random(隨機(jī)的) word from the person next to us，though the call on my cellphone may be the one-in-a-million from Steven Spielberg—who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.
【小題1】What is the point of the anecdote about the poet Coleridge in the first three paragraphs?

A．To direct readers’ attention to the main topic.

B．To show how important inspiration is to a poet

C．To emphasize the disadvantage of not having a cellphone

D．To encourage readers to read the works of this poet.

【小題2】What does the writer think about people telling “white lies” about their cellphones?

A．It is a way of signaling that you don’t like the caller.

B．It is natural to tell lies about small things

C．It is basically a good way to protect one’s privacy.

D．We should feel guilty when we can’t tell the truth.

【小題3】According to the author, what is the most annoying problem caused by cellphones?

A．People get so obsessed(著迷) with the cellphone rings that they fail to notice anything else.

B．People feel guilty when they are not able to answer their cellphones.

C．Cellphones interrupt people’s private time.

D．With cellphones it is no longer possible to be unreachable.

【小題4】What does the last paragraph suggest?

A．A person who calls us from afar deserves more of our attention

B．Steven Spielberg once called the author to talk about the author’s novel.

C．You should always finish your lunch before you answer a call on the cellphone.

D．Never let cellphones disturb your life too much.

Internet has become part of young people’s life. You can do lots of things on line such as chatting, sending messages and emails, getting useful knowledge and information, buying things without going to the shops, visiting cool websites, and so on. But it’s also easy to be cheated online. Here’s a story about a girl named Mary.
Mary is an 18-year-old girl who lives in New York. The people in Mary’s family are so busy that they hardly have time to be with her. In fact, Mary is quite lonely. So she spends a lot of time on QQ.
Last year Mary made a very special friend on QQ. His name was David and he lived in San Francisco. David was full of stories and jokes. He and Mary had a common interest in rock music and modern dance. So it always took them hours to talk happily on QQ and sometimes they even forgot the time. David sent Mary a picture of “himself”: he was a tall, good-looking young man with a big, happy smile. As time went by, they became good friends and often sent cards and small things to each other.
Before David’s birthday, Mary wanted to give him a surprise. She flew to San Francisco. But when Mary knocked on David’s door, she found that the special friend was a twelve-year-old boy named Jim!
So when you make friends on the Internet, please be careful. Here are some rules to make sure you are safe and have fun on the Internet.
u    Don’t give your password to anyone else, and never let out the following information: your real name, home address, age, school, phone number or other personal information.
u    Never agree to meet someone you met on the Internet without your parents’ permission. Never meet anyone you met online alone.
