A Good Friend, A Second Self

I couldn’t believe my ears when I heard my name called for the leading role in our high school play. Mrs. Dermitt, my drama teacher, had been looking for someone to play an energetic boy in a comedy. Luckily for me, she thought that I could handle the   36  .

That afternoon my friend Kevin and I talked   37   about the play. Although Kevin hadn’t been   38   for a part onstage, his job with the set crew was important to the success of the play. I told him I was a little   39   because I had a lot of lines to memorize.

“You can do it.” He said. I knew I could   40   him: we had been friends since the third grade, and we   41   a good team.

Preparations for the play moved at a rapid pace. While working hard with the set crew, Kevin   42   spent hours helping me learn my lines. He often said my lines with me by silently moving his lips. We   43   that he could probably play my part as well as I could.

Three days before the   44   night, everything was ready for the performance. But when I woke up   45   a fever and sore throat on the day of the play, the entire production came to a sudden   46  . Everyone in the drama department was worried,   47   there was no way I could perform. The play was   48   to open in fewer than six hours, and we had no time to cancel.

While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.

The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to compete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.

I watched the man dive off the block and knew right away that something was wrong. I’m not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold ? his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.

I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.

But in those few awful strokes, the crowd had changed.

No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.

A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and he should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.

Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.

In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.

59.From the passage we can learn that the young man         .

      A.made his turn to start back pitifully

       B.was skillful in freestyle in the game

       C.swam faster than the average swimmer

       D.was not capable enough to win the medal

60.The crowd changed their attitudes because          .

       A.they felt sorry for the young man

       B.they were moved by the young man

       C.they wanted to show their sympathy

       D.they meant to please the young man

61.According to the passage, “it is nice to watch an underdog” probably means         .

       A.it’s amusing to watch a man with awful swimming skills

       B.it’s amazing to watch an ordinary man challenging himself

       C.it’s cheerful for athletes to act proudly before their competitors

       D.it’s brave enough for some athletes to remove the silver medals

62.What’s the best title for the passage?

       A.Compete for Gold!                         B.Try again!

       C.Break a Record!                                                             D.Go for it!

In Alexandria, Virginia, the two thousand students at T. C. Williams High School started classes last month in a new building. It was built as a “green” school based on requirements from the United States Green Building Council.

The council is a nonprofit organization made up of building industry leaders. It has a rating system for buildings called Leadership in Energy and Environmental Design, or LEED.

In 2001, there were four schools asking for LEED certification. Now there are four hundred, including T.C. Williams. So far, fifty-eight schools have been recognized for meeting the requirements. These include protecting natural areas and limiting the amount of chemicals in building materials. They also include better lighting and improved indoor air quality. Buildings are also rated on how well they use energy and water, and on things like the use of recycling programs. At T.C. Williams, one example of green design can be seen in the many windows that let in natural light. Students say the sunny rooms help them stay awake during class.

A rooftop garden is designed to provide storm water control and help keep the building cool in the sun. And an underground tank can store 1,700,000 liters of rainwater for air conditioning and other systems.

The new building cost about 90,000,000 dollars to build. It stands next to the old T.C. Williams building, which officials say will slowly be taken apart and recycled. T.C. Williams High School is still waiting for the final part of the LEED certification process. Schools receive points for the number of requirements they meet. Buildings are rated silver, gold or platinum.

Around the country, concerns about limited budgets for public schools sometimes lead to objections to investing in “green” schools. But the Green Building Council points to a report by Capital E, a Washington, D.C., company that serves the clean energy industry. Capital E examined the cost of thirty “green” schools in the United States. It says the average cost was only two percent higher compared to a traditional school. And it says this extra cost is small compared to the savings over time from lower energy and water costs and healthier students.

63.The United States Green Building Council aims to         .

      A.collect money for “green” schools

       B.construct “green” buildings on its own

       C.promote the construction of “green” schools

       D.evaluate the “greenness” of any school building

64.We know from the passage that         .

       A.LEED evaluates the buildings at four different levels

       B.Capital E designed many requirements for “green” schools

       C.T.C. Williams High School has received LEED certification

       D.LEED is provided by the United States Green Building Council 

65.The underlined word they in Paragraph 3 refers to          .

       A.the requirements                                                           B.the natural areas

       C.the building materials                    D.the amount of chemicals

66.What can be inferred from the last paragraph?

       A.Green schools cost more than traditional ones.

       B.Capital E is devoted to the clean green industry.

       C.Green schools will have more benefits in the long term.

       D.Limited budgets cause a disagreement on “green” schools.

jobs, Jonathan Grubin, a 16 ? year ? old boy, has logged on to an

online success which turned over £75,000 last year.

Now his success is already beginning to show with the launch

of ForFrea4U.co.uk, which offers visitors free iPods and digital

cameras for signing up their friends to its advertisers. Jonathan has

got more than 55,000 members to the site in less than two years,

sending off £25,000 worth of products.

His success is down to a business move known as affiliate marketing, a web ? based marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate’s marketing efforts.

The Royal Grammar School student said: “I have always been interested in websites and the ideas behind them. I though, ‘if only there was another way I could get my hands on these goods’, so I made a website for a bit of fun.” Jonathan added: “I partner with some advertisers, and they send me commission (傭金) each time I get them a new customer. I offer visitors to my website a reward when they sign up.”

“Advertisers were very quick to realize the potential of the network. Affiliale marketing is highly successful for advertisers because they only pay when they see results.”

“When you run an expensive television advertising campaign, nothing is guaranteed. But with my business model, advertises only pay their commission when they see results.”

Jonathan, who works from his computer at home, launched his first website when he was 12 offering mobile phone wallpapers and screensavers after rival sites were charging youngsters for downloads.

He also runs livenewcastle. co. uk, a resource website for Newcastle with listings, reviews and directories. He added: “I remember receiving my first cheque, it was £10.44, and I was amazed that I had received it. The only thing I really want to do is to be able to work for myself.”

“There are a lot of downsides, but there are advantages too. The fact is that I am so young, and when I’m 20, I’m going to have a lot of knowledge and experience that most people won’t have until they are 30 or 40.”

67.Which of the following helps lead to the success of For Free4U.co.uk?

       A.It provides visitors with presents for signing up their friends to its advertisers.

       B.It offers teenagers mobile phone wallpapers and screensavers for free.

       C.It gets payment when it publishes ads.

       D.It charges youngsters for downloads.

68.Which of the following is NOT true according to the passage?

       A.Jonathan set up his first website when he was twelve.

       B.Jonathan is a student of Royal Grammar School.

       C.Jonathan founded the websites for money only.

       D.Jonathan is in charge of two websites now.

69.According to the passage, it’s obvious that        .

       A.Jonathan’s websites are popular with both visitors and advertisers

       B.visitors sign up on Jonathan’s website in order to get rewards

       C.a(chǎn)dvertisers pay for their products being advertised online

       D.Jonathan is interested in working all by himself

70.The passage is mainly about          .

       A.a(chǎn) smart online advertising technique

       B.a(chǎn) promising business web - master

       C.a(chǎn) web ? based marketing producer

       D.a(chǎn) successful online marketing

Today’s career assumptions are that you can get a lot of development, challenge and job satisfaction and not necessarily be in a management role.

“I hated all the meetings,” says a 10-year award-winning manager, “And I found the more you did for people who worked for you, the more they expected.”

  Managing others is always a tough task, but in the past that stress was balanced by hopes for career mobility and financial rewards. Along with a sizable pay raise, people chosen as managers would begin a nearly automatic climb up the career ladder to lucrative executive private benefits: company cars, club memberships, plus the key to the executive washroom.

But in today’s global, more competitive showground, a manager sits in an insecure chair.  Restructuring has removed layer after layer of management as companies came to view their organizations as collections of talents rather than hierarchies(等級). There are far fewer steps for managers to climb. Also, managerial jobs demand more hours and headaches than ever before but offer slim, if any, financial paybacks and perks.

Now managers must manage many people who are spread over different locations, even over different continents. They must manage across functions with, say, design, finance and marketing.

In an age of entrepreneurship, when the most praised people in business are those launching something new, management seems like an invisible, thankless role. Employers are looking for people who can do things, not for people who make other people do things.

In addition, the Dilbert factor is at work. With Dilbert’s popular cartoon character as well as many television situation comedies routinely describing managers as fools or enemies, they just don’t get much respect any more.

  Moreover, it may not pay to be a manager at least not the way it once did. Ms. Chmielewski says. “The emotional rewards can be great, and there were times I enjoyed management. But a 10-to-11-hour day and one weekend day a month is the norm.”

  With more people cautious of joining management, are corporations being hurt or worrying about developing future leaders? Not many are. While employers have dismissed a lot of managers, they believe many more candidates lingers on at many companies. “Another reason companies aren’t short of managers”, argues Robert Kelly, a business professor, “is that so many workers today are self-managed, either individually or via teams, you don’t need a manager.”

71.By writing the passage, the writer seems to         .

       A.explain reasons for firing managers

       B.a(chǎn)dvise people not to become managers

      • 穗下第一張葉片(旗葉)的光合作用

        供給,其它綠色部分如麥穗也有光合能

        力。圖17示小麥旗葉和麥穗光合作用

        與耐旱性關(guān)系的研究結(jié)果。請回答下

        列有關(guān)問題:

           (1)由圖可知,          的興合作用

        對缺水比較敏感,如果小麥在孕穗

        期和開花期遇到干旱,將對產(chǎn)量有

        較大的影響。同時,        的光合作用對干旱有較強(qiáng)的適應(yīng)性,這對植物度過不良環(huán)境有一定的積極作用。

           (2)水分對光合作用的影響是多方面的。一方面缺水可導(dǎo)致氣孔關(guān)閉,光合作用會因

                             階段的原料不足而受到影響。另一方面缺水還會使物質(zhì)運(yùn)輸變慢,當(dāng)光合產(chǎn)物在        中積累過多時,會使光合作用產(chǎn)生反饋性抑制。

           (3)不同程度的缺水對光合作用的影響也有所不同。中度缺水會影響葉綠體囊狀結(jié)構(gòu)薄膜上的電子傳遞,從而使           的形成受到抑制;嚴(yán)重缺水還會造成葉綠體囊狀結(jié)構(gòu)的破壞,而且在供水后也難以恢復(fù)。因而,植物不能長時間缺水,合理灌溉就是指根據(jù)植物的需水規(guī)律              地進(jìn)行灌溉。

        30.(18分)請回答下列有關(guān)溫度與酶活性的問題:

           (1)溫度對唾液淀粉酶活性影響的實(shí)驗(yàn):

                將盛有2mL唾液淀粉酶溶液的試管和盛有2mL可溶性淀粉溶液的試管編為一組,共四組。在0℃、20℃、37℃和100℃水浴中各放入一組,維持各自的溫度5min。然后,將淀粉酶溶液注入相同溫度下的淀粉溶液中,搖勻后繼續(xù)放回原來的溫度下保溫。

                把                               的時間作為本實(shí)驗(yàn)的起始時間記錄下來。再每隔一分鐘,取一滴混合液滴在盛有碘液的點(diǎn)滴板上進(jìn)行觀察,記錄每種混合液藍(lán)色消失的時間。通過比較混合液中         消失所需時間的長短來推知酶的活性。預(yù)計          溫度下混合液因其中的酶失去活性藍(lán)色不會消失。

           (2)溫度對酶活性的影響主要體現(xiàn)在兩個方面。其一,隨溫度的升高會使         接觸的機(jī)會增多,反應(yīng)速率變快。其二,因?yàn)榇蠖鄶?shù)酶是蛋白質(zhì),本身隨溫度升高而發(fā)生            的改變,溫度升到一定程度,酶將完全失活。這兩種作用疊加在一起,使酶促反應(yīng)在某一溫度下最快,這一溫度就是該酶的                

           (3)科研人員通過蛋白質(zhì)工程來設(shè)計改變酶的構(gòu)象。在研究溶菌酶的過程中,得到了多種突變酶,測得酶50%發(fā)生變性時的溫度(Tm),部分結(jié)果見下表:

      • 16號染色體上,胎兒期和成年期基因的表達(dá)情況

           (1)人在不同發(fā)育時期血蛋白的組成不同,這是

        紅細(xì)胞不同基因                 的結(jié)果。

        圖中α鏈由141個氨基酸組成,β鏈由146

        個氨基酸組成,那么成年人血紅蛋白分子的

        肽鍵數(shù)是              

           (2)圖中11號染色體上β珠蛋白基因中一個堿

        基對的改變,導(dǎo)致谷氨酸被纈氨本替換(人

        類鐮刀型細(xì)胞貧血癥)。已知谷氨酸被纈氨酸的密碼子之一為GAA,纈氨酸的密碼子之一為GUA。則突變后的基因控制該氨基酸的相應(yīng)片段其堿基組成是                      

           (3)下列哪種方法不能用來確診鐮刀型貧血癥的患者(單選)

        C.檢測血紅蛋白的氨基酸序列    

        D.利用基因探針進(jìn)行分子雜交

           (4)圖19是一個鐮刀型細(xì)胞貧血癥的系譜圖。由此

        可知,鐮刀型細(xì)胞貧血癥是           遺傳病。

        原因(基因用B、b表示)。

           (5)一位研究者檢驗(yàn)了東非某人群中290人兒童的血樣。

        在這個人群中瘧疾和鐮刀型貧血癥都流行,調(diào)查結(jié)果見下表:

        In Glasgow, Scotland, a young lady, like a lot of teens today, got tired of home. The daughter objected to her family’s   41   lifestyle and said, “I don’t want your God. I am leaving!”

        She left home. Before long, she was disappointed and unable to find a job, so she took to the streets to do everything she could to   42  . Many years passed by, her father died, her mother grew   43  , and the daughter became more and more entrenched (固執(zhí)) in her way of life.

        No contact was made between mother and daughter during these years. The mother, having   44   her daughter’s whereabouts, went to the poor part of the city in   45   of her daughter. She stopped at each of the rescue missions (收容所) with a simple   46  . “Would you allow me to   47   this picture?” It was a picture of the smiling, gray-haired mother with a handwritten   48   at the bottom: “I love you still … come home!”

        One day the daughter wandered into a rescue mission for a hot meal. She sat   49   listening to the service, all the while letting her   50   wander over to the bulletin board. There she saw the picture and thought, could that be my mother?

        She couldn’t   51   until the service was over. She stood and went to look. It was her mother, and there were those words, “I love you still … come home!”  52   she stood in front of the picture, she wept. It was too   53   to be true.

        It was night, but she was so   54   by the message that she started walking home.  55   the time she arrived it was early in the morning. She was afraid and   56   her way timidly (膽怯地). As she knocked, the door   57   open on its own. She thought someone must have broken into the house.

        第三部分:閱讀理解(共20小題;每小題2分,共40分)

        A

        Are you too old for fairy tales? If you think so, Copenhagen is sure to change your mind. See the city first from the water. In the harbor sits Denmark’s best-known landmark: the Little Mermaid. Remember her? She left the world of the sea people in search of becoming a human in one of Hans Christian Andersen’s beloved fantasies. From the harbor you can feel “city of green spires (尖頂)”. At dawn or on a cloudy day, the copper-covered spires of old castles and churches give the city a dream-like atmosphere. You’ll think that you’ve stepped into a watercolour painting.

        Copenhagen is a city made for people. You don’t have to hurry to walk through the city’s center in less than an hour. Exploring it will take much longer, but that’s easy. Copenhagen is the first city to make a street for walking only. The city has less traffic, noise, and pollution than any other European capital.

        Churches and castles are almost all remains of the original city. Copenhagen became the capital of Denmark in 1445. During the late 16th century, trade grew, and so did the city. But fires in 1728 and 1795 destroyed the old wooden buildings. Much of what we see today is from the 19th and early 20th centuries.

        Look at one of the spires up close ― really close ― at the 17th-century Church of Our Savior. Brave people may climb the 150 stairs winding outside the spire to its top. If you are afraid of heights, or if it’s a windy day, you can forget about the climb. But then you’ll miss the beautiful view.

        To see people having fun, and to have some fun yourself, cross Andersens Boulevard and enter Tivoli Gardens. You won’t be alone. More than five million people a year come here. They come to dance, eat, listen to outdoor and indoor concerts, watch ballets and laugh during comedy shows. One tip: Bring a lot of money. About 20 restaurants are among the city’s most expensive. Even without money, though, you can still enjoy the proud old trees, the coloured night lights and the beautiful gardens. You might feel as if you were in a fairy tale.

        61. Why is Copenhagen sure to change your mind ― that you are too old for fairy tales? Because ______.

        A. the Little Mermaid is Denmark’s best-known landmark

        B. Copenhagen is a city of green spires and wooden buildings that often appears in fairy tales

        C. Copenhagen is like a dream-like watercolour painting

        D. Copenhagen is a city where you find yourself in a fairy atmosphere

        62. What do you think of the city?

        A. A small quiet city which few city travelers visit.

        B. An international trade port which is busy.

        C. A beautiful ancient city with many travelers.

        D. A city where some fairy stories happened.

        63. Which of the following statements is NOT true?

        A. Mermaid is a character in one of Hans Christian Andersen’s fantasies.

        B. The 17th-century Church of Our Savior is high.

        C. Mermaid is a heroine in Denmark.

        D. Copenhagen has less traffic, noise and pollution in Europe.

        64. Which title is the most suitable for the passage?

           A. The imaginary fairy city ― Copenhagen

        B. Not only ancient but modern ― Copenhagen

        C. City of green spires ― Copenhagen

        D. A fairyland ― Copenhagen

         

        B

        The U.S.Department of Labor statistics (統(tǒng)計) show that there is an oversupply of college trained workers and that this oversupply is increasing. Already there have been more than enough teachers, engineers, physicists, aerospace experts, and other specialists. Yet colleges and graduate schools continue every year to turn out highly trained people to compete for jobs that aren’t there. The result is that graduates cannot enter the professions for which they were trained and must take temporary jobs which do not require a college degree.

        On the other hand, there is a great need for skilled workers of all sorts: carpenters, electricians, mechanics, plumbers, TV repairmen.

        These people have more work than they can deal with, and their annual incomes are often higher than those of college graduates. The old gap that white-collar workers make a better living than blue collar workers no longer holds true. The law of supply and demand now favors the skilled workmen.

        The reason for this situation is the traditional myth that college degree is a passport to a prosperous future. A large part of American society matches success in life equally with a college degree. Parents begin indoctrinating (灌輸) their children with this myth before they are out of grade school. High school teachers play their part by acting as if high school education were a preparation for college rather than for life. Under this pressure the kids fall in line. Whether they want to go to college or not doesn’t matter. Everybody should go to college, so of course they must go. And every year college enrollments (入學(xué)) go up and up, and more and more graduates are overeducated for the kinds of jobs available to them …

        One result of this emphasis on a college education is that many people go to college who do not belong there. Of the sixty percent of high school graduates who enter college, half of them do not graduate with their class. Many of them drop out within the first year. Some struggle on for two or three years and then give up.

        65. It’s implied but not stated in the passage that __________.

           A. many other countries are facing the same problem

        B. white-collar workers in the US used to make more money than blue-collar workers

        C. fewer students will prefer to go to college in the future

        D. the law of supply and demand has a strong effect on American higher education

        66. Which of the following is NOT a reason why college enrollments go up every year?

           A. Many people believe that the only way to success is a college education.

           B. Many parents want their children to go to college.

           C. High school teachers urge their students to go to college.

           D. Every young man and woman wants to go to college.

        67. By saying that “many people go to college who do not belong there,” the author means that ___.

           A. many people who are not fit for college education go to college

           B. many people who do not have enough money go to college

           C. many people who go to college drop out within the first year

           D. many people who go to college have their hopes destroyed

        68. We can infer from the passage that the author believes that ________.

           A. every young man and woman should go to college

           B. college education is a bad thing

           C. people with a college education should receive higher pay

           D. fewer people should go to college while more should be trained for skilled jobs

         

        C

        My new home was a long way from the centre of London but it was becoming essential to find a job, so finally I spent a whole morning getting to town and putting my name down to be considered by London Transport for a job on the tube. They were looking for guards, not drivers. This suited me. I couldn’t drive a car but thought that I could probably guard a train, and perhaps continue to write my poems between stations. The writers Keats and Chekhov had been doctors. T.S. Eliot had worked in a bank and Wallace Stevens for an insurance company. I would be a tube guard. I could see myself being cheerful, useful, a good man in a crisis. Obviously I would be overqualified but I was willing to forget about that in return for a steady income and travel privileges ― those being particularly welcome to someone living a long way from the city centre.

        The next day I sat down, with almost a hundred other candidates, for the intelligence test. I must have done all right because after half an hour’s wait I was sent into another room for a psychological test. This time there were only about fifty candidates. The examiner sat at a desk. You were signaled forward to occupy the seat opposite him when the previous occupant had been dismissed, after a greater or shorter time. Obviously the long interviews were the more successful ones. Some of the interviews were as short as five minutes. Mine was the only one that lasted a minute and a half.

        I can remember the questions now: “Why did you leave your last job?” “Why did you leave your job before that?” “And the one before that?” I can’t recall my answers, except that they were short at first and grew progressively shorter. His closing statement, I thought, revealed (顯露) a lack of sensitivity which helped to explain why as a psychologist, he had risen no higher than the underground railway. “You have failed the psychological test and we are unable to offer you a position.”

        Failing to get that job was my low point. Or so I thought, believing that the work was easy. Actually, such jobs ― being a postman is another one I still desire ― demand exactly the sort of elementary yet responsible awareness that the habitual dreamer is least qualified to give. But I was still far short of full self-understanding. I was also short of cash.

        69.The writer applied for the job because __________.

        A.he wanted to work in the centre of London

        B.he could no longer afford to live without one

        C.he was not interested in any other available job

        D.he had received suitable training

        70.The writer thought he was overqualified for the job because _________.

        A.he often traveled underground                 B.he had written many poems

        C.he could deal with difficult situations D.he had worked in an insurance company

        71.The length of his interview meant that _________.

        A.he was too nervous                              B.he had not done well in the intelligence test

        C.he did not like the examiner               D.he had little work experience to talk about

        72.What does the writer realize now that he did not realize then?

        A.How unpleasant ordinary jobs can be.    B.How difficult it can be to get a job.

        C.How unsuitable he was for the job.           D.How badly he did in the interview.

         

        D

        Sometime in the next century, the familiar early-morning newspaper on the front door will disappear. And instead of reading your newspaper, it will read to you. You’ll get up and turn on the computer newspaper just like switching on the TV. An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You’ll even get to choose the kind of voice you want to hear. Want more information on the brief story? A simple touch makes the entire text appear. Save it in your own personal computer file you like. These are among the predictions from communications experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers would unite print and broadcast reporting, offering news and analysis with video images of news events.

        Most of the technology is available now, but convincing more people that they don’t need paper to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. “ Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry.” Technology is making the end of traditional newspapers unavoidable.

           Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 to 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry.

        73.The best title for this passage is ______ .

        A.Computer Newspapers Are Well Liked

        B.Newspapers of the Future Will Likely Be on Computer

        C.Newspapers Are out of Fashion

        D.New Communications Technology

        74.It might take 30 to 40 years for computer newspapers to replace traditional newspapers, because _____.

        A.it is technologically impossible now

        B.computer newspapers are too expensive

        C.there is strong resistance from both the general population and professional journalists

        D.You can easily save information for future use

        75.Journalists are not eager to accept computer newspapers, because ________.

        A.they don’t know how to use computers

        B.they think computer newspapers take too much time to read

        C.they think the new technology is bad

        D.they have been trained to write for traditional newspaper

        76.We can infer from the passage that _______.

        A.a(chǎn)ll technological changes are good

        B.a(chǎn)ll technologies will eventually replace old ones

        C.new technologies will eventually replace old ones

        D.traditional newspapers are here to stay for another century

        I’m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today’s children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 yeas ago.

        Why are America’s kids so stressed? The report cites two main causes: increasing physical isolation (隔離) brought on by high divorce rates and less involvement in community, among other things and a growing perception that the world is a more dangerous place.

        Considering that we can’t turn the clock back, adults can still do plenty to help the next generation cope (應(yīng)付).

        At the top of the list is nurturing (培養(yǎng)) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties help build communities and protect individuals against stress.

        To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.

        Limit the amount of virtual violence your children are exposed to. It’s not just from video games and movies; children see a lot of murder and crime on the local news.

        Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.

        Make exercise part of your daily routine. It will help you cope with your own anxiety and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn’t have to ruin your life.

        77. The author thinks that the conclusions of any research about people’s state of mind are _______.

           A. surprising                 B. confusing               C. illogical                 D. questionable

        78. What does the author mean by saying “we can’t turn the clock back” (Para 3)?

        A. It’s impossible to slow down the pace of change.

        B. The social reality children are facing cannot be changed.

        C. Lessons learned from the past should not be forgotten.

        D. It’s impossible to forget the past.

        79. According to the analysis, compared with normal children today, children treated as mentally ill 50 years ago ________.

        A. probably suffered less from anxiety               B. were probably less self-centered

        C. were considered isolated physically                    D. were considered less individualistic

        80. The first and most important thing parents should do to help their children is ________.

        A. to provide them with a safer environment          B. to lower their expectations for them

        C. to get them more involved socially               D. to set a good model for them to follow
