You are going to read a magazine article in which a teenager discusses classical music. For questions, choose the answer (A, B, C or D) which you think fits best according to the text.Teenagers and Classical MusicWhen you see a teenager with an MP3 player, you can be pretty certain it's not classical music they're listening to. Most of us can list the names of dozens of pop groups, but ask any of my friends if they know who Brahms was and you can tell by the expression on their face that they haven't a clue. I have just started doing a music degree, but the people on my course know no more about the works of great composers than anyone else our age. And if you don't know who wrote the music, you are unlikely to go out and buy any recordings of their work.The statistics must be depressing for a lover of classical music. Apparently only 3% of concert tickets sold last year were for classical music events, and the average classical recording sells a mere 300 copies. I must say I still find that hard to believe. So what has caused this decline in interest for a type of music that has lasted for centuries? The older generation are irritated by our obsession with TV and video games, blaming it for most things, but I don't think there is any connection in this case. The simple truth is that classical music just doesn't hold much attraction for most people, and that is particularly true of teenagers, who are the ones most likely to buy music and concert tickets.Now I'm aware that this doesn't apply to everyone my age. I know some teenagers who go to classical music concerts all the time, but they are a minority. Although I am a musician and play in an orchestra, I'm not exactly a classical music fan. I enjoy a huge range of styles, but judging by what's stored on my computer, my classical music consumption is probably pretty close to that 3% figure.So why don't teenagers like classical music? Well, first of all, the pace and rhythm of classical music, with its numerous changes of mood, are problematic for us. We like to talk fast, play fast, and think fast. In addition, if you believe the experts, we have difficulty paying attention for more than about three minutes; far too short for most pieces of classical music, but perfect for a pop song. Pop is structurally quite simple and therefore easy to listen to, while appreciating a piece of classical music requires time and concentration. The subject matter of pop music also holds much more appeal than a lengthy piece of classical music with no lyrics. Classical music is incredibly powerful, but not full l of the issues that concern teenagers.The way we listen to music has also changed. In the past, families would gather at home to make music together, and an ability to play an instrument was highly valued. The only other opportunity to hear music was at a concert. Nowadays, you can find any music you want at the click of a mouse, and yet the sound track to our lives is rarely classical. When did you last go into a shop that had classical music playing in the background? In my orchestra we play classical music in all sorts of different places, but no matter how cool the posters are, I see virtually nothing but grey hair when l look into the crowd. Some say that the lack of interest in classical music among teenagers is the fault of our schools, but there are plenty of kids eager to play classical music in their school orchestra. They arrive early to practise and stay after school to rehearse. Classical music appeals to them when they perform, but otherwise it is not their music of choice. The two activities have become separated. When we want to relax, it's always pop music.(1)In the first paragraph, what does the writer say about teenagers? A.Their knowledge of classical music is limited to the names of composers.B.They don't listen to classical music because they don't know what to buy.C.Even the ones who study music have limited knowledge of classical music.D.Some would be embarrassed to admit to having classical music on their MP3 player.(2)How does the writer feel about the statistics she mentions in the second paragraph? A.disappointed that people are losing interest in classical musicB.annoyed that older people criticise the things that she enjoysC.surprised that so few people buy classical music recordingsD.certain that the future of classical music depends on teenagers(3)What is the meaning of the underlined phrase 'classical music consumption'? A.the amount of music she listens toB.the amount of music she playsC.the number of concerts she attendsD.the number of recordings she has made(4)The writer believes that teenagers prefer pop music becauseA.the style of it is always changing.B.the words used in it are relevant to their lives.C.it suits their many changes of mood.D.listening to it helps them to focus.(5)In the fifth paragraph, what does the writer say about classical music? A.We only really enjoyed it at concerts.B.We don't notice it being played.C.We should appreciate the way it is played.D.We hear it less than other kinds of music.(6)What is the writer's main point in the last paragraph? A.Pop music is generally more relaxing to listen to than classical music.B.Those who play classical music often don't like listening to it.C.Good classical musicians usually have to spend a lot of time practising.D.Schools are to blame if teenagers are not interested in classical music..

16．California has a new program called the Digital Textbook Initiative．"Starting this fall with high school math and science，we will be the first state in the nation to provide schools with a state-approved list of digital textbooks．"That was Governor Arnold Schwarzenegger in June，talking about his effort to get schools to use materials available free online．He listed reasons why he thinks digital textbooks make sense．California approves traditional textbooks in six-year cycles．Digital ones can offer the latest information．They lighten the load of school bags．They save paper and trees，and make learning more fun and interactive．And above all，he said，they help schools with their finances．The state has had to make severe cuts in school spending because of deep financial problems．More than six million students attend California public schools．Earlier this year，California invited content developers to offer digital math and science materials for high schools．These had to meet at least 90% of the state's learning requirements．Specially trained teachers examined 16 textbooks and approved ten of them．Six of the ten were published by the CK 12 Foundation，a nonprofit group that had been developing digital science and math books for about two years．The foundation paid teachers and other education professionals to write and edit them．The money came from a group financed by the Khosla Family．California cannot require schools to use the digital textbooks．Individual school districts will have to decide for themselves．Susan Martimo，a California Department of Education official，says she does not expect widespread use right away．Her best guess is that some schools with a lot of technology will be the first to use them，but only in addition to their traditional books．School administrators point out that the texts may be free online，but students need a way to access them．Not everyone has a computer or electronic reader．Schools could print out copies，but that would not help the environment．Also，there is the cost to train teachers to use digital textbooks effectively． 36．The Digital Textbook InitiativeD．A．will probably take effect in six yearsB．covers all the high school subjectsC．has been approved by all statesD．is advocated by California state governor37．Digital textbooks are most meaningful in that they are toA．A．help save money B．benefit the environmentC．provide interesting materials D．reduce students'heavy burden38．Which of the following is TRUE of the CK 12 Foundation？DA．It publishes all the books for students free of charge B．It provides money to write and edit all the textbooks in the USAC．It is organized and supported by Khosla Family D．It offers digital math and science materials for high schools39．According to Susan Martimo，digital textbooks willC．A．come into fashion from now onB．soon replace traditional onesC．first be adopted by well-equipped schoolsD．surely be approved by school districts40．It can be inferred from the last paragraph thatB．A．schools are reluctant to print out copiesB．the program is not easy to carry outC．students have no access to the computersD．teachers fail to use the textbooks effectively．

When we worry about who might be spying on our private lives， we usually think about the Federal agents． But the private sector outdoes（超越） the government every time． It's Linda Tripp， not the FBI， who is facing charges under Maryland's laws against secret telephone taping． It's our banks， not the Internal Revenue Service （IRS）， that pass our private financial data to telemarketing（电话营销） firms． Consumer activists are pressing Congress for better privacy laws without much result so far． The legislators（立法者） lean toward letting business people track our financial habits virtually（事实上） at will． As an example of what's going on， consider U．S． Bancorp， which was recently sued（控告） for deceptive （欺诈性的）practices by the state of Minnesota． According to the lawsuit， the bank supplied a telemarketer called Member Works with sensitive customer data such as names， phone numbers， bank-account and credit-card numbers， Social Security numbers， account balances and credit limits． With these customer lists in hand， Member Works started dialing for dollars - selling dental plans， videogames， computer software and other products and services． Customers who accepted a "free trial offer" had 30 days to cancel． If the deadline passed， they were charged automatically through their bank or credit-card accounts． U．S． Bancorp collected a share（股份） of the revenues（收入）． Customers were doubly deceived， the lawsuit claims． They didn't know that the bank was giving account numbers to Member Works． And if customers asked， they were led to think the answer was no． The state sued Member Works separately for deceptive selling． The company defends that it did anything wrong． For its part， U．S． Bancorp settled without admitting any mistakes． But it agreed to stop exposing its customers to non-financial products sold by outside firms． A few top banks decided to do the same． Many other banks will still do business with Member Works and similar firms． And banks will still be mining（开采） data from your account in order to sell you financial products， including things of little value， such as credit insurance and credit-card protection plans． You have almost no protection from businesses that use your personal accounts for profit． For example， no federal law shields （保护）"transaction（交易；办理） and experience" information - mainly the details of your bank and credit-card accounts． Social Security numbers are for sale by private firms． They've generally agreed not to sell to the public． But to businesses， the numbers are an open book． Self-regulation doesn't work． A firm might publish a privacy-protection policy， but who enforces（实施） it？ Take U．S． Bancorp again． Customers were told， in writing， that "all personal information you supply to us will be considered confidential．" Then it sold your data to Member Works． The bank even claims that it doesn't "sell" your data at all． It merely "shares" it and reaps（收获） a profit． Now you know．（1）Contrary to popular belief， the author finds that spying on people's privacy ____ ．A． is mainly carried out by means of secret tapingB． has been intensified with the help of the IRSC． is practiced exclusively（独自的） by the FBID． is more prevalent（流行的；普遍的） in business circles（2）We know from the passage that ____ ．A． legislators are acting to pass a law to provide better privacy protectionB． most states are turning a blind eye to the deceptive practices of private businessesC． the state of Minnesota is considering drawing up laws to protect private informationD． lawmakers are inclined to give a free hand to businesses to inquire into customers' buying habits（3）When the "free trial" deadline is over， you'll be charged without notice for a product or service if ____ ．A． you fail to cancel it within the specified periodB． you happen to reveal your credit card numberC． you find the product or service unsatisfactoryD． you fail to apply for extension of the deadline（4）Businesses do not regard information concerning personal bank accounts as private because ____ ．A． its revelation will do no harm to consumers under the current protection policyB． it is considered "transaction and experience" information unprotected by lawC． it has always been considered an open secret by the general publicD． its sale can be brought under control through self-regulation（5）We can infer from the passage that ____ ．A． banks will have to change their ways of doing businessB． privacy protection laws will soon be enforcedC． consumers' privacy will continue to be invadedD． "free trial" practice will eventually be banned

Each summer, no matter how pressing my work schedule, I take off one day exclusively for my son. We call it dad-son day. This year our third stop was the amusement park, where he discovered that he was tall enough to ride one of the fastest roller coasters(过山车) in the world. We blasted through face-stretching turns and loops for ninety seconds. Then, as we stepped off the ride, he shrugged and, in a distressingly calm voice, remarked that it was not as exciting as other rides he’’d been on. As I listened, I began to sense something seriously out of balance. Throughout the season, I noticed similar events all around me. Parents seemed hard pressed to find new thrills for indifferent kids. Surrounded by ever-greater stimulation, their young faces were looking disappointed and bored. Facing their children’’s complaints of "nothing to do", parents were shelling out large numbers of dollars for various forms of entertainment. In many cases the money seemed to do little more than buy transient relief from the terrible moans of their bored children. This set me. pondering the obvious question: "How can it be so hard for kids to find something to do when there’’s never been such a range of stimulating entertainment available to them " What really worries me is the intensity of the stimulation. I watch my little daughter’’s face as she absorbs the powerful onslaught (冲击) of arousing visuals and bloody special effects in movies. Why do children immersed in this much excitement seem starved for more That was, I realized, the point. I discovered during my own reckless adolescence that what creates excitement is not going fast, but going faster. Thrills have less to do with speed than changes in speed. I’’m concerned about the cumulative effect of years at these levels of feverish activity. It is no mystery to me why many teenagers appear apathetic (麻木的) and burned out, with a "been there, done that" air of indifference toward much of life. As increasing numbers of friends’’ children are prescribed medications ― stimulants to deal with inattentiveness at school or anti-depressants to help with the loss of interest and joy in their lives ― I question the role of kids’’ boredom in some of the diagnoses. My own work is focused on the chemical imbalances and biological factors related to behavioral and emotional disorders. These are complex problems. Yet I’’ve been reflecting more and more on how the pace of life and the intensity of stimulation may be contributing to the rising rates of psychiatric problems among children and adolescents in our society. In order to alleviate children’’s boredom, the author would probably suggest________. A．adjusting the pace of life and intensity of stimulationB．promoting the practice of dad-son daysC．consulting a specialist in child psychologyD．balancing school work with extracurricular activities
