They like using the Internet．They have lots of pocket money to spend．And they spend a higher proportion of it online than the rest of us．Teenagers are just the sort of people an online seller is interested in, and the things they want to buy－games, CDs and clothing－are easily sold on the Web.

But paying online is a tricky business for consumers who are too young to own credit cards．Most have to use a parent’s card．They want a facility that allows them to spend money.

That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic．If successful, these products can stimulate online sales.

In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK．Most teenagers have access to the Internet at home or at school－88 percent in the US, 69 percent in the UK．According to the Jupiter Research, one in eight of those with Internet access has bought something online－mainly CDs and books.

In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children．Pressing parents to spend online is less productive than pressing on the high street．They are more likely to ask “Why?” if you ask to spend some money online.

One way to help teenagers change notes and coins into cybercast is through prepaid cards such as Internet Cash in the US and Smart cards in the UK．Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as￡20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account.

What does the word “They” in paragraph 1 refer to?

       A．Sellers.     B．Buyers.     C．Teenagers.       D．Parents.

According to the passage, which of the following statements is TRUE?

       A．More than half of the teenagers in the US and the UK have Internet access．

       B．Teenagers pay for goods online with their own credit cards.

       C．Most teenagers in the US and the UK have bought something online.

       D．Teenagers found it easier to persuade parents to buy online than in a shop.

A new way to help teenagers shop online is to use ______.

       A．a new machine B．special coins and notes

       C．prepaid cards    D．pay-as-you-go mobile phones

What is the passage mainly about?

       A．Online shopping traps.        B．Internet users in the US and the UK.

       C．New credit cards for parents.  D．The arrival of cyber pocket money.

A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami（海啸） warnings just three minutes later. The country has one of the best earthquake early warning systems in the world.

There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes.

There are also concrete(混凝土) sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami.

Costas Synolakis ，a tsunami expert at the University of Southern California in Los Angeles said，"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event."

He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan.

The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas.

Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves.

Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted

Where can this passage probably be adapted from?

    A．A magazine on science       B．A fairy Tale 

C．A scientific fantasy book     D．A newspaper  

Which of the following statements NOT true ?

    A. A terrible earthquake hit the northeastern coast of Japan

    B. It was also the worst earthquake in Japan

C. The 9.0 earthquake was the fourth most powerful earthquake ever recorded in Japan

D. Japan's concrete sea walls was unable to handle such high waves.

According to Costas Synolakis, why did Japan suffer such a loss?

  A. The country has never experienced any event as big as this one over the past 150 years

B. Japan has the best earthquake early warning systems in the world.

C. There are not concrete sea walls around all of the Japanese coastline

D. The government didn’t announce its first tsunami warnings three minutes earlier.

A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says.

  Researchers studied the effects of tranexamic acid （凝血酸）, or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.

  The drug is commonly used in wealthy countries during elective surgeries(外科手术) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection（注射） and would be relatively easy to introduce, even in poor countries, experts said.

  Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots （凝块）in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.

  For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.

The underlined word” hemorrhage” in Paragraph 2 probably means ________

 A. serious illness    B. heart disease     C. heavy bleeding   D. lack of drug

What can we learn about TXA from the passage?

 A. It can only be made in England     B. It was only used in operations before

 C. It is a patented drug              D. It is mainly used in poor countries

Doctors were worried about using TXA because ________

 A. a lot of patients died unexpectedly after using it

 B. it has no treatment effect on patients

 C. it can cause blood clots or stroke

 D. they hadn’t used it on accident victims before

What do we know from the last paragraph?

 A. It is a pity that TXA wasn’t widely used on injured patients before

 B. Tests have proved that TXA can be used on children

 C. People between 5 and 45 should be injected with TXA every year

 D. Accidents are the first leading cause of death worldwide.

A painter hangs his or her finished pictures on a wall, and everyone can see it. A composer writes a work, but no one can hear it until it is performed. Professional singers and players have great responsibilities, for the composer is utterly dependent on them.

 A student of music needs as long and arduous a training to become a performer as a medical student needs to become a doctor. Most training is concerned with technique, for musicians have to have the muscular proficiency of an athlete or a ballet dancer. Singers practice breathing every day, as their vocal chords would be inadequate without controlled muscular support. String players practice moving the fingers of the left hand up and down, while drawing the bow to and fro with the right arm----????????two entirely different movements. Singers and instruments have to be able to get every note perfectly in tune. Pianists are spared this particular anxiety, for the notes are already there, waiting for them, and it is the piano tuner's responsibility to tune the instrument for them. But they have their own difficulties; the hammers that hit the string have to be coaxed not to sound like percussion, and each overlapping tone has to sound clear. This problem of getting clear texture is one that confronts（使面对）student conductors: they have to learn to know every note of the music and how it should sound, and they have to aim at controlling these sounds with fanatical but selfless authority. Technique is of no use unless it is combined with musical knowledge and understanding. Great artists are those who are so thoroughly at home in the language of music that they can enjoy performing works written in any century.

   A. to tell us we use different sense at paints and music

   B. to recommend music needs more technique

   C. to inform us that to become a musician needs long and arduous training

20. If you are a string performer, you have to _____________.

   A. use your left hand to draw the bow and the right to move up and down

   B. have your both hands perform the same movements.

   C. own technique, musical knowledge and understanding

   D. practice more and more without any training

21. The problem of getting clear texture is that ____________.

  A. confronts student conductors

  B. the student conductors have to know every note and how it should sound and how to control the sounds fanatically.

 C. the sounds are too easy to control

 D. the composer’s work cannot be seen on the wall.

22. According to the passage, _______________.

 A. a composer cannot perform the music at all.

 B a composer has to utterly depend on student conductors

 C. student conductors need more training and knowledge on music to be great artists.

 D. Great artists are thoroughly at home in the language of music.
