1.Police in the popular resort city Virginia Beach recently began operating video surveillance cameras with controversial face recognition technology. Virginia Beach and Tampa in Florida two cities in the United States acquired the technology, which cost them $ 197, 000.” “Before we switched it on, we went through an extensive public education process with hearings and the involvement of citizen groups and minority groups, who helped write the policies we are using, " said deputy police chief Greg Mullen. A citizens' auditing committee has the right to perform. unannounced spot checks on police headquarters to make sure the technology is not being misused.Three of the city's 13 cameras are linked full time to the face recognition system, though the others can be activited as needed. The database of wanted people is updated every day. So far, the system has failed to produce a single arrest, though it has generated a few false alarms. It works by analyzing faces based on a series of measurements, such as the distance from the tip of the nose to the chin or the space between the eyes. Critics say it is highly inaccurate and can be easily fooled. Mullen, who sees the system eventually being linked to the databases of other city, state and federal law enforcement agencies to track criticals and suspected terrorists, said, "The system doesn't look at skin color or your hair or your gender. It takes human prejudices out of the equation. ""This technology has little or no effect on the crime rate but it does have an effect on people's behavior. People feel cowed, " said Bruce Steinhardt, who directs the technology. Despite the fact that tests have shown faces recognition only works in around 30% cases, the ACLU is alarmed that the technology may soon spread to airports. The organization also fears it could potentially be used to monitor individual's political activities to harass law-abiding citizens." This kind of surveillance should be subject to the same procedures as wiretaps. Law enforcement agencies should justify why they need it and it should be tightly limited, otherwise it will soon become a tool of social control, " said Mihir Kshisagar of the Electronic Information Privacy Center. Nor does such criticism come exclusively from the political left. Lawyer John Whitehead, founder of the conservative Rutherford Institute, wrote in an editorial that the technology threatened the right of each U. S. citizen to participate in society. "After all, that is exactly what constant surveillance is—the ultimate implied threat of coercion, " he wrote.What does Mullen's statement in Paragraph 1 indicate?A.Police is confident in using the technology.B.Police has made preparation for the use of the technology.C.Citizens have rights over managing the technology.D.Police has gone through public education process.

    Passage 1
    A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road.
    The car's sensors check odors inside the car and monitor a driver's sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed' firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver's palm.
    Other carmakers have developed similar detection systems. For example, Sweden's Volvo has developed a breathalyzer attached to a car's seat belt that drivers must blow into before the engine will start.
    Nissan's new concept vehicle also includes a dashboard-mounted camera that tracks a driver's alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest.
    The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology."For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.
    The car's seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it's going to register, so we need to study what's the appropriate level for the system to activate," he says.

    According to Doi,__________.

    Credit Card Only Works When Spoken To

    A credit card that will not work unless it hears its owner's voice could become an
    important weapon in the fight against fraud(欺骗).
    The card requires users to give a spoken password that it recognizes using a built-in
    voice-recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using
    someone else's credit card details to buy goods online.
    A model built by engineers at Beepcard in Santa Monica,California,represents the
    first attempt to pack a microphone,a loudspeaker,a battery and a voice-recognition chip
    into a standard-sized credit card.
    They are not quite there yet:the card is the length and width of an ordinary credit card,
    but it is still about three times as thick.The company now plans to make it thinner.
    The voice card is based on an earlier Beepcard technology designed to prevent fraud in
    online transactions.This earlier card has no microphone,but has a built-in loudspeaker
    that it uses to " squawk"(发出叫声)a voice ID signal via a computer's microphone to an
    online server.
    By verifying(证实)that the signal matches the card details,the server can establish
    that the user is not simply keying in a credit card number but actually has the card to hand.
    The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
    This prevents fraudsters recording the beeps, noting the card details and then playing
    back the audible ID when they key in the details later.But this earlier technology cannot
    prevent fraudulent use of stolen cards.The new one can.
    The new voice card also identifies itself by its ID squawk,but it will not do this until it
    has verified the legitimate(合法的)user's spoken password. Thieves will be unable to use
    the card because even if they knew the password they would have to be able to copy the
    owner's voice with a high degree of accuracy.
    The challenge for Beepcard has been to develop voice-recognition and audio circuitry
    that can be powered by a mini battery embedded(嵌入的)in a credit card. To maximize
    battery life,the electronics are only switched on when the card is being used.Pressing a
    button on the card's surface prompts it to utter "Say your password" in female voice.If the
    voice-recognition software proves that the password is authentic(真实的),it sends its ID
    squawk which the server then identifies,allowing the transaction to proceed.

    What is the problem with the model card?
    A:It is too large.
    B:It is too thick.
    C:It can't be used in online transactions.
    D:It doesn't have a loudspeaker.

    Technology Transfer in Germany

    When it comes to translating basic research into industrial success,few nations can
    match Germany.Since the 1940s,the nation's vast industrial base has been fed with a
    constant stream of new ideas and expertise from science.And though German prosperity
    (繁荣)has faltered(衰退)over the past decade because of the huge cost of unifying east
    and west as well as the global economic decline , it still has an enviable(令人羡慕的)
    record for turning ideas into profit.
    Much of the reason for that success is the Fraunhofer Society,a network of research
    institutes that exists solely to solve industrial problems and create sought-after technologies.
    But today the Fraunhofer institutes have competition.Universities are taking an ever larger r
    ole in technology transfer,and technology parks are springing up all over.These efforts
    are being complemented by the federal programmes for pumping money into start-up companies,
    Such a strategy may sound like a recipe for economic success,but it is not without its
    critics.These people worry that favouring applied research will mean neglecting basic
    science,eventually starving industry of fresh ideas.If every scientist starts thinking like an
    entrepreneur(企业家),the argument goes , then the traditional principles of university
    research being curiosity-driven,free and widely available will suffer.Others claim that
    many of the programmes to promote technology transfer are a waste of money because half
    the small businesses that are promoted are bound to go bankrupt within a few years.
    While this debate continues,new ideas flow at a steady rate from Germany's research
    networks,which bear famous names such as Helmholtz,Max Planck and Leibniz.Yet it is the
    fourth network,the Fraunhofer Society,that plays the greatest role in technology transfer.
    Founded in 1949,the Fraunhofer Society is now Europe's largest organisation for
    applied technology,and has 59 institutes employing 12,000 people.It continues to grow.
    Last year,it swallowed up the Heinrich Hertz Institute for Communication Technology in
    Berlin.Today,there are even Fraunhofers in the U.S. and Asia.

    Coming Soon to a Theater Near You!
    What are special effects?Do you enjoy movies that use a lot of special effects Dinosaurs(恐 龙)from the distant past!Space battles from the distant future!There has been a revolution in special effects,and it has transformed the movies we see.
    The revolution began in the mid 1970s with George Lucas's Star Wars,a film that stunned (使震惊)audiences. That revolution continues to the present,with dramatic changes in special-effects technology.The company behind these changes is Lucas's Industrial Light&Magic (ILM).And the man behind the company is Dennis Muren,who has worked with Lucas since Star Wars.
    Muren's interest in special effects began very early.At the age of 6,he was photographing toy dinosaurs and spaceships.At10,he had an 8 millimeter movie camera and was making these things move through stop-motion.(Stop-motion is a process in which objects are shot with a camera,moved slightly,shot again,and so on .When the shots are put together,the objects appear to move.)
    Talk to Muren and you'll understand what ILM is all about:taking on new challenges.By 1989,Muren decided he had pushed the old technology as far as it would go.
    He saw computer graphics(图像)( CG ) technology as the wave of the future and took a year off to master it.
    With CG technology,images can be scanned into a computer for processing,for example, and many separate shots can be combined into a single image.CG technology has now reached the point,Muren says,where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel(续集),The Lost World,the stars of which were computer-generated dinosaurs,suggests that this may very well be true.

    Muren feels that with CG technology,special effects can be used to make movies more expensive.
    A: Right
    B: Wrong
    C: Not mentioned

    答案:C
    解析:
    文章第二段开始是The revolution began in the mid 1970s with George Lucas's Star Wars,表明这场革命始于20世纪70年代,该判断正确。


    第二段第二句提到“with dramatic changes in special-effects technology... behind these changes is...ILM",由此推断结论正确。


    第三段虽然提到了很小就对电影产生了兴趣,但文章并没有涉及他是否很早就上学了,所以选C。


    第三段中间有“At 10 , he had an 8 millimeter movie camera... move through stop-mo-tion",特写是不动的影像,所以该判断错误。


    文章第三段提到,利用“CG technology”可以使不同的镜头组合成一个图像,而当利用特写镜头时," When the shots are put together , the objects appear to move",当不同的特写组合到一起时,物体似乎在移动,所以选B。


    文章最后一段“special effects can be used to do... that movies can tell stories better than ever before",即特效可以更好地用来讲故事,但没有提及是否使得电影的造价提高,因此选C。


    最后一段说到特效可以“tell stories better than ever before",后面还有“this may very well be true",我们无从判断今天的电影人是否为了特效而特效,不关心电影的故事,因此选C。

    Credit Card Only Works When Spoken To

    A credit card that will not work unless it hears its owner's voice could become an
    important weapon in the fight against fraud(欺骗).
    The card requires users to give a spoken password that it recognizes using a built-in
    voice-recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using
    someone else's credit card details to buy goods online.
    A model built by engineers at Beepcard in Santa Monica,California,represents the
    first attempt to pack a microphone,a loudspeaker,a battery and a voice-recognition chip
    into a standard-sized credit card.
    They are not quite there yet:the card is the length and width of an ordinary credit card,
    but it is still about three times as thick.The company now plans to make it thinner.
    The voice card is based on an earlier Beepcard technology designed to prevent fraud in
    online transactions.This earlier card has no microphone,but has a built-in loudspeaker
    that it uses to " squawk"(发出叫声)a voice ID signal via a computer's microphone to an
    online server.
    By verifying(证实)that the signal matches the card details,the server can establish
    that the user is not simply keying in a credit card number but actually has the card to hand.
    The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
    This prevents fraudsters recording the beeps, noting the card details and then playing
    back the audible ID when they key in the details later.But this earlier technology cannot
    prevent fraudulent use of stolen cards.The new one can.
    The new voice card also identifies itself by its ID squawk,but it will not do this until it
    has verified the legitimate(合法的)user's spoken password. Thieves will be unable to use
    the card because even if they knew the password they would have to be able to copy the
    owner's voice with a high degree of accuracy.
    The challenge for Beepcard has been to develop voice-recognition and audio circuitry
    that can be powered by a mini battery embedded(嵌入的)in a credit card. To maximize
    battery life,the electronics are only switched on when the card is being used.Pressing a
    button on the card's surface prompts it to utter "Say your password" in female voice.If the
    voice-recognition software proves that the password is authentic(真实的),it sends its ID
    squawk which the server then identifies,allowing the transaction to proceed.

    The voice credit card is an important invention because
    A:it can be made cost-effectively.
    B:it can leave voice messages.
    C:it makes online shopping easy.
    D:it makes fraud difficult.

    Technology Transfer in Germany

    When it comes to translating basic research into industrial success,few nations can
    match Germany.Since the 1940s,the nation's vast industrial base has been fed with a
    constant stream of new ideas and expertise from science.And though German prosperity
    (繁荣)has faltered(衰退)over the past decade because of the huge cost of unifying east
    and west as well as the global economic decline , it still has an enviable(令人羡慕的)
    record for turning ideas into profit.
    Much of the reason for that success is the Fraunhofer Society,a network of research
    institutes that exists solely to solve industrial problems and create sought-after technologies.
    But today the Fraunhofer institutes have competition.Universities are taking an ever larger r
    ole in technology transfer,and technology parks are springing up all over.These efforts
    are being complemented by the federal programmes for pumping money into start-up companies,
    Such a strategy may sound like a recipe for economic success,but it is not without its
    critics.These people worry that favouring applied research will mean neglecting basic
    science,eventually starving industry of fresh ideas.If every scientist starts thinking like an
    entrepreneur(企业家),the argument goes , then the traditional principles of university
    research being curiosity-driven,free and widely available will suffer.Others claim that
    many of the programmes to promote technology transfer are a waste of money because half
    the small businesses that are promoted are bound to go bankrupt within a few years.
    While this debate continues,new ideas flow at a steady rate from Germany's research
    networks,which bear famous names such as Helmholtz,Max Planck and Leibniz.Yet it is the
    fourth network,the Fraunhofer Society,that plays the greatest role in technology transfer.
    Founded in 1949,the Fraunhofer Society is now Europe's largest organisation for
    applied technology,and has 59 institutes employing 12,000 people.It continues to grow.
    Last year,it swallowed up the Heinrich Hertz Institute for Communication Technology in
    Berlin.Today,there are even Fraunhofers in the U.S. and Asia.

    The Fraunhofer Society is the largest organisation for applied technology in
    A:Asia.
    B: U.S.A.
    C:Europe.
    D:Africa.

    答案:C

    Coming Soon to a Theater Near You!
    What are special effects?Do you enjoy movies that use a lot of special effects Dinosaurs(恐 龙)from the distant past!Space battles from the distant future!There has been a revolution in special effects,and it has transformed the movies we see.
    The revolution began in the mid 1970s with George Lucas's Star Wars,a film that stunned (使震惊)audiences. That revolution continues to the present,with dramatic changes in special-effects technology.The company behind these changes is Lucas's Industrial Light&Magic (ILM).And the man behind the company is Dennis Muren,who has worked with Lucas since Star Wars.
    Muren's interest in special effects began very early.At the age of 6,he was photographing toy dinosaurs and spaceships.At10,he had an 8 millimeter movie camera and was making these things move through stop-motion.(Stop-motion is a process in which objects are shot with a camera,moved slightly,shot again,and so on .When the shots are put together,the objects appear to move.)
    Talk to Muren and you'll understand what ILM is all about:taking on new challenges.By 1989,Muren decided he had pushed the old technology as far as it would go.
    He saw computer graphics(图像)( CG ) technology as the wave of the future and took a year off to master it.
    With CG technology,images can be scanned into a computer for processing,for example, and many separate shots can be combined into a single image.CG technology has now reached the point,Muren says,where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel(续集),The Lost World,the stars of which were computer-generated dinosaurs,suggests that this may very well be true.

    At the age of 10,Muren was able to use computer graphics technology to make things move.
    A: Right
    B: Wrong
    C: Not mentioned

    答案:B
    解析:
    文章第二段开始是The revolution began in the mid 1970s with George Lucas's Star Wars,表明这场革命始于20世纪70年代,该判断正确。


    第二段第二句提到“with dramatic changes in special-effects technology... behind these changes is...ILM",由此推断结论正确。


    第三段虽然提到了很小就对电影产生了兴趣,但文章并没有涉及他是否很早就上学了,所以选C。


    第三段中间有“At 10 , he had an 8 millimeter movie camera... move through stop-mo-tion",特写是不动的影像,所以该判断错误。


    文章第三段提到,利用“CG technology”可以使不同的镜头组合成一个图像,而当利用特写镜头时," When the shots are put together , the objects appear to move",当不同的特写组合到一起时,物体似乎在移动,所以选B。


    文章最后一段“special effects can be used to do... that movies can tell stories better than ever before",即特效可以更好地用来讲故事,但没有提及是否使得电影的造价提高,因此选C。


    最后一段说到特效可以“tell stories better than ever before",后面还有“this may very well be true",我们无从判断今天的电影人是否为了特效而特效,不关心电影的故事,因此选C。
