.Music and Driving

Listening to loud music while driving can seriously hamper reaction times and cause accidents，new research suggests.

A Canadian study found people took up to 20% longer to perform. physical and mental tasks to loud music. If motorists were delayed that long at the wheel they could suffer a fatal crash，warned the RAC．Foundation， a British motoring organization. Edmund King， the RAC Foundation"s executive director， said the study showed that" not only is loud music a nuisance to other，it could also be the cause of accidents".

Earlier research by the RAC Foundation found drivers were twice as likely to skip a red light while listening to music. In the Canadian study volunteers carried out tasks whiie listening to levels of noise varying from 53 decibels（equivalent to an office environment） to 95 decibels （equivalent to an oil rig）. Researchers found reactions to be significantly decreased at higher noise levels for both physical and mental work. At 95 decibels reaction times to tasks that involve decision making plummeted（骤然减少） by 20%. Edmund King said:"The findings of the Canadian study are bad news for decibel-loving drivers， as they prove that not only is loud music a nuisance to others， it could also be the cause of accidents on the roads. "Drivers are at even greater risk if they listen to music with a pounding beat rather than more relaxed tunes， according to experts.

Conrad" King， consultant psychologist to the foundation， said:" It is important that drivers choose their music carefully when driving，as up-tempo music has been shown to cause drivers to have double the amount of accidents as those listening to slower music. "In general， if music is a-bove 60 beats per minute， listeners experience a faster rate and increased blood pressure. "It doesn"t matter if you listen to opera， classical or the latest rave music. It"s the speed of the beat that counts. "

According to scientific research， people may spend more time doing physical work if listening to loud music while doing the task. 查看材料

they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes that ambitious parents make. Generally, the child will be only too aware of what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children. However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child. Michael Li is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. Although Michaels mother knows very little about music, Michaels father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling. Michaels friend, Winston Chen, however, is not so lucky. Although both his parents are successful musicians, they set a too high standard for Winston. They want their son to be as successful as they are and so they enter him in every piano competition held. They are very unhappy when he does not win. "When I was your age, I used to win every competition I entered," Winstons father tells him. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy. Questions 19 to 22 are based on the passage you have just heard. 19. What is the right attitude in bringing up a child？ 20. What does the speaker tell us about Michaels father？ 21. What can we learn about Winston Chens parents？ 22. Why does Winston always seem quiet and unhappy？19．

A．He knows very little about music.

B．He is a member of a large orchestra.

C．He wants Michael to be a great trumpet player.

D．He never makes Michael enter music competitions.

If parents bring up a child with the aim of turning the child into a genius (天才), they will cause great damage to him. According to several leading educational psychologists (心理学家), this is one of the biggest mistakes which some parents make. Generally, the child will understand very well what the parent expects. But unrealistic parental expectations can cause great damage to children.

However, if parents are not unrealistic- about what they expect their children to do, but are hope ful in a sensible way, the child may succeed in doing very well -- especially if the parents are very supportive of their child.

Michael Li is very lucky. He is very fond of music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers twice a week for violin lessons. Although Michael's mother knows very little about music, she supports her son. Michael's father plays the trumpet(小号) in a large orchestra(管弦乐队). However, he never makes Michael enter music competitions if he is unwilling.

Michael's friend, Winston Chen, however, is not so lucky. Although both his parents are successful musicians, they set too high a standard for Winston. They want their son to be as successful as they are and so they make him enter every piano competition. They are very unhappy when he doesn't win. "When I was your age, I used to win every competition ! entered. "Winston's father tells him. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.

The main idea of the passage is ______.

A．how parents should make a child a musician

B．how parents should bring up a child

C．what differences there are between two kinds of parents

D．what aim of a child can be much easier to reach

听力原文： Ludwig Beethoven was born in Bonn, in the Rhineland. His father was a professional musician in the Court of The Elector of Cologne; he was often drunk, and he was a hard task-master to his son. Ludwig began learning violin and piano when he was only 5, and by the time he was 8 years old the began giving public concerts. He received very little education apart from music, but he was fortunate in having a good music teacher, the court organist, who recognized his abilities and taught him well. When he was 14, Ludwig was appointed second court organist, a post which gave him some opportunity to travel. He visited Vienna, where Mozart heard him play and said, "Watch that young fellow; he is going to cause a stir in the world." When he was 16 his mother died, and three years later his father was dismissed from his post at Court. Ludwig, with characteristic loyalty and devotion to his family, accepted responsibility both for his father and his two younger brothers.

Throughout his life Beethoven produced numerous musical works. First and foremost, Beethoven was a composer of extended music, that is, long works in several movements. His masterpieces remain the greatest and most personal compositions of one of the world's greatest musical thinkers. No composer has put more of himself into his music; everything he left, from anger to tenderness, from misery to hope is found there.

the devices may be causing hearing loss in my people. Some experts say people may be playing them too loud and for too long.

Researchers from Zogby International did a study for the American Speech-Langusge-Hearing Association. It involved 300 high school students and 1,000 adults. They were asked about their use of portable music devices. Some of the most popular are Apple Computer's iPud, C.D. players and portable laptop computers. 40 percent of students and adults said they set the sound levels, or volume, at high on their iPods. But students were two times more likely to play the music at a very loud volume. More than half of the students said they would probably not limit their listening time. And about a third said they were not likely to reduce the volume.

The study found that more than half of the students and less than 40 percent of the adults had at least one kind of hearing loss. Heating experts say part of the problem is the listening equipment people are using. They say large earphones that cover the whole ear are probably safer than the smaller earplugs that come with most music players. Earplugs are thought to be less effective than earphones in blocking out foreign noises.

Hearing loss may not be apparent for years. But once it happens, it is permanent. About 30 million Americans have some hearing loss. One third of them lost their heating as a result of loud noises.

How can listening equipment cause hearing loss in people？

(33)

A．People may use portable laptop computers to listen to music.

B．People may set them at high volume when they listen to music.

C．People may listen to music while walking on the street.

D．People may use large earphone when they listen to music.

The Biology of Music

Humans use music as a powerful way to communicate. It may also play an important role in love. But what is music, and how does it work its magic？ Science does not yet have all the answers.＜br＞

What are two things that make humans different from animals？ One is language, and the other is music. It is true that some animals can sing (and many birds sing better than a lot of people).＜br＞

However, the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals, have developed musical instruments.＜br＞

Music is a strange stuff. It is clearly different from language. However, people can use music to communicate things-- especially their emotions. When music is combined with speech in a song, it is a very powerful form. of communication. But, biologically speaking, what is music？＜br＞

If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true.＜br＞

Sometimes people who suffer brain damage lose their ability to process language. However, they don&39;t automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak or understand speech. He could, however, still compose music until his death ten years later. On the other hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech. This shows that the brain processes music and language separately.＜br＞

By studying the physical effects of music on the body, scientists have also learned a lot about how music influences the emotions. But why does music have such a strong effect on us？ That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That&39;s why it may be a way of showing your fitness to be someone&39;s mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes.＜br＞

And playing or singing those notes correctly suggests that your hearing is in excellent conditions. Finally,when a man sings to the woman he loves (or vice versa), it may be a way of showing off.＜br＞

However, Miller&39;s theory still doesn&39;t explain why certain combinations of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research.

Music

Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function: it not only moves people but also can shock people.＜br＞

Our eardrums can withstand sound within 20 to 80 decibels (分贝 ) . Once sound exceeds this limit, even beautiful music will become car-splitting noise and harm health. A strong blast (响声 ) of high sound can twist and break a solid iron sheet. High sound of 150 decibels can kill a healthy rat.＜br＞

In movies, sometimes the hero can produce a sound that ordinary people can&39;t hear and only those who have the same ability can feel. In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20,000 hz is called ultrasonic (超音波的). Dolphins, whales and bats can make such high-frequency sound. It does no harm to health.＜br＞

Sound less than 20 hz is called infrasonic (次声 ) waves. When we move, the air will vibrate.＜br＞

The vibration of air can produce infrasonic waves. As the frequency of infrasonic waves is close to that of people&39;s internal organs, infrasonic wave may cause resonance (共振) in human bodies. As a result, people&39;s vision may weaken and internal organs may rupture (断裂). However, whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low, it won&39;t damage internal organs or a person&39;s health. If the intensity of infrasonic wave exceeds 160 decibels, it is extremely harmful. When wind blows at a force of 3 or 4 over the sea, it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.

What could be the best title of the passage？ 查看材料

A.The power of music

B.The harms of noises

C.The magic of sound

D.The discovery of infrasonic waves

The Magic of Sound

Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays， music has an added function: it not only moves people but also can shock people. Is it true that an ordinary musical instrument can be so powerful？

Our eardrums can withstand sound within 20 to 80 decibels. Once sound exceeds this limit，even beautiful music will become ear-splitting noise and harm health. A strong blast of high sound can twist and break a solid iron sheet. __________ （46）

The noise from a plane"s engine is over 140 decibels. However， the sound of a flute is at most a few decibels. __________ （47） It has been proven that people who have worked in an environment with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.

In movies， sometimes the hero can produce a sound that ordinary people can"t hear and only those who have the same ability can feel. In nature， there is actually sound that is beyond our hearing. In physics， the sound that exceeds 20，000 Hz is called ultrasonic. __________ （48） It does no harm to health.

Sound less than 20 Hz is called infrasonic waves. When we move， the air will vibrate. __________ （49）

As the frequency of infrasonic waves is close to that of people"s internal organs， infrasonic wave may cause resonance in human bodies. As a result， people"s vision may weaken and internal organs may rupture. However， whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low， it won"t damage internal organs or a person"s health. __________ （50） When wind blows at a force of 3 or 4 over the sea， it will produce infrasonic waves of several decibels.

what you like to accomplish with your careers？" an American senator asked Time Warner executives recently. "You have sold your souls, but must you corrupt our nation and threaten our children as well？" At Time Warner, however, such questions are simply the latest manifestation of the soul-searching that has involved the company ever since the company was born in 1990. It's a self-examination that has, at different times, involved issues of responsibility, creative freedom and the corporate bottom line.

At the core of this debate is chairman Gerald Levin, 56, who took over from the late Steve Ross in the early 1990s. On the financial front, Levin is under pressure to raise the stock price and reduce the company's mountainous debt, which will increase to $ 17.3 billion after two new cable deals close. He has promised to sell off some of the property and restructure the company, but investors are waiting impatiently.

The flap over rap is not making life any easier for him. Levin has consistently defended the company's rap music on the grounds of expression. In 1992, when Time Warner was under fire for releasing Ice-T's violent rap song Cop Killer, Levin described rap as a lawful expression of street culture, which deserves an outlet. " The test of any democratic society, " he wrote in a Wall Street Journal column, " lies not in how well it can control expression but in whether it gives freedom of thought and expression the widest possible latitude, however disputable or irritating the results may sometimes be. We won't retreat when we face any threats. "

Levin would not comment on the debate last week, but there were signs that the chairman was backing off his hard-line stand, at least to some extent. During the discussion of rock singing verses at last month's stockholders' meeting, Levin asserted that "music is not the cause of society's ills" and even cited his son, a teacher in the Bronx, New York, who uses rap to communicate with students. But he talked as well about the "balanced struggle "between creative freedom and social responsibility, and he proclaimed that the company would launch a drive to develop standards for distribution and labeling of potentially objectionable music.

The 15-member Time Warner board is generally supportive of Levin and his corporate strategy. But insiders say some of them have shown their concerns in this matter. " Some of us have known for many, many years that the freedoms under the First Amendment are not totally unlimited , " says Luce. " I think it is perhaps the case that some people associated with the company have only recently come to realize this. "

An American senator criticized Time Warner for

A．its raising of the corporate stock price.

B．its self-examination of the soul.

C．its neglect of social responsibility.

D．its emphasis on creative freedom.
