2.Ⅳ. Reading Comprehension (60 points)Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.Passage OneThere was a nasty (肮脏的，卑鄙的) accident in our town not long ago, and I saw it happen. I was standing near a road which was under repair, not doing anything special—just watching the men at work. It was not far from the new motorway (高速公路) that runs past the town. It was an old road that used to be very busy—and dangerous before the motorway was built. Today, most cars use the new "superhighway" and the old road is pretty quiet, although cars do often come off the motorway into the town faster than they should.Anyway, the men were repairing part of the road and there were signs up for at least 200 meters, telling everybody that the road was narrower than usual. Most of the drivers in both directions saw the signs and slowed down.Then three cars came along close together, the third one moving at a very high speed. The first one pas sed the workmen and wanted to turn left. Meanwhile the third car came flying past the second one. The sec and car stopped. I think the driver knew something was going to happen. It did. The third car had no chance of stopping. Its driver braked (刹车) and pulled over to miss the first car and went right off the road.There were four people in that car: a man, two women and a child. The child was a boy of nine. I read later that they were going shopping—just shopping, nothing more important than that. The driver was badly hurt. The little bay was hurt too. Both the women were killed immediately. One of them was the driver's wife and the other was the mother of the little boy. They never got to the shops.36. The old road ______.A. was very busy though there was a new motorwayB. was never very busyC. was always very busy and dangerousD. was very busy and dangerous before the construction of the new motorway

3.New drivers age far more______to have accidents than experienced drivers.A．possibleB．likelyC．probableD．unlikely

4.What’s the cause of the crosswalk safety problem according to the test?A. There’re many cars and buses on the road.B. Pedestrians are careless.C. Crosswalks are crowded.D. Drivers don’t give way.

参考答案和解析
正确答案： A
解析：
因果关系的找寻和判断。录音中指出许多可能是由睡眠引起的道路事故，但却列入其他原因之下，如精神不集中，没有看到其他车辆和错判速度或距离。面对这一情况，几乎没有调查者对司机出现上述情况的原因进行更深的研究。而对于司机来说，出于各种原因including the fear of prosecution and possible difficulties with insurance claims（怕被追究责任或在保险索赔时遇到麻烦），他们更愿意承认没有集中精神而非开车时睡着了。由此可见选项B，C和D的内容在录音中均有涉及。只有A项的内容与录音原文不符。

    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 RAG 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 RAG Foundation found drivers were twice as likely to skip a red light while listening to music.In the Canadian study volunteers carried out tasks while 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 ahove 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.
    A: Right
    B: Wrong
    C: Not mentioned

    答案：A
    解析：
    本题给出的信息是正确的。在文章第二段第一句话中提到“... people took up to 20% longer to perform physical and mental tasks to loud music.”由此可见，只要听着声音较大的音乐，无论是进行体力劳动还是脑力劳动大约都会多花费20%的时间。


    本题给出的信息是错误的。在文章第二段最后一句话中提到了埃德蒙·金的观点" not only is loud music a nuisance to others , it could also be the cause of accidents"，由此可见，吵闹的音乐不光会影响到别人，还会导致车祸，所以他并不认为大声的音乐时驾驶员没有害处。


    文章没有谈到这方面的信息。文章中只在最后一段提到“if music is above 60 beats per minute , listeners experience a faster heart rate and increased blood pressure.”如果每分钟音乐的节拍超过60下，听者就会感到心跳加速和血压增高。全文没有任何地方提到了喧闹的音乐是否会造成心脏病发作。


    本题给出的信息是错误的。在第三段中提到：" At 95 decibels reaction times to tasks that involve decision making plummeted by 20% .”。只要抓住这一细节，即可得出答案。由这句话可以知道，减少的幅度是20%而不是53%。


    文章没有谈到这方面的信息。全文完全没有提到爵士乐这种音乐形式，只提到了节奏感较强以及较为轻松的音乐。


    本题给出的信息是正确的。文章最后一段开头就提到了康拉德·金，他说：" It is important that drivers choose their music carefully when driving.”并指出了需要慎重选择音乐的原因。


    本题给出的信息是正确的。文章最后一句话指出：" It's the speed of the beat thatcounts.”这里count意思是“重要”，所以我们很容易得出结论，音乐节拍的速度是一个重要的衡量标准。

    Storms Sink Ships

    Rescuers have found the bodies of over 130 people killed in two ferry disasters in
    Bangladesh.The accidents happened during a storm that hit the country on April 21.
    Hundreds more are missing or feared dead.
    The two ferries sank in different rivers near the capital city of Dhaka as strong winds and
    rain hit the South Asian country.
    The government has since banned all ferries and other boats from travelling at night
    during the April-May stormy season.
    One of the ferries,MV Mitali,was carrying far more people than it was supposed to.
    About 400 passengers fitted into a space made for just 300,police said.The second ferry
    carried about 100 passengers.
    "The number of deaths is certain to rise,"said an official in charge of the rescue work.
    "No one really knows how many people were on board the ferry or how many of them
    survived."
    Ferries in Bangladesh don't always keep passenger lists,making it difficult to determine
    the exact number of people on board.
    Besides the ferry accidents,at least 40 people were killed and 400 injured by lightning
    strikes,falling houses and trees and the sinking of small boats.
    Storms are common this time of year in Bangladesh,as are boating accidents.Ferry
    disasters take away hundreds of lives every year in a nation of 130 million people.
    Officials blame these river accidents on a lack of safety measures,too many passengers
    in boats and not enough checks on weather conditions.
    Ferries are a common means of transport in Bangladesh.It is a country covered by
    about 230 rivers.Some 20, 000 ferries use the nation's waterways（水路）every year.
    And many of them are dangerously overcrowded（过度拥挤）.
    Since 1977,more than 3,000 people have died in some 260 boating accidents.

    Which of the following is NOT mentioned as a cause of the boating accidents?
    A:Strong winds.
    B:Bad weather conditions.
    C:Blockage of waterways.
    D:Lack of safety measures.

    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 RAG 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 RAG Foundation found drivers were twice as likely to skip a red light while listening to music.In the Canadian study volunteers carried out tasks while 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 ahove 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."

    Besides car accidents,loud music may also cause heart attack.
    A: Right
    B: Wrong
    C: Not mentioned

    答案：C
    解析：
    本题给出的信息是正确的。在文章第二段第一句话中提到“... people took up to 20% longer to perform physical and mental tasks to loud music.”由此可见，只要听着声音较大的音乐，无论是进行体力劳动还是脑力劳动大约都会多花费20%的时间。


    本题给出的信息是错误的。在文章第二段最后一句话中提到了埃德蒙·金的观点" not only is loud music a nuisance to others , it could also be the cause of accidents"，由此可见，吵闹的音乐不光会影响到别人，还会导致车祸，所以他并不认为大声的音乐时驾驶员没有害处。


    文章没有谈到这方面的信息。文章中只在最后一段提到“if music is above 60 beats per minute , listeners experience a faster heart rate and increased blood pressure.”如果每分钟音乐的节拍超过60下，听者就会感到心跳加速和血压增高。全文没有任何地方提到了喧闹的音乐是否会造成心脏病发作。


    本题给出的信息是错误的。在第三段中提到：" At 95 decibels reaction times to tasks that involve decision making plummeted by 20% .”。只要抓住这一细节，即可得出答案。由这句话可以知道，减少的幅度是20%而不是53%。


    文章没有谈到这方面的信息。全文完全没有提到爵士乐这种音乐形式，只提到了节奏感较强以及较为轻松的音乐。


    本题给出的信息是正确的。文章最后一段开头就提到了康拉德·金，他说：" It is important that drivers choose their music carefully when driving.”并指出了需要慎重选择音乐的原因。


    本题给出的信息是正确的。文章最后一句话指出：" It's the speed of the beat thatcounts.”这里count意思是“重要”，所以我们很容易得出结论，音乐节拍的速度是一个重要的衡量标准。

  • 第20题：

    单选题
    Why haven’t British government bodies initiated any studies?
    A

    Because they do not take the problem of sleepy drivers on motorways as of great significance.

    B

    Because they have not been aware of the seriousness of the problem of sleepy drivers.

    C

    Because they have no figures on the number of accidents caused by drivers’sleepiness.

    D

    Because they plan to support relevant researches or a general study on “driver behaviour”.


    正确答案： A
    解析：
    因果关系的判断和理解。关于英国政府为何尚未对睡眠引发车祸的问题进行研究，录音中指出“The Department of Transport claims that it is ‘aware of the problems’, but does not regard it as a high-priority issue…”，可知英国交通部虽已意识到该问题，但并不认为它是头等重要的事情。A项中的of great significance与该句中的high-priority表达意思相一致。因此，选项A为正确答案。

  • 第21题：

    单选题
    Under what circumstance can we tell an accident is probably caused by sleepiness?
    A

    If traffic is light and vehicles are well-spaced on the road.

    B

    When there is only one car involved in the accident.

    C

    If there is no skid marks or other signs of braking on the road.

    D

    All of the above.


    正确答案： B
    解析：
    事实细节的找寻和判断。关于如何才能判断某次事故是由睡眠引起的，录音中提到“There are some strong pointers”，引出下文具体例子。讲话者提到“If an accident involves only one vehicle…especially if there are no skid marks or other signs of braking”，对应选项B与C的内容。而A项与“…especially if it occurs where traffic is light and vehicles ale consequently well-spaced on the road”表达意思相符。由此可见，前三个选项的内容在录音中都有提及，因此该题正确答案为D。

    As for the writer, what can be concluded from the talk?
    A

    He believes driving on a road as dull as a motorway leads to drivers’ sleepiness.

    B

    He thinks it a pity that the issue of sleepiness has not been properly reported.

    C

    He agrees with the government bodies that reliable statistics cannot be obtained.

    D

    He shares with the police that sleepiness has caused 20％ of motorway accidents.


    正确答案： D
    解析：
    事实细节的找寻和判断。根据录音中提到的“Driving on a road as dull as motorway makes worse sleepiness in a driver who is already sleepy”（在沉闷的高速公路上开车使已经昏昏欲睡的司机感到更加的困倦），可知在说话者看来在沉闷的高速公路上开车是导致司机困倦的重要原因。因此A项内容与录音原文表达意思相一致。
    【录音原文】
    　　Sleep laboratories around the world are finding that an alarming number of drivers on motorways may be falling asleep at the wheel. Although researchers have difficulty in knowing for certain whether an accident has been caused by sleepiness, it appears that a driver who is on the road between 4 a. m. and 6 a. m. is about 10 times as likely to have a sleep-related accident as someone who is driving in the middle of the morning or early in the evening. Some British police forces have become sufficiently concerned to launch campaigns to alert the public to the danger. Major motor manufacturers such as Ford and Renault are investigating ways of incorporating sleepiness detectors and alarms into their vehicles.
    　　However, British government bodies responsible for road safety have not initiated any studies into the problem of sleepy drivers on motorways. The Department of Transport claims that it is “aware of the problems”, but does not regard it as a high-priority issue and is not planning to support any relevant research apart from a general study on “driver behaviour”.
    　　Unfortunately, the issue is clouded by the fact that many motorways accidents that might be caused by sleepiness are categorized under other headings, such as “inattention”, “failed to look or see other vehicle” and “misjudged speed/distance”. Figures collected in the 1970s by the Transport and Road Research Laboratory list the cause of 20 percent of all road accidents as “perceptual errors”. “Fatigue” was specified in only 2 percent of cases. However, few investigators inquire further to discover just why a driver was not attending, failed to look or made errors in perception. For various reasons, including the fear of prosecution and possible difficulties with insurance claims, drivers are reluctant to admit to falling asleep, but are more willing to admit to “inattention”. When these rather vague responses are examined thoroughly, sleepiness often emerges as the true culprit.
    　　Driving on a road as dull as on a motorway makes worse sleepiness in a driver who is already sleepy. But how can we tell if an accident on a motorway has been caused by sleepiness? There are some strong pointers. If an accident involves only one vehicle, which runs off the road into the central crash barrier, a tree or a bridge, then sleepiness is likely to be the cause, especially if there are no skid marks or other signs of braking. A driver who is alert to impending crash grips the steering wheel and suffers different injuries from someone who is asleep and holding the steering wheel loosely. This pattern of injury, combined with an absence of skid marks on the road, also suggests that the driver was asleep in accidents where one vehicle runs into the back of another, especially if it occurs where traffic is light and vehicles are consequently well-spaced on the road.
