Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of“melody roads,”which use cars as tuning forks to play music as they travel.
The concept works by using grooves(凹槽).They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Paten documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”.
There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound.
“You need to keep the car windows closed to hear well,”wrote one Japanese blogger.“Driving too fast will sound like playing fast forward, while driving around 12mph[20km/h]has a slow-motion effect, making you almost car-sick.”
【小題1】According to the passage, melody roads use        to create different notes.

A.carsB.groovesC.spaces between intervalsD.bulldozers
【小題2】We can learn from the passage that the highness of notes is depended on        .
A.how far the grooves areB.how big the grooves are
C.the number of the groovesD.the speed of the car
【小題3】The underlined word “optimal” in the passage might mean        .
A.fastestB.possibleC.bestD.suitable
【小題4】In order to hear the music well, you have to        .
A.drive very fastB.drive slowly
C.open the windows wideD.keep the windows closed
【小題5】What’s the best title of the passage?
A.A New Type of MusicB.Melody Roads in Japan
C.A Musical Road SurfaceD.A New Invention in J

So I carried on and found the bus stop, which was a request stop, where the bus wouldn’t stop  42  passengers wanted to get on or off.

Generally in this situation, because I hated  43   I was blind by asking for help, I tried to guess at the sound. Sometimes I would  44  a big lorry and stand there feeling stupid as it drew away. In the end, I usually managed to  45  my pride and ask someone at the stop for help.

科目:高中英語 來源:2012-2013學年江蘇省揚州中學高一5月月考英語卷(帶解析) 題型:閱讀理解

Motorists over the age of 75 face compulsory tests of their eyesight and ability to drive under proposals being considered by ministers.
The biggest overhaul of motoring law in a generation could also lead to all drivers having to give assurances(保證)of their fitness to get behind the wheel every 10 years.
Other changes under consideration include issuing(發放)daylight driving licenses for motorists with night blindness, together with stricter checks on all drivers whose medical condition brought a threat to other road users.
It is understood that the proposals will be part of a review of the law governing the medical fitness of drivers that will be announced publicly by the summer.
The Driver and Vehicle Licensing Agency is dealing with a rising number of motorists who are concerned that they have conditions---from failing eyesight to epilepsy---that could affect their driving.
In 2006, the DVLA dealt with 600,000 motorists whose physical ability to drive needed to be recertified(重新認證), a 20 per cent rise on the previous year. With an ageing population, the biggest challenge is dealing with the rising number of elderly motorists. By 2021, there will be an estimated three million drivers over the age of 70 on Britain’s roads.
Drivers must renew their licenses at the age of 70 and every three years thereafter. The applicant is legally required to tell the DVLA of any conditions that could weaken their ability behind the wheel.
Ministers have ruled out a compulsory maximum age for driving but will instead rely on tightening up the checks on motorists over the age of 75. The most likely option would be tests to ensure motorists were fit to drive. They would include an eyesight test and a cognitive(認知) test that would prove a driver's ability to react to road signs, driving conditions, pedestrians and vehicles.
However, checks are likely to be tightened at all ages. The strictest controls are expected to be imposed(強制) on motorists of any age who have had a heart attack or stroke. They could have to produce a doctor's approval to resume(重新得到)driving. Anyone making a false declaration would be guilty of a criminal offence.
【小題1】Which of the following statements is TRUE according to the passage?

A.The new motoring law will come into effect by the summer.
B.Drivers over the age of 75 must renew their licenses every three years.
C.Doctors will decide whether one can get their driving licenses.
D.Drivers at all ages will be expected to provide their medical condition.
【小題2】What is the biggest challenge to the traffic safety in Britain according to the writer?
A.Ageing population. B.Increasing number of cars.
C.Increasing number of elderly motorists.D.Driving conditions.
【小題3】The underlined word “overhaul” in Paragraph 2 means _______.
A.changeB.considerationC.concernD.challenge
【小題4】What can be learned from the passage?
A.There will be more and more aged drivers in Britain.
B.Anyone can get a driving license as long as he/she is in good health.
C.Health tends to decline as one gets old
D.It will be guilty to make a false declaration.

D
Stricter Traffic Law can Prevent Accidents
From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of men, women and children on the roads. Man versus the motor-car! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.
It has been rightly said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They swear, they are ill-mannered and aggressive, willful as two-years-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles so benignly on the motorist and seems to condone his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy tragic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.
It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through stringent annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person’s driving ability. Present drinking and driving laws (where they exist) should be mad much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as too severe if tit results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.
52. The main idea of this passage is__________-
A. Traffic accidents are mainly caused by motorists.
B. Thousands of people the world over are killed each year.
C. The laws of some countries about driving are too lax.
D. Only stricter traffic laws can prevent accidents.
53. What does the author think of society toward motorists?
A. Society smiles on the motorists.
B. Huge car parks are built in the cities and towns.
C. Victims of accidents are nothing.
D. Society condones their rude driving.
54. Why does the author say:’ his car becomes the extension of his personality?’
A. Driving can show his real self.
B. Driving can show the other part of his personality.
C. Driving can bring out his character.
D. His car embodies his temper.
55.  Which of the followings is NOT mentioned as a way against traffic accidents?
A. Build more highways.
B. Stricter driving tests.
C. Test drivers every three years.
D. raise age limit and lay down safety specifications.
56.   The attitude of the author is
A. ironical     B. critical              C. appealing          D. positive
