On the road motorists should be aware of cyclists and be ___

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.” 小题1:According to the passage, melody roads use to create different notes. A．cars B．grooves C．spaces between intervals D．bulldozers 小题2:We can learn from the passage that the highness of notes is depended on . A．how far the grooves are B．how big the grooves are C．the number of the grooves D．the speed of the car 小题3:The underlined word “optimal” in the passage might mean . A．fastest B．possible C．best D．suitable 小题4:In order to hear the music well, you have to . A．drive very fast B．drive slowly C．open the windows wide D．keep the windows closed 小题5:What’s the best title of the passage? A．A New Type of Music B．Melody Roads in Japan C．A Musical Road Surface D．A New Invention in J

The chief problem in coping with foreign motorists is not so much remembering that they are different from yourself,but that they are enormously variable.Cross a frontier without adjusting and you can be in deep trouble.
One of the greatest gulfs separating the driving nations is the Atlantic Ocean.More precisely,it is the mental distance between the European and the American motorist,particularly the South American motorist.Compare,for example,an English driver at a set of traffic lights with a Brazilian.
Very rarely will an Englishman try to anticipate the green light by moving off prematurely.You will find the occasional sharpie who watches for the amber to come up on the adjacent set of lights.However,he will not go until he receives the lawful signal.Brazilians view the thing quite differently.If,in fact,they see traffic lights at all,they regard them as a kind of roadside decoration.
The natives of North America are much more disciplined.They demonstrate this in their addiction to driving in one lane and sticking to it — even if it means settling behind some great truck for many miles.
To prevent other drivers from falling into reckless ways,American motorists try always to stay close behind the vehicle in front which can make it impossible,when all the vehicles are moving at about 55 mph,to make a real lane change.European visitors are constantly falling into this trap.They return to the Old World still flapping their arms in frustration because while driving in the State in their car they kept failing to get off the highway when they wanted to and were swept along to the next city.
However,one nation above all others lives scrupulously by its traffic regulations — the Swiss.In Switzerland,if you were simply to anticipate a traffic light,the chances are that the motorist behind you would take your number and report you to the police.What is more,the police would visit you; and you would be convicted.The Swiss take their rules of the road so seriously that a diver can be ordered to appear in court and charged for speeding on hearsay alone,and very likely found guilty.There are slight regional variations among the French,German and Italian speaking areas,but it is generally safe to assume that any car bearing a CH sticker will be driven with a high degree of discipline.
