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.”

1.According to the passage, melody roads use        to create different notes.

2.We can learn from the passage that the highness of notes is depended on        .

3.The underlined word “optimal” in the passage might mean        .

4.In order to hear the music well, you have to        .

5.What’s the best title of the passage?

Art museums are places where people can learn about various cultures．The increasingly popular "design museums" that are opening today, however, perform quite a different  1  .Unlike most art museums, the design museum shows objects that are easily found by the general public．These museums sometimes even place things like fridges and washing machines in the _2  of the hall．

People have argued that design museums are often made use of as advertisements for new industrial technology．But their role is not simply a matter of sales—It is the   3   of excellently invented products．The difference between the window of a department store and the showcase in a design museum is that the first tries to sell you something, while the second tells you the success of a sale．

One advantage of design museums is that they are places where people feel   4   with the exhibits．Unlike the average art museum visitors, design museum visitors seldom feel   5   or puzzled．This is partly because design museums clearly show how and why mass-produced products work, and how design has   6   the quality of our lives．Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something beyond their __7__．

In recent years, several new design museums have opened their doors．Each of these museums has tried to   8   the public's growing interest in the field with new ideas．London's Design Museum, for example, shows a collection of mass-produced objects from Zippo lighters to electric typewriters to a group of Italian fish-tins．The choices open to design museums seem far less  _9  than those to art museums．
