Question

【题目】C

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 efect, making you almost car-sick.”

【1】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

【2】The underlined word “optimal” in the passage might mean ________.

A. fastest B. possible C. best D. slowest

【3】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

【4】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 Japan

Answer 1

【答案】

【1】A

【2】C

【3】D

【4】B

【解析】

【语篇解读】本文是一篇说明文。作者介绍了日本的音乐路面。人们开车行驶在该路面上就可听到音乐，声音的高低取决于凹槽的间距，车速影响音乐的效果。

【1】细节理解题。由文章第四段内容“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.”可知，曲子的高低 取决于凹槽间的距离，故选A项。

【2】词义猜测题。结合文章倒数第二段，并联系上下文可以推断，optimal应表示“最佳的，最理想 的”，选C 。

【3】细节理解题。由文章最后一段首句“You need to keep the car windows closed to hear well”可知， 为了很好地听曲子需要将车窗关闭，故选D项。

【4】主旨大意题。本文讲述的是日本发明音乐路面的事情，故选B项。
