题目内容
14.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."
28.We can learn from the passage that the highness of notes is depended on.A
A.how far the grooves are
B.how big the grooves are
C.the number of the grooves
D.the speed of the car
29.The underlined word"optimal"in the passage might meanC
A.fastest B.possible C.best D.slowest
30.In order to hear the music well,you have toD
A.drive very fast
B.drive slowly
C.open the windows wide
D.keep the windows closed
31.What's the best title of the passage?B
A.A New Type of Music
B.Melody Roads in Japan
C.A Musical Road Surface
D.A New Invention in Japan.
分析 日本发明音乐路面,声音的高低取决于凹槽的间距,车速影响音乐的效果.
解答 28.A 细节理解题.根据句子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,声音的高低取决于凹槽的间距,因此正确答案为A.
29.C 细节理解题.根据文章倒数第二段The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound.旋律之路的最佳速度是44kph,但人们说这是不容易得到想要的声音.,并联系上下文可以推断,optimal在这里是"最佳的,最理想的",因此正确答案为
30.D 细节理解题.根据文章最后一段第一句话You need to keep the car windows closed to hear well,你需要保持车窗关闭听好了,可以得出选项D正确.其余三项都与原文说法不符.
31.B 标题归纳题.文章讲述的是日本发明音乐路面的事情,所以B选项符合题目.
