  When a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Building would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would“radiate light”and“change color with the push of a button”. Food would be replaced by pills. School would be taught“by electrical impulse while we sleep”. Cars would have radar. Does this sound like the years 2000? Actually, the article was written in 1958 and the question was“What will life be like in 1978?”

  The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict(预言)accurately(准确地). By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in“airbuses”, large all-weather helicopters carrying up to 200 passengers, when a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents“almost unheard of”. Does that sound familiar? If the expert had been accurate it would be, because he was writing in 1957. His subject was “The City of 1982”.

  If the experts sometimes sound like high-school students, it's probably because future study is still a new field. But economic(经济的)predicting has been around for a long time. It should be accurate, and generally it is. But there have been some big mistakes in this field, too. In early 1929, most predictors saw an excellent future

for the stock market. In October of that year, the stock market had its worst losses ever.

  One predictor knew that predictions about the future would probably be wrong. In 1957, H.J. Rand of the Rand Corporation was asked about the year 2000,“Only one thing is certain,”he answered.“Children born today will have reached the age of43.”

(1)High-school students' answers to“What would life be in 1978?”sound ________.

[  ]

A. accurate
B. imaginative
C. correct
D. OK

(2)According to the writer, forecasting is fairly accurate in ________.

[  ]

A. politics
B. science
C. agriculture
D. economics

(3)Which of the following statements is NOT true according to the passage?

[  ]

A. Predictions are accurate.

B. Professionals sometimes sound like high school students.

C. There have been some big mistakes in the field of economic forecasting.

D. Predictions about the future will probably be wrong.

(4)The present passage was most probably written ________.

[  ]

A. just before 2000

B. in 1958

C. after 1982

D. in 1957

(5)H.J. Rand's prediction about the year 2000 shows that ________.

[  ]

A. it is easy to figure out in advance what will happen

B. it is difficult to figure out in advance what will happen

C. only experts can figure out in advance what will happen

D. very few experts can figure out in advance what will happen

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.carsB.groovesC.spaces between intervalsD.bulldozers
【小题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
【小题3】The underlined word “optimal” in the passage might mean        .
A.fastestB.possibleC.bestD.suitable
【小题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
【小题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
