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(音叉)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.
Patent documents for the design describe it as notches(刻痕)"formed in a road surface so as to
play a melody without producing simple sound or rhythm and reproduce melodylike 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(推土机)before driving over them and found that they helped
to produce all kinds of tones.
The optimal speed for melody road is 44 kph, 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 12 mph[20 km/h]has a slowmotion
effect, making you almost carsick."

The magician (魔术师) usually depends on his skill with his hands, and on his knowledge of psychology (心理学). Since magic tricks are meant to fool people, the use of psychology is important. The magician must keep people from noticing all the movement of his hands and from thinking about the secret parts of his equipment. He must also lead the people to draw false conclusions. The magician’s success depend on the fact that many things seen by the eye do not register (记下) on the mind.
Two basic magic tricks are making objects seem to appear or to disappear. For example, the magician puts a small ball under one of several cups. The ball then seems to jump from one cup to another or to change color. What actually happens is that the magician, by quick hand movements, hides one ball. While doing this he talks to the people and waves a brightly colored cloth with one hand. The people are too busy watching the cloth and listening to the magician’s words to notice that his other hand is hiding the ball.
Another favorite trick is to cut or burn something, and then make it appear again. What actually happens is that the magician makes the cut or burned object disappear by quickly hiding it while the people watch something else. Then he “magically” makes it appear again by displaying another object that has not been cut or burned.
