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 .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 _ 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." 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

There's a case to be made, from things like Google search figures, that Robert Frost's poem The Road Not Taken - you know, the one about two paths diverging in a wood - is the most popular in modern history. Yet people still can't agree what it means. On the surface, it's a fridge-magnet cliche on the importance of taking risks and choosing the road less travelled. But many argue it slyly mocks that American belief in the individual's power to determine his or her future. After all, the poet admits that both paths look roughly similarly well-travelled. And how could he be sure he took the right one? He'll never know where the other leads. Looking back at our life histories, we tell ourselves we faced important dilemmas and chose wisely. But maybe only because it's too awful to admit we're stumbling mapless among the trees, or that our choices don't make much difference. Two psychologists, Karalyn Enz and Jennifer Talarico, throw light on these matters in a new study with a title that nods to Frost: Forks In The Road. They sought to clarify how people think about "turning points" versus "transitions" in life. A turning point, by their definition, is a moment that changes your future - deciding to leave a job or marriage, say - but often isn't visible from the outside, at least at first. "Transitions" involve big external changes: going to university, marrying, emigrating . Sometimes the two go together, as when you move to a new place and realize it's where you belong. ("New Yorkers are born all over the country," Delia Ephron said, "and then they come to New York and it hits them: oh, that's who I am.") But it's turning points we remember as most significant, Enz and Talarico conclude, whether or not they also involve transitions. The distinction is useful: it underlines how the most outwardly obvious life changes aren't always those with the biggest impact. Hence the famous "focusing illusion", which describes how we exaggerate the importance of a single factor on happiness: you switch jobs, or... What's the best title of the passage? A) Is our fate in our own hands? B) Must people make changes in life? C) Should we choose the road less travelled? D) Are turning points connected with transitions?

Up to 56.5 percent of interviewees quite often download music, and 53.5 percent get entertainment messages from the internet. Yet the survey found that television is still the dominant mass medium. Seventy-nine percent of interviewees choose to watch TV to get information, and another 75 percent take newspapers as important as TV. Five major web sites in the Chinese language, namely Sina, Sohu, Netease, Baidu and Yahoo are still ranked top ones by web users, and those that voted for Sina as the best among them were 30.9 percent. Authorized statistics showed that web users in China have already 100 million, second to that of the United States. The survey shows that _ . A) Only 10.4% reported use the internet to send and receive email. B) Less than half of the people use the internet for enter fain-ment. C) All of the people reported like to play games on-line.
