When their parents were children, they imagined a future standing in front of a class of pupils or doing the rounds （巡诊） as a doctor．

     But today’s British teenagers, a survey suggests, seem to have set their sights only on becoming the next Leona Lewis or Wayne Rooney．

     Researchers questioned 3,000 teenagers about their ambitions （strong desire to achieve sth．） and also asked parents about their youthful career hopes．

     According to the survey, youngsters dream of a celebrity （明星） lifestyle, perhaps after finding fame through shows such as the X Factor, and of being actors or sports stars．

     Copying the likes of Rooney and David Beckham was the top career ambition of today’s teenagers, cited （说到） by 12 percent．

     Almost as many, 11 percent, wanted to be pop stars, and the same proportion （比例） dreamed of being actors．

     The success of celebrity chefs such as Jamie Oliver and Gordon Ramsay is likely to explain why becoming a chef is now the dream of 5 percent, a career ambition which did not figure in the list of 25 years ago．

     A quarter of a century back teaching was the top career choice, cited by 15 percent． These days the job is chosen by only 4 percent．

     Of the traditional professions （职业）, only law has risen in popularity．

     The survey also suggests that more girls dream of becoming doctors and boys want careers as astronauts or firefighters．

     Child psychologist Laverne Antrobus said the findings reflect（反映）today's celebrity culture and warned children against unrealistic dreams．

     “Children see footballers, pop stars and actors on TV and their lives look exciting, glamorous （光鲜的） and fun,” she said． “It is hard for them to realize that they are the end product of a lot of ingredients including talent, determination and years of hard work． Wayne Rooney is not on the pitch （球场） by chance．”

     As Antrobus pointed out, there is absolutely nothing wrong with children having big dreams, but “these have to be based on reality,” she said．

“We don’t have rush hours any more”, said Mr. Charles Mac Lean, who runs the nation’s busiest road．“We have rush periods, and they keep getting longer and longer．”

Mac Lean was describing Chicago’s 235 miles of expressway． But the same might be said about almost any of the expressways that have become an important part of American city life—and about the heavy traffic that often blocks them．In Chicago, a computerized system has been developed that controls traffic on the city’s seven expressways．Now one man—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights． The system uses electronic sensors that are built into each expressway, half a mile apart．Several times a second, the computer receives information from each sensor and translates it into green, yellow, or red lights on a map in the control room．A green light means the traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour and red means heavy  traffic—cars standing still or moving less than thirty miles an hour．

“See that red light near Austin Avenue?” the controller asked a visitor．“That’s a repair truck fixing the road, and the traffic has to go around it”．

At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again．“A lot of trucks get on the expressway there,” the controller explained． “They can’t speed up as fast as cars．”

The sensors show immediately where an accident or a stopped car is blocking traffic, and a truck is sent by radio to clear the road．The system has lowered the number of accidents by 18 percent． There are now 1．4 deaths on Chicago’s expressways for each one hundred million miles traveled, while in other parts of the country there are 26．

Traffic experts say that the Chicago system is the “coming thing”．Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston．“Chicago has taken the lead,” says New York City’s traffic director; and he adds, “We are far behind…”
