Humans have always dreamed of finding a way to leave traffic jams(交通堵塞)behind．Well, dream no longer．The flying car and pod car(豆莢車)can help cut down on traffic jams．

　　The world’s“first flying car”, called the Terrafugia Transition, has made its first flight in the skies of the US．It can fly 640 km through the air without adding more gas, the car maker, Terrafugia Inc, says．

　　As a light airplane, it is not easy for the Terrafugia Transition to fly in poor weather．However, it has the advantage of being able to continue the journey by road if conditions take a turn for the worse．

　　This is the first proven flying car with foldable wings．These allow it to perfectly transfer from air to road．

　　However, there are a few problems．The car/plane, which is expected to go on sale as early as 2011, will cost about ＄194, 000(1.33 million yuan)．Drivers will also need a driver’s and pilot’s license．

　　For those afraid of heights, or who don’t want to fly, the pod car is a great way to travel．Imagine using a button to stop the small pod-shape car．The doors open, you climb into the passenger seat, and enter your personal number．Minutes later, the doors slide open and you have reached the place where you’re going．

　　Cities around the world are looking into pod-car systems, as pod cars do not need human drivers．They are designed for one person or small groups traveling together．Passengers simply type their place into the pod car’s computer and the pod car takes them directly there．

　　Because pod cars do not make unnecessary stops and use electricity, they save a lot of energy and do not pollute the air．Pod cars also provide passengers with faster service and more privacy than a subway or bus．

　　While flying cars and pod cars may be a dream available to a few, many humans are still dreaming bigger dreams, such as teleportation(瞬間位移術(shù))．It is most widely found in works of science fiction．

　Telep ortation is a method of transportation, in which, objects or information are dematerialized(使消失), and then recreated in another place．Maybe one day, teleportation could become a reality and people could avoid traffic jams for ever!

　　A team of scientists from Ohio State University did experiments on 33 volunteers who were getting better from heart disease following operation．They found that people who exercised while listening to Italian musician Antonio Vivaldi’s “The Four Seasons” did much better on language ability tests than without music．

　　“Facts suggest that exercise improve the leaning ability of people with heart disease,” said the psychologist Charles Emery, who led the study．“And listening to music is thought to enhance understanding．We just wanted to put the two results together,” he added．

　　The volunteers said they felt better emotionally and physically after working out with or without the music．But their improvement on the test doubled after listening to music during exercise．Scientists have proved that music can be good for health, education and well-being．It helps reduce stress, sadness and nervousness, encourage relaxation or sleep; wakes up the body and improve memory and thought．

　　In medical fields, music is used widely for patients who have had head hurts before and after operation．“The Four Seasons” was used because of its moderate tempo(舒緩的節(jié)拍)and positive results in earlier research．“ Exercise seems to cause positive changes in the nervous system(神經(jīng)系統(tǒng))and these changes may have a direct result on learning ability,” Emery said．

　　Scientists have been studying the results of music on understanding since the early 1950s．By 1990, psychologists were using Mozart’s music, especially his violin pieces, to help children with speech disorders．Mozart’s was chosen because his music is not over-exciting and has clear structures．A study showed students who listened to Mozart went to score higher marks in an intelligence test．With important exams drawing near, your parents will not probably allow you to listen to music．But now you have good reasons to argue with them．
