　　In North America, most students go to school by bus．The subway is also widely used in some cities．In small towns and cities, walking is still popular．

　　The yellow school bus is a familiar sight all over North America．It is a very convenient (方便的) form of transportation (运输)because it takes students right to the entrance(人口)to the school．It also gives students opportunity (机会)to chat with their friends．However, the bus is slow and does not always pick up on time．

　　The subway is a means of getting around quickly in many cities．However, it is expensive(贵的)and can be very crowded during rush hour(高峰时间)．Another disadvantage of the subway is that the stops are not so close to the school, and students often have to walk considerable distance or take a bus from the subway stop to the school．

　　Walking has a number of advantages (优点)for those who live reasonable close to school．It's free and it provides(提供)a form of exercise．However, it's no fun if you have a large backpack full of books to carry．It's also unpleasant if the weather is either too hot or too cold or wet．

　　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(豆荚车)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(瞬间位移术)．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!
