A Train Floating On Air

  A train that floats on air? It's not magic-it's magnets(磁).And it's close to reality.

  In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus.In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power.And in China, a magnet train line linked Shanghai with nearby Pudong Airport.

  These trains use magnetic levitation(悬浮)technology, “maglev” for short.They use the same rules as the magnets you pick up at home or school:opposite poles of magnets attract each other, and like poles repel each other.

  How does it work?

  Powerful magnets on the bottom of train repel magnets on the track, which is actually just a magnet-filled guiding way.With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past.

  When an electrical current is sent through the track, the train moves.Turn the current backwards and the train slows down.

  Maglev doesn't rely on the friction(摩擦力)of wheels on track, so it can climb a much steeper hill than a traditional train.And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop.

 World Expo 2010 Shanghai China is to be staged in Shanghai from May 1 to October 31, 2010. If you plan to visit the Shanghai Expo this summer, China Pavilion(馆)is a must - see area for you.

China Pavilion, which is called Oriental Crown, is located at the center of the Expo site. Standing 63 meters tall, the China Pavilion takes the shape of an emperor's crown, with the upper layers larger than the lower ones. Covering 160,000 square meters in floor space, the pavilion is made up of a national hall and a regional(宗教的  ) hall. Buildings on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put for­ward by Chinese from around the world. The pavilion has both traditional and modern features, which helps devel­op the theme of the 2010 Expo; "Better City, Better Life. For example, it is red in appearance, which covers the  traditional Chinese culture, and it is green indoors, with the use of energy - saving techniques. The Shanghai World Expo is expected to attract 70 million visitors from across the globe. It is estimated that 400,000 people will visit the Expo and its 140 pavilions every day during the period, but the China Pavilion is only able to receive about one tenth of the total. How to hold so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent(长久的) landmark.

During the Expo, the main structure(结构  ) will be used for an exhibition based on the theme of “ Chinese wisdom in urban (城市)development” by explaining the values of harmony(和谐  ), nature and spirit. The three - story pavilion has three sections. The top floor's “Footprint of the East” will show some of the changes in Chinese cities. There, you can see a film which shows how Chinese cities have changed, especially in the past 30 years. According to Lu Chuan, director of the film, the scenery is like something from Lord of the Rings. On the second floor, “Journey of Wisdom” will explain China's four great inventions.  And the ground's “ Blossoming” City will display scenes from cities of the future.
