| In 1896, the first modern Olympic Games were held in Athens, Greece. Since then many countries have held Olympics, such as England, France, Germany, Canada, the USA, Spain and Australia. After more than a century the Games return to the hometown in 2004. When people hold the Olympic Games, they always make an emblem (会徽). The emblem of the Athens Olympic Games in 2004 is a white olive branches in the sky. Athens developed a spirit of peace. An officer said, "While in Athens, the world should be at peace." We hope the peace is not just for a short time. We would like the message from the Athens Games to help countries come together and solve their problems. In 2008 the Olympic Games have been held in China. And China has already made a seal as the emblem of the Beijing 2008 Olympic Games. The emblem has a single Chinese character on a red seal and means "Chinese seal-dancing Beijing". Below it, there are the words "Beijing 2008". The character in the emblem is "Jing". It means "Capital" of China and it is also like a runner or a dancer. The running figure (人形) of the emblem shows the spirit of the Olympics-faster, higher and stronger. |
