求一篇介绍北京的英文演讲稿（高中英语水平）

Beijing is an ancient city with a long history.Back in 3000 years ago in Zhou dynasty,Beijing,which was called Ji at the moment,had been named capital of Yan.Thereafter,Liao,Jin,Yuan,Ming and Qing dynasty all made Beijing their capital.Therefore,Beijing was famous for "Capital of a thousand years".
The long history leaves Beijing precious cultural treasure.Winding for several kilometers in Beijing area,the Great Wall is the only man-made structure that could been seen in the space.The Summer Palace is a classic composition of ancient royal gardens,and the Forbidden City is the largest royal palaces in the world.Tiantan is where the emperor used to fete their ancestors,and also the soul of Chinese ancient constructions.The four sites above has been confirmed world cultural heritage by UNESCO.However,the best representatives for Beijing are the vanishing Hutongs and square courtyards.Through hundreds of years,they have become symbol of Beijing's life.Tian'anmen square being still brilliant today with cloverleaf junctions and skyscrapers everywhere,the old-timey scene and modern culture are combined to present a brand new visage of Beijing.
As Beijing has been confirmed home city of Olympics 2008,the spirit of "green Olympics,scientific Olympics and humanized Olympic" will surely bring more and more changes to Beijing,promote the development of sports and Olympics in China as well as in the world,and strengthen the friendly communications between Chinese and foreign people.
