Shanghai Expo Brings Me A Lot
A very good morning/afternoon/evening to you all,everybody.As is known to us,the year 2010 saw China's first time to host the Expo in Shanghai,which attracted the world's all attention..Over 200 pavillions of different countries and areas throught out the world poured by the Huangpu River,the mother river of Shanghai,which is the biggest and most developed city in China.Undoubtedly,It was a good opportunity for China to display itself and push forwads its economy,letting the world knows more about China as well as China knows more about the world.Most importantly,I had the pleasure to work for it as a volunteer.I have achieved a lot and made a number of foreign friends during the Expo.
Involving more countries and peope,the Shanghai Expo has made itself the greatest one in its history,marking that China is certaily playing a more and more important character in the world stage,of which I am proud.Meanwhile,the world has changed a lot,with new technology used and new products seen.We are a happiest generation,livling in a fully-new world,without hardship or trouble
Friends,do you think we have the reason for not studying hard?Surely not.On the contrary,we must!We must do something for our country,for our world.We must make every efford to make them more beautiful.
That's all.Thank you.
