¡¡¡¡Shanghai will host the 2010 World Expo. The World Expo has a long history but it has never been held in Asia. So the 2010 World Expo is an honor for all of the Asians. ()ur government has promised that it will be the best one. And Shanghai, as a host city, will have more chances to develop quickly.  As a student in Shanghai, I should learn English well so that I can be a volunteer in the Expo to help foreigners know more about Shanghai.
