Xi'an holds the International Horticultural Exposition, 2011. The International Horticultural Exposition(世園會)  has a long history and it'll show us the beauty of the nature. So the International Horticultural
Exposition is an honor for all of the Xi'an people. Our government has
promised that it will be the best one. And Xi'an, as a host city, had more chances to develop quickly. As
a student in Xi'an, I should learn English well so that I can be a volunteer in the exposition to help foreigners know more about Xi'an.
    The Expo emblem(徽章)  looks like the famous City Wall. The Expo is based on a general pattern of "
two circles,  two axes,  and five clusters. . . " Xi'an Horticultural Expo was held from April to October,
2011.
    Great changes have taken place in Xi'an and more and more people throughout the world are focusing
their attention on Xi'an now.  As a citizen of Xi'an, I must spare no efforts to do what I should do. First, I
decide to plant more trees to make our city more beautiful.  Second, I should obey seven nos and be good at learning from others.Third,I should study hard so that I can do something better for my city in the future.
