假设你是李华,根据你校美化校园的规划用英语给你在英国的笔友写一封信

Since the 2010 World Expo is around the corner,the Shanghai government is busy preparing for it and out city has taken on a new look。First and foremost,as we all know,many beautiful and creative pavilions of different countries have been built for the exhibition in the Expo site along the Huangpu River。Besides,the government also pays great attention to the improvement of public transportation。We citizens can find that many roads have been widened and several new metro lines are being built now。Furthermore,the common people of all ages are keen on learning English and even took some foreign language courses,hoping to be a volunteer for the World Expo。There is no doubt that we have made great achievements,but these are still not enough。For example,first,in my point of view,as the host,we Shanghainese ought to be better informed of the related knowledge of the Expo in order to help foreign visitors。Moreover,some citizens’ spiritual quality is far from satisfactory so that they sometimes disobey “7 Don’ts”。In short,holding a successful world Expo needs our joint effort。As the theme of Expo 2010 said,"Better City,Better Life," it represents the common wish of the whole humankind for a better living in future urban environments。
