The city we lived ，因为通篇都用的是一般现在时，所以这句的lived要改为live，

 It is no doubt that  这一句中， it 改为that

 City means more opportunity  这句 opportunity用复数

coloful 拼写错误

But meanwhile 这个没什么大的语法错误，不过一般不这么用，可以用however代替

 a lot of problem   这句    problem用复数

be a part of our city , be 改为as

Shanghai  2010 World Expo is a platform to show China to all over the world , 最好把all over 删掉

最后， better and better.应该说 more and more better

总的来说还是很不错的文章哦，加油！！
