My hometown is a pretty city,so people there are kind and polite.With coming of spring,grass and trees turn green,and flowers grew in many colors.In summer,the sea under the blue skies is even more beautiful.After autumn arrives,the city looks as an old man with leaves fallen from the trees.In winter,a lot of white birds come to my city for food.I can wait more patiently above the sea for quite a longtime.While they find fish come to the surface,they fly down immediate and catch them without delay.That is my city,and I love it so much.
