写作记忆Season: there are four seasons in the year round, spring, summer, autumn, winter. I like summer best. It usually lasted from may to august. The weather in summer is always very hot. We needn’t to wear to much clothes.and  we can go to swimming in the river. but sometimes it often rained. The trees and grass turn green, the plants grow fast in summer. Some flowers are come out. It’s very beautiful.
