1、There are four seasons in a year．They are spring，summer，fall and winter．It's warm in spring．Trees and grasses turn green．I like flying kites with my friends．It's hot in summer and it often rains．I like to go swimming in the river．Fall is a cool season．Sometimes I help the farmers pick apples．It's cold in winter and it sometimes snows here．I like to ski and skate．
