Among the four seasons in a year, summer is my favorite, that makes me free, excited and energy. When summer vacation came every year, we can do all that we can’t do during our school time, go shopping with friends, swimming in warm water and even hiking and camping in the deep valleys. These activities lead me to enjoy full free. We can find us in an exciting world every day, with the sun shining bright, trees growing better and flowers coming out of with all kinds of colors. Summer makes me full of energy and we feel I have the strength to do most difficult things in my life. I like summer better, and what about you?
