Summertime is the besttime of the year.There is no school for monthsI get to do what I want.With no tests no homework,I'm as free as a bird.　　I do many things during the summer vacation.I relax by reading books watching TV.I also hang out with my friends travel with my family.However,I don't play in summer.I take advantage of the free time to learn more.For example,last summer I learned to swim.This summer I might study computers or English
