My family I have a family.There are five people in my family.There are my mother,my father,my sister,my brother and I.My father is 39 years old.He is of medium build (build -->size) and medium height.He is a little strict (你想表达严肃呢,就strict -->serious; 你想表达对我们要求严格呢,就strict -->strict with us) .My mother is 35 years old.She has long hair and is of medium height.My sister is little.She is (加个only在这里较好,前后更呼应) 2 years old.She is very cute.My brother is small (small -->young) .He is 10 years old.He has short black hair and is of medium build (build -->size). I have a happy family! (个人觉得最后一句改为What a happy family I have!更好结尾．你写的好像才刚开始,还没讲完一样．） 写得不错,修改只是个人意见,随你而改!
