I have a backpack. It is large and it is blue. It is a birthday gift from my parents. I love it very much. It is very hard-working, because I keep all my school things in it. It is very heavy. It is with all the time during school days. It is a good friend of mine.

　　我有一个背包，它非常大，是蓝色的，是我父母送给我的生日礼物，我非常喜欢它。这是非常辛苦的工作，因为我把我所有的学习用品都放里面，很重。上学的时候它要背着所有的东西，它是我的好朋友。
