Homework may  小题1:    boring for most students. But last Friday, students in my class 小题2: interesting and special homework to do. Our head teacher asked us 小题3: a letter to ourselves ten years in the future. How do you write to your future self ? Everyone was surprised and whispered about，“You can set a standard（标准）of life you are willing to live by. Maybe the letter小题4: in ten years." Our head teacher reminded us. My life  小题5: a lot since l was in Grade Nine. I think I am sure to do it well.
