Teacher and classmates, because I can't hand in the homework on time so to stand here to reflect on their own. Layout of history homework yesterday, I finish it on time, but this morning I went to school late, so the homework in a hurry, temporarily be negligent, forget the history homework to the back of the historical leader. I be negligent behavior can delay the leader collect, teacher assignments, also let their work could not let the teacher to change and correction. This is the one I shouldn't have made mistakes, but I have made, only that I was too careless. I will carefully check the homework, to school early, so as not to hurry, can avoid missed homework situation. I am here to teacher students solemnly say sorry, and that, I won't make that mistake, hope the teacher students can give me a chance! Thank you.
