Teacher, I am seriously behind. I will study hard and listen carefully in class in the future. I summed it up. What is the reason for my failure this time? 1. carelessness.
2. Don't listen carefully in class! absent-minded
3. Don't do your homework seriously! When I get home, I watch TV and play computer.
I don't know the importance of studying, just playing.
Teacher, I won't do so badly in the exam again
