求翻译：The tutors often help the chlidren with the subjects that the student have studied that day . If you can listen to the teacher carefully in school, you don't have to waste the time after school. So i think the tutors are not very helpful. Students should have good habits in school so that their parents dong't have to waste the money to find a tutor . But you don't have a good habit,the tutor can help you reviw the subject. They are useful in the other hand.是什么意思？
