In the past,students spend fourteen hours staying school and students have to do hamework about two hours.So students only can six hours sleep.Andin the weekend or holiday,students have to have extra classes.Howeve,students had some activities,but they were boring and few.
But now have great changes.Students spent 7 hours staying and spend more than I hour doing homework.Students don't have extra classes and have colorful activities after class.
I think this scheme is right.Do you think so？
