【答案】We can now have enough sleep About a month ago， most Chinese students got less than 8 hours of sleep each night. They had too much homework and would often stay up late to do it. In addition， they also had to get up early to go to school.But now in many cities， the schools make it a rule that students don't have to come to school until 8 a. m. according to a new rule. Those cities have also cut down the amount of homework assigned to each student. It's good for students' health.
Of course， students still have to use their time effectively. For example， after doing homework ， they will still read and help with the chores and take part in other activities.
