Homework is an important part of going to school:       But too much homework may trouble you.
First, be sure you understand the assignment(任务). Write it down in your notebook if you need to, and don’t be afraid to ask questions about what’s expected. 
Second, use any extra time you have in school to work on your homework.       It’s wonderful to hang out with friends during free time, but the more work you can get done in school, the less you’ll have to do that night.
Third, pace yourself(自我调节). If you don’t finish your homework during school, think about how much you have left and what else is going on that day, and then budget(安排) your time.
