We wake up very early to go to school， maybe even earlier to meet with a teacher， complete our extracurricular（课程以外的） activities， come home to have a quick dinner， talk for eight minutes with our parents and do homework until we fall asleep． But then we remember． We have to look at the American College Test（ACT） exercises one more time． Half asleep， we run downstairs to get the ACT book， and start studying． After this we finally get to turn off the lights and drift away to sleep． And then six hours later， we do it all over again．

In my health class， my teacher told us that teenagers need at least eight to nine hours of sleep each night． The sad truth is， with so much to do every day， high school students cannot keep to this sleep schedule（安排）．

Let me ask you all a question： Doesn't it seem more humane（人道的） to give a teenager perhaps two hours of homework each night？ This would allow us to have the eight to nine hours of much needed sleep． Or does it seem better to pile students with five hours of work a night？ It leaves us very little time to relax， therefore reducing the time that we can sleep．

In my opinion， the present structure（结构） of the junior year of high school doesn't work well． Junior year of high school is a time for growth． By this time many students have the ability to think creatively， and solve challenging problems． Homework is important for a student's growth． But do we really need to spend countless hours a night doing it？ Too much homework can only lead to too little sleep and too low an ability． I do think it is time to change the structure， so that we sleep at home， and learn at school．
