The average human spends 1/3 of his or her lifetime sleeping. Imagine how much people could accomplish if they spent less time sleeping. For many high school students, getting enough rest is not a priority (优先). A National Sleep Foundation survey shows that teens are staying up too late at night, usually getting 7 hours of sleep instead of the recommended 9 hours. Although teenagers' internal clocks (生物钟) are partially to blame for not sleeping earlier, many students lose sleep because of school.

Schools should allow students enough time for sleep, taking jobs, sports, and other extracurricular activities into consideration.

Students who are extremely busy and lose sleep as a result should not have to drop their activities in order to get more rest. With colleges becoming increasingly competitive, it is unreasonable for students to be forced to choose between sleeping and excelling.

In addition to interfering with academic success, lack of sleep also affects a person's safety. Almost 1/2 of the 100 000 annual sleep-related car accidents in the U. S. involve people between the ages of 15 and 24.

There are a number of solutions that high schools can choose from. One option is starting school at a later time. A later schedule is more appropriate for teenagers' biological clocks. Although it may create more expenses for the school, the change would be well worth it. Research has shown that students who get more sleep are happier, healthier, more productive, and earn higher grades than those who suffer from sleep deprivation免职, 撤职; 废止. Students who get enough sleep are also more attentive and less likely to fall asleep in class.

A second option is offering study hall as an elective选修课程. Since this gives students time to do homework or take a nap, it creates more free time after school.

A third alternative可供选择的办法 is for some teachers to alter(改变) their teaching methods a bit by giving only important, necessary homework. Quite a few teachers assign busy work, which doesn't teach students much but instead wastes their time. It is also helpful if teachers communicate with each other to plan out their test schedules.

High schools should not negatively interfere with the amount of sleep teenagers get. Instead, schools should take steps to benefit the lives of students by allowing them enough time to rest. As Fran Lebowitz said, “Life is something to do when you can't get to sleep.”
