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.”

A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.
The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.
An addiction that doesn’t discriminate(歧视)
“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.
Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.
Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.
In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.
“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.
