It’ s a time when school, homework, active social lives and part-time jobs keep teenagers(青少年)busy from early in the morning until late at night. They are likely to try to make up for a lack of sleep by "sleeping in" on the weekends. Unfortunately, this causes irregular sleep and actually makes the problem worse.
Most teenagers are not able to fall asleep until late at night. Since many teens aren’ t sleepy until around 11 p. m., but need to be at school by 7: 30 or 8: 00 a. m., they cannot get enough sleep. During puberty(青春期), the biological clock in the brain naturally re-sets to a later time, and this causes teens to fall asleep later. Then, when it’ s time to get up, a teen’ s body clock is likely to still be producing the night-time hormones(荷尔蒙). This makes it hard for them to feel active and energetic in the morning.
A growing body of research suggests that starting high school later improves attendance, achievements and grades. A few years ago in an important study, test scores on the SAT college entrance exams in Edina, Minnesota jumped more than 100 points on average, when the morning school bell rang an hour later. Unfortunately, most schools are not set up to start later and fail to satisfy teen’ s sleep needs.
The study in Minnesota shows that starting morning school one hour later helps to______.
选项
A、make teenagers grow faster
B、change teenagers’ sleep needs
C、do more research on teenagers
D、improve students’ achievements
答案
D
解析
细节题。题干意为“明尼苏达州的研究表明,早间上课时间推迟一个小时有助于______。”原文最后一段提到,该地区SAT大学入学考试平均成绩提高(jump)了100多分,由此可见,D选项“提高学生成绩”是正确答案。另外三个选项“促进青少年成长”、“改变青少年睡眠需求”、“针对青少年做更多的研究”在原文中都未曾提及。故D正确。
