第二节读写任务 (共1小题,满分25分)

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

Most high schools begin their day around 7:00 a.m., which leaves many teenagers nodding off in the morning. In fact, at least 20 percent of high school students fall asleep in class on a typical day. The problem: Teenagers need a lot of sleep-about nine hours each night, experts say. And most of them aren’t getting enough.

To help sleepy teens, some school districts of USA have tried delaying the opening of the high school day. The Minneapolis school district, for example, changed its start time from 7:20 to 8:40 a.m., giving its 12,000 high schoolers an extra hour and twenty minutes each morning.

Researches show that students in schools of these districts benefit a lot from the change. Students reported less depression when there was a later starting time. And teachers reported that students were more alert and ready for learning. Parents reported that their children were easier to live with because their emotions were more regulated.

Teachers especially wanted a change because they were concerned about student attendance and student readiness to learn that first period of the day. The change resulted in better attendance and less student sleeping in class that first hour.
