     This year, Sichuan schools decide to start morning classes an hour later. This will help students feel less

tired. And most junior high schools will begin the first class at about 8:30 am.

     The students are happy about the change.

     Liu Ming told us that his class were excited by the news on the first day of school. "Great! From now on

we students at Chengdu No. 4 Middle School don' t have to get up so early!" Liu said that he used to get up

at 6:40 am. Now he can get up at 7:40 am because class doesn't start until 8:40 am.

     Wu Hongli feels the same. She said the new timetable (时间表) was good for her health. "I used to get up

at 6:30 am. I had to drink coffee every night, or I would feel too sleepy to finish my homework," said Wu.

"Now I can finish it without coffee. Because I can sleep a little longer."

     Many teachers say the change will help students learn better. "Students used to doze (瞌睡) for the first

two classes in the morning, " said Huang Shan, an English teacher at Chengdu No. 12 Middle School. "But

now they are active in class and learn much better than before."

     But some parents are worried that more sleep will mean less learning. There used to be five classes in the

morning. Now there are only four.

     In fact, every coin has two sides. So does the change in the school timetable.
