     This year, Chongqing primary schools decide to start morning classes an hour later. This will help

students feel less tired. And most primary schools will begin the first classes at about9o'clock in the

morning.

     The students are happy about the change.

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

now on we students at Hope Primary 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 7:50 am because class doesn't start until 8:50 am.

     Wu Hong 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 No. 1 Primary School. "But now

they are active 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.
