     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 about 9 o'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 aay 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 a.m. Now he can get up at 7:50 a.m. because class doesn't start until 8:50 a.m.

     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 a.m. I had to drink coffee every night, or I would feel too sleepy to finish my homework,"

said Wu. "Now I can fin- ish 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.

阅读下列列材料

  材料一：今日和议既成，中外贸易有无交通，购买外洋器物尤属名正言顺，购成之后，访募覃思①之士，智巧之匠，始而演习，既而试造，不过一二年，火轮船必为中外官民通行之物，可以剿发、捻②，可以勤远略③。——曾国藩《复陈购买外洋船炮折》

  材料二：……江南制造总局研制的无烟火药达到世界先进水平。但是江南制造总局是官办的，经费由清政府调拨，产品由清政府分配给军队使用，因为不计成本，不考虑经济效益，所以缺乏发展动力。制造总局的大权掌握在封建官僚手中，……员工大多缺乏生产积极性，他们又不重视改进生产工艺，产品质量不高，如生产的炮弹箍不合格，战时要锉平后才能使用，北洋海军在战斗中深受其害。——《普通高中课程标准实验教科书·历史1（必修）》人教版

注：

①覃思：深思。
