Are you feeling sleepy in class?I remember that I used to get up at eight when I was young．And we didn't use to do homework．But now, everything has changed．
For 12-year-old Liu Xiangjian, the most difficult thing in life is getting up at 5：50 a. m．every school day．
“I don't want to get up so early, but I used to be afraid of being late,”the six-grade Beijing primary school student said,“I want more sleep．”
Liu has breakfast at 6∶15 a. m．a(chǎn)nd after a 30-minute bus ride, arrives at school at 7 a. m．Like most of his 28 classmates, Liu arrives at school a full hour before lessons start at 8 a. m．
In 2007, a survey of 2500 schoolchildren in six cities, including Beijing and Shanghai, it was found that about 77％ students were short of sleep．
In a recent survey made by the China Daily website, almost 70％ of the 1,130 respondents said that they agreed with cutting school hours, while 22％ disagreed and 10％ had no comment．
Although their children spend long hours at school, many parents arrange for them to take more studies．
Liu's mother, Wang Qunyu, who teaches at a high school in Beijing, thinks her son is still not doing enough to win a place at a good quality high school．
“Of course I want my son to have more sleep, more exercise and more fun,' she said,“but the common saying is that if you give your child a happy childhood in China, you give him a failed future．”
Something must be done to change people's traditional thought that a college diploma(畢業(yè)證)is a ticket to a good job．
