根据短文内容完成下列各题。

     "Mother tells me that the most important is to study, and she almost never gives me any housework to do,

though I really want some," said Wang, a middle school student in Guangzhou, capital of South China's

Guangdong Province.

     A report says that most of Guangzhou teenagers (青少年) want to do more housework, but their parents

usually do not think so. According to (根据) the report, 37% of the teenagers do housework less than half an

hour every day; 39.4% of them from half an hour to one hour; 11.5% one to two hours; 5.6% over two hours;

and 6.2% just have"no" housework to do.

     "Most of my time after school should be spent on my homework, and I don't have time to play. Even on

weekends, my parents ask me to stay at home to study. I can't go to see a film, watch TV or play with other

children. My parents never say to me about anything to do with the housework. Sometimes I feel I have the

duty to do something to help my parents, but they just get everything done for me," said Yang Ming, a sixteen-

year-old student.

     Experts say this won't change much unless the College Entrance Examination, which adds much pressure (压力) on high school students, is changed.
