Dear editor,

      It can be seen easily from the above chart that American students spend

72 minutes on physical activities per day, and those in South Korea 42 minutes.

However, Chinese students have only 12 minutes for physical activities per day.

The reasons lie in the following. Almost all the time is spent on lessons

in Chinese schools and students are made by parents to concentrate on their

study even when they get back homes. As a result, there is little time left for

their physical activities.

     In my opinion, both the Education Departments and parents are responsible

to give the students more time for physical activities. Anyhow, knowledge can

be learned not only from books but also through activities.

                                                                                             Yours sincerely,

                                                                                                           Li Hua
