　　Too much homework has become a common complaint in high schools and elementary schools. Students have to spend most of their time doing homework, even on weekends. As a result, they have no time for their hobbies, or for their parents or friends. All they do is what they have to do, not what they like to do.

　　The underlying cause for this phenomenon lies in the present exam-oriented education system. National College Entrance Examination has become the sole focus of teachers, parents, and students themselves. High score becomes the ultimate goal, to the neglect of practical abilities, personality development, and all that.

　　It is urgent that we deepen our educational reform. We must allow for students' overall development, not just evaluate their test scores.
