   • 2004: 武少民 (Wu Shaomin), 来信选登:素质教育比不上高考升学率？ (Letters to the Editor: Quality education cannot compare to the rate at which students pass high school entrance exams?)

     就是這樣的一道檻，讓眾多的學子“三更燈火五更雞”，讓眾多的學校加課補課取消節假日.

     It's just this kind of threshold that causes many students to study late into the night, only to get up and go to class the next morning. It also causes many schools to add extra classes, including make-up classes, and to cancel holidays and days off.
