The teacher won't without criticism a student,also won't reason to reward a student.Just like the world for us the same,so is fair.
Of course,this was the moral,very qualified teachers speaking.
So I think there are criticisms makes progress,so just let teachers and parents happy.
Can play a great delight to fall,life.
翻译：老师不会无故的批评一个学生,也不会无故的去奖励一个学生.就像世界一样,对我们所以的人都是公平的.当然,这也是对道德高尚,非常有资质的老师而言.有批评才有进步,这样才让老师和家长高兴.能起能落,人生一大快事.
