Passage 

Is it necessary for students to spend more time studying during their winter holiday? I think not.Students have been working hard for several months now, and soon they will have completes all of this term's course. However unhappily, they may not be able to relax their tight nerves as usual, because I have heard that many middle school headmasters are considering holding classes in winter holidays. After five months of study, our students have become very tired, so perhaps, continuation classes are beyond them. What they need in the winter holidays is rest. Any more courses will only make them tiresome instead of helping them to progress in their studies. What's more, continuation classes will mean students fail to recover their energy, and this will affect their work next term. I do hope leaders of Education Bureau(教育局)will forbid such classes in the holidays and allow our students to have a good rest.
