Dear Senior Three students,
Towards graduation,many senior three students are busy packing up the used textbooks,reference books and test papers to sell them as waste paper.We think it a waste of money and resources.If well arranged,they can be reused.So our proposal is as follows.
Start with sorting out all your materials and make a list.You will find some quite special and meaningful,some textbooks,for example,which record your school life.You can keep them as part of your memories.As for some useful reference books and test papers,we consider it a good idea to give them away to the students of Senior One or Two.They will be grateful to you for your generosity and kindness.
Don't hesitate to take action.We are looking forward to your participation!
