参考范文：My magic pen
I have been thinking about inventing a magic pen for many years. ： Every time when I see my classmates doing their home work with frustration and tiredness, how I want to give their some help and bring some relaxation to them; every time when I notice my teacher writing on the blackboard with great efforts and wiping his handwriting off the blackboard with a dusty hand, how eager I am to offer him some help and make him enjoy the happiness of teaching without dust.
After many errors and trials, today, I at last make it. I add some new functions to my usual pen.
Pressing the blue button, the users can enjoy some relaxation after a tiring and boring writing by listening to some beautiful songs, soft music, funny stories and radio programs for one or two minutes through a special earphone. Switching on the “T” button, which is intended for teachers, users can write smoothly on the blackboard at the same place time and time again, as the handwriting will be cleared up automatically when users write at the same place for a second time. I feel happy with my magic pen .
