Many people ask me what my favorite invention is. I find it very hard to answer them，because there are so many things in my life that I can choose. However，I have chosen a pen. Don't you think it's surprising
I know that to most people a pen is very boring，but，to me，it stands for possibility(可能).There are so many things you can do with a pen. You can write a novel or a song，record information，or draw a picture.
A pen is like the beginning of something amazing to me. Every day，I write a new page with my pen，and I am slowly making a path(路)for my future. Maybe I will be a scientist and change the world with my discoveries. Maybe I'll become a musician and touch people's hearts with my music. Or perhaps I will be a writer and move people through words，or a teacher to help children grow into the kind of people that they want to be.
There are so many possibilities as to what I will do with my life，but I know that with the pen in my hand，I will write a good future for myself. Tell me what future you will write for yourself.
