An invention for students
Good morning, everyone! I’d like to introduce my new invention to you.
It’s a special pen. It’s made of steel. It is as heavy as a normal pen, but it’s a little longer. There are three buttons on the pen. First, it can be used as a pencil, a pen or an eraser. When you press the red button, it is used as a pencil. When you press the blue one, it is used as a pen. If you want to use an eraser, you can press the white button. Second, it will let you know if you’re sitting correctly by making a sound. It won’t stop making a sound until you sit correctly. I think it’s very useful and convenient.
Thank you for your listening!
