I want to invent a multifunctional pen to write l50 words.

I write slowly, the pen doesn't like water very much, and the pen itself won't go to its place, so I invented the multifunctional pen.

The multifunctional pen I invented is convenient and quick, and there is no problem at all. If you don't have enough time to write, the pen will read to you, which will make you less nervous. If you can't write after class or homework, pen will be your study material, but it won't help you in the exam. If you are still in class, you'd better show this pen where you want to go. If you are sick, the pen will find out the cause and use what medicine to cure you. Sometimes if you are worried about studying, the pen will tell you, "As long as you don't give up, it will have a good effect." If you go to physical education class, Pen will look for your running posture and analyze your speed according to your physical fitness.

This pen will dance then! Just like a child who can talk, dance and live, do you know that this pen will always accompany you? Because it has a big circle and three rings below it, you can wear it on your lap and wait for the task you give anytime and anywhere.

How's it going? The multifunctional pen I designed is very good! As long as you want it to do something, I hope to invent such a multifunctional pen.
