One possible version
This special pen was invented by my English teacher, Liu Jie. It has three colors and is used for taking notes quickly in class. It was invented in 2021. It is made of plastic and steel. It can remember what the teacher said. It can also help write down the main points.When you don't know how to use some words, phrases or sentenses, you can review them by using it. Since I used it, I have made great progress in learning English. I think it’s a useful invention. It will be more and more popular. If you want to improve your English quickly, you must spend ten dollars on one.
