Hi, boys and girls. I have a special invention.
This special pen was invented by Liu Jie. It has three colors and is used for taking notes quickly in class. It was invented in 2012. It is made of plastic and steel. It can remember what the teacher said. It is very useful if you have a lot to write down. The pen can store a list of common words that you will use. When you are writing, you just need to write the short forms with the pen, press a button on the pen the related words will appear. It can also help write down the main points. Besides, it can also turn our voice into actual words. I think it’s a useful invention.

My invention is a flying bike. The flying bike looks modern and beautiful with two wheels and a pair of wings. You can either ride the bike on the ground or fly it in the air. Besides, you can not only take pictures of the beautiful scenery of our city, but also communicate with others when using the flying bike.
The flying bike has its own advantages. Firstly, its high speed can help you reach your destination quickly. Secondly, the flying bike uses solar power as energy, which can reduce air pollution. Therefore, it is environmentally friendly to use the flying bike.
What’s more, I will improve the flying bike in order to make it more helpful. The flying bike will be made of a light material so that it can be carried conveniently. As a helpful invention, the flying bike will be of great benefit to people. I believe it will be popular in the future.
