The pollution on the earth is getting more and more serious now, and even our school can't escape its clutches. Sometimes, when the wind blows, it will raise a lot of dust, mixed with some sand, and want to fly into the eyes of students; What's more, there is an unpleasant smell in the air. It's okay in the classroom. If you walk out of the classroom, you can see that the chimneys of several factories are spewing white smoke into the blue sky. Every time we go to school, we are more miserable.
Then, an idea flashed through my mind, if only every student had an environmentally friendly schoolbag! How to design this environmentally friendly schoolbag?
Use green, because it is the color of life and health. It has to have the function of purifying the air, right? Then install a small vacuum cleaner on the left side of the schoolbag, which can not only absorb carbon dioxide, but also suck dust of all sizes, and then send the fresh and natural air out through the "filter"-the extremely thin tube at the edge of the schoolbag to the discharger on the right side. Do you need alarm and automatic control functions? Then install a microcomputer above the schoolbag, which can quickly and accurately measure the surrounding temperature, humidity, ultraviolet index and dust percentage. This microcomputer can also automatically adjust the speed of "vacuuming", "filtering" and "discharging" according to the environmental protection degree of the surrounding environment.
So where does this energy come from? Solar energy is the most environmentally friendly. Of course, this environmental protection schoolbag will not be without the function of putting books.
With the preliminary plan, next, I hope that Qi Xin will work together to develop it as soon as possible, so that everyone can have it as soon as possible, which is healthy and environmentally friendly!

The future schoolbag composition 300 words 9 Every day when we go to school, we have to carry a heavy schoolbag on our backs, feeling that our shoulders will be pressed from "flat shoulders" to "sliding shoulders". So I invented an e-book bag called "Xinyi Brand", which made it much more convenient for us to carry our schoolbags.
First of all, this schoolbag is as small as a wallet. There are two buttons with different functions on the schoolbag, which can be carried anywhere at any time. It can also be as big as the current schoolbag, but it is also very light to carry. E-book bags can hold many articles and books, while large books and small books can hold many books, and the weight is still very light.
When you come home from school every day, press the red button, and your homework will be displayed on the notebook-sized screen on your schoolbag. If necessary, you can also check your homework. If there is a wrong question, it will automatically circle it for you and send out a "Didi" sound to remind you.
