In a blink of an eye, twenty years have passed. In 2038, I have become a famous scientist. I drove my self-invented superluminal airship back to my long-lost hometown-Wuhu.
Just got off the plane, a thick fruity smell came to my nose. I looked around, and the road was still "Chery", as well as "BMW" and "Son of the East". However, the small hole in the rear of the car no longer emits black dirty gas, but is fruity, which not only does not pollute the environment, but also purifies the air. When walking on the road, I suddenly found two rows of small holes neatly arranged on both sides of the road, and the holes were covered with a layer of silk screen. What is this for? It turns out that this is a "playing device". When it rains, these small holes are used to collect rainwater. When it rains in summer, it will automatically spray a water column with a height of 1cm, making the ground wet. This road is called "environmental protection road".
Unconsciously, I came to my alma mater and walked into the classroom. Hey! There is a computer and a pair of headphones on the desk, but the textbook bag is missing. What happened? The contents of the original textbook have been collected in the computer. You only need to click on the content of the textbook, and rich pictures and wonderful textbook content will appear on the screen. Students don't need exercise boOKs to do their homework, just do it on the computer, sort out the information and send it to the teacher, and it will be "ok"!
The floor of the classroom is so clean, because of high technology, a badge vacuum cleaner is installed in four corners of the classroom, which sucks silently every day and through underground pipes. ...
Maybe you will ask: If there is too much dust, will it be full? Don't worry, if they suck it to a certain extent, they will put the dust into a mold and make a clay airplane that boys like and a clay doll that girls like.
I hope it will be the same in 20 years. I am determined to study hard now. I believe my hometown will be great in 20 years!
