A 400-word article entitled "Returning to My Alma Mater after Twenty Years"

In a blink of an eye, twenty years later, I finished studying abroad and returned to my hometown. What has become of my alma mater? Go back and have a look Ah! Here we are! The first thing you see is rows of tall and straight trees, and the big characters of Tianjin Experimental Primary School embedded in the wall shine under the sunshine. Entering the school gate, an "intelligent robot" blocked my way. "Hello, what are you doing here?" "Let me see, this is my alma mater." Scan, scan ... "Please come with me and welcome back to my alma mater". Entering a school is like entering a beautiful garden. The campus surrounded by green trees and flowers exudes a faint fragrance. Spring water gushes among flowers and plants, and the air is particularly fresh. The beautiful teaching building is surrounded by flowers and green trees. Entering the teaching building, I came to my former Class 2, Grade 5, and found that teachers no longer had to eat chalk foam in class. All the students use e-books, and the teacher's lesson plans have been stored in the computer. All students and teachers can listen to the class and take notes by touching the computer screen lightly, and these notes will also be input into the computer, which can be opened at any time and reviewed at any time. At this time, the teacher asks a thinking question. Students who raise their hands only need to tap the screen, and their names will be displayed on the teacher's computer screen immediately. After a few seconds, the students' answers will be transmitted to the teacher. If they are correct, his score column will automatically accumulate scores. Seeing this, I smiled knowingly, and the intelligent robot led me out of the classroom lightly. Hey, how was the playground? The intelligent robot seems to see my question. I saw him press a button, as if time and space had changed, and an activity playground, table tennis table, parallel bars and football field appeared on the other side of the teaching. He pressed another button, and an activity stage appeared on the upper floor of the activity playground. Piano, microphone and lighting are all available, which is amazing! Twenty years later, the experimental park is even more beautiful!
