Excerpted from a short sentence about playground and campus scenery.

1. Step into the school gate and walk through the long corridor, and you will see the playground of our school. If our school is like a ring necklace, then the playground is like a pearl embedded in the middle of this necklace. The playground is not only the center of the school, but also the happiness of our students entering the campus. The first thing you see is the brightly colored playground. The playground is red and green, red is a long runway, and green is a grassy football field. Red and green set each other off like a flower with green leaves and red petals. Walking into the playground and stepping on the soft grass, you will have an unspeakable relaxation. The white lines outlined on the red runway are graceful like dancing skirts on the playground. This is just the first beautiful scenery on the campus playground.

I came to our future school-Zhongguancun No.3 Primary School. I stood outside the school gate, which opened automatically. When I first entered the campus, I first saw the school playground. The school playground is high-tech. If it rains, it will fall into the basement, and then the floor that was originally in the basement will automatically rise. There are several temperature and humidity regulators in the underground playground. These control devices can control the temperature and humidity of the underground playground, so that students can breathe fresh air in the underground playground and we can go to physical education class in the underground playground.

There is a robot in front of the school to protect people and property in the school. It greets us and invites us to enter the school. We entered the teaching building by escalator. The ceiling of each classroom is sky blue and the floor is grass green, which makes students feel as comfortable as taking classes in nature. When we walked out of the teaching building, we found that there was no playground in the school. The robot pointed to the underground passage next to the teaching building. In order to save space, the playground is built underground. There is a light button on the playground. With it, even underground, it will be like daytime. There are basketball courts, parallel bars and other venues on the playground. Even if it is windy and rainy, you can play happily on the playground.
