Future ocean composition

The Future Sea In the 22nd century, my parents and I moved from a crowded city to this beautiful "Pearl of the Sea" city. The city is a sphere surrounded by a special transparent film, hence the name "Pearl of the Sea". Although this film looks transparent and soft, it is actually very tough. The violent erosion of the sea and the biting of the sharp teeth of the great white shark made it unbearable. City dwellers can reach out and play with crabs, soldiers and shrimps like a thin mist. People can also see a colorful underwater world through the film, with all kinds of grotesque fish, lined seahorses, octopus waving long limbs, and aquatic plants writhing with the current.

After breakfast, I said goodbye to my parents, and I set foot on the crystal channel leading to school. Speaking of this crystal channel, some universities still ask!

This is made of crystal glass tube, which is divided into three layers: electric racing track and walking track. Among them, the most widely used is the first-floor moving sidewalk, which is divided into four rows at the same time. The speed of the first, second, third and fourth rows is 50 km/h respectively. 30 km/h; 20 km/h; 10 km/h. It carries thousands of passengers like an assembly line. The second floor is an electric driveway, which is suitable for fans. On the third floor is a promenade, where you can often see some old people walking slowly with their pets; This three-layer crystal channel runs through the city, which is convenient and high-speed.

Five minutes later, I arrived in the city center, where there was a huge fountain like a five-story pagoda. It is not only beautiful, but more importantly, it is also an oxygen generator in the city. Next to the fountain is a station, or rather a "ball station". People only need to enter a sphere, and the sphere is controlled by a computer, so they can ascend to another underwater city or land. Every weekend, my mother takes me to grandma's home on this sphere.

Soon, the school arrived. This is a book-like building, symbolizing that we are swimming in the sea of books. Colorful flowers and plants surround the school, which is planted with fertilizer jelly. They are delicious! Also brought the pencil butterfly that Dr. A just introduced!

This is our "pearl under the sea". The reason why there is such an underwater city is that the population on the land is increasing day by day, crowded, and the environment is polluted. The area of the ocean far exceeds that of the land, and human beings have to rely on science and technology to return to nature! I thought: Since human science and technology can allow us to settle on the seabed, what will the Sky City and Mars Garden look like in a few years? We still need to explore and study, and I believe there will be another style.
