City composition in my heart 1: city in my heart

Time flies in the city in my heart, and it has been 20XX years in a blink of an eye. People's living conditions are getting better and better, and technology is developed, but the environment is getting worse and worse.

I read a news in the newspaper that a polar bear was looking for a new ice layer because the ice layer melted, but because of physical exhaustion, it was too late to find the ice layer and drowned in the sea The same is true in our city. Because there are too many cars, roads are widening and green belts are being cut. Although cars are convenient to drive, there is less green in the world. Our Jinhua is not bad, but the environment in Beijing and Shanghai is really bad! The whole city is so crowded with cars that people can't walk. I think it is necessary to limit the number of cars purchased each month and shorten the car scrapping period by 1-2 years, so as to control the growth of the number of cars. It is also necessary to appropriately broaden the green belt, improve the urban environment and purify the urban air. Now go to the suburbs of the city and take a road with fewer cars into the Woods. Let's talk about how to protect the green belt. Now sanitation workers in cities always clean up fallen leaves on the soil, but fallen leaves can be used as fertilizer for trees. Without fallen leaves, the growth of plants will be much slower. Also, don't cut too many branches, just cut them irregularly.

I believe that as long as everyone cares about the environment, the environment will definitely become better!

My City Composition 2: My City

The city in my mind has five floors.

There is a subway on the first floor. The subway can go anywhere. The subway is very fast, with an hourly speed of 1000 km. If you have the ability, you can do some tourist attractions and let the subway take us there.

The second layer is the ice and snow layer. It's too hot in summer, so it's very cool to play on the second floor. And skiing.

The third floor is the human world, where there are schools, gardens, playgrounds, shops and restaurants. To be particularly good, the school had better not take the exam, but take the exam once a semester at most, with little homework. It is best to go to school later every day, at 9 o'clock, after school at 3 o'clock in the afternoon, and eat at school at noon. You can skateboard and ride a bike at school. You can only ride a bike, not a car or a motorcycle on this floor. It's cooler here than three floors.

The fourth floor is similar to the third floor, with schools, playgrounds, shops and restaurants, except that it is warmer in winter, which can be on the third floor in summer and warm in winter. You can drive here.

There are many cars from factories and steel mills on the fifth floor, and there are glass on the next four floors to prevent harmful gases from entering people's paradise.
