Twenty years later I will be in my hometown Essay, 450 words, be fast, all home

One day twenty years later, I returned to my hometown. The hometown after twenty years has been brand new. Standing in front of the airport, I couldn't believe my eyes. Twenty years later, my hometown is no longer a city with serious environmental pollution. At that time, the air level reached the level of the nineteen sixties; the water quality reached the standard of direct drinking; the ground has become green and tree-lined, and dust storms are out of the stage of history.

Twenty years later, not only has the environment improved a lot. People's mode of transportation, living environment, communication methods have changed a lot. At that time, people were no longer traveling by gasoline-burning cars, but by power-driven environmentally friendly cars or light gliders. The skyscrapers on the ground had been built underground, and the ground had been turned into a square. Communication is no longer by cell phone, but by low-radiation micro-headsets.

Then I returned to my alma mater, Anshan Road Elementary School. The environment there has been renewed, with the teaching building built underground and the playground occupying the entire campus. The classrooms have also changed. Students rely on computers to interact with teachers, the curriculum has become diversified, and the management of students has become intelligent robots. After I left the school, I went to an environmentally friendly chemical factory, which produces all kinds of plastic goods. The reason why it is called an environmentally friendly factory is that there is now a machine that can purify waste residue, sewage, and harmful gases. Sewage, residue can be used as fertilizer after purification."

Twilight fell, I walked into a palace like 'small city', the house is all made of glass, the inside can be seen outside, the outside can not see the inside. In the morning, this place is like the ice sculpture city of Harbin, and in the evening, when the lights are turned on, the countless reflections of light are like the "city of night" New York, and even comparable to New York. This is China's New York, people call this place 'Oriental City of Night'! After dinner, I had something urgent to do, so I was reluctant to leave.
