A composition that you have experienced personally should have a description of the scenery.

Another "landscape" in the landscape

There is a world-famous company, and its system has a self-contained picture: blue sky and white clouds, delicious grass, which makes people feel that the sky and the ground are almost connected and harmoniously handed over. This picture was bought by Microsoft from a photographer at a high price and used as a landscape map of many computer wallpapers.

Once, many people regarded it as a place.

When the photographer returned to the original place, when the camera was aimed at the former direction again, he took a completely different "landscape" from what he had taken before: dark, grass everywhere, blue sky with layers of gray halo, clear and thorough air with hazy haze, and distant world looming in the fog gauze. People felt very surprised at this scene. I can't believe that this place will be the beautiful scenery I saw before. The blue sky has turned into a gray curtain, the grass has become a barren grass, it is no longer full of vitality, it is no longer poetic, and there is no longer a faint fragrance that once wandered around through photos ...

All this is caused by environmental pollution, and the foggy weather in Beijing these days is also caused by environmental pollution. It makes people wonder whether the foggy city is Beijing or London. It seems that London's status as a foggy city has been "shaky".

Last Saturday, PM2.5 in Beijing was heavily polluted, with the index reaching more than 8. The air should bring people freshness, vitality and life, but environmental pollution has made the air a "double-edged sword", which can easily take away life while keeping people alive. In the past, air pollution happened in Britain. However, at the London Olympic Games, there was no smog weather in the foggy city of London. Instead, it was good air quality. A reporter suffered from respiratory diseases, and as a result, he stayed in Britain for a few days and recovered.

During the Beijing Olympic Games, the government ordered some factories to close down or shut down several production lines. At that time, the air quality in Beijing was particularly good. However, after the Olympic Games, the factories reopened and the air quality dropped again. Go straight to the bottom of the valley. Some people sigh: "I hope China will be so fresh even if it doesn't open the Olympic Games."

A landscape often has another "landscape", which may be the past or the future. You don't know what it was like in the past, and you don't know what it will be like in the future.
