Grandpa and grandson watch the same night scene and have different experiences in writing.

In the evening, just after dinner, grandpa took his grandson to the balcony to play. Suddenly, a ray of light appeared on the horizon. Grandson said, Grandpa, look at that meteor. Grandpa said that the sky is not as good as before! I have been to see stars before! Sun Tzu said: I think the weather is much better than before. You see the sky brightly lit, just like in a beautiful fairy tale world. How beautiful, how beautiful. The sky in front of the children is so blue and fresh. After getting up in the morning, it's really comfortable to stand in front of the window for a while and breathe some fresh air. Not now. The sky is polluted by harmful gases emitted by various factories. The harmful gases in the air will be harmful to us.
