超短篇英语演讲稿1We Need A Blue Sky
In recent years heavy smog often appear in many cities of China, which has brought bad impact on our daily life. Since the value of PM2.5 inthe air is in the high level, many people wear masks to protect themselves when going out. Once in an area, due to the emissions of smoke from coal burning and car exhaust, the atmosphere was so heavily polluted that people couldn’t see their own fingers just in front of them and some schools and airports had to close down.
When a strong sand storm is blowing, the whole sky will turn darker and darker. It looked as if we had been spending the night when the sun is high upin the sky. It is high time we tackled with the pollution problems.
