阅读短文，完成下列任务。
Do you enjoy travelling? I like travelling. But I noticed that hazy weather often appeared in many cities when I went on vacation. The hazy weather in China is becoming more and more serious. It not only does harm to people's health, but also affects public traffic safety.
Hazy weather affects our life a lot. We must pay attention to hazy days.
- Avoid going out. If you have to, please wear a face mask.
- Wash your face and clean your nose as soon as you get back home.
- Try not to exercise outside on hazy days.
- You'd better close the windows on hazy days.
- Drink more water, and eat more fruit and vegetables.
China can't afford to wait another five or ten years to solve the problem. In my opinion, there are many ways for us to protect our environment. First, don't throw rubbish anywhere. Second, go to school or go to work by bike or by bus instead of driving private cars. Third, join a programme to protect the environment. It's our duty to keep our city clean, tidy and beautiful. And everyone should play a part in saving the Earth.
