备战中考寒假系列答案【题目】Have you ever paid attention (注意)to the Air Quality Index (空气质量指标) or AQI reported in the newspaper? The AQI helps us understand what the air quality around us means to our health.

Orange | 101~150 | Unhealthy for sensitive(敏感的) groups | Active children and adults and people with lung (肺) disease (疾病) should spend less time outdoors. |
