1. 口语交际：观察表格,和你的小伙伴讨论下面这些城市在2022年7月某一天的空气质量,分析哪些因素影响空气质量,并提出你的建议。(注：AQI指数越高表明空气质量越差)
| City | Shenzhen | Beijing | Tianjin | Shanghai | Haikou |
| AQI(空气质量指数) | 21 | 52 | 74 | 27 | 13 |

The air in... is... It’s a... city. There are... in the city. The people there... We should... We shouldn’t...

答案： The air in Haikou is very clean. It’s a fresh city. There are many trees and few factories in the city. The people there can enjoy fresh air. The air in Tianjin is poor. It’s a polluted city. There are many cars and factories in the city. The people there may feel uncomfortable. Factors: More cars and factories make air poor; more trees make air clean. We should plant more trees and drive cars less. We shouldn’t let factories give out too much smoke.
