答案
1.Five. 由第二段可知，乍得、刚果、孟加拉国、巴基斯坦和印度这五个国家的空气最污浊。
2.Byrnihat in northeastern India. 由第三段可知，印度东北部的工业城镇拜尔尼哈特污染最严重。
3.Because it has stricter rules on pollution./Because it has pushed cleaner energy./Because it has spent money improving public transport.（从三条中选择任何一条即可）由第八段可知，北京和首尔之所以空气质量改善很大，是因为它们通过对车辆、发电厂和工业污染实施了更严格的规定，还推广清洁能源，并投入资金改善公共交通。
4.Yes, there is. 由倒数第二句可知，专家表示，改善环境还有很多工作要做。也就意味着还有很长的路要走。
5.Most of the people in the world breathe dirty air. 本文主要讲的是根据最新报告，世界上大部分地区空气污染严重，由此推出，世界上大多数人呼吸着污浊的空气。（答案不唯一，言之有理即可）
