① While history has shown that the economic（经济的）development（发展）is sometimes made at the cost of environmental pollution, Shenzhen is trying to tell a different story.
② Shenzhen has been developing quickly in recent years. At the same time, the city's air quality has kept improving. In 2022, the average concentration（平均浓度）of PM₂.₅ was 16 μg/m³, the lowest level（水平）since 2006. The city has set a goal（目标）to lower it to less than 15 μg/m³ in two or three years and reach a world - leading level by 2035.
③ One of the most useful ways to curb air pollution is to use the electric vehicles（电动车辆）, especially in public（公共的）transport, across the city. At the end of 2017, Shenzhen became the world's first city to make all its public buses, about 16 400 of them, run on electricity（电）. A year later, more than 21 000 taxis in the city were almost electric cars.
④ When the sky becomes clearer, the city has also improved a lot in dealing with（处理）its water pollution. All 159 black and smelly water bodies and 1 467 small ones have been fully cleaned. Five main rivers that run through the city have met national water standards（标准）.
⑤ Maozhou River, one of the most heavily polluted rivers in Shenzhen, started to meet the lowest national standard for qualified（合格的）surface water in November 2019. The standard is that the water can be used for agriculture（农业）or sightseeing. This was the best level the river had had since 1992.
⑥ As a result, Chinese white dolphins and jellyfish have been seen to go back to the Shenzhen Bay（湾）. And the number of many animals in and along the river has grown up year by year.
