pollute中等

Madrid was hailed as a public health guiding light last November when it rolled out ambitious restrictions on the most polluting cars.

去年11月，马德里对污染最严重的汽车推出了雄心勃勃的限制措施，被誉为公共卫生领域的指路明灯。

Restrictions that keep highly polluting cars out of certain areas — city centres, “school streets”, even individual roads — are a response to the absence of a larger effort to properly enforce existing regulations and require auto companies to bring their vehicles into compliance.

禁止高污染汽车进入某些区域——市中心、“学校街道”，甚至个别道路——的限制措施，是对缺乏更大力度的努力的一种回应，这种努力指的是切实执行现有法规并要求汽车公司使其车辆达标。
