什么叫“低排放区”？ | 六分钟英语( 二 ) _空气污染

Let's hear from an expert on this - Alastair Lewis,让我们听听这方面的专家阿拉斯泰尔·刘易斯是怎么说的，
who is a Professor of Atmospheric Chemistry at the University of York.他是约克大学大气化学方面的教授。
He spoke to BBC Radio 4s Inside Science programme and explained why we should be trying to reduce these pollutants,他在BBC广播4频道的Inside Science节目中解释了为什么我们应该努力减少这些污染物，

a word for the substances that cause pollution…那个词是指造成污染的物质……
Most of the evidence we have now on air pollution is that we continue to see health benefits by reducing pollution,关于空气污染，我们现在掌握的大部分证据是，我们仍会看到减少污染对健康的好处，
even when you're below the target value.即使你低于目标值。
So just because the city meets a particular value, there is still an incentive to continue to improve air quality,所以虽然城市达到了特定值，我们仍有动力继续改善空气质量，
because the health benefits continue to build up as you do that.因为在你这样做的时候健康益处会继续增强。
So targets are very good at focusing the mind,所以目标是非常有利于集中精神排放英语，
but they shouldn't be the only thing that we're considering.但它们不应该是我们考虑的唯一内容。
Alastair Lewis mentions targets.阿拉斯泰尔·刘易斯提到了“目标” 。
These are official levels of something that need to be achieved.这些是需要达到的官方水平。
They give us something to aim for, in this case reducing air pollution.它们给了我们一些目标，在这种情况下就是减少空气污染。
He uses the phrase focusing the mind.他用了“集中精神”这个短语。
That means to concentrate on one idea or thought.那指的是专注于一个观点或想法。
But, while setting a target to cut air pollution is good, it has health benefits,虽然设定减少空气污染的目标是好的，它对健康有益，
we shouldn't just focus on meeting the target.但是我们不应该只专注于实现那个目标。
Even if the target is met we shouldn't stop trying to improve.即使实现了目标，我们也不应该停止努力提升。

The incentive should be that we are improving people's health.动力应该是我们要改善人们的健康。
And an incentive is something that encourages someone to do something.动力是鼓励某人做某事的东西。
So I think it's accepted that creating low emission zones is an incentive,所以我觉得人们认可创建低排放区是一种动力，
because it encourages people to either not drive into cities or to, at least, drive low-polluting vehicles.因为它鼓励要么不开车进入城市，要么至少开低污染的车辆。
And, of course, changing to electric-powered cars is one way to do this.当然，改用电动汽车是实现这一目标的一种方法。
There's more of an incentive to do this now,现在有更多的动力这样做，
at least in the UK,至少在英国是这样，
because the government has said new diesel and petrol cars and vans will be banned from 2040.因为政府已经表示，从2040年起，新的柴、汽油轿车和柴、汽油货车将被禁止。
But pollution from vehicles is just part of the problem, as Alastair Lewis points out…但正如阿拉斯泰尔·刘易斯所指出的，来自车辆的污染只是问题的一部分。
