昂秀英语口语对话想聊就聊第5章：5.2 环境污染

M: Well, no one could survive without water, but you see pollution has been making more and more water unable for drinking.
M：如果没有水谁也活不了，但是你看，污染正使越来越多的水没办法供人饮用。

W: Yeah. Water pollution has for a long time been a major concern among the environmental issues.
W：是啊，长期以来水污染一直都是环境问题中备受关注的。

M: But what are the sources of water pollution?

M：但是都有哪些污染源呢？

W: They could generally be divided into two categories: direct and indirect contaminant sources.

W：可以分为两大类，即直接污染和间接污染。

M: Well, direct ones are the pollution directly from factories, refineries waste treatment plants etc., aren’t they?
M：嗯，直接污染是指工厂、冶炼厂、废水处理厂等地方直接排出来的废物，是吧？

W: Yeah. They are emitted directly into urban water supplies.
W：对，它们不经处理就直接排到城市居民的饮用水源里了。

M: But what about the indirect ones?

M：那间接污染是什么呢？

W: Indirect sources include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rainwater.

W：间接污染是从泥土、地下水系统以及通过雨水从大气中进入水源的有害物。

M: I see. For the sake of us all, we should be an active participator in the prevention of it.

M：我知道了，为了我们自身的利益，我们大家都应该积极参与到防止污染的活动中去。

W: Sure. It's an issue asking for everyone's participation.

W：就是，这是个人人都应该参与的事情。
