高级听力 Unit 16 Part 3

本网页涵盖两部分内容：

1） 关于伦敦空气污染，关于污染源。首恶是Sulphur Dioxide & Nitrogen Oxide，其次是 Ozone 。最糟糕的是，污染物质飘到空中之后，形成酸雨之前，还可能“漂移” 好几英里。

2） Jingyi 压箱底分享两种学霸的学习方法。从3-4个小时看十几甚至几十个案例，到建立网站直接形成社群，发挥领导力。只要内心有一种，一定要把期末考试过掉/考好，内心重视，一定会有解决方法。

3） 有时候做事结果不尽如人意，这时候就得质问自己，这件事我真的很想做好、真的很想完成吗？如果是这样，为什么我不专心致志地完成呢？因为思想上不重视？还是能力上没达到？通常，先检查后者，查看有没有弥补能力的方法，再不断质问自己思想是否重视。

Environment and Health

I’m going to talk about acid rain, a subject which many people have heard of but very few understand fully. I’m going to talk about exactly what acid rain is and why it’s a problem and then I’m going to finish off by saying what we can do about it, what the solutions are now and what the solutions will be in the future, in the long run.

So first of all, acid rain is a term that’s really being used now for a kind of pollution which is hanging over our heads in a sense -- it’s the rain pollution above us. It’s pollution that’s coming down in rain, in mist, in snow, in hail, in many different ways and damaging our forests, our lakes and rivers, our buildings and even human health. If we are to control acid rain, we must know what is actually causing it, so now I’m going to talk about the chemicals involved.
