Life on earth depends on waterand there is no substitute for it The current assumption is that our basic needs for water-whether for drinking agriculture industry or the raising of fish--will always have to be met Given that premise there are two basic routes we can go more equitable access to water or more drastic engineering solutionsLooking at the engineering solution first a lot of my research concentrates on what happens to wetlands when you build dams in river basins particularly in Africa The ecology of such areas is almost entirely driven by the seasonal change of the river--the pulse of the water And the fact is that if you build a dam you generally wreck the downstream ecology In the past such problems have been hidden by a lack of information But in the next century governments will have no excuse for their blissful ignoranceThe engineers ability to control water flows has created new kinds of unpredictability too 'Dams in Africa have meant fewer fish less grazing and less floodplain agriculture--none of which were anticipated And their average economic life is assumed to be thirty years Dams don't exist for ever but what will replace them is not clearThe key issue in any discussion of water is money To talk about a water crisis hides intractable problems such as povertyConsider the problems of water supply in Mexico City or Delhi If you' re rich you drink mineral water and may even have a swimming-pool--yet millions in such cities can't get safe drinking water People talk about the coming water crisis I believe we have one now It is a water crisis for the poor 地球上的生命依赖于水，而且水是无法替代的。 目前人们的假设是，不管是饮用水还是农业、工业、渔业用水，我们对水的基本需要能够得到满足。在这一前提下，我们有两条基本道路可走：更合理地利用水资源或建立更多大型的水利工程。先来看看水利工程问题。我的大量研究的焦点在于如果你在河谷(尤其是非洲河谷)建立大坝，这会对湿地产生什么影响。该地区的生态几乎完全受控于河流的季节性变化——河水的涨落。事实上，如果你在上游建了水坝，通常会破坏下游的生态环境。过去，这类问题由于信息匮乏而鲜为人知。但在下个世纪，政府就不能为自己的盲目乐观找借口了。 工程师控制水流的能力产生了新的不可预知的结果。在非洲建水坝意味着渔业减产，草场减产，洪水泛滥区农业产量下降，所有这些都是事先未预料到的。而我们假定水坝的平均经济效益的寿命为30年，但水坝不会永远存在，我们还不知什么可以替代它。有关水的讨论的关键在于钱。谈论水危机掩饰了诸如贫穷这样棘手的问题。考虑一下墨西哥城或德里的水供应问题。如果你富有，你可以喝矿泉水，甚至于可以拥有一个游泳池——而这些城市数以百万计的居民却喝不上安全的饮用水。人们讨论着即将到来的水危机。我想我们现在已经有水危机了，这是一场穷人的水危机。

注重首句，抓住主旨。

听力考试中最忌讳的就是词词计较，力求听懂所有词。无论听什么，注意力都不要在每一个字或词上面，而是对文段或对话内容的整体的理解上。开始前迅速扫视书面文字中的题干及选项，通过扫视联系上下文，有根据地预测文段发生的时间、场所、人物，并预测出谈话的大致内容。如果为了解答主旨问题就要着眼于首句，如果为了回答细节问题就要注意中间部分。听录音时，既要不断输入、理解、存贮信息，又要不打断听的过程。既要集中精力听，又要用心记。紧扣话题，把握说话者的思路，捕捉信号词，连贯记忆主要信息。听完试题后，要前后联系，利用后面听到的信息补充前面漏听的或有疑问的信息，并对听前、听中的预测和判断加以推理、分析、修正，以使理解的准确性更高。
