  英语高级口译听力部分备考,首先要掌握高级口译教程,高级听力教程里的题尽量多做,因为会选一部分原题作为考题。然后是真题,找10-13的题目来做熟悉题型。note-taking and gap filling挖掉的空很细节,数字、列举、主题,各种各样,所以就是靠听的时候做笔记。上外口译为大家整理了2013年9月高级口译真题听力填空题的文本解析,供大家备考练习使用。

  Note Taking and Gap Filling

  Good morning, ladies and gentlemen. Last week, we talked about some important terms in environmental science. Shall you still remember them, right? So in today’s environmental science class, I want to discuss a few of the terms here, actually some ideas about how we manage our resources. Let’s talk about what that means.

  If we take resources like water, now maybe we should get a little bit more specific here, back from a more general case and talk about underground water in particular. So hydro geologists have tried to figure out how much water can we take out from underground sources. That has been an important question. Let me ask you guys, how much water, based on what you know so far, could you take out of , say, an aquifer… under the city? As much as what gets recharged?

  Ok. So we wouldn’t like to take out more than naturally comes into it. The implication is that, well, if you only take as much out as comes in, you’re not going to deplete the amount of water that stores in there. Right?

  Wrong. But that’s the principle. That’s the idea behind how we manage our water supplies. It’s called “safe yield”. Basically what this message says is that you can pump as much water out of the system as naturally recharges, as naturally flows back in.

  So this principle of safe yield is based on balancing what we take out with what gets recharged. But what it does is it ignores how much water naturally comes out of the system, and a natural system of certain matter of recharge coming in and certain matter of water naturally flowing out through springs, streams and lakes, and over long terms the amount that’s stored in the aquifer doesn’t really change much. It’s balanced.

  Now humans come in and start taking water out of the system. How have we changed the equation? It’s not balanced any more. Right. We take water out but water also naturally flows out. And the recharge rate doesn’t change. So the result is we’ve reduced the amount of water that stores in the underground system. If you keep doing that long enough, if you pump as much water out as naturally comes in, gradually the underground water level will drop.

  And when that happens, they can affect surface water. How? Well, in underground systems there are natural discharge points, places where the water flows out from the underground systems and into lakes and streams. Well, a drop of water level can mean those discharge points will eventually dry up, and that means water’s not getting to lakes and streams that depend on it. So we end up reducing the surface water supply, too.

  You know, in the state of Arizona, we’re managing some major water supplies with the principle of safe yield and under this method they will eventually dry up the natural discharge points of those aquifer systems.

  Now, why is this an issue? Well, aren’t some of you going to want to live in the state for a while? Won’t your kids grow up here, and your kids’ kids? You may be concerned with “does Arizona have water supplies which is sustainable—a key word here. What that means? The general definition of sustainable is whether it is enough to meet the needs of the present without compromising the ability of the future to have the availability to have the same resources.

  Now, I hope you see these two ideas are incompatible---sustainability and safe yield. Because what sustainability means is that it’s sustainable for all systems that depend on the water, for the people who use it, and for supplying water to the dependent water bodies like some streams.

  So I’m going to repeat this. So, if we are using a safe yield method, we’re only balancing what we take out with what gets recharged, but don’t forget, water also flows out naturally. Then the amount that has stored under ground gradually gets reduced, and that is going to lead to another problem: these discharge points with water flowing out the lakes and streams, they’re going to dry up. Ok?

  【评析】话题 environmental science

  本段落改编自TOEFL Official Guide (第3版) Practice Test 1 Q11-16,重点讲了underground water 地下水的平衡问题。自然界的水循环模式是通过雨雪等形式的降水补给水的来源,水又通过泉、河、湖泊等形式变成地表径流流失或者地下径流存储在地下水体里。人的介入,即抽取过多地下水,会破坏原有的地下水平衡,导致水量减少。

  近3年的高口NTGF难度有所增大,文章难度变大,而且选材上有点捉襟见肘,开始借用托福的听力讲座了。这篇材料如果要把它和经典的高口NTGF选材联系在一起的话,可以属于环保话题里的对自然资源的过度利用,但是本文的具体细节依然太过学术,并非一篇十分到位的NTGF材料。同样的现象体现在1303的高口NTGF中,虽然话题是讲人为何要进行宇宙探索,但是中间出现较专业的托福天文词汇,如asteroid小行星等。相比这2套题,还是1303的这一篇出的更好一些。
