Part A听写题: Note-taking and Gap-filling
讲评:
今年的Note-taking and Gap-filling核心话题为解释一些与环境资源治理有关的术语,继续了历年常考的环境类讲座,总体而言,难度不大,很多空格在试卷上给出的summary文本中都可以直接找到答案,而略有挑战性之处在于有些空格需要考生对原文大意有较好的认知,考查考生概括和总结大意的能力。
参考文稿及答案
So, I want to discuss a few other terms here, actually some, um… some ideas about how we manage our resources. Let's talk about what that means. If we take resource like water, now maybe we should get a little bit more specific here, back from a more general case and talk about underground 1. 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 gonna to 2. deplete the mount 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 3. 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. 4.(第四空填写表示否定的词即可) But what it does is it 5. ignores how much water naturally comes out of the system, and natural system of certain matter of recharge comes in and certain matter of water naturally flows out through springs, streams and lakes, and over long term 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 anymore? Right. We take water out but water also naturally flows out. And the recharge rate doesn't change. So the result is we've 6. 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't fix service water. How? Well underground systems there are natural discharge points, places where the water flows out from the7. underground systems, out of lakes and streams. Well, a8. drop of water level can mean those discharge points will eventually 9. dry up, and that means water's not getting to 10. Lakes and streams that depend on it. So we end up reducing the 11. surface water supply, too. You know, in the state of Arizona, we're 12. Managing some major water supplies with the principle of safe yield and under this method they will 13. eventually dry up the natural 14. discharge points of those aquifer systems. Now, why is this 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 maybe 15.concerned with "dose Arizona have water supplies which is sustainable-key word here. What that means? The general 17.definition of sustainable is whether it be enough to meet the 18. needs of the present without compromising the ability of 19. future to have the availability to have the same resources. Now, I hope you see these two ideas are 20. incompatible---sustainability and safe yield. Because what sustainability means is that it's sustainable for all systems depend on the water, for the people who use it, and for supplying water to the dependent 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 has stored under ground gradually gets reduced, and that going to lead to another problem: these discharge points with water flow out to the lakes and streams, they're going to dry up. Ok.
