三、考题对应考点
6. Some nutrients are quite scarce; there just isn’t much of them in the environment. But fortunately they get recycled.开头原则的直入主题式，开始教授就说现在营养元素在自然界中的量不多，主要靠循环来得到充分利用，借此引出了nutrient cycle 这个概念，所以选择D.
7.第一种是制作和使用肥料，humans can play a role in a first part of the Phosphorus cycle -- the breaking down of rocks and the spreading Phosphorus into the soil by speeding up the rate at which this natural process occurs，也就是D;第二种是钓鱼，The fishing industry helps bring Phosphorus back to land,也会是A选项。
8.After millions of years, powerful geological forces, like underwater volcanoes lift up the ocean sediments to form new land. When an underwater volcano pushes submerged rock to the surface, a new island is created. Then over many more years the Phosphorus-rich rocks of the new land begin to erode and the cycle continues.在海底的phosphorus 通过海底火山的爆发来到海洋表面，这是完成phosphorus cycle 的一个步骤。所以答案应该选C.
9.This could cause a rapid growth of water plants in the river, which can lead to the water waste getting clogged with organisms, which can change the flow of the water. Several current studies are looking at these effects and I really do hope we can find the way to deal with this issue before these ecosystems are adversely affected.如果大量的phosphorus 进入到河流中，将引起水流的变化，她希望有关研究可以尽快找到解决办法。所以选择B，她是concerned的。
10. 学生说And there is a lot of nitrogen in the atmosphere, so I was wondering, is there a lot of Phosphorus in the atmosphere too?教授回答 However, there’s just not a substantial amount of it there, like there is with nitrogen, it’s a very minimal quantity.结尾原则，结尾出现的内容要注意，however后面的内容也是考点，所以选择B，大气中nitrogen 比phosphorus多。
11.重听内容：Yes, that’s such a difficult point isn’t it?Nancy 做的这个推论非常直接和简单，所以这里教授这句话的意思是“这个问题就只有这样的难度”，答案应该选 C，教授提出的问题非常简单，答案很明显，不要被句子所迷惑，这种题型要注意上下文之间的联系。
听力文本结构框架：
这篇讲座主要讲的是磷循环，磷在是非常重要的养分并且也不是很充足。磷循环包含陆地循环和水循环两个阶段。
