【听力原文】

Look at our topographical map andyou'll see that the middle third of the North American continent --- from the Rocky Mountains almost to the Mississippi River --- is pretty flat. This is the Great Plains. This kind of area is some times called a prairie, sometimes asteppe. That's [ess-tee-ee-pee-pee-ee]. The defining features are level terrain, dry climate, and an absence of trees.The Great Plains are actually the former bed of shallow inland sea. Over millions of years, sediment left by glaciers, water, and wind smoothed out the dry sea bed.As I said, the Great Plaints are bordered on the west by the Rocky Mountains. And it's really the Rockies that are responsible for the formation of the grasslands. The mountains are so high that they block the heavy moist air traveling eastward form the Pacific Ocean. Lighter, drier air passes over the mountains. Until people intervened with irrigation and farms, only grass could grow on the dry, windyplain. In fact, we can divide the Great Plains into three zones. In the west,where it's driest and windiest, the grass is very short. In the eastern zone,there's more rain and grass grows as high as 360 centimeters. In the middle third, there's a mix of grass species that grow to an intermediate height.

训练营进入第六天，今天要分析任务的主题是美国大草原，相信有许多同学以后去到美国都很可能有机会去美国的大草原旅游。所以现在在练习听写的同时普及一下相关的知识还是很有必要的。

好啦，原文看完，现在我们逐条分析一下文章：
1、topographical在第一句话里边有这样的一个单词，这是个比较生僻的词，意思是“地形学的、地质的”，但是第一次听到往往反映不出这个词的意思，不过好的我们知道graphica的意思，以至于在猜词的时候不会猜的太离谱儿。和这个词意思相近的次还有：geographical “地理学的”geological “地质学的”。大家千万不要把这些从搞混了噢。
2、Rocky Mountains almostto the Mississippi River，这里面有两个有名的地理专有词----落基山和密西西比河，学过地理的同学应该都知道吧，在此不多赘述。
3、Prairie是大草原的意思，和加勒比海盗里的pirate在发音上有些相似，但是大家一定要区分准确啊，要不然就该闹笑话了。还有一个词Steppe 也是大草原的意思，刚刚听的时候还以为是steep, 可是根据语境明显是一个名词，怎么想怎么觉得steep 没有名词的意思，因为一般情况下steep 的名词意思应该和形容词意思有一定的联系，不过还好后面有解释，就是材料里给拼写了一下，才弄明白这个词终究不是steep.
4、The defining featuresare level terrain在听力材料的这句话中，可能大家都能听出其中的单词，但是在做翻译的过程中可能觉得比较困难，主要是因为我们对单词的掌握不是很全面，只了解他们的主要意思，defining features，是定义特征，或者说是典型特征。Level 有“水平的”意思，所以level terrain意为“平坦地区”。
5、Block也是很容易听错的一个词，因为和bloc 的发音是一样的。但是即使有些同学听出了block,可能也不能正确的在脑中浮现其正确意思，block,名词有“大楼，街区”的意思，动词有“阻碍，防碍”的意思，而这里明显是动词词义。

【参考译文】

看看我们的地形图，你会看到从落基山脉，几乎到了密西西比河---theNorth美洲大陆的中间三分之一---很平坦。这是大平原。这种面积是有时称为燎原，有时一个草原。这是ESS-T恤-EE-PEE-PEE-EE]。定义的特点是水平的地形，气候干燥，一个缺乏trees.The的大平原，实际上是前浅内海床。经过数百万年冰川，水，风，泥沙离开理顺我说，伟大的感叹西部接壤的RockyMountains干海bed.As。它真的是负责草原形成的落基山脉。山是如此之高，他们阻止重moistair向东行驶形成太平洋。更轻，干燥的空气越过山。直到干预灌溉和农场的人，只有grasscould生长在干燥，多风的平原。事实上，我们可以分为三个区域大Plainsinto。在西方，它最干旱和强风，短草各执一词。在东部地区，有更多的雨水和草生长作为高as360厘米。在中间的三分之一，有一个成长为一个中间高度的草种组合。

好了，今天的文章分析完了，第一周就要过去了，快整理一下学过的东西吧，把不熟的单词词组记下来，加油，坚持就是胜利！
祝大家每天进步一点点！
