托福听力精听练习的正确打开姿势

　　第二步练习

　　如果听力一句句听，也能懂，但是段落听就不懂，这样的话，听力时应逐渐扩大断句长度，或者说是按意群听，一句句听有时会割断句间关系和意群间关系。(跟读和复述的区别)

　　方法：

　　如TPO1-L2 Geology：听一段音频，回答以下问题。

　　According to the professor, what change has causeduranium-lead dating to gain popularity recently?

　　___________________________________________________________

　　答案：

　　关键词出现 improved efficiency/ accuracy; it doesn’t take long time to get the result; or otherwordings that express similar idea 即可。

　　另外，也可以画段落、文章结构图

　　如TPO1-L2 Geology：听一段音频，将测量砂石年龄的过程以图示过程画出。

　　Uranium-Lead Dating allowed them to go aboutit in an entirely different way. What they did was: they looked at the grains of Zircon in the sandstone. Zircon is a material that contains radioactive Uranium, which makes it very useful for dating purposes. Zircon starts off as molten magma, the hot lavafrom volcanoes. This magma then crystallizes. And when Zircon crystallizes, the Uranium inside it begins to change into Lead. So if you measurethe amount of Lead in the Zircon grain, you can figure out when the grain wasformed. After that, you can determine the age of Zircon from different mountain ranges. Once you do that,you can compare the age of the Zircon in the sandstone in your sample to the age of the Zircon in the mountains. If the age of theZircon matches the age of one of the mountain ranges, then it means the sandstone actually used to be part of that particular mountain range. Is everybody with me on that? Good. So, in this case, Uranium-LeadDating was used to establish that half of the sandstone in the samples was formed at the same time the granite in the Appalachian Mountains was formed. Sobecause of this, this new way of doing Uranium-Lead Dating, we’ve been able to determine that one of our major assumptions about the Grand Canyon was wrong.

　　最后，听懂段落情况下，可以对意群句子或者段落进行“复述”，复述尽量用原文原词，但需要用自己组织的语言讲出来，组织语言的过程就是将听力内容理解和内化的过程，会对听力材料的理解大有裨益。
