托福听力排序题考点精析
关键字：排序题，实验，工具，提示词
托福听力排序题是指要求排出某一事物形成过程具体顺序的题目。

这类题目向来是学生们的难点，这是因为排序题要求学生所听信息全面而具体，也就是说学生的听力基础能力得非常好。

但若能提前预知一篇文章是否会出排序题，便能提前记录好相关信息，做题也就轻而易举了。

排序题通常源于实验的形成过程，工具的使用顺序和以时间为依据的历史事件的讲座中。

由常理可知，这些过程都不可避免的会用到一些表示顺序的提示语，常用提示语有what they did was…; first, second, third…; then, after that…
把握了以上的出题规律，我们便可以提前预测讲座是否会出现排序题。

例如TPO1-L2，这篇讲座中涉及了一个实验的操作过程，其中的具体描述如下：
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 lava from volcanoes. This magma then crystallizes. And when Zircon crystallizes, the Uranium inside it begins to change into Lead. So if you measure the amount of Lead in the Zircon grain, you can figure out when the grain was formed. 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 the Zircon matches the age of one of the mountain ranges, then it means the sandstone actually used to be part of that particular mountain range.
可以看到以上例子所描述的内容为一个实验过程，而且当中出现了操作过程的具体提示词，所以学生在未看到题目时便可提前预测这极有可能出排序题并记录好相关的内容。

其实，排序题并没有太多解题技巧可言，只有掌握其出题规律才是真正可取的突破口。
