下面就让小编来为大家介绍一下这篇托福听力TPO2学习笔记的内容吧，这是小编的一些见解，以便帮助大家更加充分的理解TPO真题，希望能够给正在准备托福听力的考友们带来帮助。
一、难词注解
1.Textile
2.fibersn. 纤维(fiber的复数)
3.hempn. 大麻;麻类植物;大麻烟卷
4.resistantadj. 抵抗的，反抗的
二、长难句分析
1.Well, what you do is you extract these long fibers from the Manila hemp plant, and then you take several of these fibers, and you group them into a bundle, because by grouping the fibers you greatly increase their breaking strength—that bundle of fibers is much stronger than any of the individual fibers that compose it.
难句类型：
What引导的主语从句，because引导的因果关系，后跟伴随状语;that引导的定语从句;than比较级
难句拆分：
what you do引导主语从句。Because引导句子表示因果关系。That引导定语从句修饰breaking strength。Than比较级。
三、考题对应考点
12. 这篇文章主要是讲Manila Hemp与铁的cable相比较的优势以及它的用处的。所以答案选D
13. 强调原则，Anyway, I’ll do my best to have them finished by the next time we meet.教授说她的飞机晚点了，有些作业没有来得及改，所以向学生们道歉。所以选择B
14. 强调原则Now, for some strange reason, many people believe that Manila hemp is a hemp plant. But Manila hemp is not really hemp. It’s actually a member of the banana family— it even bears little banana-shaped fruits.根据manila hemp的名字来看有很多人觉它是一种hemp植物，但是其实不是的，NOW在语气上是在提醒大家注意。所以答案是B
15. 因果原则，出现because ，大家就要注意了。because the bridge was built with steel cables, and steel cables can’t take the salt air unless they’re treated repeatedly with a zinc-based paint. On the other hand,……教授开始说steel cable，然后话锋一转开始赞扬manila hemp其实就是为了反衬steel cable的缺点的。On the other hand是一个信号词，预示着下一话题的展开。所以选择A
16. 转折原则，On the other hand，plant products like Manila hemp, you can drag through the ocean for weeks on end.这一点是manila hemp最好的地方，出现信号词要注意之后的内容是考点，所以选择C
17. 因果原则，because是因果关系的信号词，之后出现的内容是重点because by grouping the fibers you greatly increase their breaking strength—that bundle of fibers is much stronger
And then you take that bundle of fibers and you twist it a little bit, because by twisting it, you increase its breaking strength even more.所以选择BD
听力文本结构框架：
这篇文章主要是讲Manila Hemp与铁的cable相比较的优势以及它的用处的。马尼拉名字来历，以及它有极强的抗腐蚀性及其原因和用法。
