托福听力长难句分析(十二)

 同学们在学习托福听力的过程中，最头疼的就是句子的理解，尤其是长难句。但是相对于阅读文本来说，托福听力的问题其实是比较简单的，我们在理解句子的时候基本只要考划分句子的主干成分，配合一些短语搭配就可以了，但是关键是要求我们的反应速度要非常的快，我们现在就具体以TPO中的句子为例，来分析一下长难句。(TPO2-L2)

That, if they start at one end of the bridge and they work to the other end, by the time they finish, it’s already time to go back and start painting the beginning of the bridge again, 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.

如果工人们从一头开始一直安装到另一头，到他们完工的时候就要回来重新油漆一遍了，因为金门大桥是由钢丝建成的，钢丝在咸性的空气中非常容易腐蚀，除非反复给钢丝涂上颜料。

On the other hand, plant products like Manila hemp, you can drag through the ocean for weeks on end.

但是像马尼拉麻这样的植物产品，你可以持续好几个礼拜拖着他们穿过海洋。

If you wanna tie your anchor to it and drop it right into the ocean, that’s no problem, because plant fibers can stand up for months, even years, in direct contact with salt water.

如果你想绑上船锚然后把船锚扔进海里，这是一点问题都没有的，因为直接喝与咸水接触的时候，植物纤维能够坚持好几个月甚至好几年。

OK. So how do you take plant fibers that individually you could break with your hands and turn them into a rope that’s strong enough to moor a ship that weighs thousands of tons?

那么你是如何将只手可以拉断的植物纤维做成强韧的能够泊上万吨船的绳子的?

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.

你需要做的是从马尼拉麻里抽出这些长纤维，然后从中拿出几缕揉成一根，通过这样的揉搓可以极大的加强这些纤维的强韧度，这一根的强度比其中任何一缕纤维都要强得多。

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.

之后，再拿揉搓好的那根，再次的捻一下，这样能让其强度变的更大。

And then you take several of these little bundles, and you group and twist them into bigger bundles, which you then group and twist into even bigger bundles, and so on, until eventually, you end up with a very, very strong rope.

再后来，将揉搓好的这些纤维编织成更粗的绳子，一直重复这个过程，知道做出很粗的缆绳。
