听力填空

本听力材料来自于老托partb，partc，是公认实施有效的听写材料，对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃！

Nopain, no gain.我们的安排是这样的，第一遍用听力软件精听材料（建议做单句听写，听写的时候不要偷看我给的挖空题），然后按照我给的挖空题填关键词，回复后即可看到听力原文和文章精解，我将把难点和易错点oneby one 分析给大家。

回复填空答案格式如下：1____2____3____...et.al.

This room is ______ to electric fish. The eel in the tank behind me can produce a strong ______ of electricity to stun its prey, but most of the fish in here produce only weak electrical ______ that are useful for ________, locating food, and even for communicating.
The knife fish is a good example. This fish navigates using tiny ________in the skin that are sensitive to electrical impulses. The knife fish produces an electrical signal, and the receptors in its skin let it know when the signal it distorted by a tree root, or some other obstacle, so it can go around it.
Fish also use the ability to produce and detect electrical impulses to communicate. They can tell each other what species they belong to, how big they are, and whether they're male or female. We have a tank here that's specially equipped to convert the inaudible signals the fish produce into sounds you can hear when you put on these headphones. I urge you all to listen in when I'm done speaking.
Now have a look at the electric rays. Rays are especially interesting to medical researchers because of the organs they use to produce electricity. These organs contain a chemical that carries signals from one nerve ending to the next, not only in rays, but also in people. By studying these organs, scientists hope to learn more about diseases that interrupt the transmission of impulses from one nerve to another.

最近的听力真是各种动物齐上阵啊，这次讲的是电鱼和它发电的方式。

knife fish 是刀鱼

navigates 说的是鱼在游动的时候操纵自己的身体。

文章的步骤讲的稍微繁杂了些，但是而已简单的做一下笔记，也没什么生词，这篇文章还挺好理解的。

【参考译文】

这个房间是专门用于电鱼。鳗鱼在我身后的坦克，可产生强烈的颠簸的电力击晕猎物，但在这里的鱼大部分生产只有疲软的导航，定位食物的有益的电脉冲，甚至沟通。
鱼刀是一个很好的例子。这种鱼导航使用在皮肤上的微小的电脉冲敏感的受体。鱼刀产生电信号，并在其皮肤的受体，让它知道，当信号扭曲的树根，或其他一些障碍，所以它可以去转转。
鱼也可以使用的生产和检测的电脉冲，沟通的能力。他们属于什么品种，他们可以告诉对方，他们是如何的大，无论他们是男或女。我们有坦克，专门配备的无声信号转换成声音，你能听到，当你把这些耳机的鱼产品。我呼吁大家听时，我做了发言。
现在有一个在电动射线。光线是特别有趣的医学研究人员，因为他们使用机关来产生电力。这些器官中含有一种化学物质，进行信号从一个神经结束下，不仅在光线，而且在人。科学家们通过研究这些器官，希望更多的了解，从一个到另一个神经冲动的传输中断的疾病。

祝大家每天进步一点点！
