PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书（PLUS，Testbuilder, OG）之外，就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。墨尔本文波雅思PTE培训学校专门为墨尔本，悉尼PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture，PTE听力口语-科学60秒-Frosty Moss练习记笔记技巧和复述。废话少说，下面开始：
60秒科学：Dark Living Led to Mighty Mouse Hearing
听力内容：
60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American – 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
The three blind mice should have heard the farmer’s wife coming. Because a new study shows that when mice can’t see, their hearing improves.
Researchers kept healthy adult mice in total darkness for a week. When the mice got the lights back on, their vision quickly returned to normal—but their hearing was better.
The researchers also scanned the part of the mouse brains that processes auditory signals while they played a set of tones. In the temporarily blind mice, neurons reacted to the notes more quickly. The nerves also picked up softer sounds and were better at distinguishing between different tones.
The improved hearing wore off after a few weeks, but researchers are investigating ways to make it permanent. The study is published in the journal Neuron. [Emily Petrus et al., Crossmodal Induction of Thalamocortical Potentiation Leads to Enhanced Information Processing in the Auditory Cortex]
Previously, the neurons in this part of the brain were considered incapable of changing after childhood. But the findings show the brain is more flexible than we thought. And they also suggest that if you can’t hear me clearly, try turning out the lights.
