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：Electronic Skin Could Bring Touchy Robots
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。
Our skin tells us about our surroundings by detecting temperature, pressure and other external conditions. If a pot handle is too hot to touch, we can feel this heat before burning our hand.
Robots may someday have this protection too. A team of researchers at the University of California, Berkeley, has developed a large-area sensor network integrated into a thin plastic film that acts like an electronic skin. They demonstrated the concept with an e-skin sample about the size of a postage stamp that lights up in the specific places it’s touched. The work is in the journal Nature Materials. [Chuan Wang et al., User-interactive electronic skin for instantaneous pressure visualization]
The harder the e-skin gets pressed, the brighter the light.
The researchers envision that flesh and blood users could have an e-skin smart bandage that monitors wounds. A large sheet of the material covering the wall of a room could even operate like a display screen. And a robot with such a surface could more effectively interact with its environment.
Of course, we don’t want our robots to be too sensitive. Then they might balk at cleaning up nuclear waste or spending years at a time all alone on Mars.
