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。
You wouldn’t think that things as mundane as rust or the eyes of a garden-variety moth would have much in common with advances in sustainable energy. But Swiss researchers report that a way to create highly efficient solar panels may involve photocells incorporating light-absorbing qualities of iron oxide within a structure similar to moth eyes.
The scientists covered tiny particles of tungsten oxide with iron oxide to mimic the way moth eyes gather light. Moth light absorption is highly efficient, for survival reasons because the eyes barely reflect any light, they don’t attract the attention of predators.
And where most solar panels convert light to electricity, these devices use solar rays to split water molecules and produce pure hydrogen fuel. Which deals with the storage problem associated with solar power. The research will appear in the journal Energy & Environmental Science.
Stanford University researchers are likewise exploring ways to bypass electricity generation when splitting water molecules. Their work combines into a single unit the photoelectric cells that gather sunlight and the electrolyzer that produces hydrogen. They published their research last fall in the journal Science.
Both projects are part of an effort to get solar to better compete with cheap fossil fuels. And bring heliocentrism to the power supply.
