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：”Extremely Large Telescope” Breaks Ground
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。
High on a Chilean mountaintop, scientists have broken ground on what will be the world’s largest telescope. Called the European Extremely Large Telescope, or E-ELT, the observatory may even be sensitive enough to spot signs of extraterrestrial life on alien planets—if there is any, of course.
The E-ELT’s gigantic 39-meter-wide primary mirror will capture 15 times more light than any existing optical telescope, and its images should be 16 times sharper than the Hubble Space Telescope’s.
That kind of view could reveal exoplanets changing color with the seasons, suggesting the presence of vegetation. The scope might also reveal planetary atmospheres with chemicals consistent with life, such as oxygen, ozone, carbon dioxide and methane.
The European Southern Observatory is building the telescope. On June 19th they blasted off the top of the Cerro Armazones mountain to create a plateau for the facility.
The 3,000-meter-high site offers incredibly clear skies with a minimum of atmosphere to distort the images. The huge construction project is set to finish in 2023. Then, just maybe, we’ll catch a glimpse of the activities of any cosmic neighbors.
