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，练习记笔记技巧和复述。废话少说，下面开始：
60秒科学：Asteroid-Hunting Satellite Returns from Dead
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。
Like a phoenix, NASA’s dead WISE satellite has been reborn from its own figurative ashes.
WISE was the Wide-field Infrared Survey Explorer. It launched in 2009 to map the universe in infrared light. Unfortunately, it ran out of coolant in 2011 and went into hibernation.
But even without coolant, WISE’s infrared eyes are perfect for spotting dim rocks that radiate heat, not light—such as asteroids. Especially asteroids with Earth’s name on them.
So WISE has been resurrected as NEOWISE. Its new prefix refers to near-Earth objects. And the satellite has just filed its first pictures in its new incarnation.
If NEOWISE finds potentially dangerous space rocks, we have a chance to try to push them off course.
NEOWISE is also looking for asteroids that astronauts could visit. President Obama wants us to commit to a human visit to an asteroid by 2025. And the repurposing of the satellite could help make reaching an asteroid a bit less of a rocky road.
