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。悉尼文波雅思PTE培训学校专门为澳洲，尤其是悉尼、墨尔本的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。
Thousands of energetic particles called cosmic rays fly right through our bodies every second without us ever noticing. Now scientists want your help to track this radiation from space in a massive citizen science project—by using your smartphone.
Physicists don’t know for sure where cosmic rays come from, but they suspect supernovae and powerful black holes are involved. Although we’re bombarded with the particles, the very highest energy cosmic rays are rare. Studying them has therefore been difficult. But it turns out that smartphone cameras are actually good at detecting them.
When these especially energetic rays hit Earth’s atmosphere they create a shower of other charged particles. These particles hit a camera’s sensor, resulting in one bright pixel against a dark background. If enough phones in the same area see particles, scientists can recreate the cosmic ray’s path through space.
You can take part in the project through an app called CRAYFIS (for Cosmic Rays Found in Smartphones).
CRAYFIS only operates when a phone is plugged into a power source and not otherwise being used, so it will not drain your battery. Imagine: between Candy Crush and Facebook sessions, your phone can help unravel the mysteries of the universe.
