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：Mobile-Phones-Carry-Owners-Microbiomes
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。
This year, the number of mobile phones on cell networks is expected to surpass the Earth’s population. “More people now own cell phones than actually have access to working toilets.” James Meadow, a microbial ecologist at the University of Oregon. Hidden in the data is the reality that some people work on their phones¡on toilets.
If that grosses you out, consider this: “So it turns out we’re just really leaky animals. We just, we leave our bacteria everywhere we go.” Including, of course, our phones.
Meadow and his colleagues took a census of the bacteria on thumbs and index fingers of 17 volunteers and on their smartphone touch screens. Overall, they ID’ed over 7,000 types.
Looking at just the most common bacteria, those that appear more than 0.1 percent of the time, they found an 82 percent similarity between the microbiomes of fingers and phones. Meaning our phones are a pretty good mirror of ourselves, microbially, at least. The results appear in the journal PeerJ.
“We have always been covered in bacteria¡ and we will always be covered in bacteria.” So the fact that our phones are also covered in bacteria is no reason for concern. In fact, the researchers say that mobile phones may hold untapped potential as personal microbiome sensors. App developers, take note.
