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：
Wrinkled Fingers Are Not Slippery When Wet

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。
Volunteers were more adept at handling wet objects when their fingertips had gotten waterlogged to the point of being wrinkled than when their fingers were dry. Karen Hopkin reports
After a long bath, your fingers and toes come out all wrinkly. You may have wondered why your skin would go and do such a thing. Now a study shows that puckered digits give us a surer hold on objects that are slippery when wet. This gripping discovery appears in the Royal Society journal Biology Letters. [Kyriacos Kareklas, Daniel Nettle and Tom V. Smulders, Water-induced finger wrinkles improve handling of wet objects]
It might seem like magic, or maybe osmosis, that sets your fingertips rippling after being submerged for awhile. But it’s actually an active process that’s controlled by the same part of the nervous system that regulates your heartbeat, breathing and even sweat. So, underwater wrinkling is something your body does on purpose.
To explore the potential advantages of waterlogged fingertips, researchers asked volunteers to move a bunch of marbles from one bucket of water to another. Sometimes their fingers were wrinkled, sometimes they were smooth. The results: subjects were more nimble with the wet marbles when their fingers were wrinkled.
Could be that this mechanism gave our ancestors a leg-up, or hand-up, when it came to grabbing wet fruit or dashing through the rain. Now science has shown that wrinkled fingers also help keep us from losing our marbles.
