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：App IDs Other Battery-Eater Apps
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。
Most smartphone batteries will get you through the day on a full charge. As long as you stay away from apps that are constantly connecting to the network, are poorly written and put a heavy load on the processor.
But which apps are battery hogs? A team of U.C. Berkeley and University of Helsinki researchers is tracking Apple and Android users to find out.
For iOS, music is the most popular app, but the traffic and navigation app Waze is the fastest way studied to drain your battery. Some of the most power-hungry Android apps studied are the Men In Black 3 game and the TeleNav GPS Navigator.
The researchers got their data through a free battery-tracking app they’ve written, called Carat. It’s not the only app that does this, of course. But since it’s been downloaded more than one million times by study participants, Carat has helped the researchers create a chart of the 200 most power-hungry apps for each operating system.
Now if they could just come up with an energy-efficient app that keeps the big new iPhones from bending.
