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：Brain-Training-Games-May-Not-Improve-Overall-Intelligence
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。
Brain-training games claim that testing memory, attention and other forms of cognition will improve one’s overall intelligence and brain function.
And it’s probable that such games do improve performance on a specific task. But it’s unlikely that there’s a general improvement. That’s according to a study in the Journal of Neuroscience.
Sixty men and women played a computer game that tested their ability to withhold an action. The subjects saw a go signal an arrow pointing either left or right and they had to press a key, as quickly as possible, that corresponded to the signal’s direction. But 25 percent of the time a beep sounded just after the arrow appeared which meant to not press the key.
Compared with a control group that never got the inhibitory beep, the game players’ exhibited heightened levels of activity in regions of the brain that control inhibitory action and emotion. But researchers found no change in other areas, for instance those that support working memory.
The researchers write that while brain-training games might temporarily improve a specific task, in this case inhibitory control, they may not lead to a general improvement in overall brain function. But they may still be fun.
