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：Bouncy Gait Improves Mood
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。
A good mood may put a spring in your step. But the opposite can work too: purposefully putting a spring in your step can improve your mood. That’s the finding from a study in the Journal of Behavior Therapy and Experimental Psychiatry. [Johannes Michalak, Katharina Rohde and Nikolaus F. Troje, How we walk affects what we remember: Gait modifications through biofeedback change negative affective memory bias]
Scientists showed volunteers a list of negative and positive words, like afraid and anxious, or sunny and pretty. Then the subjects had to walk on a treadmill while watching a gauge that moved left or right.
But here’s what the participants did not know: if their stance—for example, slumped shoulders—seemed to indicate a down mood the gauge moved to the left. If their walk was more upbeat, say with swinging arms, the gauge moved to the right. The scientists asked half the subjects to adjust their walking style until the gauge moved to the right, and the other half so that the gauge went the left. Each group quickly learned what adjustments moved the gauge in the desired direction.
Then the subjects had to write down as many words from the list that they remembered. And those who walked with a depressed gait recalled more negative terms, while the ones who were asked to walk in a more upbeat style came up with many more positive words.
Past research has shown that depressed people tend to remember negative words and happier people tend to remember happy words. So this study suggests that the way we walk influences our mental state. And that we can change our state by changing our gait.
