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。悉尼文波雅思PTE培训学校专门为澳洲，尤其是悉尼、墨尔本的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：
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 is Scientific American — 60-Second Science. I’m Christopher Intagliata.
Perhaps you’ve seen the famous TED talk about so-called power poses. It encouraged viewers to change the course of their lives by assuming what are thought of as dominant postures.
“So you make yourself big, you stretch out, you take up space. You’re basically opening up. It’s about opening up.” That’s Harvard researcher Amy Cuddy. Her talk is the second most-watched on the TED site: 37 million views. The 2010 study by Cuddy and colleagues that inspired the talk stated that striking power poses can affect your hormone levels, and in turn, your appetite for risk. Fake it til you make it, she said. Strike a pose, and “it could significantly change the way your life unfolds.”
Problem is: that memorable advice looks suspect.
Because several studies, with many more participants, have tried to replicate the original results, and failed. The most recent attempt involved 247 male college students—nearly six times more volunteers than were in the original study. And the new study found that holding poses—dominant or otherwise—had no significant effect on testosterone and cortisol levels, or on risk-taking either.
“The evidence is piling up that this might not be the most fruitful research track.” Kristopher Smith, an evolutionary psychologist at the University of Pennsylvania. “These power pose effects aren’t very reliable—and might not even be there.” The analysis is in the journal Hormones and Behavior.
Despite these replication failures, Amy Cuddy, of the TED talk, stands by her finding. She still says that, even if holding a pose doesn’t affect your hormone levels, it still makes you feel more powerful. But this new follow-up study failed to find even that effect. And its authors aren’t alone in their skepticism. One of the authors on the original 2010 power pose study, Berkeley researcher Dana Carney, announced a few months ago that she no longer believes power pose effects are real. She doesn’t teach them. She even discourages studying them. So this could be the rare case where more research is not needed.
