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.
Volunteers in scientific studies sometimes get compensated. The payment can be cash, a gift card or something almost worthless: “It’s amazing what people will do for a lollipop, when they’ve had a few drinks.” Simon Moore is a professor of public health research at Cardiff University in the U.K. And the lollipops were for people who agreed to blow into a breathalyzer, while out on a Friday or Saturday night in Wales—more than 1,800 people agreed to the exchange. The scores covered a wide range of alcohol intake. “So that would go from zero upwards. I think one of the largest scores we had was 120, which is a near death experience.”
The researchers also gave a subset of volunteers a short survey about drinking habits and health risks. Questions like: “How drunk are you right now?” and “How extreme has your drinking been tonight?” And they found that even very drunk respondents felt relatively more sober, if they were surrounded by even drunker people. In other words: our perception of intoxication—and its risks—is relative.
“So this is the point, as you change context, perceptions will change, although the absolute level of alcohol in their system doesn’t change.” The study is in the journal BMC Public Health.
Moore says one way to use this finding is for better city zoning. “In the United Kingdom for example there’s been a big push to put more premises that sell alcohol in the same district, in the same area. And what this does is create a concentration of drinkers. So what we might argue from this is, well let’s try to break that up a little bit.” Have a mix of bars, restaurants, cafes and cinemas,
so drinkers will be around relatively sober people, too, instead of fellow inebriates. Which might encourage drinkers to nurse their drinks…and thus avoid the ER.
Thanks for listening for Scientific American — 60-Second Science Science. I’m Christopher I ntagliata.
