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.
Global warming deniers love to point to cold or snow as evidence against climate change. Like Oklahoma Senator James Inhofe. Remember last year, when he tossed a snowball in Congress? “You know what this is? It’s a snowball. It’s just from outside here. So it’s very, very cold out, very unseasonal. So here, Mr. president, catch this.” With that, he offhandedly disproved decades of climate science. To some people at least.
But such cold-influenced-denial may be playing out across the U.S., in particular in Appalachia and the South. Because it turns out those areas have had lots of record low temperatures in the last 12 years. And they’re also by and large the same parts of the country that have high numbers of global warming skeptics. So researchers have a theory that personal experience with cold snaps could be trumping scientific facts. The analysis is in the Proceedings of the National Academy of Sciences.
Study author Robert Kaufmann, an environmental scientist at Boston University, says the way around this might be to put climate data in terms people understand: money. “We should propose a simple bet to climate skeptics. And that is: For every new record high temperature at a weather station, you pay us a dollar. And for every new record low temperature, we’ll pay you a dollar.”
Or, he says, think of climate change as a slot machine, especially with the president-elect. “He’s run casinos. So you can kind of think of climate like a climate casino. If you were a casino owner and you had a machine that was constantly paying out more record high temperatures than more record low temperatures, you would look into that machine. Something’s wrong with the machine. And that’s what the climate machine has been doing.”
However you think about it, Kaufmann won’t be betting. “I got no dough, man, I’m an academic.”
