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’s 60-second Science, I’m Steve Mirsky.
Got a minute?
“There are sort of three main ways that our species has developed to break down foods, or process foods, in a primordial way. And that is by cooking, by fermenting foods and by drying them or desiccating them.”
Paul Breslin, professor of nutritional sciences at Rutgers University in New Jersey. He’s also a member of the Monell Chemical Sciences Center in Philadelphia.
“And the first two, cooking and fermenting, are older than our species is. Homo sapiens sapiens came about in the presence of fire. And probably eating some fermented foods, since that happens spontaneously.”
Breslin spoke February 20th at a press briefing at the annual meeting of the American Association for the Advancement of Science in Boston.
“So I think that we may be unique among the apes in that we can detect when a food has been cooked or fermented. And that this allows us to identify the benefits of those, which is that they’re detoxified, they have greater available nutrients, and they are, in the case of fermented foods, going to have probiotics—or good microbes that we want and need in our intestines in order to survive in the world.”
“The second leading cause of death of children on Earth today is diarrhea, following pneumonia, which is number one. And that diarrheal disease is in fact the most common disease on Earth in humans. And that eating fermented foods, properly fermented foods of any kind, can in fact deliver probiotics, which help prevent these diseases. And I believe could in fact save lives if they were more commonly adopted in society.”
Thanks for the minute for Scientific American — 60-Second Science Science. I’m Steve Mirsky.
