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，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：
60秒科学：Neanderthal-Diners-Had-Side-of-Veggies
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。
When it comes to Neanderthal diets, the consensus has been: they ate meat. Lots of meat. But now it looks like Neanderthals chomped on a fair amount of veggies, too.
Researchers have had a tough time discerning the Neanderthals’ diet. They evaluated carbon and nitrogen isotopes in bones, but those only correspond to some general kinds of proteins. Even plant remains in Neanderthal teeth could have gotten there because a tasty animal carcass itself contained traces of a last vegetarian meal.
So the researchers relied on fool-proof evidence they studied Neanderthal fecal remains from a site in southern Spain called El Salt. Neanderthals made it their home about 50,000 years ago.
The researchers analyzed the samples for chemical compounds that can only result from metabolizing cholesterol from meat or from metabolizing plants. All five samples showed evidence of meat consumption. But two revealed the digestion of plants. Meaning that Neanderthals did try vegetation, likely tubers and nuts. The study is in the journal PLoS One.
The scientists intend to use the same technique to examine soil samples at a 1.8 million-year-old site in Tanzania. In the hopes that any remaining poop may deliver an ancestral-diet scoop.
