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：

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。
High blood sugar levels are a risk factor for type 2 diabetes.
Doctors today have only general dietary recommendations for how to control those levels, because there’s no real way to predict what’s called the post–prandial glycemic response–that is, just how your particular blood glucose level will be affected by what you eat.
But a new study may be the start of making glucose controlling food recommendations more personal.
Scientists in Israel followed 800 nondiabetic adults over one week, checking their blood glucose levels every five minutes.
The participants got a full medical workup, including a stool sample to analyze their gut microbiome.
The participants logged the food they ate, their exercise and their sleep.
They chose their own food except for one meal a day, which was one of four standardized options.
The result? “The blood sugar response of different people to identical meals can be hugely different.”
Eran Segal of the Weizmann Institute of Science.
Segal and his colleagues found that one person’s blood glucose might spike in response to a particular food, while that same food would actually lower another person’s.
The study is in the journal Cell.
The researchers then developed an algorithm that could predict an individual’s blood sugar responses to various meals.
“We link nutrition in a personalized manner to human risk to develop elevated blood sugar levels and their many complications.”
Eran Elinav of the Weizmann Institute, who also took part in the study.
“As scientists we often deal with very basic questions, but in this work we are very happy to also introduce a potential that if further developed would allow to benefit the health of millions across the world.”
