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，练习记笔记技巧和复述。

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 Steve Mirsky.
Back in 2011 member countries of the World Health Organization, the WHO, came up with a plan to cut mortality from noncommunicable diseases 25 percent by the year 2025. The program was thus called the 25 X 25 Initiative. And it identified various health risk factors, such as smoking, high blood pressure, diabetes and a sedentary lifestyle. What the Initiative did not include as a risk factor for poor health was poverty.
An international team of researchers thus decided to look at poverty as a possible driver of noncommunicable illness. They pored over data from 48 previously published studies that included socioeconomic information. Together these studies included some 1.75 million subjects from seven high-income countries in the WHO. And the research team found that being poor was more dangerous than obesity or high alcohol intake. The study is in the journal The Lancet.
The results were reported in terms of years of life lost between the ages of 40 and 85. Being a current smoker was associated with 4.8 years of lost life, diabetes with 3.9 years and physical inactivity with 2.4 years. Being of low socioeconomic status was almost as bad as inactivity, with 2.1 years of lost life. High blood pressure only accounted for 1.6 years lost and high alcohol intake was good for—or bad for—0.5 years gone.
Because of these findings, the researchers wrote that the results “suggest that socioeconomic Circumstances…should be treated as a target for local and global health strategies, health risk surveillance, interventions, and policy.” In other words, part of treating disease is treating poverty.
Thanks for listening for Scientific American — 60-Second Science Science. I’m Steve Mirsky.
