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，练习记笔记技巧和复述。废话少说，下面开始：
60秒科学：Poor-Diabetics-Suffer-More-Amputations
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。
Diabetics who live in poor areas in California are far more likely to suffer an amputation than are diabetics in wealthier neighborhoods. So finds an analysis in the journal Health Affairs.
The study reveals that patients in low-income zip codes were up to 10 times more likely to lose a leg or foot than diabetic patients in more affluent zip codes. In poor areas like Compton, as many as 10.7 out of 1,000 diabetic adults ages 45 and older wound up losing a lower limb due to diabetes complications. In wealthier areas, including Malibu and Beverly Hills, no more than 1.5 diabetics per 1,000 lost a limb to the disease.
Fewer healthcare options for poorer patients and their providers may have contributed to the disparity, the researchers write.
The diabetes patients most at risk for amputations were male, older than 65, black and non-English speaking.
When blood sugar and other health metrics are carefully monitored and controlled, diabetes amputations are much more preventable. Otherwise, diabetes can lead to impaired circulation in the feet and nerve damage. Those conditions, in turn, can keep patients from noticing developing infections.
The researchers advise daily foot washing and checks for cuts to help keep patients on their feet. And improved health care access for communities most in need is a must.
