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：Docs Should Wash Stethoscopes between Patients, Too
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。
During a physical exam, doctors pick up a lot from their patients. Including that patient’s bacteria. To keep infections from spreading, physicians try to always wash their hands between exams. But they don’t always scrub their stethoscopes.
To see just how much bacteria these instruments gather, doctors examined 71 patients, using sterile stethoscopes and gloves. After each exam, researchers collected samples from the stethoscope’s surface and tube, as well as four parts of the physician’s gloved hands: the fingertips, backs and two locations on the palm.
The fingertips became by far the most bacterially contaminated. But the runner-up was the stethoscope’s surface, which gathered more microbes than the palms or the backs of the hands. The study is in Mayo Clinic Proceedings. [Yves Longtin et al., Contamination of Stethoscopes and Physicians’ Hands After a Physical Examination]
Although fingertips picked up more than five times as much bacteria as stethoscopes did, doctors reduce that contamination before seeing the next patient by cleaning their hands. According to this study’s authors, stethoscopes should get the same treatment. Then the only thing to fear is the stethoscope’s icy temperature.
