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：Eye-Catching Adapter Makes Smartphone Ophthalmic Screener
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。
Smartphone cameras have turned the selfie into an art form. And soon your selfie may be able to warn your doctor about a serious problem with your eyes, without a trip to the ophthalmologist.
Stanford University School of Medicine researchers are developing inexpensive adapters that let smartphones take high-quality images of the eye. Not just the lens in front but the retina in back too. With no need for eye drops that dilate your pupils for hours.
The research team is studying the quality of images taken using the adapters and their ability to track eye disease in patients with diabetes. This work was published online in the Journal of Mobile Technology in Medicine.

Right now, prototype adapters cost about $90 to make and are available only to other researchers. But if the adapters work as promised, patients could snap digital pictures of their eyes and e-mail them to a doctor. That’s a convenience for most of us, but a necessity for people living in remote areas with poor access to any local ophthalmic care.
And it could turn your iPhone into an “eye” phone.
