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：

Can poetry fight air pollution? Turns out it can, with the help of nanotechnology.
Tony Ryan is a polymer chemist at the University of Sheffield. He works with tiny particles of titanium dioxide, which can use sunlight to suck up smog-forming pollution and purify the air.
To demonstrate the effect, Ryan attached a poster 20 meters tall and 10 meters wide to the side of a building in Sheffield on May 14th. The poster is coated with titanium dioxide and can consume the nitrogen oxide exhaust of about 20 cars per day. He argues that every billboard could be similarly treated to suck up pollution at an extra cost of just a few hundred dollars.
The Sheffield poster comments on its own function. Written on it is a new work by poet Simon Armitage entitled “In Praise of Air.” I’ll give him the final words: “on days when thoughts are fuddled with smog / or civilization crosses the street / with a white handkerchief over its mouth / and cars blow kisses to our lips from theirs / I turn the key, throw back the lid, breathe deep. / My first word, everyone’s first word, was air.”
–David Biello
