PTE听力口语练习素材:科学60秒-Supernova

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:Pre-Adolescent-Astronomer-Spots-Supernova

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。

Not many people can boast of discovering a new celestial wonder, let alone doing so before puberty. But 10-year-old Nathan Gray of Nova Scotia has done just that: Gray is officially the youngest person ever to identify a new supernova.

Gray, with the help of his father, used the local Abbey Ridge Observatory to spot the exploding star on October 30th. His find was confirmed as a bona-fide supernova last week by Italian astronomers. They took spectroscopic measurements that showed the newfound object had the wavelength signatures of a supernova.

Supernovas happen when giant stars run out of fuel for nuclear fusion and collapse in on themselves. The resulting giant explosions are so bright they are visible from distant galaxies.

Nathan Gray found his supernova in the constellation of Draco, where he noticed a new bright star that hadn’t been there in older images.

Nathan comes from a space-minded family. In fact, he stole his new title from his older sister, Kathryn Aurora Gray, who had held the record for youngest person to discover a supernova. Looks like the family has multiple young stars.
