PTE听力口语练习-科学60秒-Hubble Telescope

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:


Hubble Finds Possible Oldest Object Ever Seen

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。

The Hubble Telescope’s famous “Deep Field” photo showed that seemingly empty patches of space are actually chock full of far-away stuff. The original 1996 picture revealed thousands of galaxies in the apparently blank spot of sky.

Now Hubble has done it again with a new set of what are called “Frontier Fields” images that look farther in the universe than any previous pictures.

These images reveal a treasure trove of previously unseen galaxies, including one that may be among the most distant objects ever seen. The candidate galaxy, called Abell2744 Y1, appears to lie more than 13 billion light-years away, meaning its light has taken 13 billion years to reach us. This object appears to have formed when the universe was only about 650 million years old.

Such primordial galaxies may be different from the types that tend to form now. For instance, Abell2744 Y1 is about 30 times smaller than our Milky Way, yet it’s creating 10 times as many stars as our galaxy does. That is to say, it did, when the universe was new.
