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:
Warmer Waters Make Weaker Mussels

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。
When it comes to mussels, bigger isn’t necessarily better. Tiny fibers called byssals enable mussels—the shellfish kind—to anchor themselves to coastlines despite crashing ocean waves.
But new research shows that the attachment fibers weaken in warm water. A temperature rise of 15 degrees Fahrenheit lessens fiber strength by 60 percent, possibly causing them to fail completely. As climate change raises ocean temperatures, mussels may be forced to cooler waters.
Emily Carrington of the University of Washington presented the research at the meeting of the American Association for the Advancement of Science in Boston:
“Researchers have dissected mussel beds and found, I think, upwards of 100 different species. So if the mussels go it really changes that community.
“We also eat mussels and so there’s applications in aquaculture. The way they grow mussels, is the mussels have to remain attached to the ropes on their long lines. So if the mussels fall off before the farmers return to reap their harvest, then they’ve lost a lot of money.”
