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：Oenophiles-Confirm-Fruity-Flavors-Finish-First
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 lore among wine aficionados is that fruity flavors tend to finish quickest on the palate, whereas oaky flavors linger longer.
And then when you go to the scientific literature, you find out that really there haven’t been scientific studies done on it. Carolyn Ross, a sensory scientist at Washington State University.
She and her colleagues investigated the claims. They identified four flavor compounds common in white wine, which give floral, fruity, mushroomy and oaky notes. They then studied the compounds in what’s known as a model wine: Meaning that it had alcohol in it, it had some sugar, some acid in it, but it wasn’t actually wine.
They added the compounds one at a time to their model wine, and asked trained tasters to clock how long it took flavors to fade. Fruity did indeed finish first lasting a minute and a half. The others took 30 seconds longer to fade. And even when mixed with the other flavors, fruity still finished first so the lore was right.
The study appears in the journal Food Quality and Preference.
As for home tasters? Pay attention to the finish, perhaps time it, if that’s your thing. It does happen to be ours.
