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：
Kids Who Exercise Don’t Sweat Tests
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。
Hey kids, here’s a good reason to work up a sweat: when young people exercise for an hour each day it also helps boost their brain power. That’s according to a study of more than 200 kids in the journal Pediatrics. [Charles H. Hillman et al: Effects of the FITKids Randomized Controlled Trial on Executive Control and Brain Function]
Seven, eight and nine year-olds were randomly selected to enroll in an after-school exercise program or be placed on a wait list. The exercisers performed much better on intellectual tests. And there was a dosage effect: kids who spent more time in the program performed even better than kids who were enrolled in the program but had spotty attendance.
Government guidelines already recommend that everyone aged 6 to 17 engage in an hour or more of moderate- and vigorous-intensity physical activity daily, but many kids still do not meet this threshold. Better cognitive capabilities could be a selling point for more exercise.
The study could not tease apart how much increased physical fitness versus social interactions in the exercise program may have contributed to better accuracy on cognitive tasks. But other work has suggested that exercise is better for cognition than social interactions alone. Regardless, a workout that offers both is a win-win.
