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
If you’re like me, you know that multitasking does not always save time. 如果你同我一样，你就应该知道多任务处理并不总能节省时间。
You slow down or make mistakes that require fixing. 你会降低速度或者会犯需费时修改的错误。
But maybe I’m just doing the wrong things. 但也许我只是选错了需要处理的任务。
Because a new study shows that people on a stationary bike pedaled faster when they simultaneously tackled some sort of mental test. 因为一项新研究表明当人们在静止不动的自行车上进行心理测试时踩踏板的速度会更快。
Even the researchers were surprised by that result. 甚至研究人员也对这样的结果感到惊讶。
They had originally set out to demonstrate what other studies have shown: 他们原本是打算证明其他的研究结果：
that when people try to do two things at once, they do both more poorly. 即当人们一心二用做两件事时结果都不是很好。
Their counterintuitive finding is in the journal PLoS ONE. 他们这项违背本意的研究已在《公共科学图书馆期刊》上发表。
In the experiment, subjects were asked to complete various cognitive jobs that ranged in difficulty. 在实验中的受试者们被要求进行一系列依难度等级划分的认知任务。
everything from saying go when they saw a blue star on a projection screen to remembering a long list of numbers and then repeating them back in reverse order. 在开始后看到投影屏幕上出现一颗蓝色星星时，受试者们需要记忆一长串数字，之后以倒序的方式复述。
They tackled these tasks once while sitting in a quiet room and again while on the bike. 他们一开始是在一间安静的房间中，而后又在自行车上再进行一遍。
Turns out, cyclists rode 25 percent faster when they were distracted by some mental gymnastics—but only when the tasks were relatively easy. 结果显示骑脚踏车的受试者在被脑力测试分心时，他们的骑行速度却快了25%—但仅限任务相对简单的情况。
When confronted with tough brain-teasers, their cycling speeds were about the same as when they had nothing in particular to think about. 而在思考较难的脑力问题时，他们的骑行速度和平时没有特别问题考虑时几乎一样。
And in case you’re wondering, the participants’ cycling neither helped nor hindered their brain function. 而且如果你正在考虑，受试者的骑行既没有帮助也没有妨碍他们的大脑功能。
The findings could point toward new programs in which we get better workouts simply by using our heads. 这样的结果可能会带来仅通过大脑获得更好锻炼效果的新项目。
