PTE听力口语练习-科学60秒- Brain Functions of Navigation

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。悉尼文波雅思PTE培训学校专门为澳洲,尤其是悉尼、墨尔本的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:


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。

From the backseat of a cab, the moves a driver makes may at times seem, let’s say, daring.
In fact, cabbies may actually be better, more agile drivers than the rest of us.
Because they know their streets so well.
Previous research found that the hippocampus in the brain of a typical cab driver is enlarged.
That’s the part of the brain used in navigation.
But now a study confirms that learning detailed navigation information does indeed cause that part of the brain to grow.
The findings are in the journal NeuroImage.
Researchers had young adults who were not regular gamers play a driving simulation game.
Some practiced maneuvering the same route 20 times, while other players were confronted with 20 different routes.
The participants’brains were scanned before they performed the simulated driving and again after.
Researchers found that subjects who kept repeating the same route increased their speed more than those driving multiple routes.
The singleroute drivers were also much better able to put in order a sequence of random pictures taken along the way and to draw a map of the route.
The investigators also found increases in the singleroute drivers in the functional connectivity between the hippocampus and other parts of the brain involved with navigation.
And the amount of change was directly related to the amount of improvement each participant displayed.
These findings may explain why your Uber driver can eventually get you from point A to point B,
but may lack the seemingly effortless mental flexibility that a yellow cabbie displays on the streets.
Veterans have been there, done thatand their brains show it.
