PTE听力口语练习-科学60秒-Computers and Movements

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:

How Computers Affect Our Movement


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。

For most people, learning to use a computer mouse comes quickly. Our brains match hand movements with the cursor on the screen. Now we know that this connection can be easily generalized to other kinds of computers and mouse movement°™like how some saxophone players can switch seamlessly to a clarinet.

Scientists had seasoned computer users and novices move a cursor while their hand was hidden from view. Experienced users quickly generalized what they learned about the cursor’s movement to perform other kinds of functions with that cursor. Novices took longer to catch on. Not too surprising.

But then the researchers had a second group of novices use a mouse to play a video game for two hours a day. In just two weeks they were able to generalize their mouse skills to rival experienced computer users. For instance they could control other mouse types, and do it on different Macs and PCs, with different kinds of screens. The study is in the journal Current Biology.

The researchers say this study shows how using a mouse can affect the neural representation of our movements, and how natural it can feel. Apparently, our long history of tool use comes in°≠handy.
