PTE听力口语练习-科学60秒:Cats And Robots

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:

PTE听力口语练习-科学60秒:Cats And Robots have evolved in leaps and bounds in recent years, but they still cannot safely leap or bound.

They have to move carefully.
If a robot were to fall from an elevated surface, for the most part it would crash down like a bag of rocks.
Not ideal if that robot is on a rescue mission.

So a team of Georgia Tech researchers wants to produce robots that are more agile, by making them literally cat-like.

Specifically, the plan is to create a robot that can emulate a cat’s uncanny ability to calculate the best landing angle, adjust its body midflight and land on its feet.
So far the research team has been able to build a robot capable of computing landing angles during test falls.
They hope to eventually give the robots joints that can twist or flip their bodies to stick the landing, regardless of the angle.
To do that, they’ll need better motors and servos.
The ones available today are not fast enough to sufficiently adjust a robot’s body in real time.
Baby steps. David Belle didn’t develop the city scape acrobatic activity known as Parkour overnight.
And the typical house cat has had tens of thousands of years to perfect the soft landing.
bound:[baʊnd]   n.范围,跳跃
acrobatic:[ækrə’bætɪk]   adj.杂技的
