PTE听力口语练习-科学60秒- bat sensor

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:


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。

Hall of Famer Ted Williams once famously commented that hitting a baseball is the hardestthing to do in sports.
Although Williamsa .344 career hittermade it look easy, he had a point.
Hitting a round ball with a round bat squarely is difficult.
It’s also an excellent example of some very entertaining applied physics.
No surprise then that professional baseball players are turning to science to improve theirmultimilliondollar strokes.
Some approaches focus on the neuroscience of hittingthe deep internal brain mechanismsbehind seeing the pitch and reacting to it.
But for more info about the swing itself, a sports tech company called Zepp Labs makes asensor that can help break down those mechanics.
The sensor sits in the knob of the company’s socalledSmart Batand uses twoaccelerometers and a threeaxis gyroscope to measure bat speed, hand speed, attack angleand other factors.
The sensor, which weighs only about eight grams, sends this info to a smartphone app viaBluetooth.
The app can then use this data to have an onscreen avatar reenact the swing, in the hopethat the batter can pick up some details and make the necessary adjustments.
Zepp’s sensors can also be fitted to golf clubs and tennis rackets.
Never one to mince words, Ted Williams also once said that pitchers werethe stupidest peoplealive.”
Hmm, maybe somebody could come up with a smart baseball to help them.
Against any Ted Williamses out there, anyway.
