PTE听力口语练习-科学60秒: Rocket-Precision Landing

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:

Space,the final frontier, is also the most expensive one.

Reaching Earth orbit typically costs between ten-to twenty-thousand-dollars per kilogram.
That’s because rocketry is the only form of transportation where you throw away your vehicle once you’ve reached your destination.
But that might change as soon as January of next year, when Space Exploration Technologies, also known as SpaceX, plans to launch a rocket into space, then bring the rocket’s first stage back for a precision landing.

After launching a payload on a resupply mission to the International Space Station,Space X’s Falcon 9 first stage will deploy hypersonic stabilizing fins and fire its engines four times, steering itself to an upright touchdown on a robotic barge floating in the Atlantic Ocean.

Think of a 14-story building moving faster than a kilometer per second.
And now imagine slowing it down, balancing it on a jet of rocket exhaust and landing it with an accuracy of 10 meters on a target smaller than a football field.
It won’t be easy—company representatives only give the precision landing 50–50 odds.
But if successful, SpaceX’s audacious test could soon lead to cheaper, fully reusable rockets that make the final frontier not quite so financially challenging.
