PTE Re-tell Lecture 真实讲座练习题:狭义相对论的突破

在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的,中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!


Einstein came up with a number of theories, the first the special theory of relativity, he developed in 1905, and what perhaps is best described as a hurricane of intellectual fever in the spring of 1905 where he was struggling to understand aspects of space and time and he realised that unlike what Newton said, Newton said that space is an absolute eternal unchanging stage in which the events of universe take place. And he said time is something that’s also universal, it’s something that takes forward second after second in a completely uniform absolute way. Time for you is the same time for me is the same for time on Jupiter and Andromeda galaxy. Einstein realised that it isn’t true. He realised that for instance, as you move, time for you slows down relative to somebody who is watching you that is not moving with you. Time is relative. He also realised that space is relative if I’m watching you speed by me, he realised that you look shrunken in space compared to how would you look if you weren’t move. Motion affects time, motion affects space. A completely new understanding of this very basic entities that since the time of Newton we thought were absolutely unchanging. They’re not, they’re relative and they’re changing.
