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,墨尔本悉尼文波雅思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!
The special theory of relativity was developed by Albert Einstein in Spring of 1905 and the space have a perhaps 5 intense weeks of thought, where he rewrote our understanding of space and time. Newton had given us an understanding of space and time back in late 1600s which is very intuitive. It’s the way we all think about space and time. Here is a space, it’s just this environment where things happen and time is this relentless thing that ticks forward on our watches, our clocks. Taking us moment after moment, second after second into the future in a completely uniform, absolute and unchanging way. In special relativity, Einstein said that’s not right. He said space and time can change depending upon how you move. He showed that if you’re moving relative to somebody else, time for you slows down. And these kinds of revolutionary ideas are not simply esoteric, pen and paper type understandings of the universe. You can take a little particle called muon, which if it’s sitting in front of you will self-destruct in about of a millionth of a second it will fall apart. You take that particle and you make it go fast, one of these particle accelerators, it zips around near the speed of light. Because it’s moving, time for it slows down. It doesn’t just live for a millionth of a second. It lives for a second or longer, a million of times longer than it would if it was sitting in front of you. If you can put a person in one of these accelerators, they wouldn’t live 80 years, they might live 80 million years as we’re watching them because time for them slows down.
