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!
Yes, the reason why there would be other realms out there, that would be in some sense copies of the universe that we know about here, you can argue from a very simple consideration. If you look in any finite region of space, matter can only arrange itself infinite many different configurations. Think of a deck of cards, when you shuffle the deck of cards, the cards will come out in different orders, but there are only finitely many different orders of the cards that are possible, which means if you shuffle that deck enough time, say infinitely many times, the order of the cards sooner or later has to repeat. Similarly, if space goes on infinitely far then the arrangement of particles region by region by region sooner or later has to repeat too. What does that mean? Well, I am just an arrangement of particles, you are just an arrangement of particles, the earth and sun that’s just the arrangement of particles, so if the arrangement of particles here repeat some place out there. Then there is a copy of me out there, copy of you, copy of the earth and sun and everything else in another universe way out there, parallel to ours.
