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!
No one’s actually seen the quantum foam. It is an issue that arises from our mathematical investigations, putting together quantum mechanics and Einstein’s theories and trying to make them both apply in the ultra-micro scope domain and the foam arises on really tiny scales, according to math, ten to the minus thirty-three centimeters, the so-called Planck scale. That is billions and billions times smaller than even the scales we can probe the large Hadron Collider, so it’s really tiny scales, but because of the foam, we recognize that the naive melding the gravity quantum mechanics doesn’t work and that’s launched us to develop other approaches like string theory, which try to count the quantum foam and at least on paper string theory is able to do that.
