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!
Work that I focused on some years ago had to do with what would happen if in the extra dimensions of string theory, space would rip apart. Now that ripen space from Einstein’s perspective would be a singularity. His math could not cope with it. We use the mathematics of string theory to analyse that terrain space and found we could analyse it, perfectly well and there is no catastrophe and in fact, we found that the tail that would repair itself in the manner that allowed the fundamental shape, the so-called topology of the extra dimension to change. So not only could we handle the singularity in string theory, we found that they let two exhausted processes where the shape of space underwent a kind of change that Einstein would not thought it’s possible, so it’s a very fruitful way of curing a problem and coming to a sparkling new conclusion.
