PTE Re-tell Lecture 真实讲座练习题:标准模型是不是宇宙的最终理论?

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 standard model can’t be the final world for a couple of reasons. One it doesn’t include gravity must be part of the story, but there’s something else as well. When we look at the standard model of particle physics, the equations involve certain numbers, that we have input from experimental measurements, numbers like the mass of electrons, the mass of the quarks, the strength of electromagnetic force, the strength of nuclear forces, all these numbers. We understand the numbers quite well, they come from experimental measurements, but one day, we hope to be able to explain those numbers. Not just input them from experimental data from observations. And that new theory, that’s able to explain those numbers that today or simply input into the standard model, that is the goal, that’s what we’re seeking to find.
