PTE Re-tell Lecture 真实讲座练习题:物理学家发现中微子

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!

And neutrinos have been with us since they were hypothesized way back in the 1930s and it’s interesting to see where the idea even came from in the first place basically, people were looking at reactions. Wolfgan Pauli was studying certain reactions were a particle would decay to other particles. And he found that the energy of the debris created by the decay was a little bit less than the energy of the particle that they were beginning with. Missing energy, he said, look, energy is conserved. There must be another wispy particle that were missing that’s carrying away that missing energy. So the hyp…….
