跟读练习: Where Did the Antimatter Go? - 通过视频学习英语口语

正在创建课程...
1
Did half of the universe disappear?
2
The Big Bang should have created equal amounts of matter and antimatter.
3
When the two meet, they annihilate each other and transform back into pure energy.
4
But if there had been equal amounts of matter and antimatter, we'd see a universe made 50% out of antimatter or nothing but a sea of radiation.
5
So where did it all go?
6
If there were regions with antimatter stars and galaxies, they would clash against regions of matter,
7
resulting in huge gamma-ray bursts that would be detected by telescopes, and they haven't.
8
So some scientists think there must have been an imbalance at the beginning, for every billion particles of antimatter, a billion and one of matter.
9
If they really were created in equal amounts, then the laws of physics must treat matter and antimatter differently.
10
We've seen hints of this, matter-antimatter pairs of baryons, the building blocks of protons and neutrons decay in slightly different ways.
11
But such tiny differences aren't enough to explain where the antimatter went.
12
That's why scientists are willing to pay over 60 trillion dollars to produce a single gram of antimatter.
13
The more we probe their tiny asymmetries, the closer we get to learning how anything exists at all.

宇宙中的反物质去哪儿了?

你有没有想过,宇宙诞生时的大爆炸本应产生等量的物质和反物质,可它们相遇就会湮灭成能量。但我们现在看到的宇宙并非一半反物质或全是辐射,反物质究竟去了哪里?视频里提到,若存在反物质星系,它们与物质碰撞会产生伽马射线暴,可望远镜并未探测到。科学家猜测,或许一开始就有微小不平衡,每十亿个反物质粒子对应十亿零一个物质粒子。还有人认为物理定律对两者的作用不同,比如重子衰变的细微差异,但这仍不足以解释反物质的消失。甚至有科学家愿意花费超60万亿美元制造一克反物质,只为探究其中的不对称性。

实用表达与搭配

  • annihilate each other:相互湮灭(描述物质与反物质的作用)
  • gamma-ray bursts:伽马射线暴(天文学中的重要现象)
  • baryons:重子(质子和中子的组成部分)
  • tiny asymmetries:微小的不对称性(用于解释宇宙物质的存在)
  • probe the differences:探究差异(科学研究中的常用表达)

你的影子跟读挑战

想要提高英语发音和口语流畅度,影子跟读(shadowspeak)是个好方法。现在就打开这段视频,跟着音频进行影子跟读练习。先听一句,暂停后重复,注意模仿语调、节奏和重音。重点练习“annihilate each other”“gamma-ray bursts”等短语,感受连读和爆破音的处理。坚持每天10分钟,利用影子跟读网站(shadowing site)的资源,你的英语表达会越来越自然。记住,影子跟读不仅能提升发音,还能帮助你更好地理解复杂句子的结构,赶快行动起来吧!

视频中的语法

说话人最常用的结构,并附上视频中的原话:

结构视频中的用法
被动语态 be + 过去分词 — 强调发生了什么,而不是谁做的would be detected · were created
现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事We've seen

什么是跟读法?

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
