正在创建课程...
1
This could be the perfect sofa according to science.
2
Mathematicians have spent over 50 years trying to find the magic formula for the sofa with the largest sitting area
3
that can be moved along an L -shaped corridor in one piece without lifting it.
4
At first it sounds like an easily solvable puzzle, but in reality it's quite complicated.
5
Square or semicircular sofas can get through the corridor, but they have barely any space to sit.
6
A big rectangular couch has a large sitting area, but it may not fit.
7
and can be moved around a right -angle corner.
8
If you sand off some parts and stretch others, you get an even bigger couch that still fits through the corridor.
9
But is this the very best option?
10
Well, the sofa problem is one of the unsolved problems of mathematics, and the exact value of the maximum sitting area is unknown.
11
New computer simulations do suggest this sofa model is very close to having the biggest possible area, but is it the most comfortable?

这个视频适合谁？

无论是准备雅思口语练习的考生，还是想提升日常口语表达的学习者，这个视频都很合适。它的内容有趣且逻辑清晰，语速适中，非常适合用来做shadow speech（影子跟读）练习。通过模仿视频中的发音和语调，你能同时锻炼听力理解和口语流畅度，轻松掌握实用的英语表达。

值得借鉴的词汇和习语

  • magic formula：神奇公式。视频中用来形容数学家寻找的最佳沙发设计方案。
  • sanding off：打磨掉。指通过修改沙发形状来使其更符合要求。
  • unsolved problems：未解之谜。这里指数学界尚未解决的沙发问题。

这些词汇既专业又生动，能让你的口语表达更丰富，在雅思口语练习中轻松脱颖而出。

如何练好发音？

视频中 speaker 的发音清晰，重音和语调变化自然。练习时，你可以采用英语影子跟读的方法：先播放一句，暂停后立即重复，注意模仿每个单词的发音和句子的节奏。重点关注“corridor”“semicircular”等长单词的重音位置，以及“but in reality it's quite complicated”这样的句子中语调的下降。坚持使用shadowing site进行练习，你的发音会越来越地道。

记住，影子跟读贵在坚持。每天花10分钟模仿这个视频，你会发现自己的口语流畅度和自信心都在提升。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can be moved
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have spent

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。
