This could be the perfect sofa according to science.

從科學角度來看，這可能是最完美的沙發。

Mathematicians have spent over 50 years trying to find the magic formula for the sofa with the largest sitting area

that can be moved along an L -shaped corridor in one piece without lifting it.

At first it sounds like an easily solvable puzzle, but in reality it's quite complicated.

Square or semicircular sofas can get through the corridor, but they have barely any space to sit.

A big rectangular couch has a large sitting area, but it may not fit.

and can be moved around a right -angle corner.

If you sand off some parts and stretch others, you get an even bigger couch that still fits through the corridor.

But is this the very best option?

Well, the sofa problem is one of the unsolved problems of mathematics, and the exact value of the maximum sitting area is unknown.

New computer simulations do suggest this sofa model is very close to having the biggest possible area, but is it the most comfortable?

FOR YOU

這個影片適合誰？

無論是準備雅思口語練習的考生，還是想提升日常口語表達的學習者，這個影片都很合適。它的內容有趣且邏輯清晰，語速適中，非常適合用來做shadow speech（影子跟讀）練習。通過模仿影片中的發音和語調，你能同時鍛鍊聽力理解和口語流暢度，輕鬆掌握實用的英語表達。

值得借鑑的詞彙和習語

magic formula：神奇公式。影片中用來形容數學家尋找的最佳沙發設計方案。
sanding off：打磨掉。指通過修改沙發形狀來使其更符合要求。
unsolved problems：未解之謎。這裡指數學界尚未解決的沙發問題。

這些詞彙既專業又生動，能讓你的口語表達更豐富，在雅思口語練習中輕鬆脫穎而出。

如何練好發音？

影片中 speaker 的發音清晰，重音和語調變化自然。練習時，你可以採用英語影子跟讀的方法：先播放一句，暫停後立即重複，注意模仿每個單詞的發音和句子的節奏。重點關注“corridor”“semicircular”等長單詞的重音位置，以及“but in reality it's quite complicated”這樣的句子中語調的下降。堅持使用shadowing site進行練習，你的發音會越來越地道。

記住，影子跟讀貴在堅持。每天花10分鐘模仿這個影片，你會發現自己的口語流暢度和自信心都在提升。趕快行動起來吧！

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	can be moved
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事	have spent

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
