1
Your bones produce real electricity.
你的骨骼會產生真正的電流。
2
Collagen molecules, your bones' protein building blocks, contain charged groups of atoms.

3
As you walk, your bones compress and the molecules slip past each other, creating an imbalance of charges like a tiny battery.
當你行走時，骨骼會受壓，分子之間相互滑移，產生電荷不平衡，就像一個微型電池一樣。
4

幸運的是，這種電荷不會電到你。
6

但當骨骼受到壓力時，細胞就會收到訊號，召喚“施工隊”，在需要的地方生成新的軟骨組織。
11
Some scientists think collagen's piezoelectric charge is what attracts the minerals that harden the bone.
一些科學家認為，膠原蛋白的壓電電荷正是吸引礦物質使骨骼變硬的原因。
12
The precise mechanisms are still debated, but it's why exercise is good for more than just building muscle.
具體的作用機制目前仍存在爭議，但這也解釋了為什麼運動的好處遠不止增肌。
13
So even in your 60s, weightlifting can stop your bones from thinning and bulk up your spine.

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are still debated

需要注意的發音

說話人用了 3 次縮略和弱讀形式，例如 can't, don't, you'd。請按聽到的簡短形式來說。

  • 長單詞——注意重音位置: electricity /ɪˌlɛkˈtɹɪsɪti/, electrical /ɪˈlɛktɹɪkəl/, mechanism /ˈmɛk.ə.nɪ.zəm/, piezoelectricity /pʌɪˌiːzəʊ.ɪlɛkˈtrɪsɪti/

中文母語者容易讀錯的音：

  • 詞尾子音 — 要讀清楚，後面不要加母音: scientist /ˈsaɪəntəst/, shock /ʃɔk/, slip /ˈslɪp/, fluid /ˈflu.ɪd/, generate /ˈd͡ʒɛn.ə.ɹeɪt/
  • /r/ 和 /l/ 的區別: electricity /ɪˌlɛkˈtɹɪsɪti/, electrical /ɪˈlɛktɹɪkəl/, mineral /ˈmɪn.ə.ɹəl/, rebuild /ɹiːˈbɪld/, builder /ˈbɪl.dəɹ/
  • /æ/ — 嘴張大，不要讀成 /e/: attract /əˈtɹækt/, atom /ˈætəm/

如何用這段影片練習

  1. 先完整聽一遍影片，不要開口，記下不認識的單詞。
  2. 先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
  3. 錄下自己的聲音並與原聲對比，特別注意 bone, scientist, molecule 這類單詞。

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。
