Around us, everything is made of normal matter consisting of normal protons, electrons and neutrons.
3
But actually, these small building blocks all have antimatter siblings, antiprotons, positrons and antineutrons.
4
Natural sources of antimatter include supernovae and lightning strikes.
5
You should be able to rule those out occurring in your kitchen.
6
If not, please get help.
7
So, how on earth could you then have antimatter in your kitchen?

0.04 milligrams of which are radioactive potassium 40
12
and every 75 minutes one of these radioisotopes decays by emitting
13
a positron The evil twin of an electron the good news
14
antimatter is very expensive at a whopping 25 billion dollars per gram
15
if we take every banana on the planet They produce around
16
11 cents of antimatter per year what's worse after a tenth of a nanosecond each of these positrons high-fives its electron twin, and both simply disappear.

關於本課
在本課中，您將通過觀看YouTube影片《你的廚房裡有東西釋放反物質》來提高英語發音和聽力理解。影片內容討論了反物質的概念，尤其是日常生活中我們可能會遇到的例子，如香蕉中含有少量的放射性鉀。通過學習這些有趣的科學知識，您將鍛鍊您的英語口語能力，同時掌握相關的科學術語和短語，有助於您的雅思口語練習。
關鍵詞彙與短語
- 反物質 (antimatter)
- 放射性 (radioactive)
- 鉀 (potassium)
- 正子 (positron)
- 超新星 (supernova)
- 閃電 (lightning)
- 核素 (radioisotope)
- 消失 (disappear)
練習技巧
在觀看影片時，您可以嘗試使用shadow speech的技巧。這種方法可以幫助您提高英語發音。影片講解的速度適中，適合跟讀練習。為了最大程度上提高效果，建議您採取以下步驟：
- 在觀看的時候，充分注意影片中的語調和重音，這會有助於您理解如何自然地使用這些科學術語。
- 逐一暫停影片，重複說出講解者的每一句話，特別是與反物質相關的內容，確保您的發音和語調儘可能接近原聲。
- 注意正子的發音與其定義，增強您對新詞彙的記憶，同時在實際的雅思口語練習中更自信地使用這些詞語。
- 每次跟讀後，可以錄下自己的聲音，回放並與影片進行對比，這樣能夠發現自己的發音和韻律上的不足之處。
- 嘗試在日常對話中使用新學到的詞彙和短語，如“你的廚房裡有反物質嗎？”這將有助於您在自然環境中靈活運用英語。
通過持續的練習，您會發現通過看YouTube學英語，不僅可以擴充套件詞彙量，更能有效地提高您的發音和聽力水平，從而實現更好的學習成果。
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 | is made |
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。
