1
When an object or person falls from a great height, they are pulled towards the surface of the Earth by the force of gravity.
2
As the object or person falls, they accelerate meaning they move faster and faster towards the ground.
3
However, the air resistance or drag force pushes against them, slowing them down.
4
At some point, the drag force becomes equal to the force of gravity, and the object or person stops accelerating.
5
This is called terminal velocity, which can be different for different objects depending on their shape, size, and mass.
6
Terminal velocity for a human falling through the air is around 120 miles per hour, or about 193 kilometers per hour,
7
which is far too fast to safely reach the ground.
8
This is where a parachute comes in.
9
A parachute increases air resistance due to its shape and size, creating a larger surface area for the air to push against.
10
This slows down the person or object's descent, allowing them to land safely on the ground.
11
you .
12
It's Okay, let's go through it one more time.
13
you When a skydiver leaps from a plane, they initially accelerate due to the force of gravity.
14
Thank you.
15
As they fall, air resistance gradually increases until it balances with the force of gravity, and the skydiver reaches terminal velocity.
16
At this point, the Skydiver deploys their parachute, which increases air resistance and slows their descent.
17
allowing them to land safely on the ground.
18
you Try designing and making your own parachute to slow the fall of small objects.
19
Use a stopwatch to time the objects fall.
20
you you Thanks for watching.

背景與語境

在這個影片中,講者討論了物體在自由落體時的終極速度和空氣阻力。當人或物體從高處下落時,重力將其向地面拉動。在下落過程中,物體的速度不斷加快,但空氣阻力作用於物體,減緩其速度。影片不僅介紹了這些基本概念,還詳細解釋了傘的作用,如何通過增加空氣阻力來安全著陸。這些生動的講解不僅吸引觀眾的注意,也促進了他們對物理知識的理解,非常適合英語學習者進行跟讀練習。

日常溝通的五個常用短語

  • 重力的力量 - The force of gravity
  • 空氣阻力 - Air resistance
  • 終極速度 - Terminal velocity
  • 降低速度 - Slow down
  • 安全著陸 - Land safely

逐步影子跟讀指南

影子跟讀是一種有效的學習英語發音的方法,通過模仿講話者的聲音和語調來提高你的口語能力。以下是針對這個影片的逐步影子跟讀指南,幫助你在練習時獲得最佳效果:

  1. 觀看影片並理解內容:首先,觀看整個影片,理解講者所傳達的概念和資訊。這能幫助你在跟讀時更好地掌握內容背景。
  2. 暫停並重復:在影片的每個重要句子後暫停,模仿講者的發音和語調。這有助於提高你的英語發音。
  3. 慢慢加速:一開始可以放慢速度跟讀,等你熟悉內容後,試著逐漸加快語速,以接近講者的速度。
  4. 重點練習關鍵詞:關注影片中出現的關鍵短語,比如“終極速度”和“安全著陸”,在你的練習中反覆使用這些詞彙。
  5. 利用影子跟讀網站:可以使用一些專門的影子跟讀網站進行練習,記錄自己的發音並與原音進行對比,幫助自己不斷改進。

通過以上步驟,你可以有效地練習並提高你的英語口語能力,成為更自信的說話者。記得利用“shadowspeaks”或“英語影子跟讀”的方法,加油吧!

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。
