1
One of the functions of the small intestine is to take digested food molecules from the digestive system
2
and transfer them into the blood,
3
so that they can be transferred to the parts of the body that need them.
4
The digested food in the small intestine contains molecules such as glucose from the digestion of starch,
5
amino acids from proteins, fatty acids and glycerol from lipids,
6
as well as lots of other essential materials.
7
These must be absorbed into the bloodstream so that your body can use them.
8
The walls of the small intestine are lined with intestinal villi.
9
And FYI, it's one villus, many villi.
10
Villus is the singular, villi is plural.
11
The villi increase the surface area of the wall of the small intestine to maximize the rate of absorption of digested food.
12
Picture one flat line between points A and B,
13
and imagine that material has to transfer across it.
14
If you measure this line,
15
the length of the surface for materials to transfer,
16
you'll see it's 10cm long.
17
Now picture a line between the same points A and B,
18
but on this new line there are finger-like projections all the way along.
19
If you measure along the surface of this line,
20
you'll find it's far longer than 10 centimeters.
21
The version with the projections has a larger surface area,
22
meaning more material can be transferred in the same amount of time.
23
time.
24
Here's a simplified diagram showing a single villus.
25
Food molecules are transferred from the central space in the small intestine into the villi.
26
The epithelial cells of its lining have many micro villi on them.
27
This further increases the surface area.
28
have a good blood supply constantly flowing in and out through many blood capillaries.
29
Most materials are transferred to the blood capillaries.
30
There's also a structure inside each villus called a lacteal,
31
and the products of lipid digestion are absorbed into this part,
32
and from there they'll also eventually reach the bloodstream at a different point.

為何要通過此影片練習口語?

通過本影片進行英語影子跟讀,能有效提升您的英語口語能力。這種練習方式專注於模仿影片中講解者的語調、節奏和發音,幫助學習者在更真實的語境中理解並運用語言。與示範發音相結合,能夠促進對語調和情感表達的更深入理解,不僅提升了聽力水平,也增強了口語表達能力。通過這一過程,您將能夠在口語練習中取得顯著進步,從而在日常交流中更加自信。

語法與表達在語境中的應用

在影片中,講解者使用了一些關鍵的語法結構和表達方式,以下是其中的三到五個例子:

  • 動詞不定式: “to take digested food molecules” (將消化食物分子轉移),這裡使用了動詞不定式,強調了動作的目的。
  • 被動語態: “that they can be transferred” (可以被轉移),此處的被動結構突出動作的接受者。
  • 條件句: “if you measure this line” (如果你測量這條線),顯示了假設條件的重要性。
  • 特定名詞的複數形式: “villus is the singular, villi is plural” (單數是villus,複數是villi),此處幫助學習者理解名詞變化。

這些表達方式能夠幫助學習者在口語練習中自然運用相同結構,增進其流利度。

常見發音陷阱

在影片中,有些單詞和發音可能會成為學習者的一些挑戰:

  • villi:這個單詞的發音容易被混淆,正確的發音應注意雙音結合。
  • absorb:注意其中的母音發音,這個單詞的發音和拼寫有時會讓人困惑。
  • capillaries:這個字的發音較長,需要多加練習,以避免發音不清晰。

通過不斷的跟讀和練習,您可以有效提高自己的發音技巧和口語流利度。為更好掌握這些發音陷阱,建議在練習時結合英語口語練習和提高英語發音的資源,幫助更好地糾正和改善發音。繼續通過shadowspeak的方式強化自己的語音能力,將使您的英語口語更上一層樓。

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。
