1
Biopharmaceuticals are produced in living cell cultures or in bacterial microorganisms.
生物製藥是通過活細胞培養或細菌微生物生產的。
2
The cells are modified in such a way that they generate the active substance of a biological medicine.
3
Once the cells are reprogrammed and multiplied to a target density, they're cryogenically frozen and stored in vessels in a cell bank.
4
Once a sample of cells is taken out from the cell bank, the cells must first be multiplied prior to use in a large fermentation vessel known as a bioreactor.
5
Several rounds of expansion follow using an enriched nutrient solution specially designed to promote growth, which gradually increases the production volume.
6
This provides the cells with optimal growth conditions and generates enough cells for the subsequent cultivation in the bioreactor.
7
Parameters such as temperature, oxygen level, pH, and cellular debris must be controlled and adapted as the cells grow.
8
Next, in the upstream process, the active substance is produced in a production bioreactor, the largest of which can hold a volume of up to 18,000 liters.
9
The active substance is produced by further modification of the nutrient media to prompt the cells into generating the desired active pharmaceutical ingredient, the API.
10
In the next process step, the downstream process, the API is separated or harvested from the cells and then purified.
11
The purification process takes place in large chromatography columns which contains special resins designed to separate the API from additives and byproducts.
12
On average a large-scale production process of a typical antibody can generate about 20 to 50 kilograms of active substance from one upstream manufacturing batch.
13
In the final step the drug products are filled into vials in a highly sterile environment and then either stored as a frozen liquid or lyophilized as freeze-dried powder.
14
Many biological medicines are also filled as liquids into syringes and stored under controlled refrigerated conditions.

為什麼要通過這個影片練習口語？
在學習英語的過程中，通過看YouTube學英語是一種有效的方法，尤其是當我們練習英語影子跟讀時。這個影片介紹了生物製藥的生產過程，內容專業且富有挑戰性，非常適合希望提升英語口語練習的學習者。通過跟讀講解，學習者不僅可以強化聽力，還能模仿發音和語調，這將大幅提升他們的口語表達能力。
語法與表達在語境中的應用
- 被動語態：例如，“生物醫藥是在活細胞培養或細菌微生物中生產的。”被動語態使語句更加正式且符合科學表述，學習者可以在描述過程時借用此結構。
- 動詞不定式：影片中提到“為了促進細胞生長”，通過學習這個結構，學習者可以更靈活地表達目的，擴大句子表達的豐富性。
- 短語動詞：影片中的“take out from the cell bank”展示了短語動詞在實驗室操作中的使用，增強了交際的自然流暢性，學生應多加練習。
常見的發音難點
在影片中，有幾個詞語的發音可能讓學習者感到困難。例如，“cryogenically”這一詞比較長且音節複雜，易於產生髮音錯誤。此外，像“bioreactor”和“chromatography”這些專業術語在快速說話中可能會讓人迷失，學習者需要進行多次英語影子跟讀以提高發音的準確性。
通過練習這些難點詞彙和語法結構，學習者能夠提高提高英語發音的能力，進而增強自己在專業語境中的溝通技能。
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 | are produced · are modified · are reprogrammed |
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。
