1
For centuries, humans have been using substances to alter their state of mind.
2
From caffeine, cigarettes and alcohol to more extreme drugs.
3
But as the most commonly used illicit drug in North America, Where does marijuana fit in and how exactly does it affect your brain?
4
First, we need to understand how the brain functions.
5
Neurons are the cells that process information in the brain.
6
By releasing chemicals called neurotransmitters from the axon of one neuron to the dendrite of another they change the electrical charge of the receiving neuron consequently exciting or inhibiting it.
7
If excited, the signal is passed on.
8
Though it sounds simple these signals work together and the effect is quickly compouned into complex configurations within milliseconds flashing over the entire brain.
9
This is what happens every single time you think, breathe or move.
10
So what is going on inside your brain when you’re smoking marijuana?
11
Well unlike alcohol, which contains molecules nothing like those in our body, cannabis contains molecules that resemble those produced in our very own brains: cannabonoids.
12
Although naturally these cannabonoids circulate at much lower quantities compared to the large influx imposed by smoking, specifically the chemical tetrahydrocannabinol or THC resembles a natural transmitter called “anandamide”.
13
These cannabonoids are specialized neurotransmitters released by neurons having just fired.
14
Neurons temporarily become unresponsive after firing to prevent them from overracting or being too dominant.
15
This allows your brain to function in a calm and controlled manner.
16
But cannabonoids interrupt this approach in some parts of the brain.
17
Instead, they remove the refractory period of neurons that are already active and can cause your thoughts, imagination, and perception to utterly magnify itself.
18
This means, once you begin your train of thought it becomes the most significant and profound thing ever.
19
You can’t see the big picture or even recall your last epiphany because you’re caught up in the momentum of a particular idea and your neurons keep firing until a new idea takes hold and you go off on a new tangent.
20
These cannabonoids also affect the levels of dopamine and norepinephrine in your brain often leading to a sense of euphoria, relaxation, pain modulation and general enhancement of an experience, though sometimes causing anxiety.
21
Furthermore, there are cannabonoid receptors in areas controlling short-term memory, learning, coordination, movement control and higher cognitive functions.

為什麼與這個影片練習口語?
在學習英語時,口語練習是非常關鍵的一環。通過觀看和模仿《你的大腦與藥物:大麻》這段影片,你可以充分了解語言的使用背景及其情感表達。影片內容涉及大腦如何工作以及大麻對思維的影響,這為你提供了實踐口語的真實語境。在這個過程中,你可以學習到如何用口頭語言描述複雜科學概念,並提升你的英語表達能力。
此外,利用“影子跟讀”(shadow speak)法,你可以通過重複影片中的句子來磨練你的發音和流利度。而這樣深入的內容也使你在進行雅思口語練習(雅思口語練習)時能夠有更具體的內容支援,增強你在考試時的自信心及應對能力。
語法與表達在語境中的應用
在影片中,演講者使用了一些可以供學習者參考的語法結構和表達方式。以下是幾個關鍵的例子:
- “這意味著……”(This means...)- 這種表達方式用於引導聽眾理解概念的核心。
- “與……相比”(Unlike...)- 這是一個比較句式,用於強調不同之處,增強論證效果。
- “神經元在釋放……”(Neurons are released...)- 這樣的結構幫助表述因果關係,適合在科學討論中使用。
- “影響……的水平”(Affects the levels of...)- 通過說明影響的範圍,演講者為其觀點提供了支援。
你可以在“英語影子跟讀”過程中,將這些句式引入到自己的口語練習中,提升你對複雜句子的掌握。
常見發音陷阱
在影片中,有幾個詞彙及其發音可能會讓學習者感到挑戰:
- “神經遞質”(neurotransmitters) - 這個詞較長且有多個音節,練習時要特別注意每個音節的清晰度。
- “大麻”(cannabis) - 常被誤讀,學習者應該多加練習以確保正確發音。
- “欣快感”(euphoria) - 這樣的詞在流利說的時候容易出錯,特別是在快節奏的情況下。
通過“影子跟讀”法,你可以有效矯正自己的發音,從而提升口語的流利度和準確性,使你在各種場合中都能自信地表達自己。
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。
