1
What happens when you take magic mushrooms?
2
As soon as you swallow them, your stomach acid and an enzyme called alkaline phosphatase transforms the psilocybin in the mushroom into psilocin.
3
After it slips into your bloodstream and reaches your brain, psilocin binds to and activates your serotonin receptors.
4
Regions that normally keep to themselves start talking to each other
5
and your brain's usual filter on what reaches your awareness gets much looser.
6
The result is different every time, and effects can vary.
7
Typically, patterns crawl across the walls, time stretches, unrelated thoughts snap together, and everything suddenly means something.
8
That's psilocin scrambling the brain networks that construct your familiar reality, including your sense of self.
9
But rewiring your reality for even a few hours can be dangerous.
10
It can lead to fatal accidents, and for already vulnerable individuals, high doses can trigger prolonged psychosis.
11
In medical settings with controlled doses, psilocybin is being trialed to help those suffering from depression or PTSD.
12
But outside of these conditions, mushrooms are not without risks, and not every trip is magical.

如何用这段视频练习
- 先完整听一遍视频，不要开口，记下不认识的单词。
- 先用 0.75 倍速逐句跟读，熟练之后再回到正常速度。
- 录下自己的声音并与原声对比，特别注意 dose, loose, acid 这类单词。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
