1
With an estimated 2 million pills being smuggled into the US every day
2
and one -third of students at universities like Stanford saying they've tried it, MDMA, or MOLLY, has become a popular drug of choice.
3
But what exactly is it and how does it affect your body?
4
Scientifically known as 3 ,4 -methylene -dioxy and methyl amphetamine,
5
MDMA is usually taken in pill form and supposed to be composed of the pure chemical. or caffeine.
6
In its pure form, MDMA affects the neurotransmitters in your brain.
7
Neurotransmitters are chemicals in your body which relay messages while also controlling things such as reflexes, emotion, and memory.
8
In particular, the neurotransmitter called serotonin controls appetite, sleep, memory, learning, and in this case, mood.
9
When something really great happens in your life, say you fall in love, there's an increase in the release of serotonin from nerve cells, which ultimately stimulates your body and makes you feel happy.
10
And it just so happens These same cells are triggered to release enormous amounts of serotonin,
11
along with other neurotransmitters like dopamine and norepinephrine, which trigger even more electrochemical firing in the brain.
12
This change creates the intense experience of happiness, feeling social, increased empathy, and the inability to sleep, which is likely why it's such a popular party drug.
13
These feelings generally last around 3 -8 hours, as your brain cells naturally work to reuptake the serotonin and have it chemically destroyed.
14
destroys more than usual.
15
This means when your brain function is back in its "normal" state, there is less serotonin available to bind to your receptors and make you feel good with normal events.
16
This can also lead to a fairly severe hangover with side effects such as negative mood, spouts of depression, irritability and feeling extra tired.
17
Despite the negative effects, MDMA is being studied as a potential therapy for post -traumatic stress disorder and anxiety.
18
PTSD patients generally have a decrease in brain communication between the amygdala and the hippocampus, but MDMA is being studied as a potential therapy for post -traumatic stress disorder and anxiety.

PTSD patients generally have a decrease in brain communication between the amygdala and the hippocampus, but MDMA is being studied as a potential therapy for post -traumatic stress disorder and anxiety.
23
PTSD patients generally have a decrease in brain communication between the amygdala
24
and the hippocamp MRI analysis has shown that MDMA actually increases the communication in these regions.
25
However, this treatment remains fairly controversial as studies on rats
26
and monkeys have shown
27
that even small amounts of MDMA can not only destroy the endings of brain cells involved in the release of serotonin, but potentially cause permanent brain damage.

关于本课

在本节课中,您将通过收听和跟读一段关于MDMA(亚甲二氧基甲基安非他命)对大脑影响的科学视频,练习您的英语听力和口语。通过影子跟读(英语影子跟读)的方式,您将提高对复杂句子结构的理解能力,以及在实际对话中使用专业词汇的能力。这将有助于您在雅思口语练习中表现得更加自信和流畅。

关键词汇与短语

  • 神经递质 (neurotransmitters) - 控制大脑信号传递的化学物质。
  • 多巴胺 (dopamine) - 一种与快乐感和奖励系统相关的神经递质。
  • 情绪 (mood) - 心理状态的表现。
  • 焦虑症 (anxiety) - 情感障碍的一种,表现为过度担忧或紧张。

  • 快感 (pleasure) - 被愉悦或快乐的感觉。

练习技巧

在进行影子跟读练习时,您可以遵循以下几点建议,以便有效提高英语韵律和发音:

  • 慢速跟读:首先,以较慢的速度播放视频,并尝试恢复视频中的句子,确保每个词的发音都准确。慢慢增强您的自信心,并影响您的英语发音。
  • 重复多次:对于困难的句子,您可以循环播放,将其分成小部分逐句进行跟读。这将帮助您掌握语调和节奏。
  • 关注语调:在模仿说话者的同时,注意他们的语调变化。这将有助于您在雅思口语练习中拥有更好的表述能力。
  • 配合肢体语言:在跟读过程中,尝试使用肢体语言来加强您的理解。这不仅可以提高您的学习兴趣,还能增强对内容的记忆。
  • 自我反馈:录制自己的跟读,并与原音进行比较。分析差异,进一步调整自己的发音,提升整体口语技能。

通过这些练习技巧,您不仅能够提高英语发音,还能在实际交流中增强自信,给他人留下深刻印象。无论是学习新的专业词汇,还是在日常对话中运用流畅的英语,这些都是您前进的垫脚石。

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。
