There's huge interest in microplastics and in fact the Mindaroo Foundation,
2
Andrew Forrest, I think he did a PhD in microplastics,
3
he's so interested in it and they funded a lot of research.
4
So they funded this research in Western Australia.
5
The first thing to say about microplastics is it's all on suspicion at the moment.
6
Even though I personally have changed my lifestyle for microplastics,
7
there's no evidence behind it.
8
And what they're trying to find out is whether
9
or not they can actually show whether there's a risk or benefit from removing microplastics.
10
So this was an enormous effort.
11
They took 200 people and 60 of them got intensive interventions to try
12
and reduce their intake of plastics from the cosmetics that they used to the food that they ate.
13
They did a deal with 150 farmers from paddock to plate
14
that the food that they produced did not to touch plastics along the way.
15
Also removing contact with plastics at home and so on.
16
To see what the effect was,
17
measuring what you were putting out in your urine in terms of the breakdown products of plastics.
18
And what they showed was that within a week,
19
most of the breakdown products reduced dramatically,
20
except one which they think could be quite a toxic metabolite,
21
of a kind called phthalate.
22
And they didn't know whether or not,
23
so good news, most microplastics went down except this one that was worrying.
24
And what they don't know here is whether or not this is in the food supply no matter what you do,
25
or because they did notice that the more fat you had on your body,
26
the less you excreted in terms of microplastics
27
and the idea here may be that you absorb these into your fat tissue
28
and therefore you don't excrete it and it may be
29
that this particular phthalate was stored in your fat
30
and therefore kept on being excreted
31
and maybe it washes out over time the next step in the study
32
so that's a fairly significant effort to get it down to
33
that low the next step in the study is to find out whether
34
or not your risk of certain diseases like diabetes and so on goes up or down depending on your exposure to microplastics.

为什么要通过这个视频练习口语？
在当今社会，微塑料的危害逐渐引起人们的关注。通过收看这段视频，你不仅可以增强自己的听力能力，还能提高英语发音。视频中探讨微塑料对健康的影响，语言丰富且专业，适合用于英语影子跟读练习。在反复模仿发音过程中，你将改善发音技巧，增强沟通自信，使你的雅思口语练习更具实用性。
语法与表达在语境中的应用
- 被动语态: 视频中多次使用了被动语态来强调研究的过程，如“微塑料被怀疑对健康的影响”。这一语法结构能够使句子更加正式，当描述研究成果或报道事实时尤为有效。
- 条件句: 句子中涉及条件的表达，例如“如果不去接触塑料，能否降低这些微塑料的摄入”。掌握这种结构将提高你在口语交流中的生动性，特别是在讨论可能的结果时。
- 名词化: 使用名词化结构来表达复杂概念，如“减少塑料摄入的干预措施”。这种表达方式适用于学术和正式场合，能帮助你在雅思口语中更好地表达观点。
常见发音陷阱
在视频中，有一些单词和短语的发音可能会让学习者感到困惑。这些发音挑战可以是以下几个方面：
- microplastics：这个词的正确发音是/mɪkroʊˈplæstɪks/，注意“micro”和“plastics”的音节分隔。
- phthalate：这个化学名词的发音较为复杂，一般读作/ˈθæleɪt/。在发音时要特别注意元音的处理。
- intervention：正确发音为/ˌɪntərˈvɛnʃən/，注意“ven”的部分，避免将其与其他发音混淆。
通过提高英语发音和不断练习，掌握这些高频词语和表达方式，将不仅能提升你在实际交流中的流利度，还能为你的雅思口语练习打下坚实的基础。
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。
