2
So containment is this idea that you can focus your effort
3
and control very much on the cases their contacts
4
so you're not causing disruption to the wider population you have a case
5
that comes in you isolate them you work out who they've
6
come into contact with who's potentially these opportunities for exposure
7
and then you can follow up those people maybe quarantine them to make sure
8
that no further transmission happens so it's a very kind of focused targeted method
9
and for SARS it worked remarkably well but I think for this infection because some cases are going missed and being undetected,
10
you've really got to be capturing a large chunk of people at risk.
11
If a few slip through the net,
12
potentially you're going to get an outbreak.
13
In that respect, it would be about massive changes in our social interactions.
14
And so that would require,
15
of the opportunities that could spread the virus,
16
so these kind of close contacts,
17
everybody in the population on average would be needing to reduce
18
those interactions potentially by by two-thirds to bring it under control and so that that might be
19
through through working from home from changing you know lifestyle
20
and kind of where you go and crowded places and dinners
21
and then of course these measures things like school closures
22
and other things that they just attempt to reduce the social mixing of a population
23
it's not just whose hand you shake it's whose hand
24
that person goes on to shake
25
and i think we need to think about these second-degree steps
26
that you might think you have low risk and you're in a younger group,
27
but you're often going to be a very short step away from someone who's going to get hit very hard by this.
28
And I think we really need to be socially minded
29
and think this could be quite dramatic in terms of change of behaviour,
30
but it needs to be to reduce the impact that we're potentially facing.
31
I think it's hard to pin down exactly,
32
but I think one thing to bear in mind is
33
that there's not so much evidence that this is a kind of aerosol and it goes really far,
34
that it is reasonably short distances.
35
So, you know, I don't think it's the case
36
that you're sitting a few metres away from someone and the virus is somehow going to get across.
37
I think it's really, it's as close to interactions.
38
It's why we're seeing so many transmission events occur in things like meals and really kind of tight knit groups.
39
Because if you imagine, that's where you can get virus out and onto surfaces and onto hands and onto faces.
40
And it's really kind of situations like that we've got to think more about.
41
I think that's what people are trying to piece together.
42
First, in terms of what works.
43
It's only really in the last few weeks we've got a sense
44
that this thing can be controllable with this extent of interventions.
45
But of course, not all countries can do what China have done some of these measures incur a huge social,
46
economic, psychological burden on populations.
47
And of course, there's the time limit.
48
China have had them in for six weeks,
49
and it's tough to maintain that.
50
So we need to think of these trade-offs of actually of all the things we can ask people to do,
51
what's going to have the most impact on actually reducing the burden?

语境与背景
在最近的一场TED演讲中，演讲者讨论了COVID-19疫情的控制方法，强调通过针对性地隔离病例及其接触者，以减少病毒传播。演讲中提到了一系列社会交互的变化，强调每个人在日常生活中的行为调整对于控制传播的重要性。这些观点为我们理解疫情处理和日常交流中的发音和词汇选择提供了宝贵的知识。
日常沟通的五个重要短语
- 隔离病例 (isolate cases)
- 减少社交互动 (reduce social interactions)
- 接触者追踪 (contact tracing)
- 传播机会 (opportunities for transmission)
- 行为变化 (changes in behavior)
逐步跟读指南
在进行shadow speaking练习时，可以参考以下步骤来逐步减少难度，并提高你的英语口语练习能力：
- 听并理解：首先，仔细聆听视频，尝试理解演讲者的主要观点和情绪。可以多次反复播放，确保掌握内容大意。
- 跟读模仿：开启视频的字幕功能，尝试模仿演讲者的发音和语调。注意短语的重音和节奏，使用提高英语发音技巧。
- 分段练习：将视频拆分成多个小段落，独立跟读每个段落，这样更容易掌握每个句子的结构和用词。
- 录音对比：录下自己的跟读声音，然后与原视频做对比，这样可以清楚认识自己的发音和语调问题。
- 日常应用：尝试将视频中的短语应用到自己的日常交流中，提升雅思口语练习的自信心和流畅度。
通过以上的练习方法，可以有效提升你的英语口语能力和理解水平，为更好地应对各种交流场景做好准备。
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。
