1
When I was a kid, the disaster we worried about most was a nuclear war.
2
That's why we had a barrel like this down in our basement, filled with cans of food and water.
3
When the nuclear attack came, we were supposed to go downstairs, hunker down, and eat out of that barrel.
4
Today the greatest risk of global catastrophe doesn't look like this.
5
Instead, it looks like this.
6
If anything kills over 10 million people in the next few decades, it's most likely to be a highly infectious virus rather than a war.
7
Not missiles, but microbes.
8
Now, part of the reason for this is that we've invested a huge amount in nuclear deterrents.
9
But we've actually invested very little in a system to stop an epidemic.
10
We're not ready for the next epidemic.
11
Let's look at Ebola.
12
I'm sure all of you read about it in the newspaper, lots of tough challenges.
13
I followed it carefully through the case analysis tools we use to track polio eradication.
14
And as you look at what went on, the problem wasn't that there was a system that didn't work well enough, the problem was that we didn't have a system at all.
15
In fact, there's some pretty obvious key missing pieces.
16
We didn't have a group of epidemiologists ready to go, who would have gone, seen what the disease was, seen how far it had spread.
17
The case reports came in on paper.
18
It was very delayed before they were put online and they were extremely inaccurate.
19
We didn't have a medical team ready to go.
20
We didn't have a way of preparing people.
21
Now, Médecins Sans Frontières did a great job orchestrating volunteers.
22
But even so, we were far slower than we should have been getting the thousands of workers into these countries.
23
And a large epidemic would require us to have hundreds of thousands of workers.
24
There was no one there to look at treatment approaches.
25
No one to look at the diagnostics.
26
No one to figure out what tools should be used.
27
As an example, we could have taken the blood of survivors, processed it, and put that plasma back in people to protect them.
28
But that was never tried.
29
So there was a lot that was missing.
30
And these things are really a global failure.
31
The WHO is funded to monitor epidemics, but not to do these things I talked about.
32
Now, in the movies it's quite different.
33
There's a group of handsome epidemiologists ready to go, they move in, they save the day, but that's just pure Hollywood.
34
The failure to prepare could allow the next epidemic to be dramatically more devastating than Ebola Let's look at the progression of Ebola over this year.
35
About 10,000 people died, and nearly all were in the three West African countries.
36
There's three reasons why it didn't spread more.
37
The first is that there was a lot of heroic work by the health workers.
38
They found the people and they prevented more infections.
39
The second is the nature of the virus.
40
Ebola does not spread through the air.
41
And by the time you're contagious, most people are so sick that they're bedridden.
42
Third, it didn't get into many urban areas.
43
And that was just luck.
44
If it had gotten into a lot more urban areas, the case numbers would have been much larger.
45
So next time, we might not be so lucky.
46
You can have a virus where people feel well enough while they're infectious that they get on a plane or they go to a market.
47
The source of the virus could be a natural epidemic like Ebola, or it could be bioterrorism.
48
So there are things that would literally make things a thousand times worse.
49
In fact, let's look at a model of a virus spread through the air, like the Spanish Flu back in 1918.
50
So here's what would happen: It would spread throughout the world very, very quickly.
51
And you can see over 30 million people died from that epidemic.
52
So this is a serious problem.
53
We should be concerned.
54
But in fact, we can build a really good response system.
55
We have the benefits of all the science and technology that we talk about here.
56
We've got cell phones to get information from the public and get information out to them.
57
We have satellite maps where we can see where people are and where they're moving.
58
We have advances in biology that should dramatically change the turnaround time to look at a pathogen and be able to make drugs and vaccines that fit for that pathogen.
59
So we can have tools, but those tools need to be put into an overall global health system.
60
And we need preparedness.
61
The best lessons, I think, on how to get prepared are again, what we do for war.
62
For soldiers, we have full-time, waiting to go.
63
We have reserves that can scale us up to large numbers.
64
NATO has a mobile unit that can deploy very rapidly.
65
NATO does a lot of war games to check, are people well trained?
66
Do they understand about fuel and logistics and the same radio frequencies?
67
So they are absolutely ready to go.
68
So those are the kinds of things we need to deal with an epidemic.
69
What are the key pieces?
70
First, we need strong health systems in poor countries.
71
That's where mothers can give birth safely, kids can get all their vaccines.
72
But, also where we'll see the outbreak very early on.
73
We need a medical reserve corps: lots of people who've got the training and background who are ready to go, with the expertise.
74
And then we need to pair those medical people with the military.
75
taking advantage of the military's ability to move fast, do logistics and secure areas.
76
We need to do simulations, germ games, not war games, so that we see where the holes are.
77
The last time a germ game was done in the United States was back in 2001, and it didn't go so well.
78
So far the score is germs: 1, people: 0.
79
Finally, we need lots of advanced R&D in areas of vaccines and diagnostics.
80
There are some big breakthroughs, like the Adeno-associated virus, that could work very, very quickly.
81
Now I don't have an exact budget for what this would cost, but I'm quite sure it's very modest compared to the potential harm.
82
The World Bank estimates that if we have a worldwide flu epidemic, global wealth will go down by over three trillion dollars and we'd have millions and millions of deaths.
83
These investments offer significant benefits beyond just being ready for the epidemic.
84
The primary healthcare, the R&D, those things would reduce global health equity and make the world more just as well as more safe.
85
So I think this should absolutely be a priority.
86
There's no need to panic.
87
We don't have to hoard cans of spaghetti or go down into the basement.
88
But we need to get going, because time is not on our side.
89
In fact, if there's one positive thing that can come out of the Ebola epidemic, it's that it can serve as an early warning, a wake-up call, to get ready.
90
If we start now, we can be ready for the next epidemic.
91
Thank you. (Applause)

背景与背景信息
比尔·盖茨在TED演讲中谈到了全球面临的最大风险：未准备好的传染病疫情。与他童年时期对核战争的担忧不同，盖茨指出，未来可能导致超过一千万人死亡的，并非核导弹，而是高度传染的病毒。虽然我们在核威慑方面投入了大量资源，但针对疫情的准备却相对薄弱。他强调过去的疫情，如埃博拉病毒，暴露了我们在疫情监测、医学团队和治疗方案方面的不足。
日常交流中的五个重要短语
- “我们没有准备好” - 强调应对能力不足。
- “全球性失败” - 指出在疫情防控中的重大不足。
- “有很多英勇的工作” - 赞扬在危机中的医务工作者。
- “这是纯好莱坞” - 批评电影中的不现实情节。
- “我们可能不会再幸运” - 提示未来疫情可能更加严重的风险。
逐步影子跟读指南
为了提升您的英语口语技能，尤其在阴影跟读（shadow speaking）方面，您可以按照以下步骤进行学习：
- 选择段落：选择比尔·盖茨演讲中您感兴趣的句子或段落进行重点练习。
- 听音频：首先认真倾听视频，确保您能够理解每一个单词和句子的语调。
- 逐句跟读：暂停视频，模仿盖茨的发音与语调，运用“英语影子跟读”的技巧。尽量去捕捉他的语气与情感。
- 反复练习：反复播放片段，直至您能够流利地复述出来，并注意改善您的发音和重音。
- 录音对比：录下您自己的声音，并与视频中的音频进行对比，找出可以改进的地方。
这些步骤将有助于您提高英语发音，并在英语口语练习中取得更好的进展。通过持续的努力，您将能够更加自信地在实际对话中应用所学内容。
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。
