Prática de Shadowing: Cambridge 16 IELTS Reading Test 4 Passage 3 - Aprenda a falar inglês com vídeo
Criando lição...
1
Attitudes towards artificial intelligence.
2
A artificial intelligence, AI, can already predict the future.
3
Police forces are using it to map when and where crime is likely to occur.
4
Doctors can use it to predict when a patient is most likely to have a heart attack or stroke.
5
Researchers are even trying to give AI imagination so it can plan for unexpected consequences.
6
Many decisions in our lives require a good forecast, and AI is almost always better at forecasting than we are.
7
Yet for all these technological advances, we still seem to deeply lack confidence in AI predictions.
8
Recent cases show that people don't like relying on AI and prefer to trust human experts, even if these experts are wrong.
9
If we want AI to really benefit people, we need to find a way to get people to trust it.
10
To do that, we need to understand why people are so reluctant to trust AI in the first place.
11
They take the case of Watson for Oncology, one of technology giant IBM's supercomputer programs.
12
Their attempt to promote this program to cancer doctors was a PR disaster.
13
The AI promised to deliver top-quality recommendations on the treatment of 12 cancers that accounted for 80% of the world's cases.
14
But when doctors first interacted with Watson, they found themselves in a rather difficult situation.
15
On the one hand, if Watson provided guidance about a treatment that coincided with their own opinions, physicians did not see much point in Watson's recommendations.
16
The supercomputer was simply telling them what they already knew, and these recommendations did not change the actual treatment.
17
On the other hand, if Watson generated a recommendation that contradicted the expert's opinion, doctors would typically conclude that Watson wasn't competent.
18
And the machine wouldn't be able to explain why its treatment was plausible
19
because its machine learning algorithms were simply too complex to be fully understood by humans.
20
Consequently, this has caused even more suspicion and disbelief,
21
leading many doctors to ignore the seemingly outlandish AI recommendations and stick to their own expertise.
22
See this as just one example of people's lack of confidence in AI
23
and their reluctance to accept what Al has to offer.
24
Trust in other people is often based on our understanding of how others think and having experience of their reliability.
25
This helps create a psychological feeling of safety.
26
Al, on the other hand, is still fairly new and unfamiliar to most people.
27
Even if it can be technically explained, and that's not always the case, AI's decision-making process is usually too difficult for most people to comprehend.
28
And interacting with something we don't understand can cause anxiety and give us a sense that we're losing control.
29
Many people are also simply not familiar with many instances of AI actually working because it often happens in the background.
30
Instead, they are acutely aware of instances where AI goes wrong.
31
Embarrassing AI failures receive a disproportionate amount of media attention, emphasizing the message that we cannot rely on technology.
32
Machine learning is not foolproof, in part because the humans who design it aren't.
33
Deep feelings about AI run deep.
34
In a recent experiment, people from a range of backgrounds were given various sci-fi films about AI to watch
35
and then asked questions about automation in everyday life.
36
It was found that, regardless of whether the film they watched depicted Al in a positive or negative light,
37
simply watching a cinematic vision of our technological future polarize the participants' attitudes.
38
Optimists became more extreme in their enthusiasm for AI and skeptics became even more guarded.
39
This suggests people use relevant evidence about AI in a biased manner to support their existing attitudes,
40
a deep-rooted human tendency known as confirmation bias.
41
As L is represented more and more in media and entertainment, it could lead to a society split between those who benefit from AI and those who reject it.
42
More pertinently, refusing to accept the advantages offered by AI could place a large group of people at a serious disadvantage.
43
Unfortunately, we already have some ideas about how to improve trust in AI.
44
Simply having previous experience with AI can significantly improve people's opinions about the technology, as was found in the study mentioned above.
45
Evidence also suggests the more you use other technologies such as the internet, the more you trust them.
46
Another solution may be to reveal more about the algorithms which our users and the purposes they serve.
47
Several high-profile social media companies and online marketplaces already released transparency reports about government requests and surveillance disclosures.
48
A similar practice for AI could help people have a better understanding of the way algorithmic decisions are made.
49
If research suggests that allowing people some control over AI decision-making could also improve trust
50
and enable AI to learn from human experience.
51
For example, one study showed that when people were allowed the freedom to slightly modify an algorithm, they felt more satisfied with its decisions,
52
more likely to believe it was superior and more likely to use it in the future.
53
We don't need to understand the intricate inner workings of AI systems, but if people are given a degree of responsibility for how they are implemented,
54
they will be more willing to accept GAL into their lives.

Objetivos de fala para este vídeo
Este vídeo ajuda a aprimorar a fluência na discussão de temas técnicos e sociais, como a inteligência artificial, ao mesmo tempo que desenvolve a capacidade de articular ideias complexas de forma clara. Ideal para quem quer praticar conversações em inglês sobre inovação, confiança na tecnologia e comportamento humano, ele também estimula o shadowing — uma técnica essencial para melhorar a pronúncia e a entonação.
Banco de frases reutilizáveis
- "predict the future" (prever o futuro)
- "rely on AI" (confiar na IA)
- "contradicted the expert's opinion" (contradisse a opinião do especialista)
- "decision-making process" (processo de tomada de decisão)
- "confirmation bias" (viés de confirmação)
- "improve trust in AI" (aumentar a confiança na IA)
Essas frases são perfeitas para integrar em práticas de conversação em inglês, seja em debates ou relatos sobre tecnologia.
Corrija seus pontos fracos
O vídeo destaca a importância de dominar a ritmada da fala em inglês, especialmente ao lidar com palavras longas e termos técnicos (como "algorithms" ou "machine learning"). Muitos aprendizes têm dificuldade em pronunciar essas palavras de forma natural, mas com o shadowing em inglês — repetindo frases em tempo real — é possível melhorar a fluência. Além disso, a prática com um shadowing site ou ferramentas como o shadowspeak ajuda a internalizar a entonação, evitando que a fala fique "robótica". Observar como os falantes nativos pausam e enfatizam certas palavras (por exemplo, "Yet for all these technological advances...") também é chave para uma comunicação mais eficaz.
Use essas dicas para transformar sua prática de conversação em inglês: comece com trechos curtos, repita até sentir confiança e compare sua fala com a do vídeo. A consistência é fundamental!
O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
