Hey, it's Esther.

My friend took this video while riding in a car.

Watch the steering wheel turn and see if you notice something strange.

There's no one driving.

This is what's sometimes called a self -driving car.

Instead of a person driving, the car is controlled by a computer system with artificial intelligence.

You've probably heard about artificial intelligence or AI.

Like maybe you've heard that AI can chat with you online.

You type a question and it answers.

Or maybe you've heard that AI can make pictures, like this AI image of a made -up animal.

Someone named Damari is curious about AI.

Let's give Damari a call now.

Hi, Esther.

Hey, Damari.

I have a question for you.

How does AI work?

That's a great question.

AI is changing so fast that we can't cover everything in one video.

I just mentioned a few things that AI can do today.

Drive cars, chat, and make pictures.

These things are really different.

You might wonder how AI does them all.

But if I told you my friend could do all these things, that wouldn't be so surprising.

People can learn to do different things, and learning is a big part of how AI works.

So let's start with some ways that you learn.

Like how this baby is learning.

They're making a mess, but watch closely.

What do you think this baby is learning?

Now would be a good time to pause the video and discuss.

Okay, ready?

Maybe you guessed that this baby is learning to feed themselves.

For any baby, it takes a lot of tries to get food in their mouth.

They learn from what works and from what doesn't.

Each time a baby tries something, their brain gathers information and starts to notice similarities or patterns.

When a baby gets older, they can use what they learned from past experiences, combined with what they're noticing now, to figure out how to eat new foods.

Now imagine if, instead of learning like this, you came up with step -by -step instructions for feeding yourself.

Like, step one, find food.

Step two, pick up food.

Step three, put food in mouth.

But wait, how do you pick it up?

A slice of pizza is not like tiny peas.

And picking up soup?

Totally different.

Just think of other foods.

You'd need specific instructions for each one.

that might sound silly for a person

but step -by -step instructions are one way

that computers work people decide what they want a computer to do

and come up with step -by -step instructions for the computer

to follow you may have heard this called programming ai works differently

people still decide what they want the computer to do

but instead of step -by -step instructions they come up with programming that helps a computer system learn to do a task.

How that works gets really complicated and varies a lot, but one way is a bit like this messy learning.

Similar to how a baby gets lots of experiences with food, an AI system is given lots of information.

So an AI system designed to make images would get information

in the form of pictures photographs drawings all kinds of pictures we're talking thousands and thousands

the system is programmed to find patterns in the information like these pictures of cats

i see a pattern of having pointy ears

and furry tails the ai system can use patterns like these to make new images of cats.

But at first, the information is just a digital jumble, and the AI doesn't know what it's looking at.

It's a bit like a baby making a mess with food.

The program has to try over and over again, making messy mistakes and finding what works better.

That's how the AI learns.

Let's give the AI system a new task.

Make a picture of a unicorn cat.

It can use patterns it learns from pictures of cats

and patterns it learns from pictures of unicorns to predict what's important to include for something that's part cat and part unicorn.

Then it decides how to make a new image.

Sometimes AI systems don't get things right.

That's why AI systems are programmed to learn from what works and what doesn't in order to improve.

Today, some AI systems are able to do complicated tasks like driving,

and some can make images of things that seem real but aren't, like this one.

Hummingbirds don't actually live inside tulips.

This is an image made by AI.

This photo was taken in the real world.

That's a real hummingbird's nest.

See how incredibly tiny it is?

This photo and this AI image both seem real.

But the AI one is not what happens in real life.

That's why it's important to look up other kinds of information to learn more and check facts.

So in summary, AI systems do different things, but the basic way that they work is similar.

Instead of following step -by -step instructions, AI systems work by learning.

You learn from experiences and use what you learn to figure out how to do new tasks

and make decisions that's your intelligence

and your intelligence is the inspiration for artificial intelligence both you

and ai systems learn from what works

and from what doesn't work in order to get better at a task ai is changing fast

and there's much more to explore along with impressive things ai

can do there are also big concerns like how much energy and water is used to run AI.

There's lots of debate about when to use AI and what kinds of tasks to use AI for.

Since you're growing up in a world with AI, you can be part of figuring out how we use it in the future.

It's good to remember that having AI do a task for you isn't the same as trying it yourself.

Your brain still needs to learn by doing things that's part of your intelligence

so stay curious that's all for this week's question thanks damari

for asking it we want to know what you're curious about it's time to cast your vote

we picked three questions that we're thinking about answering

when this video's done playing click on the one you're most

excited to see answered your vote will help us plan for future mini lessons.

There are mysteries all around us.

Stay curious and see you next week.

錄下自己的聲音並與原聲對比，特別注意 instruction, unicorn, artificial 這類單詞。

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
