hello friends
my name is Anne Marie,
and today is a great day to learn something new.
So let’s do that together. I’m David,
and this is Studio Classroom.
Friends, you’re just in time for a very exciting technology article.
So to begin our lesson,
let’s start with a question. Here it is:
Have you ever used a virtual reality headset?
I did, one time.
I was invited by a company to go and try out one of their products,
and it was a special—sort of like the kind of headset we’re talking about today—
an XR headset that combined AR and VR.
AR, VR, XR怎麼區別？ ChatGPT 說：
這是個非常常見又容易搞混的問題，以下是對 AR、VR、XR 的清楚區別與簡易說明：
🔹 AR（Augmented Reality 擴增實境）
✅ 關鍵詞：在現實中疊加虛擬物件
使用者看到的是真實世界，加上虛擬影像或資訊。
虛擬內容通常是透過手機、平板、或AR眼鏡「疊加」在現實畫面上。
📌 例子：
手機遊戲《Pokémon Go》（寶可夢GO）
IKEA Place App：將虛擬家具放在你家中
手機掃描展覽品時出現3D介紹動畫
🔹 VR（Virtual Reality 虛擬實境） ✅ 關鍵詞：完全沉浸在虛擬世界
使用者完全被虛擬環境包圍，看不到現實世界。
必須戴上 VR頭盔/眼罩（如Meta Quest、HTC Vive等）。
📌 例子：
VR恐龍博物館，讓你彷彿走進侏羅紀
虛擬遊戲如《Beat Saber》、《Half-Life: Alyx》
VR模擬飛行器、醫療手術訓練
🔹 MR（Mixed Reality）混合實境 概念：
結合真實世界與虛擬物件，這些虛擬物件可以與現實世界互動。你可以看到、控制並與虛擬物件「真實互動」。
常見例子：
用HoloLens看見虛擬會議參與者坐在真實椅子上
虛擬按鈕貼在牆上可用手控制
設備：
進階AR裝置（如 Microsoft HoloLens、Magic Leap）
通常需要空間定位與手部追蹤功能
🔹 XR（Extended Reality 延展實境） ✅ 關鍵詞：AR + VR + 其他混合形式的總稱
XR 不是一種具體技術，而是統稱所有結合真實與虛擬世界的技術。
包含了：
AR（擴增實境）
VR（虛擬實境）
MR（Mixed Reality 混合實境）
📌 例子：
Microsoft HoloLens 使用 MR 技術，因此屬於 XR 的一種
XR 被應用在遠距會議、軍事訓練、設計、醫療等複合場景
✅ 總結對照表：
技術 代表名稱 是否看到真實世界 是否有虛擬物件 裝置例子
AR 擴增實境 ✅ 是 ✅ 有 手機、AR眼鏡
VR 虛擬實境 ❌ 否 ✅ 有 VR頭戴裝置（如Meta Quest）
XR 延展實境（統稱） 可能有或沒有 ✅ 有 各種AR、VR、MR裝置
We’ll talk about those terms later. But it was very strange. For one, it was heavy.
And number two, I had trouble getting used to the environment.
It was kind of hard to figure out where I was.
Yeah, I’ve tried them out maybe once or twice as well,
and always in a situation where I was playing a type of video game.
And I found that they made me quite dizzy.
This was several years ago,
so I bet the technology is even better now.
But friends, the title of our article today is called A Whole New World.
Let’s get right into our first reading for the day.
A Whole New World
Check out the new tech blurring the lines between the digital and the real.
The bell rings,
and you and all your classmates get ready for history class.
Today you’ll be studying Egyptian history.
But instead of telling you to open a textbook,
the teacher gives you each a special headset.
You put on the device,
and within moments,
your classroom is filled with ancient Egyptian relics
that you can pick up and interact with.
This is the magic of mixed reality,
MR—a technology that is transforming the way people work, learn, and play.
Hi everyone, welcome to Language Lab. I’m Jack.
我們來看 relic 這個名詞。請留意它的發音是 relic。意思是遺跡或是遺物。
來看幾個例句：
Which of these relics would interest you the most—dinosaur fossils or the gold jewelry of an ancient queen?
你對哪種文物最感興趣呢？恐龍化石，還是古代王后的首飾？
或者：
Bob complained that the sign reading “No coffee allowed in the office” was a relic
from the former boss who hated the smell of coffee.
Bob 抱怨說，辦公室禁止喝咖啡的牌子是前任老闆留下來的，因為他討厭咖啡的味道。
或是：
That worn, hand-sewn blanket is not just a piece of cloth.
It’s the precious relic of the past.
那條手工縫製的破舊毯子不僅是一塊布，更是一件珍貴的歷史文物。
All right, thank you so much, Jack. Friends,
let’s get right into our lesson.
We read here:
Check out the new tech blurring the lines between the digital and the real.
Now, there’s a phrase that we need to talk about first here—
this is the idea of blurring the lines.
That’s right.
Now, if you blur the lines between two different things,
then you make the differences between those things unclear.
That’s right. Here’s an example of how you can use blurring the lines in a sentence:
Technology is blurring the lines between work life and home life.
It certainly is.
All right, going on—
we see that we are blurring the lines between the digital and the real.
This article is painting a picture for us.
The bell rings,
and you and all your classmates get ready for history class.
Today you’ll be studying Egyptian history.
But instead of telling you to open a textbook,
the teacher gives each of you a special headset.
Oh, a headset—this is a great word for you to know, friends.
This is a device worn on the head for communication or for virtual reality.
The idea is that it is something that you put on your head.
Now, headsets can be a little different.
Sometimes, you might have a headset that just covers your ears.
Sometimes the headset might just cover your eyes.
Or it might cover both.
That’s right. Maybe you go to an arcade place with lots of video games,
and you put on a special headset and prepare to play a cool racing game.
That sounds like a lot of fun.
But we read on here:
You put on the device,
and within moments,
your classroom is filled with ancient Egyptian relics.
That sounds like a lot of fun.
This is some hands-on learning.
You can pick these relics up and interact with them.
This is the magic of mixed reality.
MR—what is this, Dave?
Mixed reality is a blend of real and virtual worlds.
Actually, this is the kind of VR experience that I was talking about
when you asked me that question.
It was a mixed reality environment.
It was cool, but it was kind of hard to get used to.
Okay, so let me ask a question—
so I understand the difference.
When I used a virtual reality headset,
it was for a video game.
I think we were chasing down zombies.
That wouldn’t be mixed reality, right?
Well, it depends on how the game works.
A virtual reality world is one where everything is virtual—
there’s nothing that you’re interacting with as if it were a real object.
Whereas a mixed reality world is a system
that uses some real-world objects
or things that might be in the room,
and allows you to interact with them as if they were real.
Ah, I see.
What I used was definitely just virtual reality, then.
So this is a little bit different.
This is a technology that is transforming the way people work, learn, and play.
We have another great word to take a look at, friends—
the word transforming.
Right—if something transforms, or is transforming,
it means that it’s changing completely.
Here’s an example of how you could use transforming in a sentence:
AI is transforming the way we work.
It is changing something completely.
We do it in a completely different way.
Well, friends, we definitely have more to learn about mixed reality.
So let’s get on with our next reading right now.
A Whole New World
By combining physical and virtual elements,
MR enables users to interact with digital objects
as if they were part of the real world.
While Virtual Reality (VR) transports you to a digital world,
and Augmented Reality (AR) adds digital objects to the real world,
MR blends the two to create a fully interactive environment.
接下來看形容詞：
interactive 意思是「互動的」。
比如：
I want to switch to a different history class where the teacher has a more interactive style.
我想換到另一堂歷史課，那堂課的老師有更多的互動性。
interactive 的名詞是 interaction，也是指「互動」。
例如：
After a pleasant interaction with her neighbor about flowers, Susan realized he was not as unfriendly as she had thought.
在跟鄰居就花卉進行了愉快的交流後，Susan 意識到他並不像她想的那麼不友善。
interactive 的動詞是 interact，意思是「互動」。
譬如：
If I had more opportunity to interact with Americans, I think my English would really improve.
如果我有更多的機會與美國人交流，我想我的英語會有很大的提升。
All right, friends,
let’s continue on with the next part of our lesson.
We see:
By combining physical and virtual elements,
MR enables users to interact with digital objects
as if they were a part of the real world.
Okay, we have a couple of things we need to take a look at here.
First, I want to say that
when we’re talking about something being physical,
it means it’s something that we can touch—
it’s something that exists in the real world.
And as we said earlier,
this word virtual means that it is happening on a computer or online.
That’s right. Now, we also see this word enables,
so we see that MR enables us to do something.
If something enables you to do something,
it means that it makes that something possible.
For example:
The new app enables students to learn faster.
It helps them do something—
it makes it possible.
But we also see something else here, friends,
and this is the phrase as if.
When you see this,
it means that something is done in a way that appears to be true.
That’s right. For example:
The man spoke as if he knew everything,
but he really didn’t.
Exactly. So when you see as if,
it means that he’s trying to make you believe something,
or he’s pretending something is true—
but it’s really not.
That’s right.
Now we’re going to get into some slightly more technical details
of what makes this special in the next sentence.
All right, now we see that:
While virtual reality (or VR) transports you to a digital world—
like your zombie game, right?—
and augmented reality (which is AR) adds digital objects to the real world—
kind of like Pokémon GO, a very popular game right now—
MR blends the two to create a fully interactive environment.
Okay, so to define augmented reality, friends—
this is technology that adds digital elements to the real world,
like Pokémon GO.
That’s right. So for example, in Pokémon GO,
you’re using your mobile device—your smartphone—
and it’s connecting actually to something like Google Maps
or something that can tell where you are.
And then it’s taking a digital reality
and kind of placing it over that map,
sort of almost like a mask.
So instead of looking down at your device and seeing,
“Oh, I’m on Maple Street,”
instead you see that, yes,
I’m on Maple Street—
and there’s a Pikachu right there who’s running towards me!
I have to throw my Pokéball to catch it!
(I don’t think that’s how you really play Pokémon GO, but…)
Something like that, yeah. Exactly.
And this is something that’s used a lot now in modern gaming.
Augmented reality has really changed the way
we interact with computers, and technology, and gaming as well.
Well, you already learned about this word here:
interactive, friends.
An interactive environment means that you can touch, feel, or see things
that are in real life and interact with them.
Now we’re going to go on
to learn more about the technology behind MR.
But first, let’s go through today’s Info Cloud.
Hello friends, welcome to Info Cloud.
Hey Rex, I heard you were trying out some new hiking trails this weekend.
How’d that go?
Hey Garrett, it was amazing!
Some of those trails were rough, though.
They definitely pushed the boundaries
of what the word trail means.
Ah, that’s an interesting expression too.
When something is pushing the boundaries,
it is going beyond the usual limits
of what’s expected, accepted, or even possible.
That’s right.
It’s often used to describe positive things like innovation,
creativity, or taking risks to achieve something new.
But it also describes situations in which people step outside
their comfort zones, break rules, or upset other people.
So you’ll hear things like:
“The scientist is pushing the boundaries of medicine.”
But you’ll also hear things like:
“My teenage son is really pushing the boundaries
and getting in a lot of trouble.”
The phrase’s origins aren’t clear,
but its meaning and use are similar to the phrases
“push the limits” (which is positive)
and “push one’s luck” (which tends to be more negative).
There you have it, friends.
You probably shouldn’t push all boundaries,
but I hope you are pushing the boundaries of your English abilities
as you learn with us on Info Cloud.
pushing the boundaries (pushing the limits) 突破界限 很多人會跳脫舒適圈，努力地突破自我。
今天要跟大家分享的用語是 pushing the boundaries，也就是突破界限或是超越限制，
挑戰一些超乎預期的範圍。
例如：
The scientist is really pushing the boundaries of medicine.
那位科學家真的是在挑戰醫學領域的界限。
或許他正在做一些顛覆傳統的研究工作。
另一個類似的用語是 pushing the limits，突破限制。
還有一個比較負面的用法：
pushing one’s luck，挑戰自己的運氣，去做一些危險的事情。
這就是今天的 Info Cloud，我們下次雲端見！
A Whole New World Using cameras, sensors, and special software,
MR blends real-world scenes with virtual environments.
The system scans the user’s environment
before building the virtual environment onto it,
and then uses sensors to detect movement,
lighting, and other physical details.
The principal difference between AR and MR
is the ability to interact with digital objects
within that environment,
as though they were physically present.
In MR, digital objects respond to your movements,
allowing you to pick them up,
move them,
or see them from different angles—like real objects.
今天的 Usage Tip 要來看 before（在……之前）或 after（在……之後）。
可以用來表達主詞執行動作一（verb one）和動作二（verb two）兩個動作的先後順序。
使用 before 表示先動作一，再動作二；
使用 after 則表示先動作二，再動作一。
before 和 after 可以視為介系詞，所以動詞要以 動名詞（V-ing）形式放在後面當受詞，
而且這個動詞必須是主詞執行的動作，否則將造成文法上的錯誤。
來看例句：
They decided what to order after browsing several of the restaurant’s online reviews.
他們瀏覽了幾則這家餐廳的網路評價後，才決定點什麼菜。
Okay friends,
in this next section we’re going to learn a little bit more
about how mixed reality works.
We see here:
Using cameras, sensors, and special software,
MR blends real-world scenes with virtual environments.
I think in order to understand what this means,
we need to talk about what that word sensor means.
Yes.
Sensors are a very important part of, actually,
a lot of things in the world we live in—everything from
the automatic soap machines that you see in bathrooms
to automatic doors that open when you walk up to them.
Sensors are devices that detect changes in the environment.
For example, some cars have sensors in them
that tell you when you’re about to hit something
or help you park your car.
The sensor lets you know if there’s an obstacle in the way.
That’s right.
Although those car parking programs are almost useless in Taipei,
I’ve realized. Don’t rely on those. Don’t rely on those!
Anyway, these devices use cameras, sensors, and special software.
Right, so they’re using these different devices
in order to sort of create a digital version
of the real place that you’re in.
Now in the next sentence, we see that:
The system scans the user’s environment
before building the virtual environment onto it,
and then uses sensors to detect movement.
There’s a lot going on here.
First word is the word scans.
If you scan something, it means that you look at it carefully
and read the data.
That’s right. Here’s an example of how you can use the word scan in a sentence:
The doctor scanned the X-ray for issues.
Now, as you can see in this example,
a person could be the one doing the scanning,
or those sensors could also be the one doing the scanning.
If any of you like to use computers,
you probably have used some kind of program
to scan your computer and check for viruses.
So the word scan is something that comes up a lot in technology.
In the next part of the sentence,
we see that the sensors are detecting movement and lighting,
as well as other physical details.
So first, we get a scan of the whole room,
and then sensors allow our real movements
to interact with that digital environment.
Okay friends,
in this next sentence we are going to learn about the difference
between AR and MR.
We read:
The principal difference between AR and MR
is the ability to interact with digital objects
within that environment,
as though they were physically present.
Now we see as though here, friends,
and we need to talk about what that means.
This means that it is done in a way that seems true.
This kind of reminds me of that phrase as if
we learned earlier, right?
You can use it in almost a similar way.
For example:
The man acted as though nothing happened,
but actually, he was sad about something.
So as if and as though are very similar phrases, friends.
Now we read on here:
In MR, digital objects respond to your movements.
All right—respond to—let’s talk about that.
If you respond to something, it means that you reply
or react to something someone said or something that happened.
Sometimes we spend time at work responding to emails.
These are emails that we have already gotten,
and we need to take the time to write a response.
Not always a fun thing to do, but a very important part of the job.
Anyway, in MR, digital objects respond to your movements
and allow you to pick them up, move them,
or see them from different angles—like real objects.
So I can see how this type of technology
would work really well in a classroom.
It would make students be able to interact with the environment
more, rather than if they were just reading from a textbook.
That’s right. Imagine, just like in our example,
they’re able to walk up to one of those Egyptian coffins,
open it up,
and see a mummy there.
Very cool. Very cool.
All right friends, we have a little bit more to learn in just a moment.
We’ll be back after today’s Fun Fact.
Hello, fact friends! I am Detective Ernest Finder,
and I have a Fun Fact for you today.
Did you know Studio Classroom has virtual reality products?
Haha! It’s true, it’s true.
You can learn real English in a virtual world! Haha!
And that is today’s Fun Fact.
All right friends, we’ve talked a lot about VR, AR, and MR.
And for me, Dave, when I think about these new technologies,
I often think of some of the security risks that come with them.
What do you think?
Do you think that MR technology is worth the cost and the privacy risks?
I think that the most useful place for MR
is in very specific situations—like medical environments
or maybe even some educational environments as well.
But as a regular product that I would go out and buy? No.
I’m a little bit too concerned with the security risks as well.
What do you think, friends?
This is a great thing for you to talk about in English.
Well, that’s all the time we have for today.
My name is Anne Marie.
And I’m David.
And we’ll see you next time
right here on Studio Classroom.
Bye!

Hello, friends.
My name is Anne Marie,
and today is a great day to learn something new.
So let’s do that together. I’m David,
and this is Studio Classroom.
You’re just in time for Day Two of our article called:
A Whole New World
We are not talking about a Disney movie here.
What are we talking about?
We are talking about mixed reality,
which is a blend of virtual reality and augmented reality.
That’s right. Yesterday,
we learned that one of the main
differences between virtual reality
and mixed reality is: with mixed reality,
you can actually interact with the environment.
That’s right—it uses a combination of cameras,
sensors, and special software to sort of
paint the digital world on top of the physical world
and enable you to interact with it.
Friends, there’s a lot more to learn when it comes to mixed reality,
so let’s get started with our first reading right now.
A Whole New World
MR is reshaping industries
by integrating digital and physical elements
for groundbreaking applications.
In healthcare,
MR provides realistic simulations,
enabling medical professionals
to practice virtual operations
as if they were working on real patients.
In gaming and entertainment,
MR transports users to worlds where they can do anything—
from raising virtual pets
to defending their homes from zombie invasions.
And in other industries,
MR enables engineers to experiment with virtual prototypes
within blended environments,
reducing costs and improving efficiency.
Hi everyone, welcome to Language Lab. I’m Jack.
首先來看 simulation 這個名詞，意思是「模擬」。
來看例句：
The dentist
offered to show me a computer simulation of the technique he would use to remove my tooth, but I said no.
牙醫提議給我看他會用來拔牙的電腦模擬技術，但我拒絕了。
Simulation 的動詞是 simulate，意思也是「模擬」。例如：
The alarm that I use on my phone simulates the pleasant sound of falling rain.
我手機上的鬧鐘鈴聲模擬了悅耳的雨聲。
或是：
Harriet was extremely bored during the museum tour, but she simulated interest so as not to offend the guide.
Harriet 在參觀博物館的過程中覺得很無聊，但為了不得罪導覽員，她還是假裝很感興趣。
Thank you so much, Jack. I’m excited to learn more
about mixed reality
and how it can be used to improve our daily lives.
How does our article begin? Well,
we see here that MR,
or mixed reality, is reshaping industries by integrating
digital and physical elements
for groundbreaking applications.
Oh! Groundbreaking is a great term for you to know, friends.
This means that something is new and innovative.
That’s right. For example:
The scientists made a groundbreaking discovery
when they discovered how to break an atom into two parts.
Oh, very exciting. Now,
we’re going to look and see
how mixed reality is being used in today’s world.
We read:
In healthcare,
MR provides realistic simulations,
enabling medical professionals to practice
virtual operations
as if they were working on real patients.
This is really cool.
So when we talk about healthcare, friends,
we are talking about medical services
and different types of treatment.
That’s right. For example,
you could hear this word when you’re
hearing the news—someone saying that
affordable healthcare is important for everyone.
This is really cool
that they found a way to use mixed reality to help
train people.
They don’t have to practice on real patients.
They can practice with a computer—with this mixed reality.
In fact, I think that the medical use of
technologies like this
is probably one of the most positive applications—
or ways of using it.
Now, it’s not all about work, right?
There’s some fun and games in there as well.
We see here that:
In gaming and entertainment,
MR transports users to worlds where they can do anything—
from raising virtual pets
to defending their homes from zombie invasions.
That’s right. Yesterday,
I mentioned that I have used VR once or twice,
and one of those times was when I was playing a zombie
video game.
Now, zombies—as you probably know, friends—
are fictional undead creatures.
These are things or people that are technically dead
but they can still move around.
Yes, that’s right. For example,
in the last 10–15 years,
there have been a lot of movies about zombie outbreaks.
You know, I think I used the word mummy yesterday too.
There are movies about mummies coming to life.
A mummy is just a—
it’s a special Egyptian thing.
The ancient kings of Egypt,
when they died and were buried,
they were wrapped in special cloth and put into those big
pyramids. And those are mummies.
But in lots of movies,
those mummies can come to life
and do all kinds of magical things.
You know, now that I think about it,
mummies and zombies are practically the same thing—
they just look different.
They’re basically the same thing. Now we know!
All right, well—
there are a few more things we want to take a look at here.
We read:
In other industries,
MR enables engineers to experiment with virtual prototypes
within blended environments.
Let’s stop there for a moment and define
this word: prototype.
Prototype means an early version of a product.
Here’s an example:
The company tested several prototypes before launching.
Let’s read this last sentence one more time:
In other industries,
MR enables engineers to experiment with virtual prototypes
within blended environments,
reducing costs and improving efficiency.
So here are two positive things that are coming from
mixed reality.
That’s right.
This way, they’re able to test all kinds of things
without having to build things, throw them away,
and then build new things.
They can do it all digitally.
Now we’re going to go on to hear
about some of the serious concerns
surrounding MR technology in our next reading:
A Whole New World
Unfortunately,
the headsets that make all this possible
don’t come cheap.
Companies like Meta and Apple—
two big rivals in the industry—
are working hard to bring down the costs of their headsets.
But doing so without compromising performance
is no easy task.
Creating a realistic MR experience demands top-of-the-line
hardware and a lot of computing power,
so some of the highest quality devices
are priced at over three thousand dollars.
接下來看 rival 這個名詞，意思是「競爭對手」。
來看例句：
Larry was feeling confident about his popularity at the party until his old rival walked into the room and started making everyone laugh.
Larry 對自己在派對上的受歡迎程度信心滿滿，直到他的老對手走進房間，開始逗得大家開懷大笑為止。
Rival 也可以當動詞，意思是「與誰相媲美」或「比得上」。
譬如：
That man’s loud and deep voice could rival the sound of thunder.
那人的聲音洪亮低沉，可以與雷聲媲美。
如果在 rival 的字尾加上 -ry，rivalry 就是名詞，
意思是「競爭」。例如：
There was a terrible rivalry between the two brothers over who should get their father’s fortune.
兩兄弟為了誰該繼承父親的財產，而爭得不可開交。
Okay, friends,
it is time for us to learn
about some of the disadvantages or concerns
when it comes to mixed reality.
We read:
Unfortunately, the headsets that make all this possible
don’t come cheap.
When you see this phrase “don’t come cheap” or “doesn’t come cheap,”
all that it means is something is very expensive.
That’s right. For example:
High-quality laptops don’t come cheap.
That’s right.
We read on here:
Companies like Meta and Apple,
two big rivals in the industry,
are working hard to bring down the costs of their headsets.
Now, this is exactly the opposite—
“To bring down the costs” means that they’re trying to reduce expenses.
That’s right. For example:
In order to be able to sell something to more people,
maybe a company wants to bring down the costs of production,
or the costs of making it.
Do you think this is true, Dave?
Do you think that Meta and Apple are actually trying
to bring down the costs of their products?
I think yes.
They probably are, because if they don’t bring down the cost,
then they won’t be able to sell as many of them,
and the goal is always to have as many
users as you possibly can.
That makes sense. Well,
how much do these things cost anyway?
Let’s keep reading and find out.
They’re trying to bring down the costs,
but doing so
without compromising performance is no easy task.
Now compromising is a great word for you to know as well, friends.
That’s right.
If you compromise something,
then you weaken it or you put it at risk.
Here’s an example of how you could use compromising in a sentence:
He finished quickly without compromising quality.
That’s right. That’s what we all want to do, right?
Be able to be very efficient,
but still make good quality work.
In our next sentence we see that:
Creating a realistic MR experience demands
top-of-the-line hardware and a lot of computing power.
So some of the highest quality devices are priced at over
three thousand dollars.
This is a pretty expensive piece of equipment!
Now, it’s so expensive because
we’re talking about top-of-the-line hardware.
Now when we say this phrase top-of-the-line,
we’re talking about the absolute best or the most advanced thing.
For example:
Many people feel that Apple’s iPhones are
top-of-the-line smartphones.
Now, Dave, I do have another question about this sentence—
and that’s the word hardware. Can you explain what hardware is?
Yes, of course.
So hardware is the stuff—usually talking about computers—
that is physically inside the computer.
Things like the hard drive, or
the CD drive (they used to have those, right?),
the USB ports—
those physical things that the software,
inside the code of the computer,
is able to make connections with and perform tasks with.
So it sounds like one of the most expensive
parts of these mixed reality headsets is
the actual hardware—
the pieces that are used
to make the actual thing that you put on your head.
That’s right. The gold,
the silver, the glass,
the rare elements—
that stuff doesn’t come cheap.
All right, friends,
we’re not done learning yet, so right now
let’s go to today’s Info Cloud.
Hello everyone,
welcome to Info Cloud!
Carrot,
remember when smartphones were just starting out?
Oh, I do, Rex!
Those early models are nothing compared to today’s phones.
The ones we have today are light years ahead.
I agree! And hey,
that’s such a great phrase.
Light years ahead means being far more advanced
or innovative than others—
like comparing technology now
to what we had decades ago.
Right. Think about electric cars.
Today’s models are light years ahead
of the clunky early prototypes—
better batteries,
beautiful designs,
and in some ways they can even drive on their own!
And it’s not just about technology. For example,
an athlete
who is light years ahead of the competition might be faster,
stronger, and have better strategies.
Yes. A light year is an incredibly huge distance,
so if you’re light years ahead,
you’re far ahead of the competition.
Exactly.
It shows that the bar has been raised far beyond
what we previously thought was possible.
So, friends,
what do you see in our society
that’s light years ahead of what we previously thought might be possible?
light years ahead 遙遙領先 現在的電子科技發展迅速，很多時候會出現創新性的產品。
今天要跟大家介紹的用語是：light years ahead。
字面上就是好幾個光年的距離領先，意思就是非常的先進，把所有的人都拋在後面。
Today, smartphones are light years ahead of the early models.
今天的手機產品已經遙遙領先早期的型號了。
不只是產品，light years ahead 也可以形容一名運動員的實力在競賽當中超越所有對手。
這就是今天的 Info Club，我們下次雲端見！
A Whole New World One of the more serious concerns of this technology
is the issue of data privacy.
MR devices rely on collecting
and processing vast amounts of personal data,
including physical movements,
surroundings, and even biometric information.
Without proper safety measures,
the exploitation of personal data
by bad actors is a dangerous possibility.
While challenges like cost and data privacy remain,
they can be overcome
with responsible development strategies,
allowing MR to enrich part of our daily lives.
今天的 Usage Tip 要來介紹：
one of the / each of the / any of the / either of the 的差別。
名詞的數量有兩個以上的時候，使用 one of the來表示群體裡的其中一個名詞；
如果用 each of the，則表示群體裡的每一個；
如果群體裡有三個以上，則使用 any of the 表示「任何一個」；
而 either of the 則只認一個，但名詞總數「只有兩個」。
這些結構的組詞都被視為單數，所以要搭配單數動詞。
來看例句：
Any of the three options works well for achieving our goals.
這三個選項中的任何一個都能達成我們的目標。
Okay friends,
we have one more section here in this article.
Let’s get into it.
One of the more serious concerns of this technology
is the issue of data privacy.
Yeah, you know,
we talked about this at the end of the program yesterday, right?
And it is something that I think is very important as well.
In our next sentence,
we see that MR devices rely on collecting and processing
vast amounts of personal data,
including physical movements,
surroundings, and even biometric information.
Biometric—this is a term that you need to know, friends.
This is related to body measurements,
such as fingerprints or voice patterns,
and they are used for identification.
I think of unlocking your iPhone with face recognition.
Your iPhone’s hardware and software have to be
able to recognize your face
in order to unlock it.
All that data has to be stored somewhere.
That’s right. Biometrics can be
your face, your fingerprint, for example.
Many phones unlock using
biometric fingerprint data.
Okay, so the concern here is that these MR
systems are collecting large amounts of data
from a lot of different people.
Oh yeah, everything from your body movements
to even the environment that you’re in, right?
If that information fell into the wrong hands,
or even if it was used by ad companies to sell you products—
that’s not fun.
In our next sentence,
we see that:
Without proper safety measures,
the exploitation of personal data by bad actors
is a dangerous possibility.
Quite a few words here for us to talk about, huh?
There’s a lot of things to talk about in this sentence.
Let’s take a look at the idea of safety measures first.
These are actions that are taken to prevent harm—
you’re doing something ahead of time
so that something bad doesn’t happen later.
For example:
The school added new safety measures
so that students knew what to do if there was a fire.
Okay, the next word we need to look at, friends,
is the word exploitation.
This is when somebody takes unfair advantage of something or someone.
Right. This occurs a lot of times in the news.
If you hear about a factory somewhere,
maybe the workers at that factory protested against
exploitation because they weren’t being paid enough.
Exactly.
The last thing we need to look at here is bad actors.
Now, this isn’t someone who is bad at acting—
these are people who cause harm or people who break rules.
Oh! So it’s not someone who’s just bad at acting?
No, this whole time?
No no—but this is exactly as
our teacher Emery said:
a bad actor is someone who has bad intentions.
For example:
Online security protects users from
bad actors who want to steal their data.
All right, let’s finish out the article, friends. We read:
While challenges like cost and data privacy remain,
they can be overcome
with responsible development strategies,
allowing MR to enrich part of our daily lives.
Do you really think that there will come a point when
MR really enriches every single person’s daily life?
I think that it can enrich everyone’s daily life
kind of as something that’s helpful
in the medical field or in scientific development.
If MR can be used to develop a new kind of battery, for example,
that would enrich everyone’s life—not directly,
but definitely because of what it made possible.
Very interesting!
This is a great thing for you to think about
and talk about in English
as we go to today’s Fun Fact.
Hello, Fact Friends!
I am Detective Ernest Finder,
and I have a fun fact for you today.
Did you know that
engineers can use mixed reality to design buildings?
It’s true!
Unfortunately,
buildings must also be built in the real world
before they can be lived in,
so that doesn’t fix all the problems.
But that is today’s Fun Fact!
All right, friends.
It’s the end of our lesson,
which means it’s time for a Talk About It question. Here it is:
If you had an MR headset,
what kind of experiences would you like to have?
I would like to go
like really close to the sun, you know?
Like there’s a special satellite that has all these cool
videos and photos of the sun,
called the Parker Space Probe.
I would love for them to make a virtual experience
using that data—
and then I put on my headset,
and then I’m able to see the sun in all its glory.
That does sound really cool, right?
What about you, friends?
How would you like to experience MR?
Talk about that in English.
Well, that’s all the time we have for today.
My name is Anne Marie.
And I’m David.
And we’ll see you next time,
right here on Studio Classroom.
