Hello, everybody.
Welcome to Studio Classroom Worldwide.
My name is Steve.
And my name is Kaylah.
Well, Kaylah, are you feeling OK?
Well, yes, I feel fine.
Why?
Because you are wearing a face mask.
Oh, right.
I walked to work today.
And there was a lot of pollution.
Oh. So you wore the mask to help keep the pollution out.
Exactly.
Hmm. So does it work?
Do you mean does it actually block pollution?
Yeah.
Well, at least a little bit of it.
And then I don't cough as much.
Ooh. Well, that's good.
But I don't know how much of this "face mask" theory I really believe.
Well, Steve, you should join us all on page 35 to learn more about Face Masks.
(Music).
Face Masks.
A shield against germs.
People around the world make strategic decisions about how to live a healthy
life.
In some countries, people who think they are getting sick eat more citrus fruits
like oranges, increase their intake of water or take vitamins.
In other countries, people wear masks over their faces in an attempt to filter
out germs from their environment.
The idea that tightly woven fabric can purify the air that people breathe goes
back to Leonardo Da Vinci, who introduced the idea in the 16th century.
Since the early 19th century, inventors have been creating masks while gradually
improving their design.

Hello, friends.
My name is Ryan.
And my name is Kaylah.
Today we are talking about Face Masks.
Now Ryan, this is kind of an odd thing to talk about.
We don't usually talk about a face mask.
Yeah. But it's probably an important thing to talk about, Kaylah, since they are
so useful.
Usually people wear face masks, like you can see on page 35, as a shield against
germs.
Now earlier this month we did talk about a shield as a... piece of material that
you carry to protect you.
Here it is some sort of material that is worn on your face over your mouth and
your nose to protect you from the air,
or even sometimes to protect the air from you.
Hmm. That's a good point, Kaylah.
People wear these face masks around the world.
And they make a strategic decision about how to live a healthy life.
Now Ryan, I know when I visited Asia for the first time was really the first
time I saw so many face masks.
That's true.
Face masks are worn much more in Asia than they are in the West.
And that's because people in Asia have a certain purpose: They want to protect
others from their sickness.
That's right. It is a strategic decision on their part.
That's right.
And something that is "strategic" is done to help a plan, to help achieve a
goal.
And of course, if you're wearing a face mask, that goal is to keep others from
getting sick.
You know, in some countries, people who think that they are getting sick eat
more citrus fruits, like oranges.
They increase their intake of water or vitamins.
So there are different things you can do.
In some countries depending on where you live depends on how you react.
That's true. How some people are raised might make it different how they treat
themselves or how they treat others when they get sick.
Of course in the West, it is pretty common to have some citrus, take your
vitamins and maybe stay at home and rest.
That's right.
And drinking lots of water also is a good way to help really any sickness you
might feel coming on.
In other countries, people wear masks over their faces in an attempt to filter
out germs from their environment.
Yeah. And that's a good thing to do.
It's a reason why most people wear masks - to filter out the air.
If something is filtered, that means that it is blocked from certain objects
that are in the air.
You take some things out, usually the bad things.
That's right. If we think about maybe an air conditioner, they have a filter in
it that keeps the dust and dirt from coming in from the outside.
So that is exactly what this idea of using a face... face mask is for.
Exactly. It's, of course, to protect you from dirt and other small bits of
things in the air but also germs.
Those can get blocked or filtered as well.
Now the idea that tightly woven fabric can purify the air that goes... that
people breathe in goes all the way back to Leonardo Da Vinci,
who introduced the idea in the 16th century.
So this does come from a long time ago uh, in order to "purify" something.
And that means that you remove all of the bad substances from it so that it is
pure.
There's nothing bad in it.
That is true.
And he thought that using tightly woven fabric - now that's when the threads in
the fabric are very close together - so that only small... like the smallest,
small... things can go through.
So it captures pollution; it captures germs from getting inside because it's so
tightly woven that only air can pass through.
Right.
This is the idea.
Exactly, yeah. And if something is woven, it means that the different strains
like in cloth pass over each other.
And that means that only air can go through, not those little bits of things.
That's right.
And that is our Grammar on the Go sentence, so let's visit Liz.
Hi, friends.
Greetings from Venice, Italy.
I hope you're all doing well today.
My name is Liz, and it's time for Grammar on the Go.
In our article today on Face Masks, we read:
The idea that tightly woven fabric can purify the air that people breathe goes
back to Leonardo Da Vinci, who introduced the idea in the 16th century.
Notice the pattern: the idea that... goes back to.
That's our Grammar Tip focus for today.
We use this pattern when we want to explain where an idea came from or when it
was first developed.
In the case of today's Grammar Tip sentence, the writer is saying:
The idea of wearing masks to purify the air comes from Leonardo Da Vinci.
This sentence pattern can be used to explain different things.
We can use this sentence pattern to talk about holiday traditions.
For example:
The idea of celebrating Dragon Boat Festival goes back to the time when the
famous poet Qu Yuan drowned himself and people threw dumplings into the river to
keep the fish from eating his body.
We can also use the sentence pattern to talk about scientific ideas.
For example: The idea that Earth is round is much older than what most people
think; in fact, it goes back to the time of the ancient Greeks.
And that's all the time we have for today.
Thanks again for joining me here in Venice.
This is Liz with Grammar on the Go, signing off. Bye-bye.
Thank you, Liz.
So the idea of a face mask has been around for a very long time since the 16th
century.
That's right.
And since the early 19th century, inventors have been creating masks while
gradually improving their design.
So we've had masks since the 16th century, but we keep making them better all
the time.
Exactly, yeah. We have plenty of masks in use today.
And they continue to become more and more prevalent.
They are easy to find.
But they've always been around for a long time.
That's right. They are improving across the time.
As we improve in technology, so do face masks.
Now Ryan, when have you used face masks?
Oh. Well, actually I didn't use them much until I moved to Asia.
Since they are used more here, I began wearing them when I would become sick to
protect other people.
Well, I most commonly have worn them when I work on a job site doing
construction work to help protect your lungs from dust.
So these masks have a lot of uses.
And we're going to talk about how they are improving and the many uses of them
after the break.
But before we go, let's see today's skit.
Hello, Amanda.
Hello. Is that you, Hazel?
Yes, it's me.
Why are you wearing a mask?
(Background Noise).
What did you say?
(Background Noise).
Sorry. I can't understand you.
Take off the mask.
I said I've made a strategic decision.
What decision is that?
I'm going to live a healthy lifestyle.
So that's why you're wearing the mask?
Yes, I'm filtering out germs from the environment.
Where did you get that idea?
Leonardo Da Vinci. He introduced it in the 16th century.
People in some professions wear masks.
Construction works, farmers, doctors.
But you?
Yes. I don't want to breathe in particles of dust, germs or pollution.
So will you wear the mask all the time?
Yes, especially in crowds.
Amanda, you should wear one too.
No, thanks.
Masks are uncomfortable.
Yeah, sometimes they fit too snugly.
I'll just eat more citrus fruits, drink more water, take vitamins.
Is that part of a healthy lifestyle too?
Yes, and fruit is delicious.
But you can't eat it wearing a mask.
Oh.
Well, forget about the mask.
I'll eat fruit instead.
Can I have one of your oranges?
Sure! Here you go.
Thanks!
