  • Doo-doo-doo-doo-doo-doo-doo- -doo-doo-doo-doo-doo-doo-doo.

  • Hello. Hi. James from engVid.

  • You might have noticed that my voice changed. I went from soft to loud.

  • Now, many students I find have a problem when it comes to electronics.

  • They don't know whether they should use, or if

  • they should use "up", "down", "on", or "off". Today is a basic lesson on those things. So,

  • let's go to the board and take a look.

  • Now, when we talk about electronics, which could be something as simple as your cellphone-okay?-what

  • happens is people want to use them, which is fine if you're doing it for yourself, but

  • when you're talking to other people and you want them to do something for you. You notice

  • that this cellphone is, would you say "down" or "off"? All right? That's the lesson we're

  • going to do today. What do you say when you want to change the condition of this cellphone?

  • We'll start right now.

  • E, so are we going to turn up the volume or turn on the volume? Well, I notice

  • "dunh-dunh-dunh-dunh-d- unh-dunh-dunh-dunh-dunh"

  • the music is already on. This is low volume and this is high volume, but how do we change

  • them? Let's start with some basic definitions.

  • First, "turn", that was a turn. It's to move around a centre. Here's a centre, I turn around

  • a centre, or to reverse a position. Interesting. Both of these definitions we need to understand

  • if we say: "turn up" or "turn on". The first one, to turn around a centre, we have to go

  • back in time a little bit. You're from the Modern Age, so when you press your toys, you

  • just press. But when I was a little boy a long time ago, when the Indians rode on the

  • plains... I'm not that old, but I feel that way. What happened was we used to have televisions

  • and radios, and we would turn, we would turn them if we wanted more volume.

  • So if you look over here, where I said turn means to reverse a position, you have 360.

  • So, I feel like we're doing an old science lesson. And boys and girls, we will now demonstrate

  • the turning mechanism. Here we go. We will turn up the power, and turn down the power.

  • Which means reverse. So we're going to look here, and you notice I have to turn. Okay?

  • This is a very old machine. Some of you won't recognize this. It's a film projector. Yeah,

  • we don't use these now. Anyway. But the point was: The technology, you had to actually do

  • something with it, and that's where we get the ideas for "up", "down", "on", and "off".

  • We're switching. We're either reversing the position or moving around a centre.

  • Now, when you have a lot of movement or 360, which is basically a circle... All right?

  • When you have a circle, this is why we talk about turning up and down, because as you

  • turn it, you can increase the power or decrease the power, or make the sound higher or make

  • the sound lower. In fact, in the old days, they used to do this for television, radios,

  • and lights. You would turn up and you would increase it so it would get more. So here's

  • the 360, or you would go more, more, more, more, more. Or you would turn it down and

  • decrease it and you would get less, less, less, less. So the room could be darker if

  • you're talking about light. If sounds all of a sudden the voice would get lower, lower

  • and disappear. Okay.

  • So that's why when we talk about volume on televisions or radios,

  • we say: "Hey, could you turn up the volume?" And if you think about this machine, okay?

  • Turn up the volume,

  • turn down the volume. See? So turning.

  • You don't use it now because we have new machines,

  • but that was what the idea was for English. Now, "turn up", "turn down", you understand.

  • We increase going one way, decrease the other. Higher or lower. And you just think up is

  • more, down is less.

  • So what about the "on/off" thing? On/off. Well, think about it this way: On/off for

  • us is like yes or no. -"Do you want to use it?" -"Yes. Turn it on."

  • -"Do you not want to use it?" -"No. Turn it off."

  • And that's the light switch. When you want to have light,

  • you turn it on. Yes, light. When you don't want it, turn it off. No. Another way of thinking

  • of it is if you like The Avengers, or Hercules from when I was a little kid:

  • "I have the power!" Usually, with electronics, it's about power.

  • When you turn something on, you give

  • it power or electricity, like your lightbulb. And because of that, it goes on and starts

  • to work, and it will continue to work until you take off the power. That's why we say:

  • "Turn on the power", so it can continue going.

  • There is no increase or decrease; it just works.

  • "Attaching", so we say: "We attach power". "Attach" means when you have something, you

  • put it on something so it stays. Now it's attached to my hand. See? Now it's not attached.

  • Well, here is a lightbulb. It doesn't have power, so we attach the power, and then we

  • have light. No li-... No power or no electricity, no light. Lightbulb is off. So that's what

  • we talk about with the "turn on" and "turn off". You want to think: Am I attaching power?

  • Yes? Then you have light. Or not attaching power? No light. "Off" is separating or preventing.

  • When we separate, we prevent the power to go to the light. Because we stop it, there

  • is no light. So this is why we have "on" or "off". Sorry. "On" or "off" for power, and

  • we say: "We're turning on the power", and "turning off the power". But if we want more

  • light, we will turn it up and increase it. Or if we want less light, we will turn it

  • down and decrease it.

  • Now, I'm going to do a little quiz with you, because this was an easy lesson, but an important

  • one. So in the future, the full statement should be: If you want the lights on:

  • "Could you turn on the light, please?" If you want the light off:

  • "Could you turn off the light?"

  • If you want more light, you should say: "Can you turn up the light?" and think of the light

  • going up, up, up; increasing. And if it's too much light, you go:

  • "Could you turn the lights down, please? I just woke up." You'll get less, less light.

  • Ready for the quiz?

  • Let's go.

  • [Snaps]

  • Are we ready? I want to do a quick recap. A "recap" means to go over something again

  • to help you remember. So let's go. So, "on" or "off", we're talking about power. Think

  • "yes" or "no". Do I want it on? Do I want it off? Yes or no? When we turn something...

  • Or sorry, "up" and "down", it's comparative. Think higher or lower. So we turn on the power

  • or turn off the power, like the light. Turn on the light, turn off the light. Okay? When

  • we go up or down, it's comparative, so something is changing in intensity or direction. So

  • it's going higher volume or lower volume. Okay?

  • So we're going comparatively, higher or lower. Cool.

  • Okay? So, let's do some sentences. We have four, here. Okay? First one:

  • "John asked if we had air conditioning because he was hot. I said I would turn it __________."

  • Which one?

  • Now, if John is hot and he's asking if we have air conditioning, probably he cannot

  • hear it or see it. So, I would probably have to turn it

  • "on" because he was hot.

  • If we had air conditioning working, the room would be cool, and he wouldn't have to ask.

  • So we add power to the air conditioning. Yes, we want power, and yes, we want air conditioning.

  • I just turned it on.

  • Next question. Let's go here:

  • "The radio was too loud in the car. Mr. E asked me to turn it __________." "off" or "down"?

  • Well, "too" we talk about

  • how intense or strong something is, and usually we say it's comparative, so higher or lower.

  • Too salty, too much salt. Too loud, too much sound. It doesn't mean we don't like the thing.

  • Or if it's too little, we don't have enough. It doesn't mean we don't like it, it means

  • there's more than we want. We want some, but less. So let's take a look. Comparative over

  • here we have for higher or lower. If the music is too high, we want it lower.

  • That means we want to turn it down.

  • So: "Mr. E asked me to turn it down." Not off, he likes the

  • music, just not so loud. He's got little worm ears.

  • Number three: "The room was dark because the lights were off, so Mr. E turned __________ the lights."

  • This one's a little easy. I want to help you,

  • because if the room were dark, there are no lights. What's the opposite of "off"?

  • Let's take a look. Over here, the opposite of "off" is "on". We need to add power to the lights.

  • So when we add power and turn on the lights, we will be able to see. So:

  • "Mr. E turned on the lights."

  • And number four, what would that be?

  • "While your computer is turned __________, go do the quiz at engVid."

  • Huh? Well, I will leave it for you to think

  • about for a second. Your computer.

  • Do you think you know the answer? Let's take a look.

  • Can you see me? Yes. That means your computer must have power. Correct? That means your

  • computer must be "on". If your computer is on, you can see me.

  • And while you're doing that and it's on, I'm going to suggest that you go do the quiz at

  • www.eng as in English, vid as in video (www.engvid.com), okay? Well, you're probably already there,

  • but if you're on YouTube, go there, do the quiz. See how well you understand the lesson.

  • Okay? Anyway, I've got to go, but I look forward to seeing you soon.

  • And as always, thank you for joining us and don't forget to subscribe.

  • Chao.
