Hello, and welcome to Studio Classroom.
My name is Gabe.
I'm Carolyn.
And I'm Nathanael.
And we want to thank you for joining us for the second day of or lesson Eat for
Energy.
We're glad that you joined us today because we haven't finished talking about
important foods that you could eat so that you can have energy.
Yesterday we were talking about what happens when your mind starts to wander
when you're working.
And then the pain in your stomach reminds you that you need to get back to work.
But you need energy, well, Nathanael, what can you do?
Well, one thing that you can do is to make sure that you drink enough water.
Water keeps your cells working as they should, and also allows you to absorb the
things that you need for your body.
That's right.
So water is one thing we talked about yesterday.
But Carolyn, what was the other kind of food that you could have?
Well, you could also have a little snack by eating some almonds.
Almonds are great for protein, which helps to give you energy.
And almonds also contain omega-3 fatty acids, which are great for your heart and
help you to stay focused.
So you could have almonds or drink a glass of water.
Well, maybe you want to go and get a glass of water, a bag of almonds right now
and enjoy the second part of our lesson today.
Let's get started with the first reading Eat for Energy.
(Music).
Eat for Energy.
Fruit.
Fruit of all kinds contain healthy carbohydrates, which will raise your energy
level quickly.
They have fiber, which will fill you up, and lots of vitamins.
Bananas make especially good snacks because they have lots of potassium.
This important mineral keeps your nerves and muscles working well.
Whole grains.
Whole wheat, oats and brown rice give you fiber, good carbohydrates and
vitamins.
They provide energy that will stay with you until your next meal.
So this is the third suggestion of something that you can eat or drink to give
you some energy - fruit.
Fruit of all kinds contain healthy carbohydrates, which will raise your energy
level quickly.
So we have this word "carbohydrates," and we just want to learn about that
little bit more.
What's the most important thing to know about carbohydrates, Carolyn?
Well, a carbohydrate can also be called a "carb," very commonly in English.
And it's just something that gives your body more energy, so.
Lots of breads, grains, rice have lots of carbohydrates, and your body uses this
to stay energized.
That's right.
And carbs, or carbohydrates, can also be found in sugar or different things made
from sugar like desserts.
They often have carbohydrates.
And of course, after you eat a nice, sweet dessert, you might feel a boost of
energy.
OK. And I think there's a little bit more for us to learn about fruit in the
Information Cloud.
Our lesson today tells us that fruit of all kinds contain healthy carbohydrates.
Have you ever wondered why it written "fruit" and not "fruits"?
Well, although it's true that both "fruit" and "fruits" are acceptable plural
forms, most native English speakers prefer the singular form.
For example: Fruit is delicious in the summertime.
And if I say "fruits" are delicious in the summertime, it would not be
considered wrong, but it just sounds kind of scientific.
Hmm, yes. I agree, Ken.
If you're a botanist who studies different varieties of fruit, then you might
call different berries and nuts fruits.
So "fruit" is the overall description.
And if you want to refer to individual types or names of fruit, you can use
"fruits" with a S.
Right.
Now Ken, there's another place where the plural "fruits" is used.
And that is when you use "fruit" as a symbol as in "the fruits of my labor".
Right. In that usage, fruit is no longer what's harvested from trees but a
symbol.
Fruits means "benefits" in that expression.
So the next time you can't decide whether to use fruit or fruits, go with
"fruit." It's what most people say.
(Chinese).
Continuing in the article the next sentence says:
They have fiber, which will fill you up, and lots of vitamins.
So fruit has fiber and vitamins as well.
Now "vitamins" is an important word today because it is a Word Bank word that we
want to talk about.
What should we know about vitamins, Gabe?
Well, something is that we need all kinds of vitamins.
Our bodies need every kind of vitamin.
A lot of vitamins come from things like animals and plants.
And of course, maybe you can think of some vitamins, like vitamin C.
You can eat or drink uh, lemonade, and get some vitamin C.
That's very important if you want to stay away from getting a cold.
What else do we know about vitamins, Carolyn?
That's right.
Well, fruits are filled with vitamins many different kinds, but one kind they
don't have is B12.
B12 is a vitamin that is only found in animals.
So if you don't eat a lot of meat, you might want to take a vitamin, which is
just a small pill usually, and it will give you the B12 if you need more of it.
Yes. Vitamins are something else that your body cannot make itself, so you have
to eat them.
OK. Now we have another specific fruit that is mentioned.
What is that fruit, Gabe?
The fruit we see here is banana.
We find that bananas make especially good snacks because they have lots of
potassium.
So of course, if you like bananas, then this is great.
And they make especially good snacks.
Let's take a look at that phrase there: if something makes especially good
something, it makes a good something.
You could use this phrase in another way.
You could say songs make good English lessons.
You can listen to songs just for fun, or you can learn to... listen to English
songs and learn something new.
But Carolyn, how else could you use that phrase?
Well, you might be thinking about getting a pet, and oh, what kind of pet should
I get?
Well, dogs make especially good pets.
So do cats; so they make good pets.
How else can you use this, Nathanael?
Well, I was thinking of possibly talking about a writer, you might say that his
books make for good movies or make good movies.
I like when they make movies out of his books.
OK. The next sentence of this article says:
This important mineral keeps your nerves and muscles working well.
Now of course, this important mineral is potassium.
And now we want to talk about this word "mineral." Mineral is another Word Bank
word for today.
And what is important about minerals, Carolyn?
Well, minerals are natural substances found in nature such as salt or coal or
even gold.
These are all different kinds of minerals.
What else do you know about them, Gabe?
Well, most minerals come from things like soil or water.
So you found out that vitamins come mainly from plants and animals, minerals
come from the earth like soil and water.
Now you don't need every kind of mineral, but you do need all kinds of vitamins.
But we do find out that potassium is a great mineral that is found in bananas.
So if you want some energy, do have a banana.
OK, so we've talked about fruit.
Now let's talk about the next example, which is whole grains.
First sentence of this section says:
Whole wheat, oats and brown rice give you fiber, good carbohydrates and
vitamins.
A lot of words that we've seen there already.
Do you eat much whole grain, Carolyn?
Well, usually if I have a sandwich, I try to use whole-grain bread instead of
white bread because it does have more fiber.
And it's a little bit better for you.
Now if we continue in the article, it says:
They provide energy that will stay with you until your next meal.
And this is important if you do not want to feel hungry later in the afternoon.
OK. These are some great suggestions.
Maybe you should consider them.
But right now let's go to the Language Lab and talk to Michelle.
Hi, everyone. I'm Michelle.
