Hello, and welcome to Studio Classroom.
My name is Gabe.
And I'm Carolyn.
And your English will improve today.
Today we're continuing our lesson called Don't Forget Your Vitamins.
Yesterday we listened to a conversation between Christopher and Shelly.
Shelly thinks taking vitamin pills is good for you.
But Christopher doesn't like the idea.
He says it's better to get all your nutrients from food, not from pills.
Well, let's continue this story.
Open up your magazines to the page that says "Don't Forget Your Vitamins." Here
we go.
And then we'll spend some time with Michelle in the Language Lab.
(Music).
Don't Forget Your Vitamins.
Well, a good start would be a multi-vitamin.
It has lots of vitamins and minerals in it.
I used to take multi-vitamins as a kid.
Many kids do since they don't eat right.
Which brings us back to my point that people should eat right.
They need a healthy diet.
Taking vitamins and other supplements is not a good substitute for a healthy
diet.
I know.
But people don't always eat what they should.
You're hungry - and where do you plan to go and eat?
A burger place.
But burgers are a good source of protein.
Your body needs that.
(Chinese).
Thank you, Michelle.
Well, we are off to a good start.
And if we go to the top of the conversation, we see what Shelly thinks a good
start would be for Christopher.
Remember, Christopher's complaint is that he doesn't want to take too many
pills.
He complained yesterday also that there are too many to choose from.
I can understand that.
If there are too many choices, you don't even want to start, or at least you're
not sure where to start.
It's just easier not to make any changes.
But I do have to say from personal experience that it's worth the effort just to
do the research and find out what is good for you.
Hmm. Well, what would you suggest for Christopher, then?
Well, he needs to do his research, you know, maybe talk to his doctor, that sort
of thing.
But Shelly's advice isn't bad - take a multi-vitamin.
It has lots of vitamins and minerals in it.
A multi-vitamin.
Well, I like that word.
Let's look at the first part of that word, multi-.
This means there is more than one of something.
There are multiple things.
So there are multiple vitamins in a multi-vitamin.
Now let's look at another common English word that uses the word "multi-." What
about... multitask?
What does that mean, Carolyn?
Oh... moms are good at multitasking.
That means they can do many tasks at the same time.
Uh, can you multitask, Gabe?
Are you kidding?
No! Don't even ask me to try, Carolyn.
I won't be able to focus on one thing if I'm doing many.
But what's another good word that includes the word multi-?
Hmm... multicolored. That means having many colors.
I have a multicolored blanket at home.
That's a good word.
Now there are some other words like this that use the word "multi-" in them.
Well, back to the lesson, multi-vitamins can be beneficial for you.
They have vitamins and minerals in them.
Well, Christopher says that he used to take multi-vitamins as a kid.
And I like that phrase: he used to do something as a kid.
Let's use it in other ways.
Tommy used to go to the beach often as a kid.
OK. Or I used to ask a lot of questions as a student.
Mandy used to solve a lot of problems as a counselor.
Well, there are many ways to use this phrase.
Christopher used to take multi-vitamins as a kid.
Shelly says many kids do since they don't eat right.
Now I like Christopher's next line.
He says: Which brings us back to my point that people should eat right.
Interesting.
His sentence starts with the word "which," but he's not asking a question.
Isn't that strange, Carolyn?
Uh, kind of.
You're right that usually if you see "which" at the beginning of a sentence,
it's going to be a question like:
Which way is the restaurant?
Or which purse do you prefer?
But actually, in conversation, beginning a sentence this way is normal.
Um, it's normal? What do you mean?
Well, think of it as Christopher finishing Shelly's sentence.
Shelly could say many kids do since they don't eat right, which brings us back
to my point.
Because conversations can sometimes seem like a flow of thought, it's OK if they
go like this.
Yeah, conversations are fun like that, friends.
Now I think it's time for us to take a break and let Liz do some talking.
She is waiting for us in the Grammar Gym to talk about this sentence a little
bit.
(Music).
Welcome to the Grammar Gym, friends.
I hope you're all doing well today.
My name is Liz.
In today's lesson we see this statement:
Which brings us back to my point.
That's our Grammar Tip sentence.
This statement is an expression native speakers use to mean that what was just
said matches or supports a point that the speaker has mentioned earlier.
Sometimes a conversation or discussion can cover so many different points.
And if you ever noticed that the discussion is coming back to an earlier point
that you were trying to explain,
then you can use this statement to bring attention to your listeners.
For example, at a meeting you might say:
Everyone seems to think this project is worth doing.
However, people are worried about spending too much money which brings us back
to my point of needing to choose projects that are not too costly.
Or: There are so many places that we can go and visit when we're in Rome which
brings us back to my point that if we want to make the most of our time there,
we need to plan carefully.
So next time when you're in a discussion and you want to bring attention back to
a point that you're making, consider using this expression.
That's all the time we have for today.
Be sure to check out today's Grammar Tip section in your magazine for more
examples.
This is Liz from the Grammar Gym.
See you next time.
Thanks, Liz.
Well, back to the conversation.
Christopher says taking vitamins and other supplements is not a good substitute
for a healthy diet.
It's important to have a healthy diet.
There is no good substitute for a healthy diet.
A substitute is something that takes the place of something else.
I usually think of substitute teachers when I hear this word.
You know, the teachers that come in when your main teacher is away for some
reason.
Substitute teachers were always kind of scared for some reason.
That's because your classmates didn't treat the substitute nicely, Gabe.
Hmm, maybe you're right about that.
Well, this word "substitute" can be a verb as well.
You can substitute one thing for another.
But don't substitute vitamins for a healthy diet.
You still need to eat healthy.
Well, Shelly responds to Christopher by telling him don't... that people don't
always eat what they should.
She is thinking about Christopher and what he wants to eat.
That's right.
He wants to go to the burger place, remember?
He thinks that's perfectly OK.
He says burgers are a good source of protein that your body needs.
I agree with him.
Meat is great protein.
Eggs, fish, milk and peanuts are all great sources of protein.
Well, I like the phrase in that sentence: a good source of protein, a good
source of something.
You could use that phrase to talk about other things.
For example, I think it's important to have a good source of entertainment.
There are so many movies and TV shows that are not good for us to watch.
We should think of good sources of entertainment.
Like Studio Classroom.
Well, this is more of a good source of education than entertainment, but it is
certainly entertaining at certain moments.
Speaking of, I always enjoy our time in the Information Cloud.
Let's go there now.
Hi, friends.
What would you order from a burger place?
Why, a hamburger, of course!
What if you don't feel like eating beef?
Maybe you can order a fish burger or a chicken burger.
Many burger places offer sandwiches other than burgers, such as chicken or fish.
But strictly speaking, if you order anything other than something with a beef
patty in it, it's called a sandwich.
Many burger places also offer chicken sandwiches, fish sandwiches and seafood
sandwiches, even though they are served in a bun like a hamburger.
Now you will see the word "burger" used with non-beef sandwiches in various
places.
But in the United States, traditionally, the word "burger" has always referred
to a hamburger or a cheeseburger.
Now speaking of hamburger, Ken, if you go to the supermarket, could you please
pick me up some hamburger?
Sure. I can pick up some ground beef.
Are you making spaghetti sauce?
Yes! That's the plan.
Friends, did you catch that?
The word hamburger, when used as an uncountable noun, refers to ground beef
which is uncooked.
Ken will go to the grocery store and buy a pound of hamburger.
And what he'll get is beef, ground up.
