Today, we start with the word EVALUATION.  Evaluation. A longer word, five syllables,  

with stress on the fourth syllable. Evaluation.  Evaluation. Noun, a careful, thoughtful judgment  

of something or someone. The teacher received  five star evaluations from every student.  

Let's look again up close and in slow motion. And now, we'll go to Youglish for five examples. 

Parents and the community should  have input into the evaluation. 

She's talking about a bill that was  being voted on regarding evaluating  

teachers. Making thoughtful judgments of  teachers and their skills in the classroom. 

Parents and the community should  have input into the evaluation. 

Here's another example. Now, we're going to do a  

little bit of evaluation, a little bit of  what we call naming and framing the ideas. 

A little bit of evaluation. A little bit of  judging, naming it good, bad, this idea is  

good for this, and so on. Evaluating, carefully  considering something, then making a judgment. 

Now, we're going to do a little bit of  evaluation a little bit of what we call  

naming and framing the ideas. Here's another example. 

After the program, we invite you to fill in  the little evaluation forms that you see. 

Evaluation forms. This is to give feedback  to the people running the program.  

What was your experience in the  program? What did you think of it? 

After the program, we invite you to fill in  the little evaluation forms that you see. 

Another example. We did a formal evaluation of how  

people run and compared running styles in normal  gravity to running styles up on the space station. 

A formal evaluation. They must  have come up with a method,  

specific things they were looking at, in each  runner, to make a judgment on running styles. 

We did a formal evaluation of how people run  and compare running styles in normal gravity to  

running styles up on the space station. Our last example. 

Physical therapy evaluation and treatment can  certainly help with balance and walking issues. 

Evaluation, study and judgment of how good  someone's balance is. And if it's not good,  

some physical therapy to make it better. Physical therapy evaluation and treatment can  

certainly help with balance and walking issues. Our next word is POSITIVE, with a flap T.  

Positive. It's an adjective, good or useful.  The book had a positive influence on me.  

It also means completely certain or sure  that something is correct or true. We were  

positive that we would win the game. Let's  see that again up close and in slow motion. 

And now we'll go to Youglish for five examples. Choose to make a positive difference. 

A positive difference. The opposite is negative.  Every moment you get to choose will you make  

a positive difference. Remain neutral,  a negative difference. Hurt someone or  

a community, most people don't actively  choose to make a negative difference,  

but a lot of people make no difference at all.  What would it take for you to make a positive  

difference in someone's day, or a positive  difference in, say, your local elementary schools? 

Choose to make a positive difference. Here's another example. 

And there were some very positive, you  know, benefits that came out of that. 

Very positive benefits. You do one thing,  and these other great things happen.  

These other useful things happen. And there was some very positive,  

you know, benefits that came out of that. Here's another example. 

For the most part, this is a positive thing. This is a positive thing.  

This is overall good, useful, desirable. 

For the most part, this is a positive thing. Another example. 

Can a person test negative and then  later test positive for Covid-19? 

Testing positive for Covid-19, that is you  take the test and the results show that  

it is certain that you do have Covid-19. Can a person test negative and then later  

test positive for Covid-19? Our last example. 

Hey, just be positive, we're  gonna get through this.

Just be positive. This is about your  mindset. How you choose to see the world  

and approach things. Can you still be positive  even when times are tough, even when life is hard?  

That might make it easier to get through it. Hey just be positive,  

we're gonna get through this. Our last word today is SECURITY with a flap T.  

Security. It's a noun, the state of being,  protected or safe from harm. Things done  

to make people or places safe. Going through  airport security usually takes about 45 minutes.  

Let's see it again up close and in slow motion. And now we'll go to Youglish for five examples.

You see, our national security is  dependent upon our food security. 

National security. As a nation, how safe  are we? How safe for our food sources? 

You see, our national security is  dependent upon our food security. 

Here's another example. Well, if you imagine that I was keeping, you know,  

50 billion dollars worth of stuff on a big Google  spreadsheet, we might have some security concerns. 

Security concerns. Is that a safe way to keep that  information? Or could it get into the wrong hands? 

Well, if you imagine that I was keeping, you know,  50 billion dollars worth of stuff on a big Google  

spreadsheet, we might have some security concerns. Here's another example. 

And the kid was drinking it and a security  guard spotted it and called the police. 

A security guard. Someone hired  to keep a building or place safe. 

And the kid was drinking it and a security  guard spotted it and called the police. 

Another example. So we now have 24-hour  

security and surveillance of our vehicles. 24-hour security. This could mean an alarm  

that would go off if the cars are broken into  or damaged, along with surveillance. Someone  

monitoring visually either by being there  or watching through a camera and screen. 

So we now have 24-hour security  and surveillance of our vehicles. 

Our last example. The money is more than just money, it's security. 

More than just money. It's security. Having  money makes people feel secure, feel safe,  

and protected, because they know if something  happens, they might be able to fix it with money.  

For example, if you lose your job,  but you have a big savings, that will  

be less stressful. You'll feel less worried  about paying your rent, feeding your family,  

and so on. You'll feel more safe and secure. The money is more than just money, it's security.
