cases, they're probably using a look after when they should be looking using

look at. So let's take a look at the note here. If someone looks after a person

they take care of them, help them , make sure they don't get into trouble or hurt

themselves. So if you're looking after someone maybe they're sick. Maybe they

need your aid. Maybe it's small children. Maybe it's an elderly person that has

difficulty to gett around. You might look after them to make sure they're okay.

Make sure they don't get into trouble. If someone looks after something, he or she

makes sure it is protected, not lost, not damaged , not stolen. You know, so you ask

somebody to look after something for you. You want them to mind it for you, make sure

just hold it for you. Make sure nothing bad happens to it. So

you want somebody to look after something. All right. Now if we say look

at. Let's continue here. If someone looks at something , well in this situation, they

check it to see what is wrong and try to fix it. Yeah of course you could say, look

at me and just directly look at someone too, but that's not the meaning we want here. We want this meaning.

So like if you call someone to look at something, you want them to check it out.

See if there's a problem with it. See what's wrong with it. Okay, so let's look

at the first example where it's wrong. Of course here with the X, this is wrong.

That elevator is out of order. You should call someone to look after it.

Yeah. So this would be a mistake that a student might make. It would sound

very strange, if you say call someone to look after the elevators. You know what is he going to do ? Oh are you okay ?

Do you need any help ? Is that what the mechanic is going to say to the elevator ?

So of course, you wouldn't really be looking after it

you should, the correct way to say it is would be this. That elevator is out of order. You should

call someone to look at it meaning to check it out. See what the problem is ? See why it

doesn't, why it's not running or operating correctly. What needs to be

done in order to fix it. You want him to look at it. Good. Let's look at the second one here . Again with

the X. This is wrong. The air conditioner is not working well. Can you call the

landlord to send someone to look after it ?

Again you don't want someone to like babysit or look after your air

conditioner. You want them to check it out. So of course, the correct way is to say

it, you know with the check here , would be the air conditioner is not working well, can you call

the landlord to send someone to look at it ? To check and see why it's not running

correctly or properly. What needs to be done to fix the problem. So in that case

you should say to look at it. Check it out. Okay good, and of course , we just give one example here.

Where we do want to say to look after. I asked my sister to babysit and look after my children for a couple of days when I had to have an operation. . Yes. You wanted her to

mind them. Make sure they're okay. Make sure they're healthy, make sure they

don't get into trouble, hurt themselves or something like that. You

wanted , she wanted her sister to look after her children. Yeah. Look at means

there's usually a problem that you want someone to check. We could use look at

to think if somebody has a health problem. They might go to the doctor and

you want the doctor to look at it. Maybe you had an infection or a sore or

something like that on a part of your body you want the doctor to look at it.

So you want him to check it. You want him to see what's wrong with it ? How can he

treat it to make it better ? That would also be to look at it. All right. Anyway, I hope it's clear. I hope you clearly see the difference between the two now. Thank you for your time . Bye-bye.
