hi guys i'm Arnel from A rnel's Everyday
English and today we're looking at could have
may have might have must have should have and would have. I know all of
this looks a bit overwhelming, but today we're going to do
it in bite-sized pieces. First
we're going to look at could have, may have and might have
together. We're going to see the connection with
must have then we have should have and finally would have. What we also need
to do is look at something very important:
Pronunciation! Native speakers get really lazy when they use these.
So at the end of the lesson, I'm going to take a couple of minutes
to show you how to be really lazy too. First things first: Could, may,
might, must, should and would, are what we call
modal verbs. Modal verbs have so many different uses
and it's really important to remember that throughout today's lesson,
because, today we are specifically looking at
past modals. These modals plus have plus the past participle.
What's the past participle? Let's do a little review.
Walk, walked, walked, that verb number three is the past participle.
Swim, swam, swum. Swum is my past participle.
So in today's lesson if I say past participle or verb
three, you know i mean this form there. Could have, may have, might have.
Past possibility. I am guessing. I don't have all the information.
We see my timeline there's a past and the present.
Where's Julie? She could have gone home, I mean at six
o'clock. She might have gone home. She
may have gone home. This is a past possibility.
I am guessing, I don't have all the information.
Maybe Julie went to the bathroom. Maybe she went out to grab some dinner and
she'll be back, I'm not sure. You can see here
even though my subject is she, I still use
have. She could have gone home, we would never say:
she could has gone home. Where's my shopping bag? I could have
left it in the cafe. I might have left it in the
cafe. I may have left it in the cafe. This is a
past possibility. I am guessing, I don't have all the
information. Maybe i left my bag on the bus. Maybe my
husband took it home with him. I'm not really sure. So
what's the difference between could, may and might? When we are speaking about
past possibility you can use these interchangeably.
Some people say may is a bit more formal. Some people say may is more...
the possibility is a bit higher. But really don't worry about that difference,
use these three freely. Great. So you know she could,
might, may have gone home. You know this is a past possibility,
and you can use these in the same way. If we want to speak about something
where we had the option but we chose not to do
something, you can use could. I could have gone to a hair salon,
but i decided to cut my hair myself, to save some money! We could have stayed longer but i was
getting a bit chilly, so we decided to go home.
There was a past option but we decided to do something different.
Use could have or might have to say something didn't happen. Normally
we use this structure to show relief, we are relieved something
didn't happen. I am so glad my son was wearing his
helmet, he could have been really hurt. He might
have been really hurt. In this case we would not use may have. Okay, let's take a look at this line here.
Now let's have this question: Hey! Do you know
Hannah locked up last night? When i say locked up it means
lock up all the windows and doors before closing a business for the night.
So in my example, this is one colleague speaking to another.
I have actually happened 100% fact. Yes, Hannah locked up last night. I was
with her, and i saw her do it. I have
didn't happen 100% fact. No, Hannah didn't lock up. We both left the
office at four, and there were other people still
working. Here in the middle I have: maybe happened.
Hannah may, might, could have locked up last night.
I'm not sure, I left the office at four but there were still a few people
working - including Hannah. Hannah must have locked up last night.
I left the office at four and she was the last person there.
Okay, now i have must have plus past participle.
You can see on my line, must have is very close to 100%
fact. This is because I am almost certain this happened.
Hannah was the last person in the office but i didn't see her do anything.
My kids must have eaten the last slice of cake.
My husband doesn't really like cake, so I'm pretty sure it was the kids.
Carrie isn't here, she must have missed her flight.
I can't think of any other reason she isn't here. Philip didn't answer my call, he must
have been sleeping. It was 11 pm so there is a very high
probability he was sleeping. In the negative some
things are different. May have, may not have.
Might have, might not have - okay! Must have, mustn't have - okay!
Could have, okay couldn't have, impossible! You can see the position
changes from: maybe. Yes, can't have is another option.
Remember, can't have plus past participle is okay,
but we do not say can have plus past participle.
Hannah could have locked up, maybe. Hannah couldn't have locked up, she left
work at three. I really don't think this is possible. Okay! You have done an amazing job with
could, may, might, and must have. One thing you
can do to make this easier to remember is to write example sentences, personal
example sentences, this will make things easier to remember.
Should have plus past participle. Expectation. Regret.
This is better. Pete should have landed by now. He should have
landed 30 minutes ago. He should have called me.
These are things I was expecting to happen, now i'm waiting.
I'm not really sure if he's landed or not. Regret. I should have studied English
sooner! A lot of students say this.
I shouldn't have spoken to my mom like that,
I was angry. This is better. I feel gross. Well, you shouldn't have
eaten eight donuts. What's better? Not eating eight donuts
is better than what you did! You're an hour late,
you should have called me. Calling me is better than what you did - what you
didn't do, you didn't call me! They shouldn't have increased their
prices, I think they lost a lot of customers.
Here, what's better? Not increasing prices. In this structure here, this is better,
it's kind of like you're giving past advice.
Or possibly even criticism. You should have done something, differently.
Would have plus past participle. Hypothetical past.
Hypothetical means not real, imaginary... Okay, the unicorn is a bit much but you
know what I mean. Not realistic. I would have gone to the
gym this morning, but my back was hurting a little bit. Why
is this hypothetical? Because in reality, I didn't go to the
gym. I decided not to give my teacher the
card i made. Why not? She would have loved it! This is
hypothetical, because in reality the child didn't give
the card to his or her teacher. If he had given his teacher the card she
would have loved it. Some of you know this as a third
conditional. Don't worry, today is not a lesson about
third conditional, and you don't need to know the third
conditional to use: would have plus past participle
correctly. Let's do a few more examples together. I
ordered a shirt online but it had a hole in it, so i threw it
away. You threw it away? I would have returned
it. I am not you,. this situation didn't
really happen to me It's so good you didn't tell Brian you
used his car, he would have gone crazy. You didn't tell
Brian, in reality, nothing happened.
Fantastic, let's keep going, we're on the home stretch now.
Could have, may have, might have, must have, should have, would have.
Okay, so we have these forms here throughout the lesson I've been using
the full form: could have plus past participle, may have plus past
participle. But in spoken English, we normally
contract everything. Could've, may've,
might've, must've, should've, would've. I'll do that a bit faster:
Could've, may've, might've, must've, should've, would've. If you think that
sound is a little bit difficult, try to think about it like:
of. Could of, may of, might of, must of, should of,
would of. Just so you know, of is not correct, it's just the sound, we
would never write could of. You know what, we are busy people, we
don't even have time to say of sometimes. Let's get a bit lazier! Coulda, maya, mighta, musta, shoulda, woulda. Let's do that again a little bit faster: Coulda, maya, mighta, musta, shoulda, woulda. Just add that a the end and you know
it's the really lazy contracted form of could have. She coulda gone home,
she maya gone home, she mighta gone home,
she musta, gone home she shoulda gone home,
she woulda gone home. In the negative: Couldn't've,
mightn't've, shouldn't've, wouldn't've.
You can see i skipped may, we would never say
mayn't've that's very unnatural, so you don't need to worry about that one.
There you go, we've looked at all of these modal verbs
in the past with that have and verb number three.
So whenever you're watching a movie or you're reading a book
really listen out, or look out for, these forms.
The more you see it the more comfortable you'll feel.

Leave me a couple of examples in the comments below, personal
examples, easier to remember. Have a wonderful day and i'll see you soon. Bye!
