Hello!
-
In this video we're looking at mixed conditionals. We've already looked at, in earlier videos,
-
at "I'll go if you go" and "I would go if you went" and "I'd have gone if you had gone".
-
But now we have some new variations - instructions, descriptions and some mixing of different
-
time frames.
-
Hope you enjoy it!
-
We're looking at mixed conditionals and before we do that let's just go back and look at
-
the three, here they are, that we looked at before in three other videos. First of all
-
"I'll go if you go", which is future possibility, I'll just write "possible" there, it's a real
-
possibility. Then "I would go if you went", which is imaginary, I'll write "imaginary",
-
imaginary. And then, finally, "I'd have gone if you had gone" which is the impossible one
-
set in the past but it's impossible because it didn't happen.
-
Now I want to look at some variations, I've got three I want to look at on the left. First
-
of all 'instructions', I'll write "instructions" there and this is where we use the "if" followed
-
by a present tense and an imperative. I'd just like to grab one and pull it in, there
-
it is, that's it: "If it boils, turn the gas down" or "if he calls, let me know" or the
-
other way round "tell me, if you don't feel well".
-
Right, let's move on to the next one now. The next one are 'common events' in present
-
time. Once again I'll grab one and drag it in, there we go: "if you're tired, you need
-
to rest" or another one "if it rains, we stay at home" or a scientific one which it's often
-
used for "if you heat water at sea level, it boils at one hundred degrees centigrade"
-
or if you like "if you heat water at 350 metres above sea level, it boils at ninety-nine degrees
-
centigrade", I think that's right!
-
Now the last one, I'll just write 'present perfect' there, we introduce the present perfect
-
and once again I'll grab another sentence and drag it in. "If you have finished" (which
-
seems to be past present) I'll look at your work". And of course, we could also do that
-
as an instruction so I'll drag in another option there "if you have finished, hand in
-
your paper".
-
Let's move on, I've got three more ways of mixing up conditionals. First of all 'imaginary',
-
I'll just write "again" there, and I'll drag in two more sentences from the right, here
-
we go. "I would go if you should go" or "I would go if you were to go" - two more formal
-
ways of expressing imaginary conditionals.
-
Now the next one, 'common events', I'll just write 'common events' but this time in the
-
past. And here's an example, which I'll drag in, let me get it in the right place, that's
-
it, okay: "if it was fine, we usually had lunch out". Or another one "we wore overcoats,
-
if it was cold" or "we used to take them in by car, if they were late".
-
And finally, the last group I want to put out is when we get a time shift from past
-
to present. That's when the sentence starts in the past and changes to the present, I'll
-
just drag in an example here, get it in the right place...that's ok, good. "If I had worked
-
harder(then), I would be ok now". "If you had saved your money, you would be able to
-
buy a new laptop now".
-
Now, just to finish let's have a look at what Polly thinks about all this. Here she is and
-
what's she got to say? She's got to say: "well perfect...if only".
-
I've given three basic ways of using conditionals; possible, imaginary and impossible and I've
-
given half a dozen variations but the truth is that the way we use conditionals depends
-
on meaning more than grammar and any combination of tenses if alright, if it makes good sense.
-
Now I'd like to move on to a little test.
