We can use it to talk about things in the future
that are probably not going to be true. Maybe I'm
imagining some dream.
Examples
If I won the lottery, I would buy a big house
She would travel all over the world if she were rich.
Structure
if + past simple, ...would + infinitive
First Conditional
It's used to talk about things which might happen in the
future. Of course, we can't know what will happen in the
future, but this describes possible things, which could
easily come true.
