Review:
POSSIBLE IN THE FUTURE (first conditional): If my boss ASKS me to go to London, I WILL accept.
- There is more than a 50% chance that my boss will ask me.
NOT POSSIBLE, IMAGINE (second conditional): If my boss ASKED me to go to London, I WOULD accept.
- My boss will never ask me. It’s not possible so I just imagine.
THIRD CONDITIONAL (PAST EVENT): If my boss HAD ASKED me to go to London, I WOULD HAVE ACCEPTED.
- It is too late, he asked someone else, and the offer is over.
