The first conditional is used to talk about ...
A possible future situation and its result.
If you go out, you'll have fun.
Be careful - I know the first half looks like the present simple, but it's talking about the future.
We often use this form to make promises or threats, or to negotiate.
I'll buy you a present if I go on holiday. (promise)
I'll hit you if you do that again! (threat)
If you lend me £5, I'll buy you a drink later. (negotiation)
Things to remember:
- It doesn't matter if you say the situation or the result first.
"I'll help you if you want" = "if you want, I'll help you."
- You can use "unless" to mean "if not".
"If you don't help me ..." = "Unless you help me ..."
|Future Situation =|
if + present simple
|Possible Result = |
will/won't + verb
|If you don't help me||I'll be angry.|
|Unless you help me||I'll be angry.|
