1. First and second conditionals
a) first conditional
If + present simple, will/won't + infinitive. We use the first conditional to talk about a possible or probable situation in the future.
Example: If global warming continues, the consequences will be very serious.
b) second conditional
If + past simple, would/wouldn't + infinitive. We use the second conditional to talk about a hypothetical situation, or to give advice ('If I were you...').
Example: If the Thames Barrier failed, it would be a real disaster.
