The Zero Conditional

The Zero Conditional

1. If + present simple, .... present simple.

2. This conditional is used when the result will always happen. So, if water reaches 100 degrees, it always boils. It's a fact. I'm talking in general, not about one particular situation. The result of the 'if clause' is always the main clause.

3. The 'if' in this conditional can usually be replaced by 'when' without changing the meaning.

4. If I eat peanuts, I am sick. (This is true only for me, maybe, not for everyone, but it's still true that I'm sick every time I eat peanuts)
