4. Zero Conditional and First Conditional

The zero conditional describes what happens in general whereas the first conditional describes a particular situation.

For example (zero conditional): If you touch fire, you get burned (here I’m talking about every time a person touches fire – the burning is a natural consequence of touching).

But (first conditional): If you the fire, you’ll get burned (here I’m talking about what will happen with this specific fire).

5. First Conditional and Second Conditional

The first conditional describes things that I think are likely to happen in the future, whereas the second conditional talks about things that I don’t think will really happen. It’s subjective; it depends on my point of view.

For example (first conditional): If he studies harder, he’ll pass the test (I think it’s possible he will study harder and so he’ll pass).

But (second conditional): If he studied harder, he would pass the exam (I think that he won’t study harder, or it’s very unlikely, and so he won’t pass).
