What is a conditional sentence?
Conditionals are structures which express a situation and the possible results.
- If it rains, I’ll stay inside and watch a film.
They consist of a condition clause (if-clause):
- If it rains,
And a main clause (result clause):
- I’ll stay inside and watch a film.
What are the types?
Use the zero conditional to express general truths and facts.
- If I don’t sleep well, I feel grumpy in the morning.

- Grass turns brown if you don’t water it.
Use the first conditional to express likely future situations and their consequences.

- I wish I had studied harder, because if I’d studied harder, I would’ve got a place at a top university.
