Conditionals
1. The zero conditional expresses situations that are always true and refers to «all time», not just the present or future. We use the zero conditional to state things that seem generally or always true such as rules, scientific and economic laws, religious doctrines, guidelines.
1) If we don’t water the flowers at home, they die.
2) If I drop an egg, it breaks.
3) If it rains, you get wet.
4) If you heat water to 100 °C, it boils.
We use a comma when the if-clause is the first but when the if-clause follows the main clause, we don’t use a comma.
1) Flowers die if you don’t water them.
2) An egg breaks if I drop it.
2. We use the first conditional to talk about things that are normal, possible and may happen in the future as a result of a possible action or situation. We use the first conditional to give some advice or warnings, to make predictions, offers or promises, to state instructions, to draw conclusions.
1) If you come to me, I’ll help you with your project.
2) If you aren’t too tired, you can (you’ll) take part in our competition.
3) If you press button B, the TV set will be switched off.
4) If the weather is fine, we’ll go for a walk.
3. We use the second conditional to talk about things that are impossible or unlikely to happen. We use the Past Simple to describe an imaginary action or situation in if-clauses and would + verb to describe the result.
1) If you came to me, I would help you with your project.
2) If you weren’t too tired, you would (you’d) take part in our competition (you could take part in our competition).
3) If you pressed button B, the TV set would be switched off.
4) If the weather was fine, we would go for a walk.
4. We use the third conditional to talk about events in the past that cannot be changed, about things that might have happened in the past but did not.
1) If you had come to me, I would have helped you with your project.
2) If you hadn’t been so tired, you would (could) have taken part in our competition.
3) If the weather had been fine last week, we could (would) have gone for a walk.
