There are four types of conditionals: 0 Conditional, 1st Conditional, 2nd Conditional, and 3rd Conditional. In Part 1, we will take a look at the 0 Conditional and the 1st Conditional, which both use present tense verbs.
We use the 0 Conditional to talk about general truths - situations that are real and will definitely happen. The form of the 0 Conditional is: If + present tense verb, + present tense verb.
- real condition → definite result
- If water reaches 100 degrees, it boils.
The 1st Conditional is less certain than the 0 Conditional, so it talks about things that will probably happen. The form of the 1st Conditional is: If + present tense verb, + 'will' verb.
- possible condition → probable result
- If you wear a sweater, you will be hot.
Conditionals as Imperatives
The sentences above follow the structure 'condition → result'. However, we can also use conditionals to give commands, requests, and advice.
- If you don't understand something, ask the teacher.
- If you hate someone, don't talk to them.
