Conditionals type 1 or first conditionals are used to describe future events that will happen or are likely to happen. These sentences are based on facts, thus we make statements about the real world or particular situation.
If you don't study, you will fail the exam. (Sometimes you can pass an exam without studying, but this time it won't work)
Use the present simple tense in the if clause and the future simple tense in the main clause. Note that the order of the main and if clauses is not fixed. Although when the if clause precedes the main one, use a comma.
| IF clause (If + present simple) | MAIN clause (future simple) |
|---|---|
| If the weather is great, | we'll go to the park |
| If you don't stop fighting with each other | you two will be grounded! |
Note that it is possible to use other present tenses (e.g. present continuous, present perfect) in the if clause.
If you're going, I'll go too! (if + present continuous, future simple)
If they've already received you information, they will let you know. (if + present perfect, future simple)
First conditionals can be used to give instructions in some particular situation.
If you carry all these bottles at once, you'll drop them. It's too dangerous!
Use the present simple tense in the if clause and the future simple tense in the main clause.
if - anyone - to break in - the police - to be - here - in 5 minutes.
I - to stop by - if - I - to get off from work - earlier - today.
