First Conditional – talking about real future situations

Structure

If-clause

Main clause

If + Present Simple

will + base verb

Example:
If I finish my work early, I will watch a movie.

Use the present tense after if, and will + verb for the result.

Examples

  • If it rains tomorrow, we will stay at home.

  • If she studies hard, she will pass the exam.

  • If I see Ben, I will tell him the news.

  • If they don’t hurry, they will miss the train.

  • If we go to the park, we will have a picnic.

Negative Form

Add not after will or in the if part:

  • If I don’t wake up early, I won’t catch the bus.

  • If it doesn’t stop snowing, we won’t go out.

Question Form

We can ask questions in two ways:

  • If you are tired, will you go to work tomorrow?

  • Will you call me if you need help?

No comma is used when the if-clause comes last.

Use the First Conditional to talk about real future possibilities.
It connects a condition in the present with a result in the future.
