First Conditional + future time clauses

Syllabus topic 16: First Conditional + future time clauses

First Conditional + future time clauses. Use a present form in if and future time clauses, with a future/modal form in the main clause.

How it works

Use a present form in if and future time clauses, with a future/modal form in the main clause. Unless means if not. A present perfect time clause can emphasise completion before the next event.

Examples in context

Notice how each form fits its sentence. Read the context before choosing a form.

  • If you study, you will improve.
  • I'll wait until she arrives.
  • Unless it rains, we will eat outside.
  • Call me as soon as you know the result.
  • When I've finished, I will help you.
