Zero Conditional, First Conditional and Second Conditional

1. Zero Conditional

   • We use the zero conditional to talk about things that are always or generally true.
     • If I drive into town, I pay for parking.
   • We use the simple present in both the if clause and the main clause.
     • If you drive on a highway, you don´t see any traffic lights.
   • We can use when instead of if in the if clause.
     • If people use public transportation, there is less traffic.

2. First Conditional

   • We use the first conditional to talk about something that is possible in the future.
     • If you go for a walk in the park, you will feel better.
   • We use the simple present in the if clause, and we use the future with will in the main clause.

   • We can use unless instead of if not in the if clause.

   • We can also use a modal verb (can, must, should, etc.) or the imperative instead of will in the main clause.
