First Conditional Exercises

The first conditional describes real possibilities in the future — situations that can actually happen if a condition is met. Unlike the zero conditional (which describes general facts that are always true), the first conditional talks about specific future events that we believe are possible or likely. It is one of the most common conditional forms in everyday English, used for plans, promises, warnings, threats, and predictions.

The basic structure is: the if clause uses the present simple, and the result clause uses will + base verb. However, native speakers frequently use other modal verbs in the result clause — can, may, might, should — to express different levels of certainty. You can also use going to for intentions or imperatives for direct instructions: "If you see John, tell him I called." The if clause can come first or second in the sentence. When it comes first, add a comma. When it comes second, no comma is needed.
