The zero conditional expresses unreal hypothetical situations and uses the future tense in the main clause to indicate a highly unlikely consequence.

The second conditional uses would + base form in the conditional clause and simple past in the main clause, since it represents a realistic sequence in the future.

All three conditionals use the simple present in the conditional clause, varying only the type of modal used in the main clause.

The zero conditional and the first conditional share the same semantic meaning, as both refer to habits and routines without any expression of futurity.

The first conditional uses the present tense in the conditional clause and the future tense in the main clause, indicating a realistic and possible event based on temporal projection rather than on a counterfactual hypothesis.
