Real-World Examples

Research Grant Proposal

Strategic Business Plan

If we had invested in digital transformation earlier, we would be better positioned for current market demands.

Personal Development Reflection

🎯 ASTUCE RAPIDE

Conditionnels : SI + RÉSULTAT logique ! First : 'If I study, I will pass' (réel) → Second : 'If I studied, I would pass' (hypothétique) → Third : 'If I had studied, I would have passed' (irréel passé). Hiérarchie conditionnelle !

**First Conditionnel ** IF + Present Simple, WILL + base verb - situations réelles probables : "If it rains, we WILL stay home" !

**Second Conditionnel ** IF + Past Simple, WOULD + base verb - situations hypothétiques imaginaires : "If I HAD money, I WOULD travel" !
