Could you please help with conditionals usage?
I'm practising those right now, but do I understand everything correctly?
If I see water, I drink it
// Every time I see water, I drink it
If I see water, I will drink it
// It's something probable. For example, I'm on the street looking for a drinking fountain
If I saw water, I would drink it
// I'm thirsty in the middle of the desert. There's still a tiny possibility of finding an oasis
If I had seen water, I would have drunk it
// Now I'm at home, recalling my desert adventure, where I didn't find any water
Am I right in every case? Does it sound natural and formal enough? (I'm preparing for IELTS)
