Combining different time frames: past condition → present result or present condition → past result
Type 1: If + past perfect, would + base (present result). Type 2: If + past simple, would have + V3 (past result)
Add not to modal or auxiliary as needed
What would you be doing now if you had...? / What would have happened if you were...?
💡 Match the time of the result clause to the time you're talking about (now vs then).
✓If I had taken that job, I would be living in Paris now.
✗If I had taken that job, I would have been living in Paris now.
Past condition + present result uses would + base.
✓If he weren't so lazy, he would have finished by now.
✗If he hadn't been so lazy, he would have finished by now.
Present trait + past result uses past simple in if-clause.
✓If we had left earlier, we wouldn't be stuck in traffic.
✗If we left earlier, we wouldn't be stuck in traffic.
Past condition needs past perfect.
