💡 Key points from the stream
- After would, use the bare infinitive: I wouldn’t go, never I wouldn’t goes (14:16).
- In If I were you…, use were with I. It’s a very common way to give advice (14:16).
- Contractions: they’d = they would, hadn’t = had not (5:38, 20:16).
- Second conditional = unlikely or hypothetical situations (5:38, 9:43).
- First conditional: if + present simple, then will (17:04).
- Third conditional = something that didn’t happen in the past, so it’s impossible now (20:16).
- Mixed conditional links an imaginary past with the present (42:51).

🎤 Activity 5: Speak, write and comment
Speaking (15 seconds to prepare, 45 seconds to speak): Talk about something you would change in your life if you could, and about one decision in the past that you would make differently. Use at least one second and one third conditional.
Show a model answer
If I could change one thing, I’d spend less time on my phone. If I had more free time, I’d read more books and go out for walks. About the past, if I had started learning English earlier, I would have found my job much more easily. But I’m happy now, because if I hadn’t made those mistakes, I wouldn’t have learned so much from them.
Writing (aim for 150 to 250 words): Write an email to a friend about a day that could have gone differently. Use first, second and third conditionals.
