Learning objective

By the end of the lesson, students will be able to form and use the third conditional to discuss past unreal situations and their hypothetical outcomes. Students will practise reading, speaking and writing skills.

Adapt the timing, prompts and amount of written work to suit your class size and proficiency level.

2

Grammar focus

The structure and meaning of the third conditional.

If-clause If + past perfect (had + past participle)
Result clause would have + past participle

Reading handout

Missed Opportunity — B2 reading and discussion.

Missed Opportunity

Imagine you had gone to that art exhibition last month. You would have been amazed by the intricate paintings and sculptures on display. The event took place in a renowned gallery, and art enthusiasts from around the world attended. If you had taken the chance to attend, your perspective on contemporary art might have broadened.

Unfortunately, you didn’t hear about the exhibition in time. If you had seen the announcement earlier, you would have marked the date on your calendar. You could have spent hours admiring the creativity of the artists and interacting with fellow art lovers. What a missed opportunity it was!

If you had known about the exhibition, you might have invited your friends to join you. It could have been a memorable outing, full of discussions about each artwork’s meaning and inspiration. You would have cherished the experience and shared it with others.

Reflecting on it now, you realise how different things would have been if you had been there. The event was a unique opportunity to connect with the art world, and you regret not attending.

Role-play scenarios

Six situations for practising hypothetical past conversations.

1. The Missed Flight
  • Alex — passenger
  • Sarah — airport employee

Alex missed a flight to an important business meeting and asks what could have been done differently and whether another option is available.

Alex: Excuse me, I missed my flight to New York. If I had woken up earlier, I would have been on time. Is there another flight today?

Sarah: I’m sorry, but the last flight has already departed. If you had arrived earlier, you could have caught it.

2. The Forgotten Anniversary
  • Lisa — wife
  • Tom — husband

Tom forgot their wedding anniversary. He apologises and explains what he wishes he had done differently.

Tom: Lisa, I’m really sorry I forgot our anniversary. If I had marked it on the calendar, I would have remembered. Can we still celebrate?

Lisa: It’s not the same now, but I appreciate the apology.

3. The Lost Wallet
  • Emily — wallet owner
  • John — person who found it

John returns Emily’s lost wallet. They discuss what might have happened if nobody had found it.

Emily: Thank you so much for finding my wallet. If you hadn’t found it, I would have been in big trouble.

John: It’s lucky I spotted it. If I hadn’t, you might have lost all your important cards and money.

4. The Broken Promise
  • Mike — friend
  • Sarah — friend

Mike promised to help Sarah move but did not arrive. They discuss how the day could have been different.

Sarah: If you had kept your promise, we would have finished much faster.

Mike: I know. If I hadn’t overslept, I would have been there on time.

5. The Lost Ticket
  • Emily — concertgoer
  • Ticket salesperson

Emily has lost her concert ticket and asks whether there is still a way to enter the venue.

Emily: If I hadn’t been so careless, I would have the ticket with me. Is there anything I can do?

Salesperson: Without your ticket, we can’t let you in. If you had kept it safe, you could have enjoyed the concert.

6. The Missed Bus
  • Mark — passenger
  • Bus driver

Mark missed a bus to an important meeting and asks the driver for advice.

Mark: If I hadn’t hit snooze on my alarm, I would have been on time. Can you help me?

Driver: If you had arrived earlier, you would have caught it. Maybe you can take a taxi.
