Model Answer 1 – Music Festival

Exam Task (Shortened)

You went to a music festival. Describe it, explain what you did, and invite your friend next time.

Subject: You won’t believe this festival!

Hi John,

How are you? I’ve just got back from the most amazing music festival and I had to tell you about it.

The whole place was vibrant from the moment we arrived. There were live bands on different stages, food stalls from all over the world, and even a quiet picnic area where people could relax. My friends and I spent the day dancing, trying new dishes, and chatting with other festival-goers.

The highlight was when my favourite band finally came on stage — honestly, it felt unreal! I’m still smiling when I think about it.

You should definitely come with us next year. I’m sure you’d love it just as much as we did. Let me know what you think!

Take care,

Alex

Model Answer 2 – Camping Trip Invitation

Exam Task (Shortened)

Invite your friend on a camping trip. Give details and explain why it will be fun.

Subject: Fancy a weekend in nature?

Hi Jamie,

Hope you’re doing well! I’m organising a camping trip to Maplewood National Park next month, and I’d really love you to join us.

We’re leaving early on Saturday morning and coming back on Sunday evening. I’ve already booked a campsite by the lake, so we can go hiking, try canoeing, and maybe even have a barbecue in the evening. To be honest, I can’t wait to escape the city for a while.

Knowing how much you enjoy outdoor adventures, I’m sure you’d have a great time. Are you free that weekend? Tell me if you’re in!

Cheers,

Sam

Model Answer 3 – Charity Run

Exam Task (Shortened)

Describe a charity run, explain how you felt, and invite your friend next time.

Dear Sarah,

How are you? I wanted to tell you about the charity run I took part in last weekend.

It was held in a beautiful park to raise money for a local animal rescue centre. The atmosphere was fantastic, and everyone was really supportive. At one point I even tripped over my shoelaces — don’t worry, my pride suffered more than my knees!

Although I was exhausted by the end, I felt incredibly proud to have done something meaningful. It was definitely worth the effort.

There’s another run next month, and I think you’d really enjoy it. It would be great to do it together. Let me know what you think!

Best wishes,

Emily
