A well-structured letter is essential for clarity and coherence. Follow this format:

Sample Band 9 Informal Letter

Task:

You have recently moved to a new city and want to invite your friend to visit. Write a letter to your friend. In your letter:

  • Describe your new home.

  • Explain what they can do in your city.

  • Suggest when they should come and visit.

Hey Sarah,

Hope you’re doing great! It’s been way too long since we last met, and I really miss spending time with you. We need to catch up properly!

I recently moved to San Diego, and I have to say, it’s absolutely incredible! My apartment is super cozy, and the best part? It has a balcony with a breathtaking view of the beach. The sunsets here are stunning—you’d love them! The weather is perfect almost every day, with a cool ocean breeze and endless sunshine.

There’s so much to do here! We could spend the mornings at the beach, check out some amazing cafés in the afternoon, and even go hiking at Torrey Pines. Plus, the food scene is incredible—there are so many taco spots that I know you’d go crazy for!

You should definitely come visit next month! The weather will be ideal, and we’ll have an amazing time exploring the city together. Let me know what you think—I’d love to plan something fun!

Can’t wait to see you!

Take care,
Emma
