Dear Li Hong,
I'm so glad that you will come to our school and I think it'll be great for us to live together for a week.
My home is not far away from our school. It's only three miles away. It's a little cottage. My favourite place in my home is the big yard. My parents grow many flowers in the yard to make it beautiful. I can enjoy a cup of tea in the yard at weekends.
We have three bedrooms in my home. So you can have a bedroom of your own. After school, we can water the flowers together. At weekends, we can have fun going fishing with my dad. Or we can have a BBQ with other classmates in the yard.
I hope we can have a great time together.
