Hello, (имя кому пишешь)
Your last letter was a real surprise. I'm sorry I haven't answered earlier but I was really busy with my school.
It is fantastic if you are going to do this project. I think It will be very interesting and you will learn a lot of new. If I were you, I would write about Pink Sea (Hillier) in Australia. This place is amazing. And I want to visit Australia somewhen to see this sea.
You should find some information about it and I hope that you will get the highest mark! Well, I’d better go now as I have to do my homework.
Yours,
