Ответ:

Dear Sally,

Greetings from [название вашего города по-английски]! How are you?

I'm in USA.

The weather is nice.

Our hotel is old.

I swim everyday.

Right now I'm watching TV. Mum is watching TV with me.

We plan to go to the park.

People celebrate Christmas.

See you soon.

Best wishes,

[Ваше имя].
