Dear Kevin.
Thank you for your letter. In your letter you wrote about your favourite season.
Well, I want to tell you about my favourite season. There are four seasons in a year. They are winter, spring, summer and autumn.
I like summer best of all. There are three months. The weather is hot.
The trees are green. The days are long.
You can swim. I like summer very much.
I must go to help my grandmother in the garden.
Yours, (cвое имя)
