Summer is my favorite time of the year. Summer holidays are the longest. This year I spent my summer holidays in the country. Most of the time I walked, cycled, spent time with my friends. When the weather was hot, we went to the river. In the evenings, I helped my mother water the beds in the garden. I liked my summer holidays very much.
