Summer for me was not rich in adventure and travel. I stayed in the city with my parents. While my parents went to work, I helped them around the house: I washed dishes, cleaned them, and even sometimes cooked lunch.
 

Over the summer I read a lot, I also watched cognitive programs on TV about animals. In the middle of summer my parents took a vacation, and we spent more time together now. In the evenings, they often played board games, watched comedies and went for walks.
Перевод:
Лето для меня не было богато на приключения и путешествия. Я остался в городе со своими родителями. Пока родители ходили на работу, я им по дому: мыл посуду, убирал и даже иногда готовил обед.

За лето я много прочитал, еще я смотрел познавательные передачи по телевизору про животных. В середине лета мои родители взяли отпуск, и мы проводили теперь больше времени вместе. По вечерам часто играли в настольные игры, смотрели комедии и ходили гулять.
