How I spent my summer holidays.
My summer vacations this year were interesting and memorable. Every day was
filled with events.
In June, together with classmates, we went to a camp. I liked the camp very much
We played sports games, competed in various sports, took part in various
competitions. In the evenings, we went to the disco. I enjoyed discos as I like music
and dancing. I made a lot of new friends and got to know my classmates better than
at school
When I returned home after the camp, together with my parents we went to the
Crimea to have a rest by the sea. We stayed in a nice hotel in Feodosia. I really liked
the stony beaches, blue sea, and numerous excursions. Mom and Dad allowed me
to scuba dive and I saw the life of the seabed. I also visited the water park, made
trips on a motor ship, and rode horses. My rest by the sea was unforgettable.
In August, I went to the country to visit my grandparents. I have many friends in the
village where my grandparents live and we spent time together. We went swimming
and fishing
My summer holidays fly surprisingly fast. Now the school year has just begun, but
I'm already waiting for new vacations, new impressions and new friends.
