Task 2. Read the text and use the given information in the story to answer the questions below. How I spent my summer vacation.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.
