В каждом предложение нужно написать какое время используется!
After my hard and busy school year my summer holidays began. I felt happy when hard and busy school year finished and summer holidays began. I started to plan a lot of wonderful things to do during my summer vocation.

I was dreaming about visiting far south countries I always wanted to visit. For example, I dreamed to visit, Greece islands or Spanish beaches. But I had to go to the Azov Sea seaside with my parents. The water was very warm there, because the Sea of Azov isn't deep. There were different kinds of entertainments there. Best of all I liked water scooters and discos.

There was nothing to do all day except taking sunbathes and swimming. I was playing with my little sister on the sand and taught her to swim. Later, I returned home and spent some time there going out with my friends, reading, listening to the music, watching TV and playing computer games. After that I went to the sport camp where I spent twenty days with my friends.

It was very useful experience for us, because we had to get up very early, to train a lot. But it made us stronger and healthier.

I was very happy to return home and to spend several days in my summer cottage, where I had a rest helping my grandfather to dig the garden, to irrigate plants and to gather fruit and vegetables. I was fishing with my grandfather sometimes and we cooked our fish together.

Only insects were spoiling my good humour. I was enjoying floating in the boat, swimming and helping my grandparents.

During my summer holidays I made new friends, read a lot of interesting books, knew many useful things. Now, I feel ready to get back to school.

I am happy to meet my school friends and teachers.
