last summer i went to the black sea with my parents. we  stayed there for a fortnight. i went swimming every day. the weather was wonderful all the time, the water was warm and clean. we bathed and watched small fishes and jelly fish in the water. sometimes we saw sea stars or sea shells there. once we even saw a dolphin. we often sat on the beach and watched  ships sailing in the  distance or looked at numerous seagulls gliding over the sea. we ate ice-cream and fruit on the beach and lay in the sun. i had a nice tan by the end of our rest. i made a lot of friends and we played volleyball on the beach.   every morning we had nice breakfast and a small run along the coast. 

my days were full of different events and on coming back home in the evening i was exhausted but slept with a smile on my face. 

in a word, i had a wonderful time, and unforgettable experiences. next year i will certainly go to the seaside again.

прошлым летом я ездил на черное море с моими родителями. мы были там  две недели. я ходил каждый день плавать. погода была замечательная все время, вода была теплой и голубой. мы купались и смотрели рыбок и медуз в воде. иногда мы видели морских звезд или морских ракушек. однажды мы даже видели дельфина. мы часто сидели на пляже и смотрели, как корабли плывут в отдалении и смотрели на многочисленных чаек, скользящих над морем. мы ели мороженое и фрукты на пляже и загорали. у меня был красивый загар к концу нашего отдыха. я нашёл там много друзей и мы играли в волейбол на пляже. каждое утро мы завтракали и совершали маленький пробег вдоль побережья.  мои дни были полны разных событий и возвращаясь вечером домой, я был усталым, но спал с улыбкой на лице.  одним словом, у меня было там прекрасное время и я получил незабываемые впечатления. в следующем году я обязательно поеду снова к морю.
