i spent my holidays very well. at the beginning of june i passed all my examinations with excellent marks and my parents gave me a present. this present was a new powerful computer! but i did not only stay at home. i went for a walk with my friends, rode by bicycle. it is so interesting to visit new places in the city, by riding bicycle. my native city is novosibirsk. i explored a lot of beautiful places, such as parks, monuments, fountains and other sightseeings. my favourite monument is a statue for visotskiy. i think, visotskiy is one of the greatest russian poets and bards. 

in july i went to a tourist camp for children timurovets. i met many new friends there. we played many exciting games, sang different songs and took part in different competitions. it was very sad to leave the camp, but i didn’t feel bored at home.  i went to the river with my father. we swam, sunbathed and hunted for lizards there. i got a lot of energy by having a rest and i could do boring work. for example, read school literature and do other homework and hometasks. i studied radio electronics and programming. it was very interesting for me, and so i made my first robot-hedgehog. it is a very nice hedgehog. 

maybe, my summer holidays weren’t very unusual, but i will remember them and look forward to the next ones.
