i think summer is the best season for rest because it is warm, the nature is beautiful and we have great opportunities for rest. summer is a time of holidays. we can go for a walk all day long, watch the clouds, swim, sit down by a river or a lake on fresh, green grass,

climb high hills, play different games, ride a bicycle and so on.

i spend my summer holidays at my granny. there were many things there to enjoy. i swam in the sea, lay in the sun and did many other things. sometimes i made a fire with my friends at the seaside and cooked potatoes there. it was wonderful. we told anecdotes to

each other, and did everything we wanted. i also got used to walk alone in the forest.

when the august was coming to the end, i went on a small voyage by ship.

but the last summer wasn't for me only sugar and honey. i have passed through the graduating exams in school and entering exams in the university and technical university. so the bigger part of my summer vocations i spent at the books. of course, it was not

interesting, but i'm glad that i did it because now i'm a student of the best university in primorye and the whole far-east.
