I think summer is the best season of all, because it is warm, the nature is beautiful and we have great opportunities for rest. Summer is a time of holidays. I spend my summer holidays at my granny's. There are many things there to do. What did most of the time. I swam in the sea and sunbathed. Sometimes i made a fair with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other,and did everything we wanted. It was delicious and i really miss this holidays.

Я думаю,лето -самое лучшее время года ,потому что тепло, вокруг очень красиво и у нас есть чудесная возможность отдохнуть. Лето-время отпусков и каникул.Я провёл летние каникулы у моей бабули. Там есть чем заняться . Большую часть времени я плавал и загорал. Иногда я разжигал с друзьями костёр на берегу и мы пекли в нём картошку . Это было замечательно. мы рассказывали друг другу анекдоты и делали всё что хотели. Это было замечательно и я очень скучаю по этим каникулам.

I would like to tell you about Steven Hawking. He was born in England  8 01 1942. Both his parents had studied at Oxford. Both his parents had studied at Oxford. When he was 21, Stephen started tripping, dropping items and his speech became unclear. After a series of tests, doctors concluded that Stephen was suffering from ALS- Amyotrophic Lateral Sclerosis; a disease which paralyzed him and required a speech generating device to communicate. His most famous theory is that black holes can emit radiation; also known as Hawking radiation. Hawking has received numerous awards but never won the Nobel Prize. To my mind, it is so sad. I think, he made lots useful invention.
