My summer was great! My friends bathed in the river, it was very cold. Sometimes went to fish. Once we caught grandpa big carp and broke the rod. It was very fun and exciting. My mom baked a wonderful summer pies with the apples that my neighbour collected in the garden. I look forward to next summer!
ПЕРЕВОД_
Моё лето отлично! Мы с друзьями купались в речке, она была очень холодная. Иногда ходили ловить рыбу. Однажды мы поймали с дедушкой большого карпа и поломали удилище. Было очень весело и увлекательно. Моя мама пекла всё лето замечательные пироги с яблоками, которые я с моим соседом собирали в саду. Я с нетерпением жду следующего лета!

Of all the seasons, most of all I like spring. Spring blooming most of the flowers. Welcome come warm weather, rain less, and they are getting warmer and warmer. Mom hides winter clothes in the closet, and my dad gets out of the box in the garage of tourist facilities. I am preparing my bike, because soon dry up puddles and you can drive around the yard, fun ringing unwary children. Wonderful time - spring! In the early spring, we give our mothers, grandmothers and sisters of flowers and gifts. March 8 - one of the most favorite people. And at the end of spring at another school holiday - last call. This is my favorite holiday because after the holidays begin.
