if i would have chance to volunteer, i would like to volunteer in the country, which needs it the most. i i would like to go to africa. i want to help children and women- since they are the most vulnerable.

i am also interested in different cultures, and i would not experience it otherwise.  what could be more different, then africa?

i also understand, that besides helping others i would contribute to my career. i am thinking about medical field, and helping others will help me to see if i am strong enough to go this path. 

what could be better, then helping somebody, who needs it the most?

at last the winter holidays came! i was very happy!     i hadn't to get up early in the morning and run to school. i could stay in bed till midday. but i didn't want to sleep. there were a lot of things to do.

the weather was fine so my friends and i went to the skating- rink almost every day. it was fun!

then i spent a week in the country where my grandfather and grandmother lived. it was great. i drank milk and ate a lot of tasty food that my granny prepared for me.

i have many friends in this village because i go there every holidays.

we went to the forest to ski, we made snowmen and played snowballs. we even played hockey!

but the winter holidays were over and i returned to the city again.  i liked my holidays very much.

наконец наступили зимние каникулы! я был счастлив!   я не должен был вставать рано утром и бежать в школу. я мог оставаться в постели до полудня. но я не хотел спать. было так много дел.

погода была хорошая, так что мои друзья и я ходили на каток почти каждый день. это было весело!

затем я провел неделю в деревне, где   живут  мои дедушка и бабушка  . это было здорово. я пил молоко и ел много вкусной пищи, которую моя бабушка готовила для меня.

у меня много друзей в этой деревне, потому что я езжу туда каждые каникулы.

мы ходили в лес кататься на лыжах, мы делали снеговиков и играли в снежки. мы даже играли в хоккей!

но зимние каникулы закончились, и я вернулся в город снова. мне понравились мои каникулы.
