Modern means of communication are changing every time. They influence our life immensely. If many centuries ago people did not know about them, nowadays we cannot imagine our life without them. Among modern means of communication, my most favourite are a cell phone and the Internet. I talk to my family and friends on phone every day and it is very comfortable. As for the Internet, virtual communication makes it easier to make friends. But, of course, means of communication are very harmful for our health. People are so addicted to them that they don't pay attention to the risk. I think that modern means of communication are harmful but, if to use them carefully, you can possibly avoid it.

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 the bed till midday. But I didn't want to sleep. There were a lot of things to do.

The weather was fine so my freinds 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 eat a lot of tasty food which 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 play 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 очень 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 очень понравились мои каникулы.
