Dear Ann,
I was very glad to hear from you. I haven't written for ages because of my school activities.
Now I want to tell you about my summer holidays. When my holidays came I was very happy! The weather was fine so my friends and I went for a walk every day. It was fun! Then I spent a month in the country where my grandfather and grandmother lived. It was great. I drank milk and ate 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 played football and tennis every day! There is a small river near the forest and we swam when the weather was fine. It was great! I liked my holidays very much.
That's enough for me today. I have to go now.
Best regards to your family.
Write soon.

Yours Anita

Дорогая Анна,
Я очень рада получить весточку от тебя. Я не писала долго, потому что была занята своими школьными делами.
Теперь я хочу рассказать тебе о моих летних каникулах. Когда наступили каникулы, я была очень счастлива! Погода была хорошая, так что мои друзья и я ходили гулять каждый день. Это было весело! Затем я провела месяц в деревне, где живут мои дедушка и бабушка . Это было здорово. Я пила молоко и ела много вкусной пищи, которую моя бабушка готовила для меня. У меня много друзей в этой деревне, потому что я езжу туда каждые каникулы. Мы даже играли в футбол и теннис! Около леса есть небольшая речка. Мы купались, когда погода была хорошая. Это было здорово! Мне очень понравились мои каникулы.
Думаю достаточно на сегодня. Я должна идти.
С наилучшими пожеланиями твоей семье.
Пиши быстрее.
Твоя Анита.
