Помогите срочно по английскому срочно!!!!
A You've received a letter from an old friend who lives very far away from you. a) Read the letter.

Flat 45,177 Kirov St
248000 Kaluga
5 August

Dear...,

How are you getting on? I haven't heard from you for ages. Where have you been?
I'm fine. At the moment I'm at home. I need some rest after my summer adventures. They were very exciting.
In June we went camping in the forest in Karelia. Fortunately the weather was great. There are a lot of beautiful lakes there too. Next year we'll probably go there again. Do you want to come with us?
In July I went to see my granny. She lives in a nice little village near Kaluga. My friends and I had a lot of fun. Unfortunately, their life isn't easy. A lot of people in the village have lost their jobs and they don't have much money.
I'm spending August at home because I have to get ready for school. This year is going to be very important for me. The good news is that Helen, who is good at all school subjects, promised to help me. Do you remember her?
I miss you a lot. How are you? How's your little brother? Say hello to your mum and dad too. I hope they're fine.

Write soon!

Вest wishes,
Your friend
