СРОЧНО ПЕРЕВЕСТИ!!!!!!!2 Read the letter and say what sentences after it are true.
Dear Meg,
My family and I were at the sea in
July and we loved it there. Our hotel was big and very comfortable.
There were a lot of cosy cafés and
shops near it. There was a modern
cinema and a concert hall too. The
hotel had a good swimming pool and
I often went there. The room had a television, a fridge
and a shower. The hotel was near the sea in a very beautiful place. The weather in July was wonderful, hot and
sunny. We had a very good time and met some very pleasant people. The children enjoyed it a lot. They say they
had the best holidays ever.
Now we are at home and there are a lot of things to do.
School begins next week. My work begins next week too.
We are going to visit my parents at the weekend, clean
the house and water the garden. Come and see us soon.
Martin

We spent two weeks in scotland tat summer school. Would you like to know what we did there? Well, in the morning we spent 3 hours learn English.
