Нужно перевести текст в косвенную речь:

I live in the country and I go to the little village school.

We are all together - boys and girls of all ages.

We are one big happy family bacause wa all get on !

The teachers are very good and they make learning interesting and fun.

Besides, there are lots of after-school activities for children with different interests.

I play in the school band. Its very interesting ! I am glad that I go to my little village school.
