I’d like to describe picture №1. The picture shows some little girl. She is in her classroom. The girl is sitting at the desk. I think she is doing some task that her teacher gave to her. She is writing or drawing.  This little girl is very cute and smiley. She is the pupil, because she is wearing some school uniform. She's got fair hair in the ponytail. I like this picture and I've chosen it, because this girl is very nice and she's in a good mood doing her classwork.

Объяснение:

I like a lot of sports games but my favourite one is volleyball. I enjoy watching volleyball competitions on TV and I love playing this game!
I play it at school at my PE lessons and after school with my friends on the sport ground. Volleyball is a team sport in which two teams of six players are separated by a net. This game is very easy to play and is equally fun and enjoyable. It is interesting to watch volleyball matches on TV When high class teams is playing. I Would like to be a good volleyball player and take part in competitions.
