Поставь существительные во множественное число the millers have got three

I'd like to describe picture number 1. The photo was taken inside. The picture shows us the boy using computer. The action is taking place in a computer club or in a computer class at the school. Looking at this picture I get the impression that boy completing a hard test or playing in a difficult game. He looks very serious and focused and he's concentrated on monitor in front of him. He wear a shirt and he looks like he's about 13 years old. I like this photo because I like to play and work on computer too.
