in the country and a large garden around it.There are lots of beautiful
flowers in the gargen.Masha and her Mum take care of them and the
flowers grow very well.
Sekond, Masha is keen on collecting
stamps.She's got a wonderful collection of stamps about animals and
flowers. It's interesting to look through her albums of colourful
stamps.
Third, Masha enjoys going to the theatre. She is a real
theatre-goer! Masha's parents take her to the theatre twice a month. She
likes different plays: comedies and dramas, operas and ballets.
But
that's not all. Besides, Masha is very good at sports. She likes going
in for sports because it makes her strong and healthy. She is interested
in figure skating and tennis. But they take a lot of her time.
