    There are many TV shows about young people and their problems. We ask two youngsters, Rita

and Meg, about their favorite series and its main character.

    Rita: I think that my favorite series at the moment is Get Real. It's about an American family with two

sons and a daughter. The daughter's name is Megan. I like her character very much. She is l7 years old.

She has got long, dark brown hair and dark brown eyes. She is quite hard-working but she doesn't have

plans to study at university. She hasn't got many friends because she is quite shy. I like the series because

it is about real problems in the life of young people. At first it looks like a comedy but then it changes into

a real drama.

main characters, a single mother and her daughter, a l 7-year-old girl called Rory. She is not very tall and

reads books and works very hard. She hasn't got many friends because she is now in a new school. Rory
