The only sound that you can hear in Kate's small room is the clicking of a computer keyboard, Her mum does no longer know what to do. Every day, it's the same, Kate does no longer pay attention to her studies or to the report she has to present next week She ignores all types of homework. Her mother says: "She cares only about the conversations she carries on with people from all over the world without caring about her grades or her friends in real life" The Internet access in American households increases, that's why the number of teenagers who spend a long time of their lives online, has increased too. Psychologists say: "Look out! An increasing number of teens is going into a new form of addiction. In an interview Kate declared: "I'm destroying my future and I am becoming isolated from the society," "I failed English last year... I didn't care about my studies but at least. I feel free. In fact, I can talk to others about any topic without being afraid of the consequences". 1) How does Kate do her home task every day? 2) What does she think about in mother's opinion? 3) What is a new form of addiction? 4) Does Kate have a progress in her study? 5) What is the main thing for Kate?​
