Mary is a secondary school student. She likes daydreaming in class. Once she was sitting at her maths lesson and thinking about summer. ' If it
summer now, I would be on the beach. If I was on the beach, I

a sandcastle. I would be very proud of myself if my friend Ann
it.' Suddenly she heard her teacher's voice asking a question. Mary had no idea what her teacher was talking about. She was really ashamed. 'I will stop daydreaming in class,' she thought. 'If I
daydream, I will be more attentive. If I am more attentive, I
my teacher's next question easily.'
