Tom was seven years old, and he was going to school soon. He was a good boy, but he didn’t like to get up early. He slept until nine or ten o’clock in the morning.
His mother didn’t want Tom to be late for school. So she bought him an alarm clock. She said to Tom, “You must get up when you hear the clock ring.” After that, Tom got up when he heard the clock ring at six thirty every morning.
One day, the clock didn’t work. Tom didn’t get up at six thirty. It was time for her to wake him up. Tom said to his mother, “I woke up very early.” “Then why didn’t you get up?” Mother was angry. “You told me that I must get up when I heard the clock ring. So I’m still waiting for the bell".
Mẹ Tom mua cho cậu một cái đồng hồ báo thức và bảo cậu phải thức dậy khi nào nghe tiếng đồng hồ reng, và cậu nghe theo. Nhưng có một hôm đã đến giờ ăn sáng rồi mà Tom còn chưa thức dậy. Mẹ hỏi cậu tại sao không thức dậy thì cậu nói: “Tại vì chuông đồng hồ không reng!”
