Jack is a twenty-year-old young man. Two years ago, when he finished middle school, he found work
in a shop. Usually he works until ten o'clock at night. He is very tired when he gets home. After a quick
supper he goes to bed and soon falls asleep. His grandma lives downstairs and she is satisfied (满意的)
with him.
     One day, on his way home, he met Mary. They were both happy. He asked the girl to his house, and
she agreed happily.   He  bought  some  fruit  and drinks for her.   And  they  talked   about their school,
teachers, classmates and their future. They talked for a long time.
     "Have a look at your watch, please," said the girl. "What time is it now?"
     "Sorry, something is wrong with my watch," said Jack. "Where's yours?"
     "I left it at home."
     Jack thought for a moment and found a way. He began to stamp his foot on the floor, "Bang! Bang!
Bang!"
     The sound woke his grandma up. The old woman shouted  downstairs,  "It's twelve o'clock  in  the
night, Jack. Why are you still jumping upstairs?"
