Michael is a nineteen-year—old young man. One year ago，when he finished middle school，he found work in a shop. Usually he works until ten o’clock in the evening. He is very tired when he gets home. After a quick supper he goes to bed and soon falls asleep. His grandma who lives downstairs is satisfied with him.
One day，on his way home，he met Lily. They hadn’t seen each other for a long time. 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 Michael，“Where’s yours?”
“I left it at home.”
Michael thought for a moment and found a way. He began to stamp (踩脚)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，Michael. Why are you still jumping upstairs?”
How old was Michael when he finished middle school?
