Lesson 14
Jack like studying history very much.  One Sunday morning, he was planning to  visit  a museum. He hurried to the station to catch the 7:30 train. As soon as he got there, he tried to buy a ticket for that train. The ticket  clerk said," The 7:30 train has just left. The next train will leave in 30 minutes."
"Has the 7:30 train gone already? It 's  7:27 by my watch. "said jack.
The clerk said with a smile," Look at that clock on the wall. It's already passed 7:30. Your watch is 3 minutes slow."
