Mr Dan has an office. He works in the office from Monday to Friday. Every morning he has breakfast with his family at 7:30. He will read a newspaper, drink a cup of hot tea. Then he will leave his house at 8:00 to take a bus to work.
One morning he is still siting at the breakfast table and reading a newspaper at 8:05. He is not in a hurry (赶时间) and even asks for another cup of tea.
"Another cup of tea?" his wife asks. "Do you need to go to the office today?
"The office?" Me Dan says. "Oh, I think I'm in the office now. I should go now. I must take a taxi today or (否则) I will be late!"
