Kathy is a 20-year-old girl. She is happy because she starts a new job at a radio station today. She takes bus No. 72 to work. The bus ride takes about 25 minutes. Kathy wants to get to her office (办公室) early this morning, so she can make a good impression (印象) on her new boss (老板).
The bus usually comes to the bus stop at 7: 10, but now it is 7: 15. The bus is late. Kathy must get to the radio station before 7: 50. She wants the bus to come in 5 minutes. If it doesn't, she will need to call her boss and tell him that she will be late. That will be too bad.
