Humorous stories or fables about 5 minutes before the third class of CET-4.

A mother and her little son got on a bus. The bus conductor asked them for money. Mother said, "I want to buy a ticket to Shanghai" and gave her 5 yuan money. The conductor looked at the boy and said to him, "How old are you, young man?" Mother began to talk, but the conductor stopped. The boy said, "I was 4 years old at home and 2 years old on the bus." Mother wants to give it to 2.5 yuan, the conductor. A mother and her son got on a bus. The conductor came up to them and asked them to buy tickets. Mother said, "I want a ticket to Shanghai." Then he gave the conductor 5 yuan money. The conductor looked at the boy and said to him, "Young man, how old are you?" Mother was about to speak when the conductor interrupted her. Then the boy said, "I am 4 years old at home and 2 years old in the car." Mother had to give it to the conductor 2.5 yuan again. This is a little joke.
