It's Sunday today. The weather(天气) is fine. Tom doesn't need to go to school. He takes the No. 24 bus to Wanda Cinema(电影院). An old man gets on (上车) the bus at the Xihu Park Stop. Tom stands up (站起来) and says to the old man, "Come and sit here, please!" The old man goes over and sits down. He says, "Thank you very much, my boy. You are a good student." "You're welcome," says Tom.
"Which school are you in?" the old man asks Tom.
"I am in No.16 Middle School(中学)," answers (回答) Tom.
"No.16 Middle School? I graduated(毕业) from this school 50 years ago(以前)," says the old man.
"We are alumni," says Tom. Then they begin to talk about No.16 Middle School.
