After the history class,Li Ming sits in the classroom，deep in thought. Wang Mei comes in and the two start a dialogue.
Wang Mei: Hi Li Ming. What are you thinking about?
Li Ming: Oh, hi Wang Mei. I was just thinking…What is the meaning of life?Do you ever wonder about that?
Wang Mei: Oh, I see. You are thinking about your purpose in life. Yes,I think about that sometimes. But I also wonder about other things. For example，why are great people so successful?And how can we succeed in life?
Li Ming: Those are good questions, too. But…what is success? And how do you know if you've succeeded?Does it mean that you have a good job? Does it mean that you are rich and famous?
Wang Mei: Those are all really important questions and very difficult to answer. I'm not sure how to answer them, but I think we should try our best to live a good and happy life.
Li Ming: That sounds right to me. My dad always says that we should be good to others.
Wang Mei: Exactly! If we are living a happy life, but the people around us aren't, is that a good life?I'm not so sure…It seems like something is missing.
Li Ming: I agree. I have an idea, Wang Mei. Let's write these questions down and then survey our parents, friends and neighbours about their thoughts.
Wang Mei: Great idea, Li Ming! Let's do it!
