听力原文:M: Hello. Would you please tell me something about the stock?
W: Sure. What do you want me to start with?
M: Please start with the explanation of some terms like "a bull" and "a bear".

M: What about a bear then?
W: A bear is the situation in which share prices keep falling.
M: Oh, I see. But why the prices get rising or falling?
W: If there are more buyers, the price will rise. Otherwise, the price will be lower and lower.
