Lisa: Background music? Oh, like the music they're playing here now.

Howard: Yes. You hear it everywhere — in restaurants, airports, supermarkets...

Lisa: In banks too. I noticed it while at the bank today.

Howard: You're not supposed to notice it. (8[D]) It's just in the background. It' supposed to put you in the right mood.

Lisa: I'm not sure I like that idea.

Factories use it a lot.It makes the workers happy, and they work better that way. In one factory, music increased roduction 4.5 percent.

Lisa: I still think there's something about it that I don't quite like.

Howard: I know what you mean, but lots of people would not agree with you.

B．a music fan

C．a sales manager in a music company
