　　Conversation A

　　Constance is visiting her friend George at his apartment.

　　Constance: Wow! I see you've bought an aquarium. Nice!

　　George: You should get one too. I highly recommend it.

　　Constance: Why? What doesshavingsa bunch of fish do for you?

　　George: I find it relaxing to just sit and look at tropical fish at the end of a tiring day.

　　Conversation B

　　Constance: I can relate to that. I like to take it easy after work.

　　George: There's more to it than that. They're fascinating creatures. They provide me with hours of entertainment, believe me.

　　Constance: Perhaps I should give it a try.

　　George: If you really are interested in setting up an aquarium, I can lend you a couple of good reference books.

　　Constance: Great! Any other tips on getting started?
