Susan: Can’t you come in and have tea now, Peter?
Peter: Not yet, dear. I must water the garden first.
Susan: Do you have to water it now?
Peter: I’m afraid I must. Look at it! It’s terribly dry.
Susan: What a nuisance!（真讨厌）
Peter: Last summer it was very dry, too. Don’t you remember? I had to water it every day.
Susan: Well, I’ll have tea by myself.
Susan: That was quick! Have you finished already?
Peter: Yes, dear. Look out of the window.
Susan: Good heaven! It’s raining. That means you needn’t water the garden.
Peter: That was a pleasant surprise. It means I can have tea, instead.
