A、By a hill. B、A concert. C、The waterfall scenery. D、A hotel they once stayed in. D本题问“根据对话内容，他们要去哪直度周末”。如文中反复提到的“Watermill Inn”

W: What are the flowers for, Richard?
M: Five years of happiness. Happy anniversary.
W: But our anniversary isn’t until Saturday.
M: I couldn’t wait. Besides, we are not going to be here Saturday.
W: Where are we going to be?
M: If you had your choice of all the places in the world, where would you choose to spend our anniversary?
W: The Watermill Inn. I loved that place when we went on our honeymoon.
M: Perfect! You picked the right place.
W: I don’t understand.
M: You and I are going to spend a second honeymoon at the Watermill Inn.
W: Oh, Richard! That’s wonderful, but...
M: No buts, absolutely not. The world’s greatest grandmother, Mrs. Ellen Stewart, has agreed to take care of him for the weekend.
W: But isn’t that too much to ask of your mother?
M: Too much? She loves taking care of Max.
W: But... I’ll miss him.
M: Well, we’ll phone every hour, and you can listen to him over the phone. Come on. Honey, it’s time you and I had a romantic weekend alone together. We’ve earned it. What do you say?
W: It does sound tempting. You’re right. We’ve earned it.
M: Great! I’ll make a reservation fight now. Remember that wonderful little balcony where we had our meals... with a view of the Hudson River?
W: How could I forget?
M: My mom is available to baby-sit this weekend.
W: Well, OK. Check if they have a room.
M: I’ve already made arrangements. Right! You and I are going to have a wonderful, romantic weekend!
