Please answer this: W: Yeah, I guess so. I spent the weekend at the beach. M: Oh, yeah, that's great. Where did you stay? W: Some friends of my parents' live out there and they invited me for as long as I wanted to stay. M: So what are you doing back here already? W: Oh, 1 have a paper to work on, and I just couldn't do any serious studying at the beach. M: I don't blame you. So what did you do out there? I mean besides lying out in the sun. W: I ran slowly up and down the beach, and 1 played some volleyball. You know I never realized how hard it is to run on sand. I couldn't even get through a whole game before I had to sit down. M: Did you go swimming? W: I wanted to, but they said the water isn't warm enough for that until a couple of months from now. M: It all sounds nice. I wish I could get away to the beach like that.

Answer: M: Hey, Karen, it looks like you've got some sun this weekend.
Problem: W: It's a good job that we got here early. Look at all those cars there. They'll never get in. M: You'd better follow me closely. I don't want to lose you. W: Don't worry. I'll keep up.

A: M: It's lucky that we rode our bike here instead of driving.
Problem: Given the question: W: Well, as a matter of fact, we were discussing this question last night. We all spoke of the Great Wall, one of the seven wonders of the world. We wouldn't want to leave China without seeing that. If it could possibly be arranged, how far is it from here? M: Only about 50 kilometers. Just an hour and a half's trip by car. We'll put down at the Great Wall then. W: Good! And we've heard quite a lot about the Summer Palace. We'd like to see that, too. M: All right, the Summer Palace, well, and there are a number of places that I think you'd find interesting, the Temple of Heaven, the Former Imperial Palaces and the Ming Tombs.
