Q: M: No. Why do you ask? W: You have so many empty cans here. M: Well, my mum wants me to keep all the cans, so that we can sell them after a while. W: Aha, you are going to make a millionaire of yourself sooner or later with all those cans. M: You bet I will. Well, that's not the point. The point is we separate reusable things from other rubbish. We have to pay the dustman for dealing with rubbish, but if we sell him these cans and other reusable material we pay less. W: That sounds a clever idea. Now what are reused in China? M: Metal, plastic, paper, books and the like. W: Just as we do back home in the States. M: And to avoid waste, the government is limiting the production of goods that can be used only once, such as bamboo chopsticks. For example, all the fast food boxes should be made of paper instead of non-reusable material. W: That will surely be helpful for a clean environment. What was said before this conversation?
A: W: Do you collect cola cans, Steve?

Q: W: Oh, very friendly and open-minded. Don't worry. I'm sure he'll let you give a performance there. The good thing is that a lot of famous people go there. So do reporters and photographers. M: Yeah, but what if he doesn't like our music? W: He'll like it. He hasn't had a live band for a while, so I think he'd like one for a change. What was said before this conversation?
A: M: So. What's your uncle like?

Q: W: You don't want to get one of those 3D TVs, do you? M: Well, I'm not sure. All I know is that I want something with a big screen,and the most important thing is a clear picture. W: Oh, you mean like the one our neighbor bought the other day? M: Yeah. They have fantastic sound, too. W: This all sounds a little expensive to me. I'm not sure if we have the money, even if we didn't go on vacation. M: Hey, look at this ad in the paper! They're having a special sale on TVs. This one is only $300! And even the biggest ones are only $500. W: Well, I think we can afford that. Let's go check out that sale! What was said before this conversation?
A: M: That's it! I've had it with this TV! We need to get a new one. The signal is so bad. It's ridiculous. All of our friends have nice TVs. It's high time we joined them.

Q: W: Alice. She said you were going to take them back to the library. M: Oh, that's right. She did ask me to take some magazines back for her. I completely forgot. What was said before this conversation?
A:
M: Who put this pile of magazines in my office?
