M: Excuse me, Alice, I've never used this place before. Can you tell me how to use the machines? ,F: What do you mean? These are the washing machines. Those big things over there are the dryers. ,M: I see. Do the machines have soap in them? ,F: No, of course not. You have to put soap in. Did you bring your soap? ,M: No, I don't have soap. ,F: Well, you can buy some over there. ,M: Thanks. OK, I have my soap. ,F: My god, you really bought a lot. Why do you need so much? ,M: I don't know. I want my clothes to be clean. ,F: But you can't use so much. The machines won't be able to remove the soap completely. On the contrary, too many bubbles trapped dirt, allowing bacteria to build up. ,M: Oh, I guess I didn't know. I have never washed close before. ,F: What? Did you say you never wash clothes before? ,M: Yes, never. ,F: I can't believe it. How can that be? ,M: My mother always did it.
(A) F: I am excited, because I can be your teacher now. Remember what I said, put more soap. (B) F: Oh, darling, I feel so disappointed. Your grandma shouldn't have done so much washing for you. (C) F: I am really sorry, I did not catch that. Would you slow down, please? (D) F: I still can't imagine that. You never washed clothes before? Never?
