F: Thanks a lot for coming again. ,M: Tell me what happened this time? Is it the keyboard again or the mouse? ,F: Well, the keyboard is ok now, and the mouse is working well, too, even though you suggested that I get a new one last time. Actually the problem is when I was working this morning, the screen suddenly went black. ,M: Ok, let me have a look. The screen seems to be working, so I'll take a look at the inside of the laptop. Did you save your files? ,F: No, since I didn't know that the computer would stop working. Please don't tell me I've lost my report. ,M: I'm afraid so, here's the problem. Something has overheated inside the laptop. ,F: Can you fix it quickly? ,M: I'll try. It may take a couple of hours. I'll have to take it back to my shop and fix it. I'll test it before I call you. Can I contact you on your mobile phone? ,F: Of course, I've learned a lesson today.
(A) M: Excuse me, could you repeat the question? (B) M: Of course you have! But I can still save the files for you. (C) M: You sure did! But I still need to take it away to see what is wrong with the keyboard. (D) M: You sure did! But I still need to take it away if it is ok.
