Anna：Hi Jason. Sorry to bother you. I have a question for you.

Jason：OK, what's up?

Anna：I've been having a problem with（有问题） my computer. I know you're an engineer so I thought you might be able to help me.

Jason：I see. What's the problem?

Anna：I have a file（文档） that I can't open for some reason.

Jason：What type of file is it?

Anna：It's a Word document I've been working on. I need to finish it by tomorrow.

Jason：Were you able to open it before, on the computer you're using now?

Anna：Yes, I was working on it last night and everything was fine, but this morning I couldn't open the file.

Jason：Do you think your computer might have a virus（病毒）?

Anna：No, I checked and there weren't any.

Jason：OK. I'm not sure what's wrong. If it's possible, email the file to me and I'll see if I can get it to open.

Anna：OK, I'll do that when I get home. Are you going to be around tonight?

Jason：Yeah, I'll be home after 8PM. Send it to me when you get a chance and I'll call you later.
