听力原文：MB The copy machine isn't working again. Has anyone called in about it yet? WB Yes, I spoke to the repair man this morning. I told him the paper's still getting stuck in the same spot as last week when he was here. He said he'd be here around eleven. MB Oh good, you were able to talk to the same man. He seemed very competent. I'm surprised it's broken again. WB It's not his work that's the problem—last week he told me we may need to replace a part. If that's true, it might make more sense to just replace the whole machine this one's at least five years old. New ones aren't that expensive. What is learned about the copy machine?
