M: Good morning, Mrs. Beta Stump. I'm your doctor, Brown. Your GP asked me to see you at short notice because the blood test he did was abnormal. Did he explain this to you?
W: I didn’t understand what he was saying. I’m very frightened because he told me to come here so quickly. It must be serious.
M: Yes, well, we’re not yet certain about the diagnosis, but the blood test did show that you were very anemic and there seemed to be some abnormal white blood cells, We’ll need to do some more tests and I’ll explain about them later.
Q: What does the man do?
【解析】推断题。对话中提到:Your GP asked me to see you at short notice because the blood test he did was abnormal(你的主治医师让我尽快见你,因为血液检查有问题 ),由此推断该男士为血液病专家。
