M: Good morning. Doctor.
W: Good morning, Mr. White. What can I do for you?
M: I have a sore throat.
W: Can you describe it in detail?
M: I get a scratchy throat and it becomes very pain when I swallow. It has lasted for three days and I ignored it at first but it became worse instead of alleviating. Now I can hardly drink water without pain. It' s really annoying, because I have to deliver an important lecture the day after tomorrow. I become very worried about my voice.
W: I see. Did anything unusual happen during the past three days?
M: Nothing unusual as far as I can ... Oh, wait! I moved my house from the old address to the new apartment in the downtown last week.
W: That's the cause. When a new house is finished, the chemical vapours being given off by paint, glue and other construction materials and moisture will linger for a long time in the house. People who breathe and live in such houses will surely get sick.
M: But what should I do. There is no time and I have classes.
W: Don't worry. I will prescribe some medicine to alleviate the pain.
M: Thank you doctor.
