M: Hello, Miss. What brings you here today?
W:(13)I am not feeling myself. This has been going on for days, and I have a sore throat.
M: Don’t worry. Let me have a check. Do you have a fever or headache?
W: No. But I’m afraid I felt a little dizzy when I got up this morning.
M: Well, open wide and say "Aaa".
W: Aaa.
M: Eh, your throat looks a little red. Let me check your tongue... Mmm, it seems okay.
W: Doctor, what’s the matter with me?
M: Well, there is nothing serious, and you needn’t worry. Now tell me, did you sleep late recently?
W: To tell you the truth,(14)I stayed up very late last week and only slept four or five hours every night. My term paper was crushing the vitality out of me. I tried my best to prepare for it.
M: That may explain something. You are wearing yourself out.(15)Now what you should do is have a good rest and drink more water.
W: That’s all? I thought you would give me a lot of medicine and ask me to stay in bed for a couple of days. Thank heavens! I almost thought I was dying!
M: You really needn’t worry. Just take care of your bedtime. Lacking of sleep can lead a lot of problems. You don’t want to be ill during the summer vacation, do you?
W: Of course not. Thank you so much. Goodbye!
M: Bye.
