听力原文:M: Well, how' s the patient this morning?
W: He appears to have had a very restless night.
M: Oh. Was he in very severe pain?
W: Yes. I' m afraid he was, doctor.
M: Hmm. In that case, I think we' d better increase his dosage of diamorphine.
W: Yes, doctor. By how much?
M: Let' s see. How much is he on at the moment?
W: Five milligrams.
M: Hmm. Increase it to fifty.
W: Fifty? All at once?
M: Yes, that' s what I said, nurse.
W: But that' s an increase of forty - five milligrams.
M:I' m quite aware of that. However, when I operated on the patient yesterday, I found his abdomen was riddled with carcinoma. I' m sure you realize what that means.
W: Yes, I do, doctor. But I still don' t feel I can accept responsibility for administering such an increase.
M: Can't you? What exactly do you suggest, than?
W: That if you' re convinced it' s the right thing to do, you ought to administer the injection yourself.
M: Hmm. I see what you mean. Very well, I will.
