A、Thankful. B、Admiring. C、Resentful. D、Respectful. C根据男士的话All this time you have been prescribing tablets for heart burn，and it

W: Well, you’ 11 probably have an operation to remove the bowel, or some of it. It’ s too diseased to save, I’ m afraid.
M: How will I go without a bowel? How can I live without a bowel?
W: During the operation, they will fit you externally with a colostomy bag.
M: You mean the bag of shit hanging inside of my clothes?
W: Well, that’ s perhaps an unnecessarily cruel way of putting it. But, broadly speaking, yes. It is sealed and odor-free. They’ 11 show you how to empty it and change it for yourself. And nobody need ever know that you’ ve got one unless you tell them.
M: Well, thanks a lot. Cancer of the bowel! All this time you have been prescribing tablets for heart burn, and it turns out that I got cancer of the bowel? Oh, thanks a million. What next? How long will I go on now? Will I be able to live any kind of normal life? Tell me \
W: I prescribed for you on the basis of the symptoms you yourself described to me. Only a colonoscopy can reveal your condition. No doctor could diagnose your condition without the hospital tests that I arranged for you. And yes, you will be able to live a pretty normal life and go work, and everything. Nobody need ever know a thing unless you choose to tell them. And you have full life ahead of you.
