单项选择题

(C)


Is there anything more important than health I don’t think so. "Health is the greatest wealth," wise people say. You can’t be good at your studies or work well when you are ill.
If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor.
The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest Xrayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.
Speaking about doctor’s advice, I can’t help telling you a funny story.
An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.
He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: "Eat at pleasure, drink with measure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day.
A month later the gentleman came into the doctor’s office. He looked much more cheerful and much happier. He thanked the doctor and said that he had never felt a healthier man.
"But you know, doctor," the man went on saying, "it’s not easy to begin smoking at my age.\

The underlined part means "______".

A. he was feeling better than ever
B. he wasn’t a healthy man
C. he was feeling worse than before
D. he will be well again
