     根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
     Is there anything more important than health? I don't think so."  1  " 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  2   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 X-rayed. After that he will advise some treatment, or
some medicine.  3  Speaking about doctor's advice, I can't help telling you a funny story.

weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said

good-rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take
long walks.   4  : "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 should not smoke more than one cigarette a day. 
       5   He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier
man."But you know, doctor," he said, "it's not easy to begin smoking at my age."
