2 . “Health is the greatest wealth,” wise people say.     1     If you have a headache, tooth-ache, backache, or bad pain in the stomach, I think you will go to the doctor.

The doctor will examine your throat, test your blood pressure, take your temperature, sound your heart and lungs, check your teeth or have your chest X -rayed.     2     The only thing you have to do is to follow his advice.

    3     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.     4     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.     5     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.”

A．He looked cheerful and happy.

B．All these will cost a lot of money.

C．He was more worried about his illness.

D．After that he will advise some treatment of some medicine.

E．You can’t be good at your studies or work well when you are ill.

F．Speaking about doctor’s advice, I can’t help telling you a funny story.

G．He was suggesting the rule “Eat at pleasure, drink with measure and enjoy life as it is.”

3 . If doctors want to test you for something, they’ll usually take a blood or urine sample. But wouldn’t it be much more convenient if they just asked you to breathe through a special instrument?

In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers’ alcohol consumption by testing their breaths.

Just like blood and urine, your breath contains lots of “metabolites” —the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “breathprints”, according to Science Daily.

Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids(液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.

On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers’ chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn’t change much throughout the day, reported BBC.

“Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.
