【正确答案】 C

【答案解析】[听力原文]
Diabetes mellitus is the fifth leading cause of death by disease in the United States. It is an ancient disorder. As a matter of fact, the name is from the Greek words that mean "run through". The Greeks noticed that the afflicted urinated more often and larger than normal amounts. The word "mellitus" came along in the 1600s. The word had the meaning of "sweet", and was added to distinguish this disease from a completely separate one called diabetes insipidus associated with a disorder of the pituitary gland.
Prior to 1921, diabetes mellitus was usually fatal. Diabetes mellitus is a complex disorder in which the body is unable to convert sugars and starches properly into the energy necessary for daily activity. In this condition, insulin action is deficient—not enough is produced. This malfunction of insulin action causes the body to lose its main source of energy—sugar. It also disrupts protein and fat metabolism.
Long-term complications may affect blood vessels, the nervous system, kidneys, and the eyes. At present, there is no cure for this chronic disorder.
In the United States alone, a large number of deaths a year are attributed directly to diabetes.
An additional over 100,000 deaths occur annually as the result of its complications. Almost 50% of amputations of the foot and leg among adults, 20% of all cases of kidney failure, and 15% of all blindness are the result of diabetes.
