问题     (46) Yet, after wrapping a flexible cuff around your arm and pumping it up, your doctor frowns and gives you the bad news:you are one of the roughly 60 million Americans who have high blood pressure. Because it can lurk in the body without your knowing it, high blood pressure has been called the silent killler. (47) (48) Depending on how high your pressure is, how you live and what changes you’re willing to make in your lifestyle, treatment can be tailored specifically to you. (49) The first, or top, number is the systolic reading, the pressure of blood against artery walls when the heart beats—the period of highest tension. The second, or bottom, number is the diastolic—the minimum pressure, between beats, when the heart is filling with blood and artery walls are relaxed. If the diastolic goes over 105 and stays there through several readings, that’s the beginning of the danger zone, moderate hypertension, and continued monitoring is essential. Once the diastolic rises above 115, the condition is severe. A diastolic between 90 and 104 falls into the gray area of "mild" hypertension. (50)
A. These drugs can lower blood pressure by getting rid of excess fluid and salt in the body.
B. It is the leading cause of strokes and a major factor in heart attacks and kidney failure.
C. You’ve had no symptoms, no pain, no sense of being sick.
D. For the average adult, a healthy blood-pressure reading is 120 over 80, or lower.
E. Three-fourths of those with high blood pressure are in this category.
F. The good news is that thanks to an explosion of research, science now knows how to defuse the danger, and control the disease.

选项

答案E

解析 选项E所在段落的大意是“如果舒张压超过105而且经过若干次读数仍然停留在那里,这就是危险区,中度高血压的开始,有必要连续监测。一旦舒张压高于115,情况就严重了。90至104之间的舒张压属于“轻微”高血压的灰色区域。四分之三的高血压患者在这一范畴。”
