People often ask me how, as a man, I became so devoted to improving the quality of women’s lives.  It wasn’t until age forty that I realized what had started me down my career path.

One morning more than thirty-seven years ago, I was awakened by the passing school bus.  I was thirteen years old, living at home with my two younger brothers and our mother, Doris Joy Heavin.  She had just passed her fortieth birthday.  She was a mother of five children and had suffered emotional and physical problems most of her life.  Her doctor had tried various treatments on her with little benefit.

As I awoke to the sound of the passing school bus, my brother Paul came in and told me that I’d better come quickly because mother was sick.  As I knelt beside her bed, I could feel the absence of warmth.  I put my arms around her, first to feel for a sign of life, and then as a final hug.  I took my younger brothers, aged eight and nine, in my arms and gently told them that our mother was in heaven.

Her death was unnecessary.  The high blood pressure causing the blood clot(血栓) that took her life was unnecessary.  Rather than medicate the symptoms, she could have dealt with the cause of her high blood pressure: we now know that exercise and proper nutrition will almost always reduce the causes of high blood pressure and most other chronic(慢性的) diseases.

Many years later, while teaching a fitness and weight loss class to a group of about eighty women, I realized I was subconsciously(下意识地) searching the crowd for the face of my mother.

A.provide proper nutrition                

B.take exercise regularly

C.give up the treatment

A.the author was the oldest child in his family

B.the author’s father died long before his mother

C.high blood pressure is a kind of chronic disease

D.many women were found with blood clot at the time

60.Why did the author think his mother’s death was unnecessary?

A.Because her blood clot wasn’t a deadly disease at the time.

B.Because his mother wouldn’t have died if she had a job.

C.Because her high blood pressure could have been prevented.

D.Because his mother was not treated in the local hospital.
