答案

参考答案:E

解析:本题考点为流行病学研究的主要问题。流行病学是以疾病的分布为起点来认识疾病的,即通过收集、整理并考察有关疾病在时间、空间和人群中的分布特征,去揭示疾病发生和发展的规律,为病因研究提供线索。在此基础之上,利用流行病学特有的分析性、实验性研究方法去探索和验证病因。在对疾病的病因有一定认识的前提下,制定相应的策略和措施,达到预防和控制疾病的目的。.与此同时,流行病学不断总结各种实践经验,提炼疾病防制成果,借鉴其他学科的先进技术,创造并发展了流行病学自身特有的方法。

The Healing
Jim and his wife, Connie, were shocked by the loss of their four-month-old son—Joshua, whose life was taken by SIDS—sudden infant death syndrome.
Thirty hours ago Jim drove to the baby-sitter’s home to  1  Joshua. It was a  2  trip, like the one he made five days every week. He arrived, and little Joshua could not be   3   from his nap. The next few hours were a time of life and death: the racing ambulance, swift-moving doctors and nurses….but 12 hours later, at children’s Hospital,   4  the doctors had exhausted all  5 , little Joshua was gone. Yes, they wanted   6  of Joshua’s usable organs to be donated. That was not a   7  decision for Jim and Connie, a loving and   8  couple.
The next morning dawned and many things had to be arranged. Telephone calls and funeral plans.   9  one point Jim realized he needed a  10 .When Jim settled into the chair   11   the barber’s, he began to   12   the past hours, trying to   13  some sense of it all.   14  had Joshua, their first-born, the child they had waited so long for, been taken so soon….he had   15  begun his life….The question kept coming, and the pain in Jim’s heart just   16  him.
While talking with the barber, Jim mentioned the organ donations, looking at his watch: “They are transplanting one of his heart valves(瓣膜) right now.”
The  17  stopped and stood motionless. Finally she spoke, but it was only a whisper. “You’re not going to believe this….but about an hour ago the customer sitting in this chair wanted me to hurry   18  she could get to Children’s Hospital. She  19  here so full of joy….her prayers had been answered. Today her baby granddaughter is receiving a  20  needed transplant—a heart valve.”
Jim’s healing began.
