说了这么多，咱们知道了如何去识别例证题，也知道了去哪里找答案，那么我们就利用一下2003年的一道真题来看看例证题的完整解题思路，在往下滑看咱们的解题思路和答案之前，建议同学们可以自己先尝试做一做哈：

Death is normal; we are genetically programmed to disintegrate and perish, even under ideal conditions. We all understand that at some level, yet as medical consumers we treat death as a problem to be solved. Shielded by third-party payers from the cost of our care, we demand everything that can possibly be done for us, even if it’s useless.（观点） The most obvious example is late-stage cancer care（例子）. Physicians—frustrated by their inability to cure the disease and fearing loss of hope in the patient—too often offer aggressive treatment far beyond what is scientifically justified.

57. The author uses the example of cancer patients to show that ______.

[A] medical resources are often wasted

[B] doctors are helpless against fatal diseases

[C] some treatments are too aggressive 

[D] medical costs are becoming unaffordable
