第1题:
Question 16: According to the passage, why does more screening not always equal better health?
【试题解析】题干为：根据文章，为什么更多的筛查并不总是意味着更好的健康？文章开头提出but more screening doesn’t always equal better health（但更多的筛查并不总是意味着更好的健康），接着解释道In fact, unwarranted laboratory tests do more harm than good.（事实上，未经授权的实验室测试弊大于利。），说明未经授权的筛查测试危害更大。因此C选项“The unwarranted screen tests may do more harm than good to health.（未经授权的筛查测试可能对健康弊大于利。）”正确。
第2题:
Question 17: What is the main concern even with true positive tests?
【试题解析】题干为：即使是真阳性检测，主要的关注点是什么？由A primary concern is over-treatment of true positive screening test.（一个主要问题是真阳性筛查检测的过度治疗。）可知，针对真阳性筛查检测的一个主要问题是过度治疗。因此B选项“Over-treatment.（过度治疗。）”正确。
第3题:
Question 18: What will be probably discussed next in the passage?
【试题解析】题干为：这篇文章接下来可能会讨论什么？本文在首句指出讨论的核心是“更多的筛查并不总是意味着更多的健康”，然后分别从“未经授权的实验室检测弊大于利”以及“针对真阳性筛查检测的过度治疗”两个方面来说明，指出其弊端后，文章转至“这并不意味着你应该完全放弃医学检查”，指出有些筛查的必要性，所以在说明了有症状的患者筛查的必要性后，应该要讨论筛查对于无症状的健康人员的必要性。因此D选项“The testing advice for people without symptoms.（对无症状人群的检测建议。）”正确。
【听力原文】
Today, there are thousands of lab tests and imaging procedures to screen for illnesses, but more screening doesn’t always equal better health. In fact, unwarranted laboratory tests do more harm than good. For example, many screening tests come back with false positives that may cause needless anxiety and include expensive imaging testing, even invasive procedures. A primary concern is over-treatment of true positive screening test. One example is the PSA test for prostate cancer. Although the PSA may lead to the detection of prostate cancer. In many men, cancer will never cause harm if left alone and treatment is both useless and fraught with side effects. This doesn’t mean you should give up medical test altogether. For people who have symptoms, the proper use of advanced tests and procedures enables detection and treatment of important medical conditions.
