参考答案
参考解析
解析：此空处的词作宾语从句的主语，又根据句意可知，此处的主语应表示人，故选D。
文章中第一段中的皮肤反应测验的目的是为了诊断老年痴呆症。此处承接上文内容，故选D。
由后半句中的diagnose it可知，此处应填disease。
此空处的副词用来修饰之后的diagnose这个动词，比较四个选项，只有B项accurately （准确地）符合文意。
此处if引导的成分在句中作插入语，表达的意思为“如果确认的话”，故选C。
此处表达的意思为老年痴呆症是导致老年人脑力下降的唯一最大的原因。故此空处应填cause。
此处所表达的意思是：仅在美国，每年就有250万到400万美国人遭受老年痴呆症的困扰，alone表示“仅仅”，故选D。
本句话的意思为：目前还没有针对这种疾病的确切疗法。故此处用treatment。
本句中that之后陈述的是研究人员发现的一个事实，并没有表示预测、期望或警告。因此本题选A。
由文中可知，老年痴呆症是身体的生理病变引起的结果，result from意为“因……而产生”。
此处的含义为这种缺陷会对大脑中的细胞产生影响，故选A。
由本段第二句中的another critical element可知，此处应选critical。
call for为固定搭配，意为“要求，需要”。
此处表述的内容为控制钾的流动的管道。故此空应填govern。
根据句意可知，此项诊断性测试如果能得到验证，那将会是一个很重大的进步，故选C。
