A、interesting
B、same
C、common
D、alike
【正确答案】：C
【题目解析】：第23题要求根据语境选择合适的形容词来描述失眠患者的一个普遍特征。从上下文中可以看出，这句话描述的是失眠患者的共同问题，即他们无法完全放松。 选项A "interesting" 意为“有趣的”，与上下文描述的失眠问题不符，因此排除。 选项B "same" 意为“相同的”，虽然它表示一种共性，但通常用于比较两个或多个事物之间的相似性，而在此处，我们需要一个更具体的形容词来描述失眠患者的一个普遍特征。 选项C "common" 意为“普遍的，常见的”，正好符合语境，用来描述失眠患者普遍存在的问题，即无法放松。 选项D "alike" 通常用于表示两个或多个事物在外表或性质上相似，但在这里并不适用，因为它不强调普遍性。 因此，根据上下文和选项的含义，正确答案是C "common"，它准确地描述了失眠患者普遍存在的问题。
