5（）
A．impossibly
B．hardly
C．always
D．usually
参考答案：D
解析：
语义衔接题。该句中that引导的是定语从句，修饰先行词a recorded message。接下来，又提到了录音电话留言信息的内容：Hello(你好)。根据常识可知，通常录音电话都这样说，希望来电者留言，四个选项中只有usually(通常)符合上下文语义。
[避错指导] impossibly意为“不可能地，办不到地”，显然不符合此处的语境。hardly意为“几乎不”，表示否定含义，与impossibly类似，句中不可能出现表示否定意义的副词。always意为“始终，永远”，与usually相比过于绝对，不符合常识。
