11（）
A．disturbing
B．annoying
C．confusing
D．surprising
参考答案：C
解析：
语义衔接题。开篇首句提到：越来越多的居民、公司、政府机构使用录音电话接收信息或发出指令。由此引出本文“录音电话”这个主题。第二句后半部分提到play messages that are difficult to understand(播放令人难以理解的信息)，由句中的or可推知该句前后两部分表达的意思相近，后半句是对前半句的补充说明，因此选confusing，表示录音电话中的“指令不清，让人摸不着头脑”。
[避错指导] disturbing意为“烦扰的”，annoying意为“恼人的，讨厌的”，由文章首句可知越来越多的人选择使用录音电话，显然人们认为它很实用。如果觉得录音电话是让人厌烦的东西，大家就不会使用它了。 surprising意为“惊人的，不可思议的”，如放在此处不符合上下文语境，句中未表示出电话录音让人惊异。
