问题 Smart dust sensors can do all the following EXCEPT ______.
If connection between two sensors is blocked, the network will automatically ______.
选项 A、replace the sensor involved
B、repair the sensor involved
C、ignore the sensor involved
D、destroy the sensor involved
答案C
解析 原文第三段的最后一句说：If any one connection is interrupted，the sensors will self-correct and pass the information on to the next available sensor．一旦一个连接中断了，传感器将会自我更正，把信息传送到下一个传感器上。可以推断出原文的意思是忽略传感器，所以选项C是正确的。选项B有很强的干扰性，pass the information on to the next available sensor并没有要修复的意思。只有ignore=self-correct最贴近。考生平时应重点练习这类题型，仔细推敲词汇间的细小差别。
