【题目】It seems that pigeons have a compass inside them that tells them _____ they need to go. That is why they never get lost.
A. what B. where
C. how D. which
在线课程【答案】B
【解析】
考查宾语从句。句意：似乎鸽子体内有一个罗盘，罗盘告诉他们需要去哪里，拿就是为什么鸽子从来不迷路的原因。本句中where引导宾语从句，做动词tell的宾语，where在句中做状语修饰动词go。AD是连接代词，要在句中做主语宾语；how表示方式。故B项正确。
