与昆虫有关的短语，多半都是贬义的，如之前学习过的习语 ants in pants 的寓意是“坐立不安”，还有接下来的 bug someone，可以意为“使人心烦，令人讨厌”，这里 bug 是动词，意为“使烦恼，使恼怒，装窃听器”，这个习语的寓意：
to bother or irritate someone
打扰或激怒某人
used to describe a person who is annoying or irritating
用来形容一个烦人或使人生气的人
to put a recording device on someone so that all of the moves that they make can be recorded and used against them as evidence
把录音设备放在某人身上，记录他们的所有举动并作为证据
例如：
The squadron leader bugged the military man in order to find out if he was a spy for the enemy.
中队队长装窃听器来窃听那个军人，以查明他是否是敌人的间谍。
解析：in order to 只引导目的状语从句，而 so as to 既可以引导目的状语从句，也可以引导结果状语从句，例如：
She’s afraid of making any noise so as to wake up the baby.
她怕发出响声弄醒孩子。

解析：ask sb not to do sth 表示要求别人别做某事。
