房门上响起了三下叩击声。

Three blows were struck upon the panel of the door.

如果这是大自然奉上的一份佳肴，给这份宁静加点作料吧，或是因为啄木鸟的叩击声而兴奋起来吧。

Savour the silence, if that's what nature serves up, or thrill to the tap-tap of the woodpecker.

在我躺下不到五分钟，就开始听到有轻轻的叩击声从我床底下传来，吓得我也不敢下去看，只好置之不理，继续睡觉。

I listened for a minute, and that was when I realized that the sound was coming from underneath my bed! I was too afraid to look under it, so I just tried to ignore it and go to sleep.
