knock at 是一个常用动词短语,核心含义为“敲击(门、窗等)”,其中 knock 为不及物动词,需搭配介词 at 后接具体对象(如门、窗),强调通过撞击发出声音以引起注意 。需注意与 knock the door 区分,后者因缺少介词,含义变为“撞门”,可能引发误解 。
英 /nɒk æt/,美 /nɑːk æt/
基本含义:表示用手或物体轻敲、叩击门、窗等平面,目的是提醒内部人员注意。
例句:Please knock at the door before entering.(进入前请敲门。)
注意:后接具体对象时,at 不可省略,否则语义变为“撞击”(如 knock the door 可能被理解为暴力撞门)。
常见搭配
knock at the door/window:敲门/窗(最常用场景)
例句:A loud knock at the window woke her up.(响亮的敲窗声把她吵醒了。)
a knock at...:一次敲击(作名词短语)
例句:There was a sudden knock at the door.(突然传来一阵敲门声。)
I was wakened by a knock at the door in the middle of the night.(半夜的敲门声把我吵醒了。)
They heard a knock at the front door and stopped talking.(他们听到前门有敲门声,便停止了交谈。)
Just as we were about to have dinner, there was a knock at the door.(我们正要吃晚饭时,有人敲门。)
Knock at my window at eight o'clock and I'll be ready.(8点敲我的窗户,我会准备好。)
