I was dog-tired when I got home last night.

秒懂解释

dog-tired ['dɔɡ'taiəd]

adj. [口语、常作后置定语]

极疲乏的，精疲力竭的，疲惫不堪的，累坏了的 [亦作dog-weary]

狗子在熟睡的时候，不论周围环境多嘈杂都吵不醒它。人们认为是狗子太累了，就用 dog-tired 来形容非常疲惫，精疲力竭的状态。也就是我们常说的“累成狗”。

举个栗子

I was dog-tired after working the whole day in the garden.

我在花园里干了一整天的活，累死了。

By dusk we were dog-tired and heading for home.

到了傍晚我们累趴下了，于是回家。
