dawn

When dawn broke (= the first light of the day appeared ) , we were still 50 miles from Calcutta.

破晓的时候，我们离加尔各答还有50英里。

I was up at the crack of dawn (= very early in the morning ) to get the plane.

我一大早就起来赶飞机。

We worked from dawn to dusk (= through the whole day while it is light ) .

我们从早干到晚。

the cold light of dawn

清冷的晨曦
