Night is the counterpart of day.
黑夜与白天相辅相成。
One that is foreshadowed by or identified with an earlier symbol or type, such as a figure in the New Testament who has a counterpart in the Old Testament.
先前原形先前的标记或模型所预示或表明的原形，如《新约》中的人物在《旧约》中有对应的形象
I racked my memory in vain for its counterpart in literature: perhaps you could think of one.
我绞尽脑汁也想不出它在文学中的对等物，也许你可以想出一个。
