"he moved off into the darkness"
"a ghostly apparition at midnight"
"a shadow over his happiness"
"there wasn't a trace of evidence for the claim"
"a tincture of condescension"
"he felt secure in his father's shadow"
"he received little recognition working in the shadow of his father"
"the poor child was his mother's shadow"
"The police are shadowing her"
"This year's debt dwarfs that of last year"
The mountains were shadowing into blackness.
群山渐渐消失在黑暗中。
