同学好~

sibling泛指兄弟姐妹，可能是兄、弟，也可能是姐、妹；单数复数都可能出现，用在泛指这种同父同母的亲属关系居多，经常是不能确定到底是兄弟姐妹之间的哪种，比如：
The remaining 22% lived in the home of another family member (such as a grandparent, in-law or sibling), a non-relative, or in group quarters like college dormitories.
A calm, rule-following child might respond better to a different sort of parenting than a younger sibling.
His siblings are in their twenties.

希望帮到同学~
