John is a parent of two children. (约翰是两个孩子的家长。)

The parents of the missing child have been notified. (失踪儿童的家长已被通知。)

Many parents are concerned about the rise in school fees. (许多家长担心学费的上涨。)

家长在英语中还可以表示为 "mother" 或 "father"，例如：

Mary is a single mother. (玛丽是单亲妈妈。)

Jack is a father of three. (杰克是三个孩子的父亲。)
