be duty bound to 是不是存在语法错误?
正确的说法是不是应该是 be in duty bound to?

e duty bound to没有错

我有义务去探望爷爷奶奶.
You are duty bound to help those poor.
你有责任帮助穷人.
be in duty bound to do也对.

be duty bound to 是不是存在语法错误? be bound to it's bound to be 用be bound to 造句 be bound to=什么半助动词 be bound to He is bound in duty to obey.中bound作什么解释 sb be bound to do sth是什么意思 be bound to和must的区别? It is bound to be confusing be bound to do 还是doing 英语.是不是语法错误?应该是any to be organized吧
