duty后面是接不定式还是of doing sth作宾语

问题描述

假若要表示有责任或义务做某事，名词 duty 后面是接不定式 to do sth 作定语，还是接介词结构 of doing sth 作定语？

老师答疑

沅老师：

要表示有责任或义务做某事，duty 后可既可接不定式也可接 of doing 结构。如：

A man has a duty to earn money for his family. 男人有挣钱养家的责任。

Every citizen has the duty of defending his country. 每个公民都有保卫祖国的责任。

黎老师：

duty of doing 的例句:

He took on the duty of maintaining the family home. 他承担了养家的责任。（《牛津英语搭配词典》英汉双解版第2版p.529）

duty to do的例句:

You are under a statutory duty to keep accurate records. 你有做好准确记录的法定义务。（《牛津英语搭配词典》英汉双解版第2版p.529）
