​be worried to do/about doing/that有什么区别

be worried to do/about doing/that有什么区别？

be worried that 后面应该接句子。如：The child was worried that his father would die. 那个孩子担忧爸爸会死。（摘自《外研社英汉多功能词典》2008年7月第1版）

be worried about 后面接名词、代词或者动词的-ing形式。如：We are very worried about our future. 大家对前途忧心忡忡。（摘自《麦克米伦高阶英汉双解词典》）We were really worried about you ! 大家确实为你担忧！（摘自《牛津英语搭配词典》第2版）People are worried about losing their jobs. 大伙都非常担忧会丢了工作。（摘自《朗文多功能英汉双解词典》第五版）

我查阅了不少词典，没找到be worried to do 的例句。
