be able/unable to 的to能省略吗?

be not able to/be unable to/can't 有什么区别~

not be able to:表示原本可以做到而由于某种原因未能做到。
be unable to:表示没有能力做到。
can't:表示不想或不愿意做。

只有当引导词that做定语从句的宾语成分时可以省略,其他情况不能省略。
The man [(that) I saw in the street yesterday] is my teacher.
The man [that said hello to me yesterday] is my teacher.
The village [(that) I often visit] is my hometown.
The village [that becomes a modern city] is my hometown.
注:带()的that可以省略,[ ]括着的是定语从句。

be able to 是固定用法,相当于情态动词,后跟动词原形
to 是不能省略的

我认为所给的题目不正确或是不规范的用法
