为什么要用beingHe apologized to the chairman for being late.I apologize for not being able to join you for dinner.为什么这两个句子都要用being
两个句子中的 for 都是介词,后面要求用名词或动名词充当介词宾语.
  第一个句子中的 late 是形容词,不能直接用作宾语,要么变成名词 lateness,要么加上系动词变成动名词短语being late,这样才可以用作介词宾语.
  同理,第二句的 be able to 是系表结构的复合情态动词,要用作介词 for 的宾语,必须将其改为动名词being able to 方可.

因为介词后面必须接名词性的词或词组。late、able 是形容词,加上 be 的 ing 形式(使之成为“动名词”的系动词+表语结构)就组成了“介词短语”:
for being late—— 迟到
for not being able to —— 不能(做......)

be late 迟到
又 for 介词 要加ing
