1)让步状语从句中的倒装形式为：强调对象＋as/though＋主语＋其它部分，强调对象可以是表语(名词，形容词)或状语(副词)。表语为名词时，前面通常不用冠词。

【例如】

Tired as he is, he goes on with his work.Much as he likes her, he does get irritated with her sometimes.Child as he is, he knows how to please the others.

2) be＋主语＋or连接的两个表语。这个句型相当于whether…or…引导的让步从句。

【例如】

Be it cheap or dear, I will take it. We should put our energysintosour work, be it mental like the work of a scientist or physical like the work of a smith.
