__________they are ,they have the courage to overcome the difficulty .
A.Poverty as B.Poor though C.Poorly as D.Although poor
答：B
译：尽管他们们穷,但是他们有克服困难的勇气.
析：as 作为连词,用法较多,引导让步状语从句是,必须将表语、状语提到句首.（严格来说,不属于主谓倒装）,相当于though/ although引导的状语从句.though这个连词也可以“倒装”.
如：Young as/though he is,he knows a lot.尽管很小,但他知道很多.
=Though he is young,...
值得注意的是,如是表语是a+可数名词单数,“倒装”时,省去A：
Child as he is,he knows a lot.=Though he is a child,he knows a lot.
A项排除,不在于它是名词,而在于主表不当.他们是"人" ,是“穷的”,但不是“贫穷”.
C项是副词,更不通.排除.
D项语序混乱,应为：Although they are poor,也排除.
