问题补充：

A. Not rich although he is
B. In spite of not rich
C. Though not rich
D. As he is not rich
答案：
A. Not rich although he is
B. In spite of not rich
(答案→)C. Though not rich
D. As he is not rich
解析：考查状语从句的省略：句意：虽然不富有，但是郭明义努力帮助那些贫穷的人。A项错在although不能用于倒装句，B项错在in spite of后面接名词或动名词，D项错在as表示让步含义，需要用倒装句，C项是省略的表达，完整的是though he is not rich，主从句的主语一致的时候，可以省略从句的主语和be动词，选C。
