问题 Nowhere in nature is aluminum found free, owing to its always______with other elements, most commonly with oxygen.

选项 A、combine
B、combined
C、being combined
D、having combined

答案 C

解析 owing to是介词短语，后面应跟名词或动名词，its being combined with otherelements为动名词短语。其他三个选项均不合适，因为combine为原形动词；combined为过去分词；having combined为主动态。
