本题考查词汇的理解与运用，解题思路是根据句子的语境和语义来选择合适的词汇。

第一空

句子表达的是个人理解“承认”自己行为这一概念的重要性。“acknowledge”有“承认；认可”的意思，“acknowledging their own actions”表示“承认自己的行为”，符合语境。而“pay for”意为“为……付款；为……付出代价”，“interpret”意为“解释；诠释”，均不符合此处语义。所以第一空应选A：acknowledging。

第二空

前面提到每个决定都有积极和消极的后果，这里说我们最终必须“面对”这些后果。“face”有“面对”的意思，“face the consequences”是常见搭配，表示“面对后果”。“pay for”虽然也有“为……付出代价”的意思，但这里强调的是面对后果这一行为，而不是单纯的付出代价，所以第二空应选C：face。
