    Nowhere are the realities of______climate change more apparent than at Earth's thawing poles.

    A.human-driving
    B.human-drive
    C.human-driven
    D.human-drived

    答案：C
    解析：
    本题考察动词的时态和语态，题目意为“没有比融化中的南极和北极更能明显反映人为引起气候变化这一事实的地方了。”由于句子是由nowhere此类有否定意思开头的,需要使用部分倒装。空格处意思为“人为引起，人为造成”，drive的过去分词形式driven这里作名词使用，表被动，和human组成联合短语共同作为定语修饰后面的内容。
