问题 For three-quarters of its span on Earth, life evolved almost ______ as microorganisms.

选项 A、precisely
B、instantly
C、initially
D、exclusively

答案D

解析副词词义辨析题。由three-quarters和almost可知，生命在进化过程中，有四分之三的时间几乎都以单一的形式存在。exclusively表示“排外地，专有地”，符合句子语境，故D正确。precisely表示“精确地，正好”；instantly表示“立即地，即刻地”；initially表示“最初，开头”。
