Life is like a long race _______ we compete with each other to go beyond ourselves.

Life is like a long race _______ we compete with each other to go beyond ourselves.
A. where B. which C. that D. what
【答案】A
【解析】
【详解】考查定语从句。句意：生活就像一场长跑，我们彼此竞争，超越自我。空格后的句子是由a long race所引导的定语从句。在定语从句中，缺地点状语，表示在这场长跑中，所以我们用关系副词where进行引导。故此题选A。
