A、Sooner or later
B、Some day or other
C、Every now and then
D、Time and again
【正确答案】：D
【题目解析】：答案解析：在第27题中，上下文提到“研究证明这一点：伟大的创造性突破通常只发生在长期的奋斗之后。”这里需要一个短语来表达“一再地，反复地”的意思，用以强调这种奋斗是反复出现的，并且是创造性突破的常见前提。选项D“Time and again”恰好符合这一意思，表示“一再地，不时地”，因此是正确答案。其他选项如“Sooner or later”表示“迟早”，“Some day or other”表示“某一天”，“Every now and then”表示“时而，偶尔”，均不符合上下文的语境和含义。
