题目解答
答案
C. If you make a great effort to keep fit with exercise, it will pay off in the long run.
解析
本题考查条件状语从句的用法及固定短语的搭配。解题关键在于：
- if引导条件状语从句的正确使用；
- "pay off"的完整表达形式（需搭配"in the long run"表示"迟早、最终"）；
- 句子结构的完整性（从句与主句的逻辑关系）。
选项分析
选项C正确的原因
- if引导从句：正确使用条件状语从句结构
If + 主语 + 动词... - 完整表达时间概念：
in the long run完整表达"迟早、最终"的含义 - 保留核心动作：
keep fit with exercise完整保留原文"健身锻炼"的含义
错误选项排除
- 选项A：缺少
in the long run，无法表达"最终"的含义 - 选项B：
keep fit后缺少with exercise，信息不完整 - 选项D：省略
if，导致主句与从句逻辑关系错误
