She (）a lot in her journey.
A. must suffer
B. must be suffered
C. should have suffered
D. must have suffered
题目解答
答案
D. must have suffered
解析
本题考查情态动词的完成时态的用法，核心在于根据语境判断对过去的推测。关键点包括：
- 时间状语
in her journey暗示动作发生在过去； - suffer为不及物动词，不可直接用于被动语态；
- must have done表示对过去的肯定推测，符合题意。
选项分析
A. must suffer
- 表示现在或一般情况的推测，但
in her journey表明动作已发生，时态不符。
B. must be suffered
- 错误：
suffer为不及物动词，不可直接用于被动语态（除非搭配from，如suffer from）。
C. should have suffered
- 表示过去本应发生但实际未发生，与题意中“经历困难”的肯定推测矛盾。
D. must have suffered
- 正确：表示对过去动作的肯定推测，符合“在旅行中一定经历了许多困难”的逻辑。
