步骤 1：理解句子结构和动词用法
在英语中，动词的不定式形式可以用来表示目的、结果、原因等。根据句子的结构和上下文，选择正确的不定式形式。
步骤 2：分析每个句子
1. "Why not advise the manager __ (reconsider) his decision"
- "advise" 后面跟动词不定式，所以用 "to reconsider"。
2. "Don't forget to have John __ (come) for dinner tomorrow."
- "have" 后面跟动词原形，所以用 "come"。
3. "We both heard him __ (say) that he was leaving."
- "hear" 后面跟动词原形，所以用 "say"。
4. "Students are made __ (finish) the research paper within a month."
- "make" 后面跟动词原形，所以用 "finish"。
5. "Nick was reminded __ (post) the Christmas cards."
- "remind" 后面跟动词不定式，所以用 "to post"。
6. "I saw the cat __ (jump) off the chair."
- "see" 后面跟动词原形，所以用 "jump"。
