转述句的六个口诀包括：1) 时态不变，人称随宾语；2) 引号去除，连词保留；3) 时态不变，特殊动词注意；4) 时态变化，时间地点也跟着变；5) 不确定词，一定要改；6) 语气不变，情态动词留。这些口诀有助于更好地理解和运用转述句。
- 时态不变，人称随宾语
转述句中的时态一般保持不变，而人称则随宾语的变化而变化。例如： He said, "I am happy." 可以转述为 He said he was happy.
- 引号去除，连词保留
转述句一般不需要引号，但是需要保留引导原话和转述句之间的连词。例如：She said, "I will go to the store." 可以转述为 She said that she would go to the store.
- 时态不变，特殊动词注意
有些特殊动词在转述句中需要特别注意，如 can, may, must 等。例如：He said, "I can swim." 可以转述为 He said he could swim.
- 时态变化，时间地点也跟着变
转述句中的时间和地点一般需要根据上下文进行调整。例如：She said, "I am going to the party tomorrow." 可以转述为 She said she was going to the party the next day.
- 不确定词，一定要改
转述句中的不确定词如 some, any, no, every 等一定要进行适当的改动。例如：He said, "I have some money." 可以转述为 He said he had some money.
- 语气不变，情态动词留
转述句中的情态动词一般需要保留原来的语气。例如：She said, "I might go to the concert." 可以转述为 She said she might go to the concert.
