Lesson 101-104 | 核心句型：寄明信片、他说他很快 | 语法点：直接引语变间接引语、宾语从句时态变化、人称变化规则
直接引语就是直接引用别人的话，放在引号里；间接引语就是用自己的话转述别人的话，不放在引号里，通常构成宾语从句。
直接引语：
间接引语：
当主句的谓语动词是一般过去时（said, told等），间接引语的时态要相应地向后推移：
| 直接引语时态 | 间接引语时态 | 例句 |
|---|---|---|
| 一般现在时 | 一般过去时 | He said: "I am happy." → He said that he was happy. |
| 现在进行时 | 过去进行时 | He said: "I am working." → He said that he was working. |
| 现在完成时 | 过去完成时 | He said: "I have finished." → He said that he had finished. |
| 一般过去时 | 过去完成时 | He said: "I bought a car." → He said that he had bought a car. |
| 一般将来时 | 过去将来时 | He said: "I will go." → He said that he would go. |
| 过去完成时 | 过去完成时（不变） | He said: "I had finished before 5 o'clock." → He said that he had finished before 5 o'clock. |
特殊情况：
人称变化遵循"一随主，二随宾，第三人称不更新"的规则：
一随主：直接引语中的第一人称随主句的主语变化
二随宾：直接引语中的第二人称随主句的宾语变化
第三人称不更新：直接引语中的第三人称不需要变化
too的用法：太……（表示否定意义，超过了需要的程度）
enough的用法：足够……（表示肯定意义，达到了需要的程度）
