【新概念英语 语法直引变间引】的讲解主要涉及了如何将直接引语转换成间接引语的规则。直接引语是直接引用他人的话语，需要用引号括起来；而间接引语则是转述别人的话，通常作为宾语从句出现，不用引号。
1. **人称变化**：
- 当直接引语中的第一人称（如"I"或"We"）在变成间接引语时，需要与主句的主语保持一致。
- 第二人称（如"you"）要根据主句中的宾语来决定，如果是对某人说话，则变成与该宾语相对应的人称（例如，"he"/"she"/"it"/"they"）。
- 第三人称（如"He"，"She"，"It"，"They"）在转为间接引语时，人称保持不变。
例子：
- "She said, ‘I like Tennis.’" -> "She said that she liked tennis."
- "He said to Lily, ‘You must get up early.’" -> "He told Lily that she must get up early."
- "She said to me, ‘They want to help him.’" -> "She told me that they wanted to help him."
2. **时态变化**：
- 如果主句是现在时态，从句的时态保持不变，如："He says, ‘I will do it tomorrow.’" -> "He says that he will do it tomorrow."
- 若主句是过去时态，从句的时态通常会向过去时态移动一级，如："He said, ‘I am doing it now.’" -> "He said that he was doing it then."
- 但有特殊情况，比如直接引语表示客观事实或在过去特定时间发生的事件，间接引语时态保持不变。
3. **疑问句的转换**：
- 陈述句直接引语转为间接引语时，通常由连词"that"引导，可以省略。
- 一般疑问句变为间接引语，用"whether"或"if"引导，同时将原句的"say"改为"ask"，语序调整为陈述句语序。
- 特殊疑问句同样用"whether"或"if"引导，疑问词放在句首，其余部分按陈述句结构排列。
例子：
- "He asked, ‘Do you have any difficulty with pronunciation?’" -> "He asked me whether I had any difficulty with my pronunciation."
- "‘Are you at home yesterday?’" -> "She asked me if I was at home the day before yesterday."
4. **情态动词的变化**：
- 在从直接引语转换到间接引语时，情态动词如"can", "will", "may", "must"等需要相应调整，如"can"变为"could", "will"变为"would"等。
例子：
- "He asked, ‘Can you help me?’" -> "He asked me if I could help him."
转换直接引语和间接引语时，需要考虑人称、时态、语序以及情态动词的变化，确保从句能准确反映主句所表达的意思。理解并掌握这些规则对于学习英语语法至关重要，特别是在写作和口语交流中正确地传达信息。
