在英语语法中，直接引语和间接引语之间的转换是一个重要的知识点。这种转换不仅涉及到句子结构的变化，还涉及时态、人称以及标点符号的调整。今天我们就来详细讲解如何将直接引语变为间接引语，并通过一些练习题巩固所学知识。
一、直接引语与间接引语的基本概念
直接引语是指引用他人的话时，原文基本保持不变，通常用引号括起来。例如：“I am happy today,” she said.
间接引语则是对别人所说的话进行转述，不使用引号，且需要根据语境调整时态、人称等。例如：She said that she was happy today.
二、直接引语变间接引语的原则
1. 时态变化
- 如果主句是一般现在时或将来时，则从句时态保持不变。
- 如果主句是过去时，则从句时态通常向前推一个时态。例如：
- She says, “I will go to the park.” → She says that she will go to the park.
- She said, “I went to the park yesterday.” → She said that she had gone to the park the day before.
2. 人称代词的变化
根据说话者与听话者的不同关系，人称代词需要相应地变化。例如：
- “I am tired,” he said. → He said that he was tired.
- “We will win the game,” they said. → They said that they would win the game.
3. 标点符号的变化
直接引语需要用引号括起来，而间接引语则不需要。
4. 连接词的选择
根据原话的内容选择合适的连接词，如that、if/whether、what、how等。
三、具体例子解析
例1：
- 直接引语：“I am going to study abroad next year,” John said.
- 间接引语：John said that he was going to study abroad the following year.
例2：
- 直接引语：“Do you know where the library is?” she asked.
- 间接引语：She asked if I knew where the library was.
四、练习题
1. “I am hungry,” Mary said.
Mary said that ________.
2. “Where did you buy this book?” Tom asked.
Tom asked ________.
3. “I have finished my homework,” Lucy said proudly.
Lucy said proudly that ________.
4. “Can you help me with my math problem?” he asked.
He asked ________.
5. “What time does the train leave?” she inquired.
She inquired ________.
以上就是关于直接引语变间接引语（宾语从句）的一些基本讲解及练习题。希望大家能够通过这些练习掌握这一知识点，并灵活运用到实际交流中去！答案如下：
1. Mary said that she was hungry.
2. Tom asked if I knew where the book was bought.
3. Lucy said proudly that she had finished her homework.
4. He asked if I could help him with his math problem.
5. She inquired what time the train left.
