【强调句句型】在英语语法中，强调句句型是一种用于突出句子中某一成分的表达方式。它常用于口语和书面语中，以引起听者或读者对某个特定信息的注意。常见的强调句结构包括“It is/was...that/who...”句型。
一、总结
强调句句型的主要功能是将句子中的某一部分（如主语、宾语、时间、地点等）从句子中独立出来，使其更加突出。这种句型不仅有助于增强语言的表现力，还能帮助说话者更清晰地传达重点。
以下是几种常见的强调句句型及其用法：
| 强调内容 | 句型结构 | 举例说明 |
| 主语 | It is/was + 主语 + that/who + 其他部分 | It was John who broke the window. |
| 宾语 | It is/was + 宾语 + that/who + 其他部分 | It was the book that I lost. |
| 时间 | It is/was + 时间 + that + 其他部分 | It was yesterday that we met. |
| 地点 | It is/was + 地点 + that + 其他部分 | It was in the park that we had lunch. |
| 方式 | It is/was + 方式 + that + 其他部分 | It was by bus that he came. |
二、使用注意事项
1. 时态一致：强调句中的“is”或“was”要与原句的时态保持一致。
- 原句：He called me yesterday.
- 强调句：It was yesterday that he called me.
2. 人称代词：当强调的是人时，使用“who”，否则使用“that”。
- It was she who helped me.
- It was the teacher that gave the speech.
3. 避免重复：强调句虽然能突出重点，但不宜过度使用，以免显得生硬或不自然。
三、常见错误对比
| 正确用法 | 错误用法 | 原因 |
| It was Tom who did it. | It was Tom that did it. | 当强调的是人时，应使用“who”。 |
| It was in the library that I found the book. | It was in the library where I found the book. | “where”不能用于强调句中。 |
| It was last week that we went to the beach. | It was last week when we went to the beach. | “when”不能用于强调句中。 |
四、实际应用示例
- 日常对话：
- A: Who gave you the gift?
- B: It was my sister who gave me the gift.
- 写作中：
- The success of the project was due to the team’s hard work, not just one person.
- It was the team’s hard work that led to the project’s success.
通过合理使用强调句句型，可以使语言表达更加生动、有力，同时也能让信息传递更加精准。掌握这一句型，有助于提升英语表达的层次感和逻辑性。
